The International Agency for Research on Cancer RC) has classified wood dust as carcinogenic to humans based on demiological and experimental evidence. Exposure to wood dust may use respiratory and dermal symptoms and diseases. The aim of this work was to estimate occupational exposure to inhalable wood dust adopting the formal procedure described by UNI EN 689/97. The exposure of 23 workers in three different working day was measured. In total, 69 personal air samplings were carried out at five wood working factories. Inhalable fraction of airborne dust was collected on 5 microm pore size, 25 mm diameter PVC filters utilizing the IOM samplers. The quantity of the wood dust was determined with gravimetric method. The results show that about 13% of the exposure values exceed the limit of 5 mg/m3 specified by the Italian Law Decree 66/2000 and about 48% of personal exposures are lower then the limit value. Prevention measures, technological solutions and personal protection equipment should be adopted in order to reduce worker's exposure.
国际癌症研究机构(IARC)已根据流行病学和实验证据将木尘归类为对人类致癌物质。接触木尘可能会引发呼吸道和皮肤症状及疾病。这项工作的目的是采用UNI EN 689/97所述的正式程序来估算可吸入木尘的职业暴露量。对23名工人在三个不同工作日的暴露情况进行了测量。总共在五家木材加工厂进行了69次个人空气采样。使用IOM采样器在孔径为5微米、直径为25毫米的PVC滤膜上收集空气中粉尘的可吸入部分。用重量法测定木尘的量。结果表明,约13%的暴露值超过了意大利第66/2000号法律令规定的5毫克/立方米的限值,约48%的个人暴露低于限值。应采取预防措施、技术解决方案和个人防护设备以减少工人的暴露。
