Chlorinated hydrocarbons Assessment of chlorinated hydrocarbons and trace metal contamination of Moroccan marine species book widely used as solvents and raw materials for the synthesis of various useful products, such as cleaning agents, pesticides and poly vinyl chloride (PVC).

These chlorinated hydrocarbons, however, cause serious environmental problems when they were released into the air. Abdelaziz Hraiki has written: 'Assessment of chlorinated hydrocarbons and trace metal contamination of Moroccan marine species' -- subject(s): Risk assessment, Contamination.

The effects of oil field fires in Kuwait following the Gulf War were evaluated through studies that investigated hydrocarbons concentration and trace metals in samples of near shore sediments.

The aim of the study was to determine the content of chlorinated hydrocarbon residues in edible mushrooms from the north-eastern part of Poland. Material consisted of two species of fungi: Xerocomus mushrooms (Xerocomus badius), Boletus mushrooms (Boletus edulis).Cited by: 5.

The main objective of this project was to establish a local environmental monitoring network which uses sediments and bioindicator species to assess trends of selected chlorinated hydrocarbons (e.g.

pesticides and PCBs) and heavy metal contaminants in coastal areas of the Dominican by: The concentration ranges of chlorinated hydrocarbons in marine fish were HCB (– ppb), Lindane (– ppb), Endosulphan (– ppb), DDT (– ppb), Aldrin (– ppb) and PCB (– ppb).

Abstract. Among potentially harmful contaminants certain trace metals (mercury, cadmium, lead, copper, zinc), organochlorines (PCB’s, DDT, HCB, HCHs, toxaphene) and hydrocarbons (polycyclic aromatic hydrocarbons) have received particular interest in ecotoxicology as well as priority and significance in the context of the existing conventions for the prevention of marine by: 3.

The degree of contamination depended on pollutant type, fish species, sampling location, trophic level and their mode of by: Chlorinated Hydrocarbons. Chlorinated hydrocarbon or organochlorine insecticides are classified into three groups: (1) dichlorodiphenylethanes (DDT, dicofol, methoxychlor, and perthane), (2) hexachlorocyclohexanes (benzene hexachloride, chlordane, lindane, mirex, and toxaphene); and (3) chlorinated cyclodienes (aldrin, dieldrin, endrin, endosulfan, and heptachlor).

The first use of the. METHOD —CHLORINATED HYDROCARBONS. Scope and Application. This method covers the determination of certain chlorinated hydrocarbons. The following parameters can be determined by this method: Parameter. Chlorinated Hydrocarbons • TCE (as the most toxic is the risk driver) • Multiple historic uses – metal degreaser/cleaner – dry cleaning – anaesthetic • CHCs do not readily degrade in the environment Role of site contamination consultant • Assessment work to be undertaken in accordance with the NEPM /File Size: 4MB.

Because of persistent tissue residues and chronic toxicity, use of chlorinated hydrocarbon compounds has been drastically curtailed. Only lindane and methoxychlor are approved for use on or around livestock.

Detectable residues of some chlorinated hydrocarbon insecticides, including BHC, heptachlor, heptachlor epoxide, lindane, and oxychlordane, can be found in fatty tissue after acute or.
