Eleven years (2005–2015) of data from long-term monitoring at a Japanese remote background site in Wajima, were analyzed to investigate temporal trends and sources. Water-soluble inorganic ions (WSIIs) for aerosol chemical composition. The total WSIIs concentration was 7.93 ± 3.93 μg/m3, accounting 42.3% TSP mass, ranged 11.4 93.9%. SO42− is the most abundant ion, contributing WSII mass 18.0 79...

background: the municipal solid wastes (msws) are disposed in open dumps, which have no leachate collection and removal system, in the caspian region of iran. leachate readily reaches the nearby water resources such as streams, rivers, lakes, and sea. therefore, understanding the quality and quantity of open dump leachate is vital to the proper treatment of leachate. methods: the leachate sampl...

Sulfate (SO42-) and nitrate (NO3-) are the main secondary inorganic components in atmospheric particulates. It is of great significance to understand formation evolution air pollution process pollution. In this study, samples PM10 were collected Jinhua City eastern China from December 2019 January 2020 June August 2020, also analyzed influence different meteorological conditions gaseous polluta...

9 In some sour reservoirs and tertiary oil recovery blocks, SO42in solution can cause the corrosion 10 and corrosion fatigue of the sucker rods. In this paper, the corrosion behaviors of super-strength 11 sucker rod FG20 (16Mn2SiCrMoVTiA) steel in the well fluid are investigated by electrochemical 12 measurements, and electron probe micro-analyzer (EPMA) analysis. The results show that FG20 ste...

OBJECTIVES To assess cardiopulmonary morbidity associated with daily exposures to PM2.5 in Western Coast of Saudi Arabia. Methods: We monitored 24-h PM2.5 and its constituents including black carbon (BC), particulate sulfate (p-SO42-), nitrate (p-NO3-), ammonium (p-NH4+) and trace elements (TEs) at a site in Rabigh, Saudi Arabia from May to June 2013 with simultaneous collection of hospital dat...

Groundwater contamination in coastal areas has attracted widespread attention. However, studies on the hydrogeochemical characteristics and controlling mechanisms aquifers are still lacking. In this study, 71 sets of groundwater samples were collected during dry wet seasons a city, Shandong Province. Correlation principal component analyses used to identify pollution sources. Meanwhile, Piper d...
