Which of the following can cause nervous system damages and cancers?a.Detergent wastesb.Hydrocarbon wastesc.Acidsd.Mercury and lead

The substances that can cause nervous system damages and cancers among the options provided are mercury and lead. These heavy metals are known to be neurotoxic and carcinogenic.

Here's a step-by-step explanation:

1. Detergent wastes: While they can be harmful to the environment and can cause issues like water pollution, they are not typically associated with causing nervous system damage or cancer.

2. Hydrocarbon wastes: These can be harmful and can contribute to conditions like respiratory problems and skin irritation. Some hydrocarbons are indeed carcinogenic, but they are not known for causing nervous system damage.

3. Acids: Depending on the type and concentration, acids can cause a range of health problems, including skin burns and respiratory issues when inhaled. However, they are not typically associated with nervous system damage or cancer.

4. Mercury and lead: Both of these are heavy metals that are known to be harmful to human health. Mercury can cause damage to the nervous system, particularly in developing fetuses and young children. Lead is also neurotoxic, particularly to children, and can cause a variety of other health problems, including cancer. Therefore, the answer is d. Mercury and lead.
