Answer 1

Answer:

B. Many of these substances, when eaten, cause serious health problems over time.

Explanation:

Electronic wastes are unwanted electrical or electronic material that has been thrown out by the user to be managed by waste managers. Mismanagement of electronic wastes can lead to a serious threat from the heavy metal deposit, this can affect the environment and humans.

During recycling, some of the heavy metal such as lead, cadmium, and Mercury is released to surrounding water bodies also direct disposal of such waste can result to increase of such metals.

As a large amount of heavy metal enters the river, it gets accumulated in the tissues of fishes overtime. Long term consumption of fishes that are affected by heavy metal poisoning can lead to some health-threatening issues such as;

• Liver malfunction

• Renal problems and

• Cardiovascular diseases.

Therefore when fishes are affected by lead poisoning they affect human when eaten over time.
