Modern life surrounds us with synthetic chemicals. From the food we eat and the water we drink to the furniture we sit on and the personal care products we apply each morning, Americans now carry hundreds of synthetic compounds in their bodies — a phenomenon toxicologists call "body burden." The statistics below document the true scale of everyday chemical exposure in the United States and how it compares to other developed nations.

For more on one of the most pervasive chemical classes, see our PFAS statistics page.

Frequently Asked Questions

How many synthetic chemicals are registered for use in the U.S.?

Over 86,000 synthetic chemicals are registered for use in the U.S. under the EPA's TSCA inventory. Fewer than 1% of these have been fully tested for human health effects, and over 40,000 are classified as "exempt from TSCA reporting" meaning no production or use data is publicly available.

How many chemicals does the average American have in their body?

The CDC's NHANES biomonitoring program has found 212 or more synthetic chemicals in the average American's blood and urine, including PFAS, phthalates, bisphenols, flame retardants, pesticides, and heavy metals. This is widely considered an undercount since NHANES only tests for a subset of chemicals in commerce.

How many synthetic chemicals do Americans encounter before leaving home?

According to the Environmental Working Group, the average American is exposed to 100 or more synthetic chemicals before leaving home in the morning — from shampoo and toothpaste to off-gassing furniture, non-stick cookware, and food packaging. This does not include chemical exposures from commuting, workplace, or other environments.

Why does the U.S. lag behind the EU on chemical regulation?

The primary reason is the Toxic Substances Control Act (TSCA) of 1976, which placed the burden of proof on the EPA to prove a chemical is harmful before restricting it. The EU's REACH regulation inverts this model — requiring chemical manufacturers to prove safety before products enter the market. The EU has banned over 1,300 chemicals in cosmetics; the U.S. FDA has banned only 11.

Are children more vulnerable to chemical exposure?

Yes. Children carry higher body burdens of many chemicals relative to their body weight compared to adults, primarily due to hand-to-mouth behavior, proximity to floors and furniture where chemicals accumulate in dust, and developing metabolic systems that are less efficient at processing toxins. The American Academy of Pediatrics has called for stricter chemical regulations specifically to protect children's health.
