相对于水、土壤和生物群等其他介质，污染物可以通过大气尘埃和气溶胶快速和较长距离地迁移;但很少有研究明确评估这一途径的环境影响，使其成为一种基本但研究不足的迁移机制。虽然有许多自然和人为活动会增加环境中的粉尘和气溶胶排放以及污染物水平，但采矿作业在产生的颗粒物数量、全球受影响地区范围以及与排放有关的污染物毒性方面值得注意。在这里，我们审查（一）的环境命运和运输的金属和非金属粉尘和气溶胶从采矿业务，（二）目前的方法来评估污染物浓度和颗粒物排放，以及（三）潜在的健康和环境风险与空气中的污染物从采矿业务。审查评估未来的研究重点的基础上，现有的文献，并建议有一个特别需要测量和了解的生成，命运和运输的空气中的颗粒物从采矿作业，特别是细颗粒部分。更一般地说，我们的研究结果表明，采矿作业在产生污染的大气粉尘和气溶胶以及金属和类金属污染物的运输方面发挥了重要但未得到充分重视的作用，并强调了在这一领域进一步研究的必要性。采矿活动在环境污染物的归宿和迁移方面的作用在未来几十年可能变得越来越重要，因为气候变化和土地使用预计将加剧，这两者都可能大大增加粉尘排放和迁移的可能性。
Contaminants can be transported rapidly and over relatively long distances by atmospheric dust and aerosol relative to other media such as water, soil and biota; yet few studies have explicitly evaluated the environmental implications of this pathway, making it a fundamental but understudied transport mechanism. Although there are numerous natural and anthropogenic activities that can increase dust and aerosol emissions and contaminant levels in the environment, mining operations are notable with respect to the quantity of particulates generated, the global extent of area impacted, and the toxicity of contaminants associated with the emissions. Here we review (i) the environmental fate and transport of metals and metalloids in dust and aerosol from mining operations, (ii) current methodologies used to assess contaminant concentrations and particulate emissions, and (iii) the potential health and environmental risks associated with airborne contaminants from mining operations. The review evaluates future research priorities based on the available literature and suggest that there is a particular need to measure and understand the generation, fate and transport of airborne particulates from mining operations, specifically the finer particle fraction. More generally, our findings suggest that mining operations play an important but underappreciated role in the generation of contaminated atmospheric dust and aerosol and the transport of metal and metalloid contaminants, and highlight the need for further research in this area. The role of mining activities in the fate and transport of environmental contaminants may become increasingly important in the coming decades, as climate change and land use are projected to intensify, both of which can substantially increase the potential for dust emissions and transport.
