Lessons on PFAS emergence as environmental toxicant

March 3, 2023

The perfluorinated alkylate substances (PFASs) were introduced as industrial chemicals about 1950, with important uses for non-stick kitchen utensils and, with time, many other useful purposes. During the early decades, studies were conducted that suggested possible toxicity, but they were not published and apparently resulted in little prevention. About 2000, previously hidden documentation was released and began to stimulate academic research, but it took may years to explore the toxic properties of these persistent compounds, with focus on the most common PFASs. Agency responses were delayed, and exposure limits have decreased substantially over time. Alternative PFASs have been introduced, but are they as toxic as the legacy compounds? The PFAS history illustrates weaknesses and concerns about our current approach to controlling exposures to toxic substances.

The precautionary principle also applies to science

March 2, 2023

For various reasons, public health science focuses on a limited number of preventable risks related to voluntary and non-voluntary exposures, such as metals. Conclusions are often hedged or understated, and results tend to be descriptive, rather than analytic. Non-significant associations are said to be “negative”, and academic tradition seems to support replication rather than innovation. In contrast, the precautionary principle would emphasize evidence that supports a judgment whether a risk factor may lead to adverse effects that are serious enough to initiate procedures to decide on intervention.

Critical effects in environmental health may not be critical

February 13, 2023

Protection against environmental hazards usually aims at protecting against so-called critical effects that occur at the lowest exposures in a vulnerable population. That assumes the existence of evidence that allows a choice between potential adverse effects. Perhaps one can rely on experimental results, but human data are usually preferred. This is where the main uncertainty occurs, and it is critical.
