PCB warning label on a power transformer known to contain PCBs. Polychlorinated biphenyls (PCBs) are organochlorine compounds with the formula C 12 H 10−x Cl x; they were once widely used in the manufacture of carbonless copy paper, as heat transfer fluids, and as dielectric and coolant fluids for electrical equipment.

In computers, BFRs are used in four main applications: in printed circuit boards, [7] in components such as connectors, in plastic covers, and in electrical cables. BFRs are also used in a multitude of products, including, but not exclusively, plastic covers of television sets, carpets, pillows, paints, upholstery, and domestic kitchen appliances.
Polybrominated diphenyl ethers or PBDEs, are a class of organobromine compounds that are used as flame retardants.Like other brominated flame retardants, PBDEs have been used in a wide array of products, including building materials, electronics, furnishings, motor vehicles, airplanes, plastics, polyurethane foams, [1] and textiles.
Additionally, experts advise against microwaving or heating food in black plastic containers, as heat can exacerbate the leaching of harmful chemicals. Instead, transferring food to glass or ...
Bisphenol A (BPA) is a chemical compound primarily used in the manufacturing of various plastics. It is a colourless solid which is soluble in most common organic solvents, but has very poor solubility in water. [2] [7] BPA is produced on an industrial scale by the condensation reaction of phenol and acetone. Global production in 2022 was ...
For example, products containing brominated flame retardants have been incorporated into new plastic products. Flame retardants are a group of chemicals used in electronic and electrical equipment, textiles, furniture and construction materials which should not be present in food packaging or child care products.
“In the current study, researchers found high levels of bromine — and thus suspected contamination from brominated fire-retardant chemicals — in just around 10% of the black plastic ...
Researchers found toxic flame retardants in 85% of the screened consumer products Black Plastic Kitchen Utensils, Takeout Containers — Even Toys — Linked to Cancer-Causing Chemicals Skip to ...
