Industrial Hygiene Study: Extent of Exposures to Organotins.
An industrial hygiene assessment was made of occupational exposures to organotin compounds. There were two major areas of use for these chemicals, biocidal uses such as pesticides and antifouling coatings and nonbiocidal uses including stabilizers and catalysts. There were also some minor uses such as antioxidants and metal plating agents. The OSHA permissible exposure limit PEL for organotins was chosen for on site exposure measurement visits including a producer of triorganotin compounds with potential biocidal applications, a formulator of a triorganotin containing miticide, and a user of a triorganotin containing antifouling paint. At each location personal breathing zone samples and area air samples were taken. Time weighted average full shift exposures to organotin compounds ranged from below the limit of detection to 2.9mg/m3 as tin. For the most part, personal protective equipment was used when concentrations exceeded the OSHA limit. The author concludes that exposure levels in excess of 0.1mg/m3 are likely to be found in employment activities involving transferring, blending, or packaging of raw organotin containing products or during the application of an organotin containing product involving aerosolizing the product. Workplace exposure populations were too small for a reproductive study.
