What is the water solubility of DDT?

What is the water solubility of DDT?


Melting point 108.5 °C (227.3 °F; 381.6 K)
Boiling point 260 °C (500 °F; 533 K) (decomposes)
Solubility in water 25 μg/L (25 °C)

Does DDT have high water solubility?

DDT is highly fat soluble (dissolves in fat easily), but is poorly soluble in water. Due to its ‘fat-loving’ nature it tends to accumulate in the fatty tissues of insects, wildlife, and people. DDT is stored and biomagnifies in fatty tissues, but produces no known toxic effects while it is stored (2).

Is bifenthrin an organophosphate?

The amount of organophosphate insecticides used in urban areas in California significantly decreased from 2000 to 2006, but the use of bifenthrin, cyfluthrin, and permethrin dramatically increased (TDC Environmental, 2008).

What happens if you drink DDT?

Eating food with large amounts (grams) of DDT over a short time would most likely affect the nervous system. People who swallowed large amounts of DDT became excitable and had tremors and seizures. They also experienced sweating, headache, nausea, vomiting, and dizziness.

Can DDT be found in soil?

Chemical Abstract Service (CAS) nomenclature are used to identify DDT as well as the metabolites/environmental degradation products, DDD and DDE, which are found in soil. CAS nomenclature is given in Appendix 17 for the isomeric forms of DDT, DDD, and DDE which are likely to be found.

What are insecticides mode of action?

Mode of action of the major chemical classes of insecticides involves mainly three target sites in the nervous system: acetylcholinesterase, an enzyme of critical importance in the transmission of nerve impulse (organophosphorus and carbamates), voltage-gated sodium channels across the nerve membrane (pyrethoids and …

Does bifenthrin need to be watered in?

Bifenthrin products usually come in a liquid concentrate which will need to be mixed with water in a pump sprayer. It could also come in granule form and would have to be applied using a granular spreader or a special container that it is packaged in.

How long does bifenthrin last on plants?

Chemical properties Bifenthrin is poorly soluble in water and often remains in soil. Its residual half-life in soil is between 7 days and 8 months, depending on the soil type, with a low mobility in most soil types. Bifenthrin has the longest known residual time in soil of insecticides currently on the market.

How long does DDT stay in your system?

DDT is very insoluble in water and very persistent in the environment, making it a highly polluting hazard. It’s half life has been reported to be between 2 and 15 years.
