A recent report has warned that chemical pollution poses a significant threat to human health and the environment, comparable to climate change, yet receives relatively little attention. The industrial economy has created over 100 million synthetic chemicals, with many in commercial use, which have severe environmental and health impacts.
The study found that nearly 3,600 synthetic chemicals from food contact materials are present in human bodies, 80 of which are considered significant concerns. Per- and polyfluoroalkyl substances (Pfas), also known as “forever chemicals,” have been detected in almost all humans tested and can be found in rainwater.
The report highlights correlations between widespread chemical exposure and various health issues, including reproductive problems, immune system damage, neurological disorders, and cardiovascular disease. Exposure to pesticides has been linked to miscarriage and difficulties conceiving.
Current toxicity assessment methods are also being criticized for their shortcomings, which may lead to missed effects of chemicals. The assessment of endocrine-disrupting chemicals, in particular, is flawed due to nonlinear responses that can occur at low doses.
To address this issue, innovators must prioritize chemical safety. However, the report suggests that consumer-driven demand for safer products could be a key driver of change. With some individuals already taking steps to reduce their exposure to chemicals by cooking with cast-iron skillets and avoiding heating food in plastic, there is potential for collective action through purchasing decisions.
The findings add to previous research indicating that we have exceeded the safe planetary boundary for environmental pollutants, including plastics.
