What animal has the most DDT in their bodies?

Worms, grasses, algae, and fish accumulate DDT. Apex predators, such as eagles, had high amounts of DDT in their bodies, accumulated from the fish and small mammals they prey on.

What contains the most DDT?

Animal and fatty foods contain the highest levels of DDT and PCBs because they are stored in fat and increase in concentration as they move up the food chain. Even though it was banned in 1972, vegetables, meat, fish, and dairy products contain DDT.

Which of the following is most likely to possess maximum amount of DDT in body?

Among the given animals, sea gull which is a fish eating bird and is present at higher trophic level, will have high levels of DDT depositon in its body.

How much DDT is in a minnow?

But the animals that ate the zooplankton, minnows, concentrated it even more, and the DDT in their bodies measured 0.5 ppm.

Is DDT biodegradable?

DDT is harm to all biota of the planet as it is non-biodegradable, and tends to become more concentrated as it moves up the food chain. It is a fat-soluble chemical, and accumulates in the fat deposits of the body.

Where is the concentration of DDT the highest?

DDT accumulates in all tissues but the highest levels are in adipose tissue.

Why does DDT build up in animal tissue?

It accumulates in body tissues because it is not very soluble in water so cannot be excreted. The concentration of DDT in producers is very low, but increases greatly at higher levels in the food chain.

Where does DDT accumulate in the body of organisms?

When an animal consumes food having DDT residue, the DDT accumulates in the tissue of the animal by a process called bioaccumulation. The higher an animal is on the food chain (e.g. tertiary consumer such as seals), the greater the concentration of DDT in their body as a result of a process called biomagnification.

What is DDT full form?

Dichlorodiphenyltrichloroethane (DDT) is an insecticide used in agriculture. The United States banned the use of DDT in 1972.

Which among the following organisms is likely to have maximum concentration of DDT in its body and why frog Peacock grasshopper snake grass?

Which of the following belonging to a food chain is likely to have maximum concentration ofharmful chemicals in its body ? Peacock, Frog, Snake, Grass hopper. Peacock will have maximum concentration of harmful chemicals in its body because it occupies highest tropic level.

Which organisms will contain the highest concentration of chemicals?

Answer: This is biomagnification, and it means that higher-level predators-fish, birds, and marine mammals-build up greater and more dangerous amounts of toxic materials than animals lower on the food chain.

How much DDT is harmful?

DDT is slightly to moderately acutely toxic to mammals, including humans, when ingested. See box on Laboratory Testing. The acute oral LD50 (rat) is 113 to 800 milligrams per kilogram of body weight or mg/kg (6).

What is the lethal concentration of DDT?

It has been reported that 500 mg/kg is the lethal oral dose [Windholz 1983]. [Note: An oral dose of 500 mg/kg is equivalent to a 70-kg worker being exposed to about 23,000 mg/m³ for 30 minutes, assuming a breathing rate of 50 liters per minute and 100% absorption.]

How much DDT is in a marsh plant?

Wind blows some of the pesticide onto the marsh plants. Each plant receives 1 unit of DDT.
