PRELIMINARY HEALTH RISK ASSESSMENT OF OCCUPATIONAL EXPOSURE TO NANOPARTICLES IN ELECTRONIC WASTE PROCESSING

Popis výsledku v původním jazyce

Engineered nanomaterials (ENMs) are applied in a wide range of products worldwide. The use of ENM results in a generation of increasing amounts of waste containing nanomaterials. Wastes of electronic and electrical equipment (e-waste) are one of the main waste streams recycled in municipal and industrial waste. There are limited studies that assess the potential exposure to nanomaterials during the recycling processes. The main way how is e-waste prepared for the following recycling is the reduction of its size. The aim of the study was to carry out the preliminary risk assessment of nanomaterials generating within e-waste processing. Occupational exposure was measured in a worker's breathing zone at the recycling site by Condensation Particle Counter (CPC 3007). Workplace air samples were collected on glass microscope slides with Nano-ID Select Wide Range Aerosol Sampler (NANO-ID Select 005) and analysed by Scanning Electron Microscopy (SEM) and Energy Dispersive X-Ray Spectroscopy (EDS). The qualitative risk assessment has been carried out in CB Tool v 2.0. The highest concentrations of nanoparticles were detected for the following elements: chromium, copper, zinc, and tin. The mean concentration of nano- and ultrafine particles (range of 10 - 1000 nm) was 65792 particles/cm3 for all particles. The level of risk obtained from CB tool was equal to RL2, and RL3. Local exhaust ventilation was proposed, based on the assessed risk level, to ensure occupational health and safety. This field study has been conducted as a case study for the subsequent detailed risk assessment and management.
