We carried out an integrated environmental/biological monitoring program to evaluate cancer hazards among metal industry workers exposed to cutting fluids. Several cutting fluids were sampled according to response to a semiquantitative nitrite rapid test in metal factories in central Italy. The nitrite-positive samples were analyzed for nitrite and nitrosodiethanolamine (NDELA) content and muta...

Biological monitoring of occupational hazards was performed in workers using cutting fluids containing N-nitrosodiethanolamine (NDELA). The study involved a group of 25 male subjects from some metal factories in central Italy who used cutting fluids with an NDELA content of > or = 5 mg/l (high-exposure group) and a group of 37 males exposed to cutting fluids with an NDELA content < 5 mg/l (low-...

turning of hardened steels using a single point cutting tool has replaced the cylindrical grinding now as it offers attractive benefits in terms of lower equipment costs, shorter set up time, fewer process setups, higher material removal rate, better surface quality and elimination of cutting fluids compared to cylindrical grinding. in order to obtain desired surface quality by machining, prope...
