Direct and potential risk assessment of exposure to volatile organic compounds for primary receptor associated with solvent consumption.

摘要: Abstract Rapid development of industrial production has stimulated the growth consumption raw and auxiliary materials including organic paints, among which volatile compounds (VOCs) are proved harmful to population who inhale polluted air based on epidemiologic studies. Therefore, new types environment-friendly paints were developed replace solvent-based (SBPs). Nevertheless, containing VOCs failed SBPs entirely due certain disadvantages. Hence, five kinds employed in simulation experiments assess health risk primary receptor three water-based (WBPs) two SBPs. Conclusions showed that mean TVOC concentration breathing zone ranged from 9.5 13.6 mg/m3 3.4 × 103 1.4 × 104 mg/m3 for WBPs SBPs, respectively. Assessments non-cancer concluded nearly one third quantified exceeded corresponding thresholds WBPs, maximum value was 101.33; reached 50760.20, twenty-two reference limits. The calculation cancer values seventeen higher than acceptable limit amongst 1,2-dibromoethane had 1.27 × 10−2 3.24 × 10−2 WBPs; all limit, 82.61% distributed a scope larger 1 × 10−3. Additionally, removal efficiency 60% considered with personal protective equipment, subsequent results confirmed its inability lowering resulted hazardous VOCs. calculated potential could be applied estimate total both secondary consumed materials. finding suggested improve exposure condition reduce direct significantly receptor, although they might dissatisfy limit.
