[Comment] Plastics, plastic chemicals, and microplastics: multiple harms to health

Microplastics and nanoplastics (MNPs) are everywhere. These tiny particles—formed by abrasion, fragmentation, and open burning of plastics—are found in the ocean, the Arctic, Himalayan glaciers, air, food, and drinking water.1 More recently, they have been reported in human lung and faeces, reflecting exposures via inhalation and ingestion, as well as in blood, carotid arteries, heart, brain, liver, ovaries, testes, and placenta.2 Early clinical and epidemiological reports suggest associations b
