Organotin Compounds and the Environment
Organotin compound that have at least one Sn-C bond have wide commercial applications as PVC stabilizer, antifouling agent in paint and as agrochemicals. The general formula for organotin compounds is R4SnX4 - n where R is normally alkyl or aryl groups and X=Cl-, OH-, CH3COO- . If n=3, the compound has the highest toxicity, for example Et3SnOAC has LD 50 4mg/Kg ( rats ) and this is the m...

متن کاملOrganotin compounds: industrial applications and biological investigation.
According to Ross (1), there are three main areas in which organotin compounds have product and process utility: (1) heat stabilizers; (2) catalytic agents; (3) biocidal compounds. Organotin derivatives account for the fourth largest production of organometallics amounting to about 3-4 million pounds per year as compared with about 485 million pounds per year for organolead compounds. Originall...
متن کاملSpeciation analysis of organotin compounds by HPLC-ICP-MS
The toxicity of trace metals in our food, in the products we use and in the environment is an area of increasing concern. As our knowledge has grown, we have come to understand that the toxicity of these elements is highly dependent on the molecular species to which they are chemically bound. Increasingly, regulations are being written to reflect this reality. Monitoring elemental species requi...
