Another pathetic PFAS study

PFAS is a class of chemicals that is totally harmless to humans. But because there is a lot of it around the do-gooders are determined to find something wrong with it. They have been at it for years -- always finding nothing like what they theorize. Attention-whore Erin Brockovich was one of the early players. The latest attempt is below. As usual, no harm from PFAS was found. But they scratched around in their data to find something to talk about

They were, fortunately, honest enough to admit that their reults were inconclusive.  But the results were more than inconclusive.  They totally vindicated PFAS.  I simply quote from the journal article:

"In the overall analyses, no associations were found between PFOA, PFOS, or PFHxS and the clinical lipid measurements when adjusting for age, sex, and education"

Get that:  NO ASSOCIATIONS



Toxic chemicals lurking in cookware, make-up and toiletries might be harming the heart, another study suggested today.

Scientists have for years warned about the dangers of perfluoroalkyl substances, or PFAS.

Dubbed 'forever chemicals' because they can linger in the environment for hundreds of years, they have been linked to everything from cancer to infertility.

But the latest evidence by Dutch and German researchers suggests that the impact of PFAS on human health could be even greater than suspected. 

Tests showed 'clear' signs PFAS led to higher levels of 'harmful' blood lipids, such as cholesterol and other fatty substances. 

Excess lipids or fats in the blood can increase the risk of heart attacks and strokes, studies show.

The findings do not prove the chemicals, added to cookware, carpets, textiles and other items to make them more water- and stain-repellant, cause any adverse heart issues because other factors could be at play.

Scientists said the results, however, should serve as a warning that 'there may be no safe levels below which exposure is without health hazard'.

Study author Professor Monique Breteler, director of population health sciences at German Center for Neurodegenerative Diseases (DZNE), said: 'We see clear signs of a harmful effect of PFAS on health. 

'We have found at the same PFAS concentration in the blood, the negative effects are more pronounced in younger subjects than in older ones.

'Our data shows a statistically significant correlation between PFAS in the blood and harmful blood lipids linked to cardiovascular risk.'

However, she noted: 'The higher the PFAS level, the higher the concentration of these lipids. 

'Taken strictly, this is not yet proof that PFAS chemicals cause unfavorable blood lipid profiles.'

PFAS are a class of chemicals that are more properly known as per and polyfluoroalkyl substances. 

Famed for their durability and stain resistant properties, they have been used in a host of products from nonstick cookware, to clothes, packaging, cosmetics and even children's toys. 

But industries are now moving away from them because of their detrimental impacts. 

When PFAS enter the body either through food and water that people eat and drink or by inhaling contaminated air, they can distribute throughout the body in tissues and organs.

PFAS has previously been linked to kidney cancer, prostate cancer and breast cancer, among others. 

While these links are not definitive and research is ongoing, part of the concern is because PFAS are so ubiquitous in modern life and persist so long in the environment they could infiltrate water supplies, further increasing exposure.

The Government's Drinking Water Inspectorate (DWI) currently sets a limit of 0.1 micrograms per litre (?g/L) for PFAS in UK tap water, with the body running a specific programme testing for levels in British water supplies.

In their study, researchers at DZNE and Leiden University Medical Center in the Netherlands analysed blood samples from over 2,500 Dutch men and women aged between 30 and 89. 

PFAS were detected in the blood of almost all test subjects.

Professor Breteler added: 'Even if we don't see an immediate health threat for the study participants we examined, the situation is still worrying. 

'In the long term, the increased risk may very well have a negative impact on the heart and cardiovascular system.'

The findings, based on three of the most common types of PFAS (PFOA, PFOS and PFHxS) were published in the journal Exposure and Health.
