Determinants of Metals Exposure to Metalworking Fluid Among Metalworkers in Taiwan

Abstract

Metalworking fluids (MWFs) aerosols are known to have carcinogenic potential to humans that monitoring of MWFs is necessary to reduce risks. This study summarizes biological monitoring and occupational hygiene findings from a survey of metalworkers exposed to heavy metals in a socket manufacturing plant. Manganese, nickel, iron, copper, chromium, and zinc were selected for target metals. Air samples were collected and postshift urines were obtained from the thread cutting workers and punch press machine operators. There were positive correlations between the airborne concentrations of Cr, Mn, as well as Zn and the corresponding levels of urine for the exposed groups. Therefore, the integration of biological and environmental monitoring is feasible for Cr, Mn, and Zn. The results indicated significant correlations between the levels of Cu, Cr, Fe, as well as Zn from the air and sump MWFs at thread cutting and punch press sites.

Does the presence of microplastics influence the acute toxicity of chromium(VI) to early juveniles of the common goby (Pomatoschistus microps)? A study with juveniles from two wild estuarine populations

“…Chromium is an ubiquitous environmental contaminant that is toxic to the biota (Ahmed et al, 2013;Domingues et al, 2010;Mishra and Mohanty, 2012;Sadeghi et al, 2014) and humans (Wu and Liu, 2014) at ecologically relevant concentrations. It may be accumulated in different tissues (Fatima et al, 2014), and some of its species (e.g.…”

The role of bio-based cutting fluids for sustainable manufacturing and machining processes: A holistic review

“…According to reports, approximately 80% of occupational diseases among operators can be attributed to skin contact with cutting fluids [50]. Constituents in cutting fluids like nitrates and amines [51], hetero-cyclic and poly aromatic hydrocarbons [52], [53], biocides [54] are potential carcinogenic agents, and sulfur, chlorine, and phosphorus cause respiratory problems [55], chlorinated paraffin [56], aromatic hydrocarbons, etc. cause diseases.…”
