Question

All of the following are true EXCEPT

a. Fortunately humans are not susceptible to bioaccumulation of poisons in the environment
b. Certain persistent poisons like DDT affect the health of the top predators in the food chain like eagles and panthers most severely
c. Some persistent chemicals are known to disrupt development, making children most susceptible
d. Polar bears have high levels of persistent organic pollutants in their bodies, compromising their survival
e. Chemicals that act as endocrine disrupters have produce rodents with both male and female reproductive organs"

Answer 1

The statement that humans are not susceptible to bioaccumulation of environmental poisons is false, as humans can bioaccumulate toxic substances like heavy metals and persistent organic pollutants, which can lead to severe health issues.

Step-by-step explanation:

The question is asking which of the statements regarding environmental pollutants and their effects is false. After evaluating the given statements, we can identify that the incorrect statement is:

a. Fortunately humans are not susceptible to bioaccumulation of poisons in the environment

This statement is false because both humans and animals are susceptible to bioaccumulation of persistent organic pollutants (POPs) like DDT, mercury, and lead. These substances are bioaccumulative and toxic, with the potential to cause serious health effects, including damage to the nervous and reproductive systems, as well as increase the risk of cancer.

On the other hand, statements b, c, d, and e all describe real and significant dangers associated with environmental toxins. For example, top predators are indeed severely affected by certain persistent poisons such as DDT, due to biomagnification through food chains. Similarly, polar bears do carry high levels of POPs, affecting their survival.
