Aim. To assess the non-carcinogenic health risks associated with elevated concentrations of Fe and Mn in drinking water. Water samples were collected from decentralized sources (wells, boreholes) western Tyumen region, where an iron-manganese biogeochemical anomaly has been identified. Methods. Quantitative analysis Monte Carlo simulations applied to account for natural factors influencing metal solubility. The model parameters included Fe, concentrations, bioavailability Results. exceeded...
The Poyang Lake basin is one of the main agricultural regions in China with dense population. As a result, groundwater research area exposed to anthropogenic influence. This article considers distinctive features chemical composition. A special attention paid pollutants area. composition was found have resulted from complex natural and factors.
The Beck mine, located in the Republic of Karelia, Russia, is an abandoned mining site with significant potential for environmental contamination due to presence pollutants its waste rocks. In this study, we investigated chemical composition mine waters and rocks developed a theoretical model understand waterrock interactions release pollutants. Water samples collected from various locations on property were analyzed showed low concentrations total dissolved solids pH values ranging 6.42...
Various natural and anthropogenic factors affect the formation of groundwater chemical composition geochemical conditions in agricultural areas. However, it is often difficult to evaluate role individual these processes. The article focused on research alteration redox shallow Poyang Lake basin under influence activity with help thermodynamic modelling. modelling field observations demonstrate that reducing result from joint effects factors, organic or NH4–fertiliser usage, proper...
Abstract During the last several decades, wetlands are losing their ecological functions due to increasing anthropogenic loads. One of these is ability bind elements forming geochemical barriers. The research aimed study conditions natural and flooded paddy fields (artificial wetlands) in Ganjiang River basin trace approach was based on a comprehensive analysis water aqueous extracts from bottom sediments soils, including chemical mineral composition. samples were collected November 2019,...
Research of shallow groundwater in the Poyang Lake catchment should be considered as one priority targets this region, due to fact that is formed under influence complex factors, including both natural and anthropogenic, also it related water. Shallow area fresh. High concentrations NO3,Cl−, SO2−4 K+ rarely, Na+ are not typical subtropical humid climate. Within investigated territory could divided into two types – relatively pure groundwater, primarily effect factors having a high content...
The research of trace element behaviour and size fractionation is significant to understand the processes in water-rock system. Moreover, aqueous speciation elements strongly related their distribution toxicity. In this research, are investigated natural water (the surface shallow groundwater) Ganjiang River Xiushui basins. Trace concentrations were measured by ICP-MS. authors estimated between suspended forms (>0.45μm) dissolved fractions, which included truly (1 kDa) colloidal particles...
Актуальность. Проблема охраны и использования болот является весьма актуальной во всем мире, в том числе Западной Сибири, на территории которой добывается значительная часть углеводородного сырья Российской Федерации, что сопровождается изменением окружающей среды, болотных экосистем. В свою очередь, это определяет необходимость разработки методологии технологий природоохранных мероприятий болотах, подвергающихся антропогенному воздействию. рамках такой требуется достоверная оценка изменений...
Abandoned mines are sources of potentially toxic chemical elements, although the development these objects was completed. The Lupikko I mine area (Karelia Republic, Russia) is an excellent example such technogenic objects. It one largest in Pitkäranta area, which abandoned more than hundred years ago. dump rocks here characterized by significant mineral diversity. Disseminated ore mineralization study contains heavy metals, enter natural waters due to oxidative dissolution sulfides. Dump and...
The article is focused on the identification of evaporation and other natural processes which affect isotopic composition shallow groundwater in Poyang Lake basin, such as water-rock interaction mixing surface water. For this purpose dual isotope approach (δD–H2O δ18O–H2O) was used. samples were collected from domestic wells around Lake. value δD obtained for ranges -21.5 to -42.6∘/∘∘. δ18O varies -3.5 -7.1∘/∘∘. It found that catchment meteoric origin. influence negligible observed mainly...
The Poyang Lake basin in the Jiangxi province of China has been exposed to nitrate pollution caused by irrigation practices, leading high groundwater concentration. Eight samples were collected from shallow wells for hydrochemical, bacterial diversity, and community structure analysis November 2017. Shallow groundwaters are weakly acid an oxidizing state, with EC ranging 87.6 279.5 µS/cm TDS varying between 53 344 mg/L averaging 164 mg/L. NO 3 -N form is dominant nitrogen species...
Актуальность исследования обусловлена необходимостью учета разнообразия форм миграцииприродных радионуклидов при смене геохимических условий, а также прогнозированиирадиоэкологического статуса гидроэкосистем. На территории Семипалатинского испытательного полигона миграция естественных в водных системах слабо изучена, расчет миграции урана и тория обстановок будет информативен для понимания широкого спектра трансурановых радионуклидов. Цель: определить формы природных водах зависимости от...
