Environmental Impact Due To The Contamination Of Bellary Nalla
Abstract
Environmental Impact Due To The Contamination Of Bellary Nalla Due to Globalization fresh water for irrigation is major issue. Hence use of sewage and industrial discharges for irrigation purposes become alternative. The study deals in determining the characteristics of sewage and its effects on soil and crops.
The sewage sample collection was done on every 15 days interval. Sewage samples were initially analyzed for pH, Iron, Zinc, Chromium, Nickel, and Lead, which were within permissible limits. Further Heavy metal analysis was carried out for Soil and Crops. Iron contamination was more in soil whereas Nickel contamination was more in crop.
Conclusion
- As per CPCB standards the recommended pH values of wastewater for land irrigation ranges 5.5 – 9. The pH for all the four wastewater samples lie between 6.93- 7.16.
- The heavy metals (Fe, Zn, Cr, Ni, Pb) of wastewater sample are within the permissible limits.
- The heavy metal analysis showed that Iron and Zinc exceeded the standards of Department of Agriculture and Co- Operation Ministry of Agriculture Government of India.
