“…The factor F1 consisted of NO 3 - , Cl - , Cd, Co, and Ni showed similar results of the Spearman correlation analysis, which were important industrial and agricultural raw materials. The sources of these heavy metals are usually related to industrial and agricultural activities under such a significant correlation [ 26 , 54 ]. The factor F1 mainly reflects the influence of agricultural and industrial activities.…”

“…However, unlike air and dust, most people are exposed to water for a very short time every day, the risk posed by direct contact with the groundwater such as the skin exposure in the shower is generally less than 1% of the total. [ 25 , 26 ]. Therefore, compared with the previous studies, this paper pays more attention to the health risks from drinking.…”

Heavy metals pollution in groundwater and the resulting health risks have always been an environmental research hotspot. However, the available information regarding this topic and associated methods is still limited. This study collected 98 groundwater samples from a typical agricultural area of Songnen Plain in different seasons. The pollution status and sources of ten heavy metals (As, Ba, Cd, Co, Cr (VI), Cu, Fe, Mn, Ni, Pb, and Zn) were then analyzed and compared. In addition, the human health risks assessment (HHRA) model was used to calculate human health risks caused by heavy metals in groundwater. The results revealed that heavy metals were mainly distributed in the northwest of the study area and along the upper reaches of the Lalin river and that the concentrations of heavy metals were higher during the wet season than the dry season. Industrial and agricultural activities and natural leaching are the main sources, and each kind of heavy metal may have different sources. Fe and Mn are the primary pollutants, mainly caused by the native environment and agricultural activities. The exceeding standard rates are 71.74% and 61.54%, respectively based on the Class III of Quality Standard for Groundwater of China (GB/T 14848-2017). The maximum exceeding multiple are 91.45 and 32.05, respectively. The health risks of heavy metals borne by different groups of people were as follows: child > elder > young > adult. Carcinogenic heavy metals contribute to the main risks, and the largest risks sources are Cr and As. Therefore, the government should appropriately restrict the use of pesticides and fertilizers, strictly manage the discharge of enterprises, and control man-made heavy metals from the source. In addition, centralized water supply and treatment facilities shall be established to prevent the harm of native heavy metals.

“…Hazard Index (HI) is the most commonly used method to evaluate the risk of trace elements in groundwater to human health. Because children are the most sensitive to the exposed heavy metals, the analysis in this study focused on the children's HI (Chen et al 2020). There are two main exposure pathways to the contaminants in drinking water: dermal absorption (e.g., bathing)…”

The water resource is highly demanded in the Yangtze River Delta with a developed economy. Long-term exploitation has posed threats of artificial pollution and seawater intrusion to the shallow groundwater. This study aimed to reveal the hydrochemical characteristics and health risks of shallow groundwater in the coastal plain of the Yangtze River Delta. Also, possible factors affecting groundwater quality were discussed. Methods, such as typical hydrochemical tests, water quality assessment and health risk models, were applied to achieve the study targets. The results showed that the shallow groundwater was slightly alkaline, and the average values of total dissolved solids (TDS) and total hardness (TH) were 930.74 mg/L and 436.20 mg/L, respectively. The main hydrochemical types of groundwater were Ca+Mg-HCO3 and Ca/Na-HCO3, accounting for 44.3% and 47.5%, respectively. In addition, As concentration was generally high, with a mean value of 0.0115 mg/L. The principal factors affecting the groundwater components include water-rock interactions (especially silicate), cation exchange, seawater intrusion and human activities. As in the groundwater is strongly influenced by the redox of Fe, Mn, and NO3 -. The results of the groundwater quality evaluation indicated that the shallow groundwater in some regions was unsuitable for drinking and agricultural irrigation.Health risk assessment showed that 44.3% of the water samples had significant health risks, which was attributed to the high As concentration. Therefore, it is urgent to establish long-term As monitoring to maintain sustainable groundwater management and drinking water safety. The results of this study can provide essential data for water resource management and human health protection in the Yangtze River Delta.

“…The trace elements that enter the body via MFHT consumption can be harmful to human health. When essential trace metals accumulate in excessive concentrations in specific tissues or organs of the body, they can be toxic (Prasad 1988 ; Xu et al 2004 ; Horning et al 2015 ; Mohammed Abdul et al 2015 ; Xiao et al 2019 ; Chen et al 2020 ). For example, excessive intake of Mn and Zn can cause sluggish movements, dull expressions, dizziness, vomiting, and diarrhea.…”

Owing to the irreplaceable role of traditional Chinese medicine in the history of human resistance to diseases, medicine food homology teas (MFHTs) have emerged as a widely-consumed daily drink, although they may contain toxic or excessive trace elements. This study aims to determine the total and infused concentrations of nine trace elements (Fe, Mn, Zn, Cd, Cr, Cu, As, Pb, and Ni) in 12 MFHTs collected from 18 provinces in China, to evaluate their potential risks to human health, and to explore the factors affecting the trace element enrichment in traditional MFHTs. The exceedances of Cr (82%) and Ni (100%) in 12 MFHTs were higher than those of Cu (32%), Cd (23%), Pb (12%), and As (10%). The high values of the Nemerow integrated pollution index of dandelions and Flos sophorae (25.96 and 9.06, respectively) indicate severe trace metal pollution. The health risk assessment results showed that As, Cr, and Mn in the 12 types of MFHTs posed high non-carcinogenic risk. Honeysuckle and dandelion teas may be hazardous to human health through trace element exposure when consumed daily. The enrichment of Cr, Fe, Ni, Cu, Zn, Mn, and Pb in MFHTs is influenced by the MFHT type and producing area, whereas As and Cd are mainly controlled by the MFHT type. Environmental factors such as soil background values, rainfall, and temperature also affect the enrichment of trace elements in MFHTs collected from different producing areas.
