Abstract

An Annular Denuder System (ADS) was used to study sampling errors of total PM₁₀ and soluble ionic species concentrations determined by the high volume PM₁₀ (HVPM₁₀) sampler. Experimental results show that in the HVPM₁₀ sampler, more alkaline glass fiber filters collect more sulfate and nitrate but less ammonium ion than quartz filters. However, total PM₁₀ concentrations do not seem to depend on the types of filters. Artifact sulfate concentrations in glass fiber filters of the HVPM₁₀ sampler are found to exceed those predicted by the Coutant's model. It is suggested that artifact sulfate and nitrate not only occur within filters but also in particle deposits. Chloride ion concentrations in the filters of the HVPM₁₀ sampler are underestimated significantly due to evaporative loss of ammonium chloride.
