“…For metals analysis, a 0.5‐g sample was digested with 10 ml HNO 3 –HCl mixed solution (5.55% HNO 3 and 16.75% HCl in volume) in a closed Teflon vessel, with an automatic digestion instrument (Politech DigestLinc ST60 Beijing Polytech Instrument Co., Ltd). The digested sample was then transferred into a Teflon beaker, shaken well, allowed to cool for 20 min, diluted to 50 ml with Milli‐Q water, allowed to stand for 2 h, and measured after filtration (Kormoker et al., 2019). Atomic fluorescence spectrometry (AFS‐930, Beijing Jitian Company) was used to determine Hg and As (Ministry of Agriculture of the People's Republic of China, 2008a, 2008b).…”

Human activities have caused toxic metal pollution and ecological risks to agricultural soil. In this study, 291 topsoil samples, collected in the agricultural soil system of Yuzhong, China, were selected to study the toxic metals and metalloids contamination characteristics, source and ecological risk based on geostatistics, pollution index, and ecological risk index. The main distribution of As is adjacent to pasture land and mainly comes from animal husbandry; Pb was observed near a coal mining factory and the Yellow River and was derived from industry and transportation; Cd was similar to Pb and was mainly derived from industry, transportation, and agriculture; Cr was found near a cement plant and was derived from industry and transportation; and Hg was found near an urban area and was mainly from industry and domestic garbage. The ratio of these elements exceeding the soil background value reached 99.9%. Except for the excess amounts of Cd and Hg in some samples, Cr, Hg, and As were mostly below permissible limits. Moreover, the comprehensive potential ecological risk of toxic metals is mainly at medium level and below, whereas the risks of Cd and Hg are higher. Control of Cd and Hg is important to prevent soil pollution. This study explains the current contamination situation, the predominant contaminants and their sources, and provides emphasis and direction for agricultural soil remediation.

“…EC is also considered an essential property of drinking water (Subramani et al 2005). EC is the measure of cations and anions concentrations dissolved in water (Islam et al 2017;Ahmed et al 2019). In the current study, the EC value of the water varied from 345 to 654 μS/cm (mean 535.47 μS/cm) in the summer season, while it varies from 647 to 798 μS/cm (mean 724.0 μS/cm) in the winter season.…”

Louhajang River, Bangladesh, crosses Tangail, which is a densely industrialized and urbanized city. Louhajang River is an essential water source for domestic, irrigation, and urbanization purposes. This study reports the levels of pH, electrical conductivity (EC), and some toxic heavy metals in 40 water samples collected during summer and winter seasons from Louhajang River. The levels were found to be in the ranges of pH 6.22-7.43 and EC 345-798 mS/cm, Cr 0.18-13.2, Ni 0.02-19.04, Cu 0.96-15.92, As 2.18-12.51, Cd 0.02-2.42, and Pb 0.49-15.74 µg/L. The winter season reported higher levels of the examined parameters than the summer season with significant variation (p < 0.05) for all parameters, with the exception of Cd. The metal contents were assessed against local and international standards for drinking, irrigation and aquatic life purposes where different trends were observed. The heavy metal evaluation index (HEI) and the ecological risk index (ERI) reported low to moderate risks. The spatial distribution of metal contents assigned hot spots in some sites along the riverbed, which were attributed to specific manmade sources. The health risk assessment for three population categories, i.e., adult male, adult female, and children, were examined in terms of hazard index (HI) and total cancer risk (TCR) for oral and dermal pathways during both seasons. Cr and Cd recorded HI more than unit in all cases, indicating possible non-cancer risk. TCR values of As for the three examined population categories during both seasons were > 1.0×10-6, indicating possible cancer risk, while that of Pb were < 1.0×10-6. For Ni, about 10-25% of the sampled sites recorded TCR > 1.0×10-6.

Brick kiln exhaust when deposited can hamper the nutritional status of the agricultural soils and crops. To study the impact, soil and associated plant samples were collected from the vicinity of a brick kiln cluster in Chattogram, Bangladesh. The soil contamination was evaluated by heavy metal indices. Agricultural soils close to the brick kiln area were very strongly acid to slightly acid. Organic carbon, total nitrogen and available phosphorus content of the agriculture soils near brick kiln cluster were 0.35% to 1.01%, 0.10 to 0.24% and 2.21 to 13.48 mg kg-1 respectively and the significant different mean value of 0.70%, 0.22% and 14.65 mg kg-1 respectively in the reference soil. The nutritional status of sampling sites was lower than the previously reported data. The nutrition status of the plants was at an optimum level as regular fertilizer application was practiced but showed an irregular pattern along with all the soil parameters and heavy metal indices. The contamination factor (Cd), potential ecological risk index (PER) and geo-accumulation index (Igeo) demonstrated that the agricultural soils in the vicinity of the brick kiln cluster were moderately- to highly-polluted. This indicates the deterioration of soil quality by uncontrolled brick kiln operation.
