Organophosphorus chemistry is the scientific study of the synthesis and properties of organophosphorus compounds, which are organic compounds containing phosphorus. They are used primarily in pest control as an alternative to chlorinated hydrocarbons that persist in the environment. Some organophosphorus compounds are highly effective insecticides, although some are extremely toxic to humans, including sarin and VX nerve agents. WitrynaOrganophosphate esters are mostly chemical additives just mixed with containing materials, and so are prone to being released into the surrounding environment [163].Among these additive organophosphate compounds are the chlorinated organophosphate (OP) esters, namely tris(1,3-dichloro-2-propyl) phosphate …
