Toxicities of Triorganotin Compounds
Tin is a ubiquitous element. Our bodies contain 0.2 ppm [26, 27]. We ingest
0.2 ppm based on kg body weight from daily foods [28]. Inorganic tin at trace
level has never been implicated in plant and animal malfunctions and on the
whole has been assumed to be an innocuous background material [29]. Most
