黄、渤海大气气溶胶中磷浓度及溶解度的分布特征
Distribution Characteristics of Phosphorus Concentration and Solubility in Atmospheric Aerosols in the Yellow Sea and the Bohai Sea—the Influence of Air Mass Sources and Atmospheric Acidification Processes
摘要
Abstract
Aiming to clarify the critical supporting role of soluble phosphorus(P)in marine atmospher-ic aerosol deposition on the growth of phytoplankton in surface seawater,this study focuses on elucida-ting the spatiotemporal distribution characteristics of aerosol P concentration and solubility in the Yellow Sea and Bohai Sea,in this study,53 atmospheric total suspended particulate(TSP)samples col-lected during five shared cruises in the Yellow Sea and the Bohai Sea during 2013-2018 were used to ana-lyze the concentrations of total P(TP)and dissolved P(DP),and to investigate the characteristics of the spatial and temporal distributions of the P concentration and solubility in the aerosol,as well as the effects of the source of the air mass and the atmospheric acidification process.The results show that the atmospheric aerosol concentrations of TP in the Yellow Sea and the Bohai Sea range from 1.5 to 135.2 ng/m3,the concentrations of DP range from 1.3 to 39.9 ng/m3,and the solubility of P ranges from 12.5%to 88.9%.P concentration and solubility showed significant spatial and temporal distribu-tions.TP concentration showed the characteristics of spring>autumn>summer,DP showed the charac-teristics of spring and autumn were basically equivalent and both significantly higher than summer,while P solubility was summer>autumn>spring.The spatial distribution shows that the atmospheric TP and DP concentrations in the Bohai Sea are higher than those in the Yellow Sea,but the P solubility is lower than that in the Yellow Sea.The source of air masses and atmospheric acidification are impor-tant factors for this spatial and temporal distribution.The TP concentration is the highest in aerosols from northern continental sources and under the influence of sand and dust(NCS-DS),while the DP concentration is higher in aerosols under the influence of northern continental sources(both sand and dust and non-sand NCS-NDS)than that under the influence of marine sources(MS)and southern conti-nental sources(SCS),and the P solubility is MS>SCS>NCS-NDS>NCS-DS.Atmospheric acidifica-tion effects can increase P solubility in aerosols by 10%~27%.关键词
