Which of the following has been banned by the EPA for commercial use?

Dursban, which is a trade name for chlorpyrifos, has been banned by the Environmental Protection Agency (EPA) for commercial use due to its potential harmful effects on human health and the environment. This pesticide has been associated with various issues, including neurodevelopmental harm in children and adverse effects on wildlife. The ban reflects a growing recognition of the need to prioritize safety and reduce exposure to toxic substances, particularly those that can impact vulnerable populations.

In contrast, while Diazinon has faced restrictions and was previously phased out for residential use, it has not been entirely banned from commercial applications in all contexts. Bromethalin is a rodenticide and has not been banned but is regulated. Malathion remains in use for specific applications, though it is subject to restrictions. The decision to ban chlorpyrifos illustrates the EPA's commitment to safeguarding public health by removing particularly hazardous substances from the market.
