Forest filtering is a well-known and efficient method for diminishing atmospheric pollutant (such as SO42- and Cl-) inputs to soil and water; however, the filtering efficiencies of forests vary depending on the regional vegetation and climate. The rainy area of West China has suffered from heavy rainfall and human activity, which has potentially resulted in large amounts of sulfur and chlorine ...
This study was carried out to understand how land use patterns influence surface water quality in Tien Giang Province using remote sensing and statistical approaches. Surface data were collected at 34 locations with the frequency of four times (March, June, September, November) 2019. Water parameters used analysis, including pH, temperature, electrical conductivity (EC), total suspended solids ...
The role of the atmosphere in formation chemical composition and quality water Lake Baikal its tributaries has been increasing recent years. In this regard, studies constituents have an important practical application. 2020 2021, we studied atmospheric aerosol, one indicators air pollution, coastal zone southern basin compared to data from previous were carried out summer on southwestern (Bolsh...
Arsenic is a toxic and carcinogenic contaminant of potential concern. Ettringite [Ca6Al2(SO4)3(OH)12·26H2O] has the ability to incorporate oxyanions as a solid solution with SO42-, which could lower the soluble oxyanion concentrations. Therefore, ettringite containing SO42- and AsO43- has been synthesized. Results indicated that AsO43- could substitute for SO42- inside the channels of ettringit...
in the present study, 45 rainwater samples were collected from february to december 2012 on event basis in east bokaro coal mining environment. physico-chemical and major ionic compositions of rainwater samples as well as water soluble major ion composition were analyzed to employ principle component analysis for source identification. the average ph value was recorded 6.1 and varied from 5.1 t...
Assessment of groundwater quality is important for drinking water, especially rural populations. The aim this study was to assess the human consumption by integrating water index with geographic information system (GIS) eventual interpretation Meknes area quality. Eight wells and two springs were investigated between February 2013 2014. In light analysis results, spatial distribution maps chose...
The levels of dissolved sulfate and methane are crucial indicators in the geochemical analysis of pore water. Compositional analysis of pore water samples obtained from sea trials was conducted using Raman spectroscopy. It was found that the concentration of SO42- in pore water samples decreases as the depth increases, while the expected Raman signal of methane has not been observed. A possible...
The long-term effects of ambient PM2.5 and chemical constituents on childhood pneumonia were still unknown. A cross-sectional study was conducted in 30,315 children the China Children, Homes, Health (CCHH) project, involving 205 preschools six cities China, to investigate lifetime-ever diagnosed pneumonia. Information demographics collected by validated questionnaires. lifetime annual average P...
