Methods for Measuring Atmospheric Acidic Particles and Gases

摘要: This chapter presents an overview of methods to measure atmospheric acidic particles and gases. The main formation mechanisms physico-chemical properties inorganic organic aerosols are discussed first. second part is focused on the measuring these pollutants, with special emphasis spent shortcomings using filters, advantages disadvantages diffusion denuders, use conventional impactors obtain size distribution in atmosphere. final includes results from field studies conducted northern United States, presenting typical levels ambient discussion their spatial temporal concentration variations urban rural areas.
