many chemicals released by industries are harmful to human health and well being.
industrial chemicals often result in increased dissolved oxygen in local bodies of water.
discharge of industrial waste into water supplies can lead to communities needing to use different water sources.
release of industrial chemicals into surrounding bodies of water alters ph and contributes to ocean acidification.
chemicals, like pfas, harm aquatic organisms like fish and alligators.

Explanation:

• Many chemicals released by industries are harmful to human health and well - being. For example, heavy metals like mercury can cause neurological damage.
• Discharge of industrial waste into water supplies can lead to communities needing to use different water sources. If a river is contaminated, a town relying on it for drinking water may have to switch to wells or other water sources.
• Release of industrial chemicals into surrounding bodies of water alters pH and contributes to ocean acidification. Industrial emissions of sulfur and nitrogen oxides can form acids in water, lowering pH.
• Chemicals, like PFAs (per - and polyfluoroalkyl substances), harm aquatic organisms like fish and alligators. PFAs can accumulate in their bodies and affect their reproductive and immune systems.

On the other hand, industrial chemicals do not increase dissolved oxygen in local bodies of water. Instead, they often cause eutrophication (excessive growth of algae due to nutrient pollution) which can deplete oxygen as the algae decompose.

Answer:

Many chemicals released by industries are harmful to human health and well being.

Discharge of industrial waste into water supplies can lead to communities needing to use different water sources.

Release of industrial chemicals into surrounding bodies of water alters pH and contributes to ocean acidification.

Chemicals, like PFAs, harm aquatic organisms like fish and alligators.
