Removing PFAS from public water systems will cost billions and take time – here are ways to filter out harmful ‘endlessly chemicals’ at home

Published

on

Chemists invented PFAS within the Nineteen Thirties to make life easier: PFAS made it possible to make nonstick pans, waterproof clothes, grease-resistant food packaging, and stain-resistant carpets. However, in recent times, the growing variety of health risks related to these chemicals have grow to be increasingly concerning.

PFAS – perfluoroalkyl and polyfluoroalkyl substances – are currently suspected or he is understood to contribute for thyroid disease, high cholesterol, liver damage and cancer, amongst other health problems.

They may be present in the blood most Americans and in lots of drinking water systems, which is why the Environmental Protection Agency finalized work on it in April 2024 first enforceable federal limits for six forms of PFAS in drinking water systems. The limits – 4 to 10 parts per trillion for PFOS, PFOA, PFHxS, PFNA and GenX – are lower than a drop of water in a thousand Olympic-sized swimming pools, demonstrating the toxicity of the chemicals. The sixth type, PFBS, is regulated as a mix using the so-called threat indicator.

Meeting these recent limits will not be easy or low cost. There’s one other problem: While PFAS may be filtered from water, these “forever chemicals” are difficult to destroy.

My team at the University of Notre Dame works to address contaminants in water systems, including PFAS. We are investigating recent technologies to remove PFAS from Potable water and to address PFAS waste. Here’s a glance at the dimensions of the challenge and how to reduce PFAS in your personal drinking water:

Removing PFAS will cost billions annually

Every five years, the EPA is required to select 30 unregulated pollutants to monitor in public drinking water systems. Currently, 29 of those 30 contaminants are PFAS. Testing gives a way of how common PFAS are in water systems and where.

The EPA collected 22,500 samples from roughly 3,800 of the 154,000 public drinking water systems within the US. In 22% of those water systems, testing detected at least one in every of the six newly regulated PFASs, and roughly 16% of the systems exceeded the allowable standards. recent standards. East Coast states had the very best percentage of systems with PFAS levels that exceeded the brand new standards in EPA tests conducted to date.

Under the brand new EPA regulations, public water systems have until 2027 to complete PFAS monitoring and release publicly available data. If they detect PFAS in concentrations above the brand new limits, they will have to install a treatment system by 2029.

How much this will cost public water systems, and ultimately their customers, continues to be the large unknown, however it won’t be low cost.

The EPA estimated the prices to the nation’s public drinking water systems to comply with information rules at a cost of roughly $1.5 billion annually. But other estimates suggest that the general costs of testing and remediating PFAS contamination will be much higher. The American Water Works Association has set the cost at over $3.8 billion annually just for PFOS and PFOA.

There are over 5,000 chemicals which are considered PFAS, nevertheless, only a couple of have been tested for his or her toxicity and even fewer have been tested for presence in drinking water. This is estimated by the United States Geological Survey almost half of all tap water is contaminated with PFAS.

Some money for testing and clean-up will come from the federal government. The remaining funding will come from 3M and DuPont, leading PFAS producers. 3M agreed to pay within the settlement $10.5 to $12.5 billion to help reimburse public water systems for certain PFAS testing and treatment. However, public water systems will still incur additional costs that will be passed on to residents.

Next problem: disposal of “forever chemicals”

Another vital query is how to eliminate captured PFAS once it has been filtered out.

The creation of landfills is being considered, but this only shifts the issue to the subsequent generation. There’s a reason why PFAS are called “forever chemicals” – they are extremely durable and don’t decompose naturally, making them difficult to destroy.

Studies have shown that PFAS may be broken down using energy-intensive technologies. But this comes with huge costs. The incinerators must arrive over 1,800 degrees Fahrenheit (1,000 degrees Celsius) destroy PFAS, and potentially harmful byproducts could also be produced not fully understood yet. Other suggested techniques e.g supercritical water oxidation Or plasma reactorsthey’ve the identical disadvantages.

So who’s chargeable for managing PFAS waste? Ultimately, responsibility will likely fall on public drinking water systems.

EPA on April 19, 2024 designated PFOA and PFOS as contaminants qualifying for Superfund statusmeaning firms chargeable for polluting sites with these chemicals may very well be required to pay for cleanup. However, the EPA found this out I had no intention of following him sewage treatment plants or public landfills.

Steps to protect your home from PFAS

Your first instinct could also be to use bottled water to avoid exposure to PFAS, but a recent study found this even bottled water may contain these chemicals. Bottled water is regulated by one other federal agency, the Food and Drug Administration, which has no standards for PFAS.

The best choice is to depend on the identical technologies that processing plants will use:

  • Activated carbon it is comparable to charcoal. Like a sponge, it captures PFAS, removing it from the water. This is identical technology utilized in refrigerator filters and some jug filters, equivalent to Brita or PUR. Please note that many refrigerator manufacturers’ filters are not certified for PFAS, so don’t assume they will remove PFAS to secure levels.

  • Ion exchange resin this is identical technology present in many home water softeners. Like activated carbon, it captures PFAS from water, and this technology may be present in many pitcher filter products. If you select to the entire house purification system that a plumber can connect where the water enters the home, an ion exchange resin will probably be the most effective selection. But it’s expensive.

  • Reverse osmosis is a membrane technology that permits only water and chosen compounds to go through the membrane, while PFAS are blocked. This is usually installed at the kitchen sink and has been turned out to be very effective when removing most PFAS from water. This is not practical for cleansing your entire house, however it will likely remove many other contaminants as well.

If you have got a personal well as an alternative of a public drinking water system, it doesn’t mean you are secure from PFAS exposure. The Wisconsin Department of Natural Resources estimates so 71% shallow private wells on this state they’ve some level of PFAS contamination. Using a licensed lab to test well water for PFAS can cost $300-$600 per sample, a cost barrier that will leave many private well owners at the hours of darkness.

For all treatment options, ensure that the device you select is PFAS certified by a good testing agencyand follow the really helpful filter maintenance and substitute schedule. Unfortunately, there may be currently no secure way to eliminate filters, in order that they find yourself within the trash. No treatment is ideal and none will remove all PFAS to secure levels, but some treatment is healthier than no treatment at all.

More than half of party drug users take ADHD medication without a prescription, new study finds

Published

on

By

Each 12 months, the National Drug and Alcohol Research Centre on the University of New South Wales in Sydney surveys a whole bunch of regular drug users in Australia to seek out out understand trends within the use of psychoactive substances throughout the country.

Today we published Report 2024during which 740 people from Australian capital cities who usually use ecstasy or other illegal stimulants were surveyed.

While the first focus of our research is illicit drugs and markets, we also monitor trends within the over-the-counter use of pharmaceutical stimulants, resembling ADHD medications.

This 12 months, 54% of people we spoke to had used pharmaceutical stimulants previously six months after they weren’t prescribed them, the best percentage now we have seen since we began asking people about this kind of drug use in 2007.

What are pharmaceutical stimulants?

Pharmaceutical stimulants include the drug methylphenidate (trade names Concerta and Ritalin), in addition to dexamfetamine and lisdexamfetamine (Vyvanse).

These medications are commonly prescribed for the treatment of attention deficit hyperactivity disorder (ADHD) and narcolepsya chronic neurological disorder that causes excessive sleepiness and sudden sleep attacks through the day.

These drugs work in other ways depending on the kind. However, they treat ADHD by increasing levels of necessary chemicals (neurotransmitters) within the brain, including dopamine and norepinephrine.

However, as with many pharmaceutical substances, people also use these stimulants after they should not prescribed. There is range of reasons someone may select to make use of these medications without a prescription.

Tests University students have shown that these substances are sometimes used to extend alertness, concentration and memory. Studies conducted amongst wider populations have shown that they may also be used experimentor to get high.

All over the world, including in Australiawere significant increases within the prescription of ADHD medications lately, likely on account of increased identification and diagnosis of ADHD. As prescriptions increase, the danger of these substances being diverted to illegal drug markets increases.

Some people may seek pharmaceutical stimulants to extend alertness and concentration.

What we found

The percentage of people using stimulants without a prescription has tripled since monitoring began – from 17% of respondents in 2007 to 54% in 2024. It has remained at a similar level lately (52% in 2022 and 47% in 2023).

Frequency of use remained relatively low. Respondents typically reported using non-prescribed pharmaceutical stimulants monthly or less continuously.

In this study, participants most continuously reported using dexamfetamine, followed by methylphenidate and lisdexamfetamine. Most (79%) said it was “easy” or “very easy” to acquire these substances, just like 2022 and 2023.

Of course, provided that our study focused on regular drug users, the over-the-counter use of pharmaceutical stimulants doesn’t reflect their use in the final population.

In 2022–2023 National Household Drug Strategy Surveygeneral population survey of Australians aged 14 years and over, 2.1% of the population (comparable to about 400,000 people) reported using pharmaceutical stimulants for non-medical purposes within the previous 12 months. This was just like the proportion of people reporting using ecstasy.

What are the risks?

Pharmaceutical stimulants are considered to have a relatively secure toxicity profile. However, like all stimulants, these substances increase activity sympathetic nervous systemwhich controls various functions within the body during times of stress. This in turn increases heart rate, blood pressure and respiration rate.

These changes may cause acute cardiac events (resembling arrhythmias or irregular heartbeats) and, with repeated use of high doses, chronic changes in heart work.

Recent Australian research has documented increase in poisoning involving these substances, although a significant proportion of these seem like intentional poisonings. In the poisonings that involved only pharmaceutical stimulants, the drugs were mostly taken orally, with the median dose being more than ten times the everyday prescribed dose. The commonest symptoms were hypertension (hypertension), tachycardia (fast heart rate), and agitation.

In our study, individuals who took pharmaceutical stimulants most frequently took them in pill form, taking a dose barely higher than that typically prescribed.

However, about one in 4 people reported snorting as a route of administration. This can lead to physical harm, resembling damage to the sinuses, and will increase the potential risks of the drug because it will possibly come into effect faster within the body.

Some pharmaceutical stimulants are “long-acting,” released into the body throughout the day. So there may additionally be a risk of premature re-dosing if people unknowingly use these preparations more than once a day. That is, if people don’t experience desired effects They may take one other dose on the expected time, which can increase the danger of uncomfortable side effects.

Finally, non-prescribed stimulants can have negative effects when taken with other medications. This can include a “masking effect” (for instance, a stimulant may mask the symptoms alcohol poisoning).

So what should we do?

Pharmaceutical stimulants are necessary medications within the treatment of ADHD and narcolepsy, and when used as directed, they’re relatively secure. However, there are additional risks when people use these substances without a prescription.

Harm reduction campaigns that highlight these risks, including differences between formulations, will be useful. Ongoing monitoring, alongside more in-depth investigation of associated harms, can also be key.

Shortly after Labor Day, the consummate entertainer Usher played 4 consecutive sold-out shows in Brooklyn, New York, as a part of his . For two hours each night, he danced, sang, poured drinks for fans (you only needed to be there), and partied with special musical guests, all while his skin glowed. And not simply because he was sweating, although he was sweating loads. But also since the star, who has been around for 3 many years, has flawless skin at age 45. How does he do it?

With proper skincare and the assistance of hairdresser, Lola Okanlawon.

I had the chance, together with a gaggle of journalists and public opinion influencers, to hearken to the speech of Okanlawon, a famous make-up artist and licensed dermatologist DiAnne Davis, MDconcerning the tricks to having an unparalleled skincare routine, and all of it revolves around the suitable products. In addition to dancing with Usher, our presence that evening was also to have a good time the launch of a skincare brand Ceravelatest Eye cream with skin renewing vitamin Cwhich joins their popular Skin Renewing line. Usher uses it, and Davis says it’s best to too.

“Their whole Skin Renewing line really helps target some of the things that you might start to notice as you get a little older,” the plastic surgeon and skincare expert shared. “So maybe you’ve lost a little elasticity, or maybe your skin tone isn’t even, or maybe you’ve noticed a few fine lines and wrinkles here and there. That’s what this Skin Renewing line is all about.”

The key ingredients of the brand new eye cream are hyaluronic acid, which moisturizes, ceramides, which protect and moisturize the skin, caffeine, which reduces puffiness under the eyes, and five percent vitamin C, which brightens the skin across the eyes without irritating it.

(*45*) she says.

Okanlawon visited the artist before ending Usher’s pre-concert styling and opened up about her collaboration with the star, with whom she has been in a relationship for 3 years.

“I take care of all of his skin, from head to toe,” she told us, noting that they’re each fans of Cerave, which she uses often to prep him for the cameras and the massive stage.

“It’s important to have a skin prep routine before you go on stage. This man doesn’t play with his skin or his body,” she shared. “It’s nice to have a man who cares about his skin and cares about his appearance, buys products and asks me about them. ‘Hey, what about this? What about this?'”

The MUA star then delved into the practices and routines that keep her glowing, which include monthly facials (“This is not a game”) and a really, very clean food regimen.

“Of course, we start with a foaming cleanser because I do his stage makeup so that his hairline and certain things stay intact because he sweats a lot,” she says. “If you haven’t seen Usher perform, it’s like a waterfall. So I placed on some makeup that principally won’t come off together with his sweat. Moisturizing foaming cleansing oil It’s amazing since it breaks down product, it breaks down dirt, it breaks down oils, in order that’s definitely where we start.”

Next up is a brand new vitamin C eye cream. Okanlawon received the product ahead of its September launch and has been using it often on the star’s eyes for several months. She says it’s a must have in any skincare routine.

“Usher is a very good, handsome man. But he’s still 45, so eye cream is very important, and eye cream with vitamin C is amazing,” she says. “It’s preventative, so don’t wait until a certain age. Start using eye cream.”

Then they use Vitamin C Serum and finish your pre-makeup workout by moisturizing your body with Cerave Daily Moisturizing Balmwhich apply together.

“We use serum because serum is very important. Vitamin C helps brighten the skin,” she says. “His skin is very elastic because he takes good care of it. It’s easy, he’s easy.”

What Usher does night after night in front of packed audiences is not easy, but with guidance from Okanlawon and Cerave’s Skin Renewing line of beauty products, she all the time looks gorgeous when she does it.

The Way We Think About “Obesity” and Body Weight Is Changing, Here’s Why

Published

on

By

From doctor’s offices to family gatherings, larger people report being bombarded unsolicited advice about their eating and exercise habits. The underlying message? “They just need to lose weight” to solve almost any health problem.

Society’s give attention to weight has shaped the best way most Australians view health and body weight, which frequently pushes them towards unhealthy thoughts and behaviors in pursuit of the “perfect” figure.

However, the best way society views obesity and body weight is changing, and these changes are being confirmed by science.


*


Policymakers and health researchers are increasingly recognizing the harmful effects stigmatizing language and attitude towards individuals with a bigger physique.

Let’s have a look at how attitudes towards obesity have modified through the years and what this implies for public health and healthcare in Australia.

From Personal Responsibility to Complex Chronic Illness

Until recently, weight control was it will likely be considered a private responsibilityObesity was believed to be the results of poor eating regimen and lack of physical activity, coupled with personal and moral failure.

This narrative was reflected in public health policy, which used phrases similar to “he was obese“and the “epidemic of o*c*lness”. It has been shown that such language reinforce negative stereotypes people with larger builds as “lazy” and lacking willpower.

These stereotypes result in stigmatization and weight discrimination, which is still common today. Health professionals similar to dietitians report that Weight stigma (from other people and internally) is a standard and ongoing challenge that ladies need to cope with throughout their careers.

The narrative around personal responsibility has modified lately because it begins to think about broader determinants of health. Research has identified a spread of psychological, social, biological and systemic aspects contribute to rising rates of obesity, similar to socioeconomic status, genetics, medications and environment.

As a result, public health experts consider that is not any longer appropriate use language that refers to obesity as a “lifestyle” issue.

Until recently, weight management was seen as a private responsibility.
World Obesity Federation

Professionals throughout medicine, psychology and dietetics additionally they responded by updating their language standards to prioritize person-first language (for instance, “person living with o*b*lihood”), recognizing a shift away from viewing o*b*lihood as a private failure.

In 2014, the American Medical Association of the United States classified obesity as a chronic diseasecontrary to the recommendations of the Science and Public Health Committee. The decision has sparked widespread dissatisfaction and debate, with claims that it causes unnecessary discrimination and pathologizes normal changes within the human body over time.

The debate continues here in Australiabut no classification has yet been made.

Weight-focused and weight-sensitive narratives

Recent policy documents in Australia similar to National Anti-Obesity Strategy 2022–2032acknowledge the broader perspective of o*b*st. But the policy and practice in Australia remain mainly focused on weight. They encourage weight reduction as a health goal and recommend deliberately avoiding weight gain.

Weight-Focused Approaches to Health They were criticized for the dearth of long-term (longer than five years) evidence of their effectiveness and for causing unintended effects.

Rather than promoting health, weight-focused approaches could cause harm, similar to increased weight stigma and weight cycling (repeated weight reduction and regain). Both weight mark AND weight cycles are related to negative long-term effects on physical and mental health.

Weight-sensitive approaches to health are gaining popularity instead approach that supports people to eat healthily and exercise repeatedly, no matter their desire to shed weight. This approach goals to enhance access to health care and has been shown to enhance overall physical and mental health.

Approaches similar to Health at every size and intuitive eating are key examples of promoting health and wellness without specializing in weight.

Weight-sensitive approaches have he was met with criticismHowever, there are concerns that these approaches will not be supported by empirical evidence and might not be suitable for people needing support with weight management.

What does this mean for us?

While our views on obesity are always changing, it is crucial to hearken to plus-size people and ensure they’ve equal, protected and satisfactory access to healthcare.

Advocates like Size Inclusive Health Australia recommending actions to cut back weight-related stigma and discrimination in order that health is inclusive of all body shapes and sizes.

There are guidelines and recommendations on counter weight stigma and adopt a weight-sensitive approach to health, similar to: Size-sensitive health promotion guidelines and Eating Disorder Safety Guidelines.

Policy, research and practice should proceed to synthesise and understand the evidence surrounding weight-sensitive approaches, in keeping with changing narratives around weight and health. This will support the design, implementation and evaluation of weight-sensitive initiatives in Australia.
