tracking and determining the amount and types of urban sewage that is being releasing to the environment is important in planning for wastewater treatment systems and water quality control. in this research, in four stations of anzali lagoon, (by means of a gas chromatograph device with mass detector spectrometer) wastewater pollution has been measured and evaluated with molecular indicator lin...

A relatively simple shake-flask system for determining CO2 evolution was developed to assess the ultimate biodegradability by soil and sewage micro-organisms of chemicals which enter the environment. Linear alkylbenzene sulfonates (LAS) were used as model compounds to evaluate the method and were found to undergo substantial biodegradation in this dilute system. At the 30 mg/liter test concentr...

With “defossilisation” at the core of many sustainability goals within industry, exploration new synthesis routes to chemicals has never been more vital. As part their Clean Futures initiative, Unilever Home Care published Carbon Rainbow, a scheme which categorizes chemical sources into different “colors,” depending on derivation. One Rainbow is phase out non-renewable “black” carbon from suppl...

Pharmaceuticals and personal care products (PPCPs) include over-the-counter prescription drugs, veterinary fragrances, cosmetics. PPCPs have been detected in aquatic environments at low concentrations are emerging as contaminants of concern. primarily released into via untreated sewage, wastewater treatment plants, landfill leachate can affect life through persistence, bioaccumulation, toxicity...
