The results demonstrate that As concentration is mainly found in shallow tubewells (14–49 m deep), which is the main source of drinking water in the region in deep tubewells (>49 m deep), have arsenic concentration < 50 μg/L. The analytical results by field test kits (FTK) revealed...
The focus of this study is on the rural areas of Sindh using ground water as major source of drinking water. In Pakistan groundwater arsenic concentration has reached up to 1100 渭g/L compared with WHO limits of 10渭g/L internationally and 50渭g/L for Pakistan. In the province of Sindh...
Chronic exposure to high levels of arsenic in drinking water can have wide-ranging health effects and is a global health concern. The domestic well population of the western Great Basin (WGB) is at increased risk of exposure to arsenic due to the hydrolo
Arsenic In GroundwaterThe main focus of Arsenic in Groundwater: Poisoning and Risk Assessment is to explore the untold stories of groundwater arsenic in view of its poisonous nature for human health, social implications, exposure and risk assessmentHassan...
解析:细节题;题目中的arsenic可以作为定位词,在原文的第一段中我们看到“Odorless,tasteless,colorless and easily soluble in water or wine,arsenic has long been a feared poison”这样的表述,在4个选项中,A选项所说的“smell”和原文的“odorless”冲突,B选项和D选项则分别和“tasteless”和“colorless”冲突,...
This thesis focuses Arsenic(As) distribution and occurrence in groundwater of Yangtze River Delta economic region, East China. 2019 groundwater samples were collected to analyze 26 chemical compositions, including As. The Principal Component Analysis(PCA) was used to find out As source in groundwate...
Many Chinese lakes have been plagued by eutrophication of water and outbreaks of blue-green algae in recent years. At the same time, many lakes have seen increasing arsenic accumulation in sediments. Researchers from the Institute of Urban Environment under the Chinese Academy of Sciences have analy...
These sites were mainly affected by point source pollution of arsenic, which were derived from sewage and industrial waste water. While the influence of run off was not significant. The content of arsenic ranged from 2.72 to 71.5 mg·kg-1 in the surface sediment of the PRD, with the ...
Water samples from a number of lakes and estuaries, mostly in California, showed measurable concentrations of methylated arsenic (equivalent to 1-59% of total As) with the exception of one highly alkaline lake. Neither depleted phosphate concentrations nor high dissolved salts correlated with the app...
"People in many areas are completely unaware of the risk because their groundwater wells have never been screened for arsenic," the study said. Arsenic is one of the most common inorganic contaminants found in drinking water worldwide.
