This research was conducted to bring out the appropriate level of heavy metal contamination in soil at the site of Buriganga river bank near the Hazaribagh tannery area and the normal agricultural area to evaluate heavy metal contamination in soil due to untreated tannery effluents. AAS flame method was used to determine the concentration of Chromium (Cr), lead (Pb), Cadmium (Cd), Zinc (Zn) in several depths of the soil. Results showed that, the heavy metal concentration in soil at the site of Buriganga river bank in the tannery vicinity and normal agricultural area significantly varies, such as Cr varies (561.71 -31.23) mg/kg, Zn varies (158.23 -73.5), Pb varies (70.58 -24) and Cd varies (2.25 -0.71) mg/kg in the river bank as well as in the normal agricultural area Cr varies ) and Cd varies (1.30 -0.64) mg/kg. The study indicated that heavy metals concentration was found to be significantly higher in river bank soils than in the normal agricultural area. This metal concentration in soil is responsible for the promotion of toxicity in agricultural products. Therefore, the human health and environment are affected by these areas.

“…Chromium, a naturally occurring heavy metal commonly used in many industrial manufacturing processes is responsible for major industrial and environmental pollution. The main chromium industries include metal plating and finishing, leather and textile manufacturing, electro-painting industries which discharge huge quantities of toxic metal ions to the surrounding environment [1][2][3]. Being non-degradable, chromium gets accumulated and persists in nature for a long time and may enter into the food chain causing remarkable health damage.…”

“…These metals, at higher concentration, are toxic and cause detrimental effects on human health (Trichopoulos 2001;Kocasoy and Sahin 2007). Chromium is a carcinogen and it also damages the gastrointestinal, respiratory and immunological systems (USEPA 1989;IARC 1990;Islam et al 2013). Cadmium, even at very small concentrations, is highly poisonous and chronic exposure to this metal can lead to anaemia, insomnia, cardiovascular diseases as well as hypertension (Sharma et al 2006).…”

“…Cadmium, even at very small concentrations, is highly poisonous and chronic exposure to this metal can lead to anaemia, insomnia, cardiovascular diseases as well as hypertension (Sharma et al 2006). Excessive lead exposure increases blood pressure, damages kidney, causes miscarriages and subtle abortions, hinders brain development, and leads to behavioural disruptions (Islam et al 2013). Arsenic causes vascular diseases, hyperpigmentation, lung and skin cancer, hypertension and genotoxicity (Islam et al 2018;Das et al 2004).…”

ignificant amounts of heavy metals in the directly discharged wastewater released from the newly built tannery industrial site inDhaka,Bangladeshare reported. Despite their detrimental impacts on public health and natural ecosystem, no environmental impact study is yet conducted. Therefore, information on safe discharge rates are not available. In this study, the extent of pollution around the industrial site is investigated for four representative trace metals. Temporal and spatial distributions of chromium (Cr), lead (Pb), cadmium (Cd) and arsenic (As) have been predicted using a numerical model with the aim to estimate safe discharge of these metal contaminants. From multiple simulation runs it has been estimated that a discharge of0.026 m3 of wastewater per day can lead to high levels of Cr and Pb accumulation, exceeding the regulatory standard limits, in the study area. Whilst As and Cd concentrations remain below the advised limits in most cases at this rate. However, an order of magnitude reduction in the total discharge rate, i.e.,0.0026 m3 per day, results into the metal accumulation below the recommended guidelines in all cases. Elevated concentration of Pb is found to be limited to the top 0.5 m of the soil as compared to Cr, As and Cd, which exhibit larger spread along the depth of the soil. The relative dominance of the metal contamination follows the sequence: Pb>Cr>As>Cd as sorbed concentration in soil aggregates and Cr>Pb>As>Cd as aqueous concentration in soil porewater. Further investigations that are essential for a comprehensive environmental impact assessment have been highlighted.
