Which of the following is NOT a pesticide banned by the EPA?

Aldicarb is not a pesticide that is currently banned by the Environmental Protection Agency (EPA), which is why it is the correct choice in this instance. Aldicarb has had usage restrictions and guidelines to ensure safety, but it has not received an outright ban like the other options listed.

Heptachlor, Dieldrin, and Mirex have all been banned due to their potential harmful effects on human health and the environment, including their toxicity and persistence in the environment. These substances have been recognized for their ability to accumulate in the food chain and pose significant risks, leading to their prohibition to protect public health and ecological systems.

In contrast, while Aldicarb is regulated and subject to strict controls, it remains on the market under certain conditions, showcasing that not all pesticides face the same level of restriction or ban based on their safety assessments. Thus, Aldicarb’s status sets it apart from the other three listed pesticides.
