Determination of Environmental Deposition of Lead (Pb) in Certain Selected Samples in the Industrial Areas of Gazipur District of Bangladesh

Abstract

Hasty industrialization affects the environment in different ways by discharging the large quantity of effluents as dissipate water in the surrounding water bodies, causing the solemn problems to environment. Twenty (n=20) samples of each category were collected from different locations of Gazipur. 3-5 goat of each sample was considered for analytical procedure. The results of analysis of variance of mean Pb-concentration in different samples collected from different locations differed significantly (P<0.05). The detected mean value of lead (Pb) concentration in drinking water (ground water), surface water, industrial waste water and agricultural soil (crop land) was 0.048±0.005mg/L ml/L, 0.428±0.098 ml/L, and 38.859±5.766 ml/L and 79.059±16.261 mg/kg. The mean value of concentrations of lead (Pb) was also detected in poultry tissue and litter samples. The highest level of lead (Pb) concentration was found in bone followed by brain, kidney, liver and muscles. The detected mean value of lead (Pb) in bone, brain, kidney, liver and muscles were 0.082±0.005 mg/kg, 0.073±0.007 mg/kg, 0.071±0.007 mg/kg, 0.052±0.011 mg/kg and 0.038±0.005, respectively. As regards biological samples, the highest natural accumulation of lead (Pb) was found in chicken bone while the lowest concentration (Pb) was detected in muscles. The natural accumulation of Pb was highly and significantly (P<0.001). The poultry litter (0.580±0.059 mg/kg) was also detected significantly (P<0.05) as a major toxic agent in respect of lead (Pb) for environmental degradation due to the use of poultry litter in agricultural soil (crop land) to grow more crops and vegetables.
