“…The pH of sediments was measured in 1:2.5 soil to water ratio. The soil/deionized water mixture was stirred with a clean glass rod, and the slurry was allowed to equilibrate for 30 min . The pH values were recorded using a Horiba U-23 instrument with the calibration of pH 4.0, pH 7.0, and pH 9.0 standards.…”

This research was conducted to evaluate the concentration of seven common heavy metals (Cr, Ni, Cu, Zn, As, Cd, and Pb) in cereals and pulses and associated health implications in Bangladesh. USEPA deterministic approaches were followed to assess the carcinogenic risk (CR) and noncarcinogenic risk which was measured by target hazard quotient (THQ) and hazard index (HI). Total THQ values for As and Pb were higher than 1, suggesting that people would experience significant health risks if they ingest As and Pb from cereals and pulses. However, the estimated HI value of 1.7 × 10(1) (>1) elucidates a potential noncarcinogenic risk to the consumers. Also, the estimation showed that the carcinogenic risk of As (5.8 × 10(-3)) and Pb (4.9 × 10(-5)) exceeded the USEPA accepted risk level of 1 × 10(-6). Thus, the carcinogenic risk of As and Pb with nutritional deficiency of essential elements for Bangladeshi people is a matter of concern.

“…The soil organic carbon (SOC) was determined by a solid blowtorch total organic carbon detector (Vario TOC, Frankfurt, Germany) after the removal of inorganic carbon by hydrochloric acid acidification. The soil pH and conductivity (EC) in the supernatant of a 1:2.5 soil–water mixture were measured with a pH meter and a EC meter, respectively (Ahmed et al, 2012). The soil mineral composition was determined by X‐ray diffraction (XRD, D8 Advance, Karlsruhe, Germany) at 40 mA and 40 kV with Cu Kα radiation, which was operated in the range of 3°–85°.…”

Influence of soil evolution on the heavy metal risk in three kinds of intertidal zone of the Pearl River Estuary

et al. 2020

Human activities and the increasing emphasis on coastal protection contribute to the diversity and evolution of intertidal soil. But, less is known about the influence of soil evolution on the heavy metal risk in intertidal zones. In this study, soil samples were collected from three kinds of intertidal zone in the Pearl River Estuary, including bare beach (BB), a spartina growing area (SGA), and a mangrove growing area (MGA), to reveal the influence of key factors on the heavy metal risk. The results showed that the highest concentrations of Cd, Zn, Pb, Cu, Ni, and Cr mainly existed in the surface layer of SGA and MGA and decreased with depth, reaching 3.57, 365.26, 91.24 95.12, 58.47, and 111.35 mg kg−1, respectively. Residual fractions were the main geochemical fractions and increased with depth, while exchangeable fractions showed the opposite trend. Based on the geoaccumulation index, soils were moderately to extremely polluted by Cd and partially to moderately polluted by Zn, Cu, and Ni. Cd had high potential adverse effects (ranging from 25.29 to 45) in MGA according to the risk assessment code. Correlation and principal component analyses indicated that soil organic carbon (SOC), clay, pH, Fe, and Mg were the key factors that affected the heavy metal risk. Linear regression revealed that SOC and clay were positively correlated with the pollution level of heavy metals, while clay and Fe were positively correlated with the ecological risk. Consequently, the variation in properties due to intertidal soil evolution may modulate the risk of heavy metals.

Heavy metal toxicity has proven to be a major threat to human and have health hazard for consuming agricultural foodstuff grown around brick kiln areas. The hazardous effects of heavy metals are very harmful for the human body. Heavy metals get accumulated in the body and food chain, exhibiting a chronic nature. This research was conducted to evaluate the concentration of six common heavy metals (Cr, Ni, Cu, As, Cd, and Pb) in agricultural foodstuff associated health implications in Bangladesh which grown in brick kiln vicinity. The United States Environmental Protection Agency (USEPA) deterministic approaches were employed to determine the potential health risk of heavy metals in foodstuff. Estimated daily intake (EDI), noncarcinogenic risk and carcinogenic risk were assessed to explore human health hazard specially children. Heavy metals concentration for all foodstuffs exceed maximum allowable concentration causing potential health risk to consumer of present study areas. The EDI of Cr, Ni, As, Cd and Pb were found higher than maximum tolerable daily intake (MTDI).Total THQ for all metals were more than 1 explaining consumers would face severe health hazard if they ingest these metals from agricultural foodstuffs. Calculated HI values are higher than 1 cause noncarcinogenic risk to adult and children. Again the estimation described that CR of As (6.10E+00 for adult; 2.60E+00 for children) and Pb (2.60E-01for adult; 2.30E-01 for children) exceeded the USEPA accepted risk level (10 -6 ) clearly revealed that consumption of these foodstuffs definitely poses cancer risks to the Bangladeshi population.
