Eighteen kinds of soft contact lenses have detectable levels of organic fluorine, an indicator of the group of chemicals known as PFAS, according to a new report. An environmental wellness blog and community had contact lenses tested by a U.S.-Environmental-Protection-Agency-certified lab and found levels of organic fluorine ranging from 105 parts per million, or ppm, to 20,700 ppm.

While PFAS has become a predominant environmental health concern, they are not the only class of forever chemicals that pose a health risk. Rather, they belong to a diverse group of chemicals that share the property of being remarkably stable in the environment. Other persistent organic pollutants (POPs), which is the scientific term for forever chemicals, include polychlorinated biphenylsl (PCBs), dioxins and organochlorine pesticides like DDT. More:

Chemicals that were banned after they punched a hole in Earth’s ozone layer are still building up at an alarming rate in our atmosphere, according to research published today in the journal Nature Geoscience.

You may not be able to see PFAS molecules around you, but they are ubiquitous: in our food, leaching into our water supplies, and in our blood. The class of water-resistant compounds used to make raincoats waterproof and nonstick pans stick-proof are also known as "forever chemicals," so named because they do not naturally break down in the environment (or in our bloodstream).

As plastic littering in the environment is of great concern, the effects of littered biobased biodegradable plastics in aquatic habitats may be amplified by their capacity to interact with mercury (Hg). This study sought to understand better how ultraviolet (UV) ageing affects biobased polymers in water, and whether the amount of mercury that can attach to these polymers increases as a result.
