Abstract:
Bangladesh is a low lying area covered country with a huge number of populations.
Most of the population depends upon the agricultural land and cultivation of soil.
But with rapid industrialization, land especially nearside of Dhaka are going too
covered with industries. As expected task, industries are polluting the surrounding
environment with their discharge. The study was carried out to find out the impact
of the Industrial discharge on surrounding environment and agricultural
productivity. During the study a total number of 40 soil samples were collected from
different target location (Tannery, pharmaceuticals, textile, dyeing, food and
beverage Industry prone area) of Ashulia, Savar, Amin Bazar, Dhamsona union of
Savar upazila. Later, Different parameter like pH, P, Fe, Mn, Cd, Cr, As, Pb, DO
were analyzed from the collected sample. The mean value of pH, P, Fe, Mn, Pb, As
in the soil sample of target area in Ashulia was 6.88, 28.27mg/kg, 122.42 mg/kg,
55.56 mg/kg, 27.88 mg/kg, 5.03 mg/kg. In savar it was 7.01, 25.98 mg/kg, 85.67
mg/kg, 44.96 mg/kg, 30.3 mg/kg, 5.39 mg/kg. In Amin Bazar it was 5.94, 24.75
mg/kg, 88.4 mg/kg, 52.62 mg/kg, 38.06 mg/kg and 5.80 mg/kg. In Dhamsona it was
6.90, 25.24 mg/kg, 94.04 mg/kg, 46.21 mg/kg, 30.67 mg/kg, 5.23 mg/kg. Soil of
Amin Bazar was more acidic (5.94 pH) and soil of savar (pH 7.01) and Dhamsona
(pH 6.98) union, It was almost in neutral in condition. Mean P was higher in
Ashulia soil (28.24 mg/kg). Pb (38.06 mg/kg) and As (5.81 mg/kg) was higher in
Amin Bazar soil. Industrial waste must not be discharged to any of the open field,
River, Canal or any other water bodies before recycling. Therefore, Industrial
waste is a great concern to ecosystem and environment. It destroys the ecosystem
function, environment balance and health hazards. Further study should be carried
out to carry out multiple variables related to waste and metal discharge to
investigate the crisis so that clear and deeper information of impact may found.
