Chemicals in food packaging can migrate into food — especially when the food is hot, fatty, or stored a long time. Here’s what the main ones are, how transfer happens, and simple ways to reduce contact.

Endocrine disruptors are chemicals that can interfere with hormone systems. They’re found in some plastics, personal care products, pesticides, and other everyday items. Here’s what they are, why timing of exposure matters, and practical ways to reduce contact.

Phthalates are chemicals used to soften plastics and to make fragrances last longer. They can leach into food, dust, and personal care products, and they’re linked to hormone-disrupting effects. Here’s where they show up and how to reduce everyday exposure.

Pesticides kill or control pests; herbicides target weeds. They’re widely used in homes, gardens, and agriculture. Here’s where common ones show up, the main exposure routes, and practical ways to reduce contact while still dealing with pests.

Lead-based paint is still common in homes built before 1978. The real hazard is usually the dust and chips that form when the paint deteriorates or gets disturbed. Here’s where it shows up and how to reduce the risk, especially for young children.

Microplastics are plastic particles smaller than 5 mm that now appear in water, air, food, and the human body. Most form when larger plastics break down. Here’s a clear look at what they are, where they come from, and what is known so far about their effects.

BPA is an industrial chemical used to make certain plastics and the linings inside many food cans. It can act like a weak estrogen in the body. Here’s a clear look at where it shows up, how it differs from common replacements like BPS, and practical ways to reduce exposure.

Persistent organic pollutants (POPs) are toxic chemicals that last a long time in the environment, build up in living things, and can travel long distances. Many of the original ones are now banned, but they still linger. Here’s a clear look at what they are, why they matter, and what’s been done about them.

“Forever chemicals” is the nickname for a group of human-made substances that resist breaking down in the environment and in our bodies. Most often it refers to PFAS. Here’s a clear look at what the term actually means, where these chemicals show up, and what practical steps can lower exposure.

PFAS are a large group of human-made chemicals that resist heat, water, and stains — and also resist breaking down. Here’s a clear look at what they are, where they show up in everyday life, why they persist, and what practical steps can lower exposure.
