Abstract

The accurate measurement of ultrafine and submicron sized airborne particles is a challenging task. Since several studies have linked exposures to airborne ultrafine particles to elevated human health risks, the need to assess the concentrations of particles in the workplace that are below one micron in diameter is imperative. Several techniques for directly monitoring micro and nanoparticles are available and others are being tested for their merit. Condensation Nuclei Counters (CNCs), portable condensation particle counters, differential mobility analysers, electron microscopy and other novel approaches to measuring micro and nanoparticles have been employed in investigations. The purpose of this paper is to elucidate the results from three studies involving the measurement of airborne particles with a laser particle counter and condensation nuclei counter. The three environments include: a gambling casino, a Shielded Metal Arc Welding (SMAW) operation and a general manufacturing facility with welding, cutting and grinding operations being performed.

使用便携式颗粒测量装置来表征在各种环境中产生的空气中颗粒

精确测量超细和亚微米大小的空气颗粒是一项具有挑战性的任务。由于几项研究已将接触空气中的超细颗粒与人类健康风险增加联系起来，因此有必要评估工作场所中直径小于1微米的颗粒的浓度。有几种直接监测微粒子和纳米粒子的技术是可用的，其他技术也正在测试它们的优点。缩合核计数器(CNCs)、便携式缩合粒子计数器、差分迁移率分析仪、电子显微镜和其他测量微粒子和纳米粒子的新方法已被用于研究。本文阐述了用激光粒子计数器和冷凝核计数器测量空气中粒子的三个研究结果。这三种环境包括:赌场，保护金属弧焊(SMAW)操作和一般制造设施，进行焊接，切割和研磨操作。
