چکیده
Tin and organotin compounds have been identified in at least 214 and 8 sites, respectively, of the 1,662 hazardous waste sites that have been proposed for inclusion on the EPA National Priorities List (NPL) (HazDat 2004). However, the number of sites evaluated for tin and organotin compounds is not known. The frequency of these sites can be seen in Figures 6-1 and 6-2, respectively.
