Abstract:

Pollution has arisen as a serious environmental concern to the present world after industrialization of human societies. It has severely affected our air, soil and water sources. Looking to its global, national, regional and local dimensions, it is now imperative to check it at each and every level. In the present study, 8 samples (3 Yamuna water samples, 3 tannery effluent samples and 2 textile effluent samples), were collected from different sites of Yamuna and exit points of textile and tannery Industries. Water and effluent samples were analysed for various physicochemical parameters (pH,

Abstract:

Common effluent treatment plant (CETP) is employed for treatment of tannery effluent. However, the performance of CETP for reducing the genotoxic substances from the raw effluent is not known. In this study, phytotoxic and genotoxic effects of tannery effluents were investigated in mung bean (Vigna radiata (L.) Wilczek). For this purpose, untreated and treated tannery effluents were collected from CETP Unnao (UP), India. Seeds of mung bean were grown in soil irrigated with various concentrations of tannery effluents (0, 25, 50, 75, and 100%) for 15 days. Inhibition of seed germination was 90%

Abstract:

Leather is a material with unique mechanical properties, making it widely used in the production of footwear, clothing, sports articles, and in the field of coverings, such as in the automotive, furniture, marine and aeronautical industries. Leather processing involves three major stages: beamhouse, tanning, and finishing. In each of these stages, characteristic effluents are generated, which typically reach the Wastewater Treatment Plant (WWTP) mixed, for the so called end-of-pipe treatment, consisting of primary and secondary treatment.

Tannery effluents have reutilization potentials and may be harnessed for human welfare. Tannin, the chief component of tannery effluent, increases biological oxygen demand.

Tannins, the chief component of tannery effluents, are degraded by bacteria, yeasts and fungi. Little work has been attempted using blue green algae.

The production of leather involves a lengthy producing chain and has a wider impact on the economy. Large amounts of solid waste are produced during the various phases of leather manufacturing. Due to the release of untreated effluent, the tannery industry is a major environmental polluter and has a high potential to pollute land and water. When leather is produced, more than 250 chemicals are used, and a complex mixture of toxic organic chlorinated phenols, toxic Cr(VI), and other toxic pollutants are released, including formaldehyde resins, pesticide residues, mineral salts, dyes, and solven
