Question

Ques:- Acid precipitation kills the fish by release of:
(A) Mercury
(B) Lead
(C) Aluminium
(D)Anticoagulants

(Explanation please)​

Answer 1

HELLO THERE

CORRECT ANSWER IS OPTION OPTION D.

Acid rain results when sulfur dioxide (SO2) and nitrogen oxides (NOX) are emitted into the atmosphere and transported by wind and air currents. The SO2 and NOX react with water, oxygen and other chemicals to form sulfuric and nitric acids.

Answer 2

(C) Aluminium

because Al+2 burns the gills of the fish and accumulates in their organs, causing much damage. So, although many fish may be able to tolerate a pH of approximately 5.9, this acid level is high enough to release Al+2 from the soils to kill the fish. This effect is further augmented by spring acid shock.

As acid rain flows through soils in a watershed, aluminum is released from soils into the lakes and streams located in that watershed
