This study was conducted to assess the safety with special reference to the primary skin irritation, if any, of six samples (Excavated waste, Lime sludge, Naphthol tar (nor Naptho tar), Reactor residues, Semi processed pesticide and Sevin tar) collected from `Stored Toxic Wastes at the former UCIL Plant site at Bhopal". All the six coarse samples were separately collected in polythene bags and brought to DRDE, Gwalior. The samples were grinded, homogenized and filtered using 40 mesh sieve and stored in glass bottles at room temperature.
