Contaminated fish are unhealthy to eat because they contain large amounts of toxic chemicals, such as
a.
calcium
b.
mercury
c.
potassium
d.
smog

B.mercury

Explanation:

Fish and bivalves concentrate mercury in their organisms, often as methylmercury, an organic compound of mercury that is highly toxic. The investigations carried out have made it possible to determine that marine products can contain diverse concentrations of heavy metals, particularly mercury and contaminants soluble in fats coming from water contamination. Fish species that are long-lived and occupy a high position in the food chain contain higher concentrations of mercury than other species. The presence of mercury in fish can have repercussions on the health of human beings since when consumed fish can produce mercury poisoning, especially of those women who are pregnant or who can get pregnant, mothers who are breastfeeding, and babies.

in contrast, the biological controls are self-sustaining, inexpensive and very effective once established. biological control could be used on thousands of golf course acres, improving their biodiversity and quality as wildlife habitat. in the process, the golf industry will be shown to be leaders in an environmental stewardship program of benefit not only to the lands they manage but also to the watersheds in which they exist.
