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.

The bioconcentration value for TCE and aniline in fish is the same at 1.06mg TCE (or aniline) per kg fish, respectively. Fish is only exposed to these contaminants in its environment. About 54g of fish is consumed in 350days/yr for 30years. Assume bioavailability value of 1. The potency factor for TCE is 1.1 × 10$# kg.day/mg and reference dose is 1.00 × 10$% mg/kg.day. Whereas the potency factor for aniline is 5.7 × 10$" kg.day/mg and reference dose (based on drinking water) is 1.60 × 10$& ??/L. Unlike aniline, TCE is not a carcinogenic compound. There are 70yrs in a lifetime and 365day/yr. - Using chronic daily intake calculation, determine the non-cancer risk (number of people in one million) for the above case.arrow_forward
