An Assessment of the Impact of Industrialization on Physical Environment and Socio-economic Conditions around the Alipur Industrial Area, Bangladesh

Abstract

Massive industrialization promotes economic growth and causes environmental pollution and degradation. The purpose of this research is to determine the impact of industrialization on the physical environment and socio-economic condition at Alipur industrial areas, Habiganj, Bangladesh, by measuring water, soil, air, sound quality parameters and a random sampling questionnaire survey on socio-economic conditions. Most of the measured physicochemical parameters exceeded the acceptable limit of inland surface water. The pH of the effluent water ranged from 4.83 to 8.58, which was found lower than the standard level for two points. The DO level was within the range of 1.98 to 3.32 mg/L indicating that aquatic life is in danger because of the lower level of DO. BOD, COD, TSS, and TDS ranged from 133 to 255.8 mg/L, 330 to 566 mg/L, 1960 to 2170 mg/L and 4110 to 5500 mg/L, respectively. The concentration of Nitrates (14.63 mg/l), Phosphate (10.33 mg/l), and Copper (5.49 mg/l) in the water samples found more than the inland surface, public sewer STP, and Irrigated land standard.  The concentrations of CO (10.71), NO2 (90.56), and SO2 (104.34) in the air are near the acceptable level, indicating that the air was moderately polluted. The Durbin-Watson statistic is 0.495 from the model summary indicating the research model has a positive auto-correction, and the coefficient of significance is at 0.00, and Test F at 150.345 suggests that the model is suitable. Furthermore, the coefficient of the land area lost due to industrial park construction is found at 0.00, indicating household income increased when people lose land and non-agricultural sectors like building houses, investing in services, traffic systems. On the other hand, it is undeniable that few members whose land is acquired turned unemployed during industrial parks, resulting in the high number of unemployed workers being high and income declines.
