The document details the significant environmental impacts of textile effluent, which is chemical waste discharged from textile manufacturing processes. It highlights the detrimental effects on water quality, soil fertility, human health, and aquatic life, with specific emphasis on the toxicity of certain chemicals and how they disrupt ecosystems. Overall, textile effluent is identified as a major pollutant that severely affects both the environment and public health.

Source of Textile Effluent Impact of Textile Effluent on Environment Impact of Textile Effluent on Water Impact of Textile Effluent on soil Impact of Textile Effluent on Human body Impact of Textile Effluent on Fishes and sea life Impact of Textile Effluent on ambient Environment. Overview.
- 3. What is Effluent? Effluent is the stream of excess chemical liquor from an industry after using in original operation.
- 4. Source of Textile Effluent Textile industry employed various process such as sizing, desizing scouring, bleaching, dyeing, printing, finishing etc. After using original operation large amount of excess liquor discharge to drain. In a practical estimate, it has been found that 45% material in preparatory processing, 33% in dyeing and 22% are re-processed in finishing Preparatory… Dyeing… Re-processed…
- 5. Impact of Textile Effluent on Environment Textile effluent considered to be the most polluting element emitted from the textile industry. It affects the environment very badly. The effluent becomes the source of pollution of environment. It pollutes the surface and subsurface water, soil, human bodies, fishes and sea life.
- 6. Impact of Textile Effluent on Water Effluent Mixed with water Reduce Dissolved oxygen Increase hardness of water Enhance metal corrosion Causes Diseases and discomfort Increase or reduce pH as a result: Corrosion of pipe lines and equipment's. Destruction of aquatic life.

- 8. Impact of Textile Effluent on soil Disturb the fertility of soil. Dyes absorb more light so interrupt the photosynthesis activity. Affects plant growth. Heavy metal may store into fruit.
- 9. Impact of Textile Effluent on Human body Some reactive group and toxic chemical are present with Effluent that causes various kinds of diseases and dis comfort such as: 1. Carcinogenic (Benzene) 2. Mutagenic (Benzene) 3. Affected central nervous system (Benzene) 4. Eye and respiratory problem ( Sulphate ) 5. Suppression of hematological system. (Lead)

- 11. Impact of textile effluent on fishes and sea life Highly toxic benzidine based disperse dyes cause toxicity to fishes Dyes chemicals absorb sun light so that plant in water fail to do photosynthesis. Heavy metal complex dyes suffer the gills of fishes.
- 12. Impact of Textile Effluent on ambient environment Disturb the COD and BOD percentage. Increase acidic and basic toxicity.
