What are two chlorinated hydrocarbons?

What are two chlorinated hydrocarbons?

Chlorinated hydrocarbon insecticides are fat soluble. They can last for a long time in the environment and contribute to long-term clinical toxicity. These organochlorine insecticides include aldrin, chlordane, dichlorodiphenyltrichloroethane (DDT), endrin, heptachlor, chlordecone (Kepone), and lindane.

Is DDT a chlorinated hydrocarbon?

Chlorinated Hydrocarbons Perhaps the best known chlorinated hydrocarbon insecticide is DichloroDiphenylTrichloroethane, or DDT. First synthesized in the 1800s, the insecticidal properties of DDT were not discovered until 1939.

What is a chlorinated hydrocarbon insecticides?

Is chlorine a chlorinated hydrocarbon?

What Are Chlorinated Hydrocarbons? Chlorinated hydrocarbons are chemical compounds of chlorine, hydrogen, and carbon atoms only. Many of them form the building blocks of other chemical products such as pharmaceuticals, plastics, and solvents.

Where are chlorinated hydrocarbons found?

Chlorinated hydrocarbons such as perchloroethylene (PCE) and trichloroethylene (TCE) are widely used industrial solvents and degreasing agents that have entered and contaminated the environment (e.g., soil and groundwater) through leakage in storage tanks and irresponsible disposal practices in the past.

What are chlorinated hydrocarbons and organophosphates?

Chlorinated hydrocarbon insecticides and organophosphate compounds are used regularly around poultry houses to control external parasites. Commonly used organochlorine insecticides include chlordane, dieldrin, DDT, heptachlor, and lindane.

What are chlorinated organic compounds?

Chlorinated organic compounds (COCs) otherwise known as organochlorine pesticides (OCPs) is one of the multi-arrays of hydrophobic organic compounds which have been produced in large quantity, and used for the control of weeds, termites, mosquitoes and other insects constituting nuisance in many part of the world for …

Are chlorinated hydrocarbons still used today?

Are chlorinated hydrocarbons banned?

Lindane is used medicinally for the treatment of lice and scabies. Chlorinated hydrocarbons are of major toxicologic concern, and many (eg, DDT [dichloro-diphenyl-trichloroethane] and chlordane) have been banned from commercial use because they persist in the environment and accumulate in biological systems.

Are chlorinated hydrocarbons still used?

Is Chlorpyrifos a chlorinated hydrocarbon?

Chemical Class and Type: Chlorpyrifos is a broad-spectrum, chlorinated organophosphate (OP) insecticide, acaricide and nematicide.

What are examples of chlorinated solvents?

Chlorinated Solvents. Chlorinated solvents are a large family of chemical compounds that contain chlorine, for example, carbon tetrachloride (carbon tet), trichloroethylene (TCE), or methylene chloride.

Is chlorinated hydrocarbons toxic?

Chlorinated hydrocarbons are of major toxicologic concern, and many (eg, DDT [dichloro-diphenyl-trichloroethane] and chlordane) have been banned from commercial use because they persist in the environment and accumulate in biological systems.

Is Roundup A chlorpyrifos?

Like glyphosate, an ingredient in the popular weedkiller Roundup, chlorpyrifos has been used widely. It was first registered in 1965 and helps control pests on a number of high-value crops, including almonds, alfalfa, walnuts, and oranges.

Is acetone chlorinated?

Acetone is organic while bleach is inorganic. The formula of acetone is (CH3)2CO while that of chlorine-based bleach is (NaOCl). Bleach is generally used for whitening fabrics and other surfaces while acetone is used in nail polish removers and paint thinners. As compared to acetone, bleach is more toxic.

Is benzene a chlorinated solvent?

and further chlorinated hydrocarbons such as dichloromethane, carbon tetrachloride ethanol but also terpenes such as d-limonene and even acetic acid ester. Volatile organic compounds used in textile industry include Formaldehyde, Styrene, Toluene, Benzene and others as well as the subgroup of chlorinated solvents.

What are the negatives effects of chlorinated hydrocarbon?

Epidemiological evidence suggests that the increased incidence of a variety of human cancers, such as lymphoma, leukemia and liver and breast cancers, might be attributed to exposure to these agents.

Where do chlorinated hydrocarbons come from?

Because of their wide array of uses, chlorinated hydrocarbons are among the most important industrial organic compounds. Since they are derived from distillates of petroleum fossil fuels, however, the depletion of global oil and coal reserves looms as a concern for the future.

What is the most toxic pesticide?

Paraquat is one of only two pesticides still used in the United States that is either banned or being phased out in the European Union, China and Brazil. It’s the most acutely lethal herbicide still in use today and has resulted in the death of at least 30 people in the United States in the past 30 years.

Why are chlorinated hydrocarbons often dangerous?

The chlorinated hydrocarbons, in particular carbon tetrachloride, are hepatotoxic. Usually, the hepatotoxicity results after the hydrocarbon undergoes phase I metabolism, thereby inducing free radical formation. These free radicals subsequently bond with hepatic macromolecules and ultimately cause lipid peroxidation.

What are the four classification of hydrocarbons?

– Alkanes – Alkenes – Alkynes – Benzene – Toluene, & other alkylbenzenes, eg. Xylenes, Styrene, Phenylacetylene – Polyaromatic hydrocarbons – Fluorene – Allenes, & cumulenes

Why do chlorinated hydrocarbons decompose slowly?

The foremost difference between PHC and chlorinated hydrocarbon (CHC) vapors in the subsurface is that PHCs biodegrade readily under aerobic (oxygenated) environmental conditions, whereas CHCs typically biodegrade much more slowly and under anaerobic conditions (Howard, 1991).

What are chlorinated and fluorinated hydrocarbons?

Alkyl Halides. Freons are very toxic when inhaled in high concentrations or for extended periods.
