New Guide for Minimizing Heavy Metal Accumulation in Metalworking Fluids.
1. Scope
This guide will describe the health risks associated with heavy metal accumulation in recirculating metalworking fluids (MWFs). It will address the health risks and waste discharge issues caused by such heavy metal accumulation. The practice will recommend strategies for minimizing heavy metal accumulation in MWFs.Keywords
metal removal fluids, metal forming fluids, heavy metals, metalworking fluids, health and safetyRationale
Long-life recirculating MWFs experience cycles of concentration that cause dissolved heavy metals and other non-volatile, soluble compound to accumulate to potentially toxic levels. This proposed new Practice will review the mechanisms that contribute to this accumulation and recommend means for controlling it.
