N America uniforms linked to "forever chemicals"

A study of school uniforms in the US and Canada reveals high levels of so-called "forever chemicals". The chemicals, known as PFAS, are used to make clothing resistant to

stains or water but they have been linked to asthma, obesity and fertility issues. Researchers found that uniforms made with 100% cotton showed higher levels than synthetic

materials. Exposing children to these chemicals may increase the long-term health risk, the scientists believe. The issue is less of a concern in the UK because

almost all retailers' own brand uniforms are PFAS free, say campaigners. Possible breakthrough to destroy 'forever chemicals' UK's safe level for tap water too high -

scientists 'Forever chemicals' over safe levels in rainwater From fire-fighting foams to food packaging and textiles, PFAS chemicals are widely used because of their non-stick

and water-resistant properties. But researchers have long been concerned about these chemicals, known as per- and polyfluoroalkyl substances - because they don't break down

under normal environmental conditions. These "forever chemicals", which number in the thousands, persist in soil and water. However they can also accumulate in the human

body when ingested. While direct evidence linking them to health problems is mixed, scientists are concerned about exposure, particularly in young people whose lower body

weight and sensitive development may result in a greater lifetime threat. This latest study focusses on the contact with the chemicals that may occur as a result of wearing

school uniforms.
