Nano- and micro-particles concentrations in working area air at galvanic production: pilot research

Electrochemical processes that involve making protective coats at contemporary galvanic productions are widely spread in various industries. As chemically active solutions and heavy metals are usually applied in galvanic production, it can be ranked among hazardous ones. Our research goal was to examine morphometric parameters of nano- and micro-particles that were detected in working area air at enterprises where galvanic baths and electrochemical processes were applied. To perform a complex examination of particle-size distribution and concentration of a galvanic aerosol (GA) in working area air, we applied a combined procedure that included: 1) measuring qualitative structure of particulate matter (mg/m3) according to ISO 21501-4 in order to determine concentrations of РМ0.3, PM0.5, PM1, PM3, PM5, and PM10 with a portable laser meter; 2) measuring mass concentrations of PM10 according to the European Standard for determining particulate matter EN 12341:2014; 3) measuring particle-size structure of particulate matter via deposition with laser granulometry...
