Environmental Pollution
Why is there a great concern about the ‘microbeads’ that are released into environment?
A.They are considered harmful to marine ecosystems.
C.They are small enough to be absorbed by crop plants in irrigated fields.
D.They are often found to be used as food adulterants.
B.They are considered to cause skin cancer in children.
Correct Answer: Option A
Microbeads are tiny, manufactured solid plastic particles, less than one millimeter in size. They're commonly made from polyethylene, but can also be made from other petrochemical plastics like polypropylene and polystyrene.
They are found in exfoliating personal care products, toothpastes, and biomedical research.
The primary concern is that microbeads cause plastic particle water pollution and are a significant environmental hazard to aquatic animals in both freshwater and ocean ecosystems.
Statement a is correct. Statements b, c, and d are incorrect.
