Chlorinated organic compounds, prevalent contaminants found in the geo-environment, pose an ecological risk even at trace concentrations. More volatile chlorinated compounds such as VOCs (volatile organic compounds) have been detected in urban areas and industrial zones because of the use of these compounds as components of industrial solvents and both raw and intermediate synthetic products. C...

A previously described porous organic polymer (NU-POP-1) was evaluated against four representative chemical threats: ammonia, cyanogen chloride, sulfur dioxide, and octane. Ammonia, cyanogen chloride, and sulfur dioxide are examples of toxic industrial chemicals (TICs) spanning the range from highly basic to strong-acid forming substances, while octane is used to assess physical adsorption capa...

A pig slurry treatment strategy must include processes with the aim of reducing volatile organic compound emissions, controlling odours, mineralising nutrients, improving its fertilising proprieties, and recovering energy, when it is possible. In this sense, anaerobic digestion fulfils all this requirements. However, in areas with high animal farming density and a structural nutrient surplus, i...

Office devices can release volatile organic compounds (VOCs) partly generated by toners and inks, as well as particles of paper. The aim of the presented study is to identify indoor emissions of volatile halogenated organic compounds into the office workspace environment. Mixtures of organic pollutants emitted by seven office devices, i.e. printers and copiers, were analyzed by taking samples i...

Gas Chromatography (GC) is a mature analytical technology used predominately for separating and quantifying the components of complex organic chemical mixtures. The addition of mass selective detectors has extended the use of GC to include compound identification. A wide range of columns and sample introduction techniques allow GC to solve most analytical problems for volatile and semi-volatile...

Pollution of aquatic ecosystems due to toxic mixtures is a worldwide problem associated with the increase wastewater discharges that causes problems human health and biodiversity. This study aims evaluate cytotoxic potential water from Atoyac River. Meristems Allium cepa L. were exposed samples River different concentrations for 120 hours. Pearson correlation was used investigate relationship b...
