考虑到超细颗粒对健康的潜在不利影响，对几种微观环境（可能包括环境空气、室内空气和职业环境）中的纳米颗粒进行有效监测至关重要。事实上，有效和准确的监测是获得一套数据的第一步，这些数据可进一步用于进行风险评估和流行病学研究等后续评估，从而提出诸如遏制措施等良好工作做法，以减少职业接触。本文提出了一种在几种微环境中监测超细颗粒/纳米颗粒的有用方法，使用在线分析仪和采样系统，允许对收集的纳米颗粒进行进一步表征。该方法在论文中提出的三个案例研究中得到了验证，这些案例研究评估了室外大气、烹饪作业和焊接车间中纳米颗粒的监测情况。
: Bearing in mind the potential adverse health effects of ultrafine particles, it is of paramount importance to perform effective monitoring of nanosized particles in several microen-vironments, which may include ambient air, indoor air, and also occupational environments. In fact, effective and accurate monitoring is the first step to obtaining a set of data that could be used further on to perform subsequent evaluations such as risk assessment and epidemiologic studies, thus proposing good working practices such as containment measures in order to reduce occupational exposure. This paper presents a useful methodology for monitoring ultrafine particles/ nanoparticles in several microenvironments, using online analyzers and also sampling systems that allow further characterization on collected nanoparticles. This methodology was validated in three case studies presented in the paper, which assess monitoring of nanosized particles in the outdoor atmosphere, during cooking operations, and in a welding workshop.
