A “human biomonitoring” study, jointly conducted by the German Environment Ministry and the Robert Koch Institute, is sounding the clarion warning that plastic pollution is present — and not just in our oceans, estuaries and the fish we eat. Rather alarmingly, the study found toxic levels of plastic byproducts in 97 percent of the blood and urine samples gathered from 2,500 children tested.

The children in the research study ranged from 3 to 17 years of age. Of the 15 plastics under scrutiny, researchers detected 11 in the children’s test samples. Presence of these plastic byproducts in the children’s bodies increases their risk of hormonal dysfunction. That’s because plastics, at the micro level, can mimic the action of particular hormones, thus confusing the human endocrine system. The disruption, in turn, can manifest as obesity, metabolic disease, cancers, reproductive disorders, behavioral aberrations or developmental delays.

What’s disquieting is that exposure to these plastic substances can arise from the most mundane things — storage containers, DVD cases, receipts, package linings, PVC piping, imitation leather, treated furniture, carpeting, even toys and medical devices. Plastics and microplastics surround us; consequently, we cannot avoid being exposed.

One of the scientific authors, Marike Kolossa-Gehring, stated, “Our study clearly shows that plastic ingredients, which are rising in production, are showing up more and more in the body.”

The study also revealed that the most susceptible subjects were younger children and children from poorer families. Both at-risk groups registered more plastic residue than their counterparts.

Similarly, the study addressed the issue of replacements, citing that substances classified as perilous to humans should not be replaced by similar chemicals. After all, the substitutes might be just as toxic and detrimental. Hence, replacing with similar chemicals does not mitigate the chances of being exposed to harm.

Researchers expressed uneasiness about the high levels of perfluorooctanoic acid (PFOA) in the young subjects. The apprehension surfaces from the fact that PFOA is extremely persistent, bioaccumulative and rather toxic. PFOA is typically used in the process for making Teflon, which explains why it is usually found coating non-stick cookware and waterproof clothing. PFOA is a threat because it is toxic to both the reproductive system and the liver. The European Union is expected to ban PFOA in 2020.

The scientists concluded that more research is needed to discover the pathways that plastics take to enter the human body. A solution is likewise needed to minimize the risks of children accumulating plastic byproducts at unsafe levels.
