|Title:||Impact of Industrial Effluents on Soil Health and Agriculture-Indian Experience: Part II-Tannery and Textile Industrial Effluents|
|Abstract:||A huge amount of effluents generated from tanning and textile industries is being discharged on land or into water courses. These effluents are characterized by high BOD, COD, Na and total dissolved solids. These effluents also contain several major primary and secondary plant nutrients (N, P, K, S, Mg, Ca, etc.) as well as micronutrients and heavy metals. Addition of tannery effluents is reported to cause deflocculation of soil particles and increase in the N, P and K levels of soils. Similarly, deleterious effects, such as increase in pH, sodicity and EC in soils due to the use of textile effluents are reported. However, it is pointed out that the adverse effects of these effluents get progressively reduced with dilution of effluents. But database is not adequate to indicate the effect of long-term use of these effluents on soil health. The impact of the use of these effluents on various crops, trees and shrubs as well as water bodies is discussed. Salinisation and alkalisation of ground water due to application of these effluents are also reported. The physicochemical characteristics of these effluents do not permit its disposal directly into inland water or on land for irrigation, hence, several methods of treating these effluents for safe disposal are discussed.|
