Brominated flame retardants are used in many household products like mattresses and upholstery. Why is there some concern about their use?
- They are highly resistant to degradation in the environment.
- They are able to accumulate in humans and animals.
Select the correct answer using the code given below.
Answer
Both 1 and 2
1. Highly resistant to degradation in the environment — Many brominated flame retardants, especially PBDEs, are persistent organic pollutants; they break down very slowly. Verdict: Correct.
2. Able to accumulate in humans and animals — These chemicals are bioaccumulative and have been detected in human tissues, wildlife, and breast milk. Verdict: Correct.
Since both 1 and 2 are correct, the answer is (c) Both 1 and 2.
