Analysis on Chemical Characteristics and Source of Water-Soluble Ions in Atmospheric Particulate Matter in Yulin Grottoes
摘要
Abstract
This experiment takes inhalable particulate matter(PM10)from Yulin Grottoes as the research object(August 2022 to June 2023),focusing on the pollution characteristics of water-soluble ions,and briefly analyzing the sources of pollution.Research has shown that the order of nine water-soluble ion concentrations in PM10 in Yulin Grottoes is SO42-＞Ca2+＞Cl-＞NO3-＞Na+＞K+＞Mg2+＞NH4+＞F-;SO42-,Ca2+,Cl-,NO3-,and Na+ account for 92.8%of the total ion content;the annual average values of Sulfur Oxidation Rate(SOR)and Nitrogen Oxidation Rate(NOR)indicate that SO42-and NO3-in PM10 are mainly secondary conversions.Factor analysis shows that water-soluble ions in PM10 mainly come from saline soil dust,Yulin Grottoes cliff dust,and secondary aerosols.关键词
