CHEMICAL EDUCATION
What's Actually In the Stuff in Your House.
Most chemicals in consumer products were never tested for safety before they hit shelves. The Toxic Substances Control Act, passed in 1976, grandfathered roughly 60,000 industrial chemicals with no review [regulatory review]. The EPA has fully restricted nine of them since. So when a product label says non-toxic, it usually means non-toxic by the manufacturer's own definition. This section explains what the chemicals you've been hearing about (PFAS, phthalates, flame retardants, VOCs, formaldehyde, microplastics) actually are, what they do inside the body, what dose matters, and which products are worth swapping first. We mark every health claim with a study type ([animal study], [human epidemiological], [in vitro], [meta-analysis]) so you can tell mechanistic data from human evidence. The goal is calibration, not alarmism.
