Plastic food packaging is increasingly coming under scrutiny for potentially exposing individuals to harmful chemicals, such as bisphenol A (BPA). Recent research suggests that these chemicals could be linked to hundreds of thousands of deaths and millions of heart disease cases globally, underscoring the urgent need for more stringent regulations on toxic substances in consumer products.
Researchers have studied the public health impact of three key chemicals used in plastics: BPA, di(2-ethylhexyl) phthalate (DEHP), and polybrominated diphenyl ethers (PBDEs). BPA and DEHP are prevalent in plastic food packaging, while PBDEs are used as flame retardants in various household products, including furniture and electronics.
Utilizing data from over 1,700 previously published studies, researchers examined exposure levels to these chemicals across 38 countries, accounting for approximately one-third of the global population. Notably, countries like the US, Canada, and South Korea maintain public databases that monitor chemical levels in urine and blood, which enhances data accuracy.
The analysis, combined with medical records and toxicology reports, revealed alarming health outcomes linked to these chemicals. In 2015 alone, approximately 5.4 million cases of coronary artery disease and around 346,000 strokes were associated with BPA exposure. Moreover, DEHP has been implicated in approximately 164,000 deaths among individuals aged 55 to 64.
Encouragingly, regulations implemented in the late 2000s have led to a decline in the prevalence of these chemicals in countries such as the US, Canada, and various European nations. Researchers estimate that about 515,000 deaths could have been averted if BPA and DEHP exposure levels in the US had remained at post-regulation levels since 2003. These findings highlight the critical role that governments and manufacturers play in limiting toxic chemicals in plastic products.
However, the researchers caution that these findings are approximations, noting a significant limitation due to the lack of exposure data in some regions. There is a call for improved monitoring of chemical exposures globally to enhance understanding of their impact on public health.
