Given below are two statements. In the light of the above statements, choose the correct answer from the options given below.
Statement I:Bioconcentration in humans can occur due to the consumption of fish.
Statement II:Bioconcentration is the tendency of hazardous substances to accumulate in human tissues.
ABoth Statement I and Statement II are true
BBoth Statement I and Statement II are false
CStatement I is true but Statement II is false ✓ Correct
DStatement I is false but Statement II is true
Correct answer: (C) Statement I is true but Statement II is false
Explanation
Eating contaminated fish can indeed raise the level of toxins in human tissue, so Statement 1 is true.
Toxins concentrated in fish pass up the food chain to the people who consume them.
Statement 2 is false because that build-up of substances within body tissues is properly termed bioaccumulation.
Bioconcentration refers to uptake taken directly from the surrounding water, not through diet.
Fat-soluble and persistent chemicals are the ones most prone to such accumulation.
Mercury in predatory fish is a well-known example of this hazard.
