- ... Background, aim, and scope Chlorinated volatile organic compounds (CVOCs), widely used in industry as solvents and chemical intermediates in the production of synthetic resins, plastics, and pharmaceuticals, are highly toxic to the environment and public health. Various studies reported that Fenton's oxidation could degrade a variety of chlorinated VOCs in aqueous solutions. In acidic conditions, ...

- ... Nearly 20years of industrial scale metal mining operations in Tibet have caused an impact on the region's surface water quality. However, no information with respect to the pollution has been provided to the public. The aim of this work was to evaluate the chemical quality of the stream water and to assess the present and future potential risks of acid mine drainage to the regional and downstream ...

- ... BACKGROUND: At concentrations higher than 1 mg L⁻¹, 4‐chlorophenol (4‐CP) is very toxic to living organisms, and if ingested beyond the permitted concentration it causes health disorders such as cancer and mutation. This laboratory study investigates treatment of contaminated water laden with 4‐CP using coconut shell charcoal (CSC) waste. Batch studies were conducted to study the effects of dose, ...
