Concept explainers
To determine:
Whether the given statement ‘Methylmercury is a toxic industrial pollutant found in highest concentration in small fish’ is true or false.
Introduction:
Methylmercury is a toxic compound which affects the nervous system of humans and cause symptoms like fatigue, memory loss, lack of concentration, etc.
Answer to Problem 1RQ
Solution:
The given statement is False.
Explanation of Solution
Explanation for correct answer:
The given statement is false because Methylmercury is seen in maximum quantity in large marine or ocean fishes. They are in less concentration in small fishes. Some examples of fishes with highest concentration of methylmercury are shark, tilefish, etc. The people eating these fishes suffered from its toxicity which lead to nervous system damage in them.
Methylmercury is a more toxic form of mercury which causes nervous system damage in humans.
