Effluents textile production

For Reactive Blue 19 [2580-78-1] (Cl 61200 its reactive form, the vinyl sulfone (5), was found in the effluents of a textile mill and a wastewater treatment plant. The hydrolysis product of the vinyl sulfone was detected only in the effluent of the textile mill (257). 

In Estonia the monitoring of effluents is based on chemical analysis. The list of controlled water quahty parameters depends on the type of industry. Bioassays are not used as a monitoring tool. However, according to HELCOM Recommendations No. 16/5, Requirement for discharging of waste water from the chemical industry, and No. 16/10, Reduction of discharges and emission from production of textiles, the toxicity effect of discharges into water bodies should be determined by (at least) two toxicity tests, which could be chosen out of the following four toxicity tests [203] ... 

Production processes used in the pharmaceutical/fine chemical, cosmetic, textile, rubber, and other industries result in wastewaters containing significant levels of aliphatic solvents. It has been reported that of the 1000 tons per year of EC-defined toxic wastes generated in Ireland, organic solvents contribute 66% of the waste [27]. A survey of the constituents of pharmaceutical wastewater in Ireland has reported that aliphatic solvents contribute a significant proportion of the BOD/COD content of pharmaceutical effluents. Organic solvents are flammable, malodorous, and potentially toxic to aquatic organisms and thus require complete elimination by wastewater treatment systems.
