The groundwater in Gaobeidian city is used for drinking, irrigation, industrial production, and other purposes. With the rapid development of the economy and urbanization, groundwater quality has been seriously affected. The main purposes of this paper are to evaluate the groundwater quality in the study area on the basis of understanding the hydrochemical characteristics of the study area and assess the possible health risks of groundwater to children and adults. In this paper, the entropy weight method was used to determine the weight of each evaluation parameter, and on this basis, groundwater quality evaluation was carried out, and the spatial distribution map of groundwater quality was drawn according to the evaluation results. The results show that the weight values of the five parameters of NO2–, Fe, As, Cr6+, and NO2–N are more than 0.1 among the total of fifteen parameters, and the concentration of these five parameters can be considered as the main influencing parameters of groundwater quality. The calculation results of the entropy weighted water quality index (EWQI) show that all the groundwater quality in the study area is class 1 water, which is Excellent Water. However, the EWQI value is the highest in the southwest of the study area, showing a trend of deterioration of groundwater water quality. Since all groundwater samples were evaluated as “excellent water,” it was speculated that the natural environment had more influence on groundwater chemical characteristics than human factors. The study found that 7.407% and 55.556% of the water samples posed a noncarcinogenic health risk to adults and children, respectively. The main responsible parameters for noncarcinogenic risk are F−, NO2−, NO3−, and Cr6+. The carcinogenic risk for adults ranged from 0 to 6.91E-04, with a mean of 1.00E-04. The carcinogenic risk for children ranged from 0 to 1.03E-03, with a mean of 1.55E-04. These toxic elements are mainly from industries. Therefore, the deterioration of groundwater quality can be prevented by strengthening the sewage management of various industries.

A longevity area in Xinjiang, China and an adjacent non-longevity area both have similar climatic and hydrogeological conditions, and the residents of the two control groups have similar ethnic composition, diets and lifestyles. This study investigated if differences in groundwater quality between the longevity area and the non-longevity area are associated with the health of residents in the two control groups. In order to quantitatively describe the groundwater quality of the two control groups and its influence on human health, the Fuzzy Comprehensive Evaluation Method (FCEM) was used to compare and assess the overall water environment of the two control groups. Furthermore, the human health risk of groundwater for the two control groups was assessed using the Health Risk Assessment Model recommended by the U.S. Environmental Protection Agency (USEPA). Results showed that the overall water environment categories for the longevity area and non-longevity area are moderate quality (grade III) and very poor quality (grade V), respectively. The main health risk in the longevity area water environment is the non-carcinogenic risk (HQLLV) caused by Cl−. The main health risks in the non-longevity area water environment are the non-carcinogenic risk (HQCA) caused by Cl− and the carcinogenic risk (RiskCA) caused by As. The total health risk (HRall) caused by over-standard inorganic pollutants in the water environment of the non-longevity area is 3.49 times higher than that of the longevity area. In addition, the study showed that the water environment pollution downstream of the Keriya River is conjunctively caused by agricultural activities and domestic sewage. The overall water environment of the longevity area is more conducive to the health-longevity of residents than the non-longevity area.

Groundwater is one of the main sources for water supply for domestic use, irrigation, aquaculture and industry in Mekong Delta. With rapidly increasing in human population, groundwater becomes more important for social and economic activities. This study evaluated the quality of groundwater using data from the eight monitoring wells over the period of 2009 - 2016. Human health risk was assessed for the population consuming groundwater contaminated with arsenic. The findings indicated that groundwater wells in An Giang province were contaminated with microorganisms. The total dissolved solids (TDS) and hardness in Phu Tan (PT) and Cho Moi (CM) wells were significant higher than the national technical regulations on groundwater quality (QCVN 09-MT:2015/BTNMT). In addition, groundwater wells in some small islands of An Giang were seriously contaminated with organic matters and arsenic. The mean arsenic concentration was up to 0.55 ± 1.21 mg/L. Estimation of carcinogenic risk for human population showed that the cancer risks ranged from medium (8.66 x 10-4) to high (8.26 x 10-2) for both children and adults. Alternative water supply sources should be offered for the population at risk. Besides, regular health check is essential for local people in the arsenic contaminated groundwater. Nước ngầm là một trong những nguồn cung cấp nước chính cho sinh hoạt, tưới tiêu, nuôi trồng thủy sản và công nghiệp ở Đồng bằng sông Cửu Long. Cùng với sự gia tăng dân số, nước ngầm ngày càng đóng vai trò quan trọng hơn trong các hoạt động phát triển kinh tế - xã hội. Nghiên cứu đã tiến hành đánh giá diễn biến chất lượng nước ngầm thông qua số liệu của tám giếng quan trắc trong giai đoạn từ năm 2009 – 2016. Kết hợp với đánh giá rủi ro sức khỏe của người dân khi sử dụng nước ngầm chứa arsenic. Kết quả nghiên cứu cho thấy các giếng nước ngầm ở tỉnh An Giang đã bị nhiễm vi sinh. Tổng chất rắn hòa tan (TDS) và độ cứng ở trạm Phú Tân và Chợ Mới phân tích được cao hơn quy chuẩn cho phép (QCVN 09-MT:2015/BTNMT). Các giếng nước ngầm ở một số khu vực cù lao của tỉnh An Giang đã bị ô nhiễm hữu cơ và arsenic nghiêm trọng. Nồng độ arsenic trong nước ngầm có thể dao động lên đến 0.55 ± 1.21 mg/L. Rủi ro ung thư ở hai đối tượng người lớn và trẻ em khi sử dụng nước ngầm nhiễm arsenic dao động từ trung bình (8 người trong 1.000 người) tới cao (8 người trong 100 người). Cung cấp nguồn nước thay thế là giải pháp khả thi để giảm rủi ro sức khỏe cho con người trong trường hợp này. Ngoài ra, người dân địa phương cần được khám sức khỏe thường xuyên để kịp thời phát hiện và sớm điều trị bệnh.

Abstract The present study was conducted to appraise the suitability and human health risk of groundwater in a rapid urbanization area of North China. Groundwater samples were collected from phreatic and confined aquifers throughout the study area during pre- and post-monsoon seasons. Results show groundwater, regardless the depth, is slightly alkaline in nature and relatively fresh with the total dissolved solids within 600 mg/L. The hydrochemical facies of phreatic and confined groundwater are dominantly HCO3-Ca·Mg, followed by HCO3-Na. Groundwater in the study area, regardless the depth, is suitable for irrigation with almost no salinity and sodium hazards if proper drainage measures are undertaken. The entropy weight water quality index evaluating results show all phreatic and confined groundwater is suitable for drinking purposes. The overall potential non-carcinogenic risk posed by nitrogen (NO3-N, NH4-N) and heavy metals (As, Zn, Fe, Mn) through drinking water ingestion exists in the southwestern area and a small local area in the central study area, and is higher for children. Special attention should be paid to the arsenic because its hazard quotient was very high in some local areas. This study will benefit the protection and utilization of groundwater in near-suburb areas around the world.

This study assessed the mineralogical and geochemical characteristics of geophagic clays sold in some markets in Cameroon to ascertain their provenance, contamination status and human health risk. To achieve this, 40 samples from 13 markets in Cameroon were purchased and analysed using X-ray diffractometry, X-ray fluorescence and laser ablation inductively coupled plasma mass spectrometry for their mineralogy and geochemistry, respectively. The geophagic clays were dominantly made up of kaolinite and quartz. Their chemistry was dominated by SiO2, Al2O3 and LOI with means of 48.76 wt%, 32.12 wt% and 13.93 wt%, respectively. The major, trace and rare earth elements data showed that these geophagic clays were predominantly derived from felsic rocks. The contamination assessment indicated no enrichment of metals from anthropogenic sources, except for Zn in samples from Acacia, Madagascar and Mfoudi markets. The index of geo-accumulation indicated no contamination to moderate contamination of the clays. The non-carcinogenic index values for Fe, Co, Cr, Cu, Ni, Pb and Zn were generally less than 1, suggesting no non-carcinogenic risk exposure to children and adults consuming the geophagic clays from these metals. The carcinogenic risk index (TCR) for Ni and Cr were above 10−6, which implies that children and adults are vulnerable to minimal carcinogenic health risk. The TCR values from Ni posed the highest risk, especially to children consuming clays from some markets.
