Joggers running along an urban running path noticed paint running out of a culvert into a nearby creek. local authorities investigated and found that some homeowners had painted the outside of their home and dumped the extra paint down a storm drain. they were fined. what type of water pollution did they cause? a. toxic b. sediment c. nutrient d. bacterial

Option (A)

Explanation:

The paints are generally used to color the walls in the houses and buildings. But they are effective for human health as well as to the environment. It is because they are comprised of various components such as the pigments, solvent, and binder. These pigments are mostly comprised of elements as well as chemicals. Some of them are lead, benzene, chromates, methylene chloride, asbestos, and some others. These are harmful and toxic to the health of the organism as this can cause severe diseases like cancer.
