3 days ago · Properties. Microplastics consist of carbon and hydrogen atoms bound together in polymer chains. Other chemicals, such as phthalates, polybrominated diphenyl ethers (PBDEs), and tetrabromobisphenol A (TBBPA), are typically also present in microplastics, and many of these chemical additives leach out of the plastics after entering the environment.

5 days ago · Physical and chemical properties Physical properties. The compounds are pale-yellow viscous liquids. They are hydrophobic, with low water solubilities: 0.0027–0.42 ng/L for Aroclors brand, [page needed] but they have high solubilities in most organic solvents, oils, and fats. They have low vapor pressures at room temperature.
