What type of pollutant is DDT?

DDT is a persistent organic pollutant (POP). It is made by humans and does not occur naturally in the environment. DDT was used as an insecticide to prevent the spread of disease and to protect crops.

Is DDT a biodegradable pollutant?

DDT, plastics, polythene, bags, insecticides, pesticides, mercury, lead, arsenic, metal articles like aluminium cans, synthetic fibers, glass objects, iron products, and silver foils are non-biodegradable pollutants. Was this answer helpful?

Why is DDT an organic pollutant?

DDT is highly insoluble in water and is soluble in most organic solvents. It is semi-volatile and can be expected to partition into the atmosphere as a result. Its presence is ubiquitous in the environment and residues have even been detected in the Arctic.

Is DDT a water pollutant?

DDT is very insoluble in water and very persistent in the environment, making it a highly polluting hazard.

Whats is DDT?

Dichlorodiphenyltrichloroethane (DDT) is an insecticide used in agriculture. The United States banned the use of DDT in 1972. Some countries outside the United States still use DDT to control of mosquitoes that spread malaria.

What is a persistent organic pollutant examples?

The most commonly encountered POPs are organochlorine pesticides, such as DDT, industrial chemicals, polychlorinated biphenyls (PCB) as well as unintentional by-products of many industrial processes, especially polychlorinated dibenzo-p-dioxins (PCDD) and dibenzofurans (PCDF), commonly known as dioxins.

What are some examples of organic pollutants?

Abstract. Persistent organic pollutants (POPs) are toxic synthetic chemical substances (aldrin, chlordane, dieldrin, endrin, heptachlor, hexachlorocyclohexane, mirex, dichlorodiphenyltrichloroethane, polychlorinated biphenyl, polychlorinated dibenzofurans, etc.) that persist in the environment for a long period of time ...

Is DDT organic or inorganic?

DDT is a persistent organic pollutant that is readily adsorbed to soils and sediments, which can act both as sinks and as long-term sources of exposure affecting organisms.

What are non-biodegradable pollutants?

Non-biodegradable pollutants are those which cannot be decomposed by bacteria e.g., mercury, polythene, aluminium DDT etc.

Is smog a primary or secondary pollutant?

Harmful Secondary Pollutants

Primary pollution is harmful enough, but when it mixes with the atmosphere, it creates damaging secondary pollutants like smog and nitrogen dioxide. These secondary pollutants can affect other areas too by creating acid rain.

What is DDT plastic?

DDT (dichloro-diphenyl-trichloroethane) was developed as the first of the modern synthetic insecticides in the 1940s. It was initially used with great effect to combat malaria, typhus, and the other insect-borne human diseases among both military and civilian populations.

Is DDT an organophosphate?

Dichlorodiphenyltrichloroethane (DDT) is a representative organochlorine insecticide and a known endocrine disruptor. Malathion is an organophosphate insecticide and a next-generation pesticide.

What is DDT quizlet?

dichloro-diphenyl-trichloroethane.

What is DDT biomagnification?

Biomagnification happens when toxic chemicals, like DDT, whose remains in the environment are consumed indirectly by organisms through food. When an organism in the higher food chain consumes the lower organism containing such chemicals, the chemicals can get accumulated in the higher organism.

Which of the following is an inorganic pollutant?

The correct answer is Hydrogen sulphide. Pollutants like carbon dioxide (CO₂), carbon monoxide (CO), sulfur dioxide (SO₂), nitrous oxide (NO), and nitrogen dioxide (NO₂), Hydrogen sulfide (H₂S) are collectively called Inorganic gaseous pollutants.

What is biodegradable pollutant example?

Few examples of biodegradable pollutants are, Wastes produced from humans and animals waste. Plant products, dried leaves, grass, fruits and flowers. Food wastes, wood and other remains from the death of living creatures.

Which of the following best describes why DDT is classified as a persistent organic pollutant?

Which of the following best describes why DDT is classified as a persistent organic pollutant? DDTDDT is very stable, and as much as 50% of the original concentration can remain in the soil 15 years after the initial application.

What are persistent and non persistent pollutants?

The Degradable or called as non-persistent pollutants can be rapidly broken down by natural process. For example domestic sewage, discarded vegetables, Slowly-degradable or persistent pollutants are pollutants that exist in the environment for many years in a stable condition and take decades or longer to degrade.

What are the 5 types of Persistent organic pollutants?

Types of persistent organic pollutants (POPs) include intentionally produced chemicals such as pesticides aldrin, chlordane, DDT (1,1,1-Trichloro-2,2-bis[p-chlorophenyl]-ethane), dieldrin, endrin, heptachlor, mirex, hexachlorobenzene (HCB), and toxaphene as well as industrial chemicals such as polychlorinated biphenyls ...

What are the 12 Persistent organic pollutants?

These were a group of 12 highly persistent and toxic chemicals: aldrin, chlordane, DDT, dieldrin, endrin, heptachlor, hexachlorobenzen, mirex, polychlorinated biphenyls, polychlorinated dibenzo-p-dioxins, polychlorinated dibenzofurans, and toxaphen.

What does DDT cause?

Following exposure to high doses, human symptoms can include vomiting, tremors or shakiness, and seizures. Laboratory animal studies showed effects on the liver and reproduction. DDT is considered a possible human carcinogen.

What are the chemical properties of DDT?

Is DDT an organochlorine?

In the United States (US), the organochlorine insecticide dichlorodiphenyltrichloroethane (DDT) was first used during World War II to combat malaria, typhus, and other diseases among military populations. Widespread use began shortly after in 1945.
