A Toxics-Free Future


COVID-19 and Chemicals

SARS-CoV-2, the virus that causes the COVID-19 disease, has infected millions of people worldwide and has killed hundreds of thousands1. The pandemic has galvanized the global scientific and medical communities, resulting in over 21,000 scientific publications in just the first 6 months of 2020.

An important early conclusion is that the severity of COVID-19 is dependent upon the pre-existing health condition of the patient that compromises the ability to fight the disease.

According to the U.S. Center for Disease Control, the most common pre-existing conditions associated with severe disease include chronic obstructive pulmonary disease, obesity, coronary artery disease, and diabetes. Importantly, these chronic diseases are also linked to hazardous chemical exposures – especially chemicals that interfere with the endocrine system.

Endocrine Disrupting Chemicals (EDCs) are identified by their ability to cause harm by interfering with our hormone systems2, 3. Unfortunately, EDCs surround us in our daily lives, and include chemicals used as flame retardants, in plastics production, in food packaging, in pesticides, and in other applications. Communities exposed to more of these hazardous chemicals have been shown to have higher rates of these pre-existing chronic diseases. Thus, EDC exposure compounds the harm and impact of COVID-19.

Some argue that if an EDC caused an adverse effect, then everyone exposed would exhibit that effect. But this is like saying that if cigarettes cause cancer, then everyone who smokes would have cancer. In addition, because not everyone smokes, studies can compare cancer rates in the smoking population with that of the population of non-smokers. This strategy is not possible for many EDCs because everyone is exposed – there is no unexposed comparison population. Finally, we are exposed to a mixture of hundreds of chemicals – even at birth4, without our knowledge or permission5. Both smoking and EDCs are hazardous to your health and should be avoided.

It is also important to recognize that exposures to EDCs exert a toll not only on health but on the economy6-10. Thus, countries with developing economies and economies in transition that have a burden of chronic disease attributable to EDC exposures, are also facing more significant severe disease in relation to COVID-19. Data from the United States clearly show this trend.11

The relationship between COVID-19 disease severity and EDC exposures clearly demonstrates that current government policies are not protecting our health. The data from COVID-19 deaths reveal that EDC exposure has a direct effect on health, and also compromises the ability of whole populations to respond to a pandemic. Human populations need to be protected from EDC exposures, and the old business model based on risk assessment procedures have failed us. Known EDCs should be replaced with safe alternatives. People should be provided with information that helps them make choices, much like cancer warnings on cigarettes packages. COVID-19 has highlighted the failures in public health policies and the need to protect us from hazardous EDCs.
