Physico-chemical analysis of the industrial effluents and their impact on the soil microflora

Industrial Effluents entering the water bodies is one of major sources of environmental toxicity. It not only affects the quality of drinking water but also has deleterious impact on the soil microflora and aquatic ecosystems. Soil is the most favourable habitat for a wide range of microorganisms that includes bacteria, fungi, algae, viruses and protozoa. Industries keep on releasing effluents, which is quite toxic whether its sugar mill or fertilizer industries, or chemical treatment given to the fields also cause problems for the survival of the soil micro flora. In the present study we have analyzed the effluents of sugar and textile industry and their deleterious effects on the soil microflora. Analysis of the textile effluents shows that the ph (8.1 – 9.1); TSS (190 – 163); TDS (4354 – 5768), BOD (181 - 306) and COD is (3853 – 4691) whereas in the sugar effluents ph (7.1 – 9.1); TSS (301 - 494); TDS (2560 - 3978), BOD (2225 - 4526) and COD is (10896 - 16843). The values exceed the NEQS and FMENV values. The microbial flora too is affected by it as compared to the control water sample due to the high BOD and COD values.
