Pollution & waste Easy

Why is there a great concern about the ‘microbeads’ that are released into environment?

Answer & explanation

Answer: (a) They are considered harmful to marine ecosystems.

Microbeads are tiny plastic beads put into cleansers and toothpastes as exfoliants; they slip through water filters, end up in oceans and lakes, and threaten aquatic life.

  • ✓ (a) Microbeads are a type of microplastic. They pass easily through water treatment systems into the sea, where marine animals can swallow them and toxins can collect on them, so they are a threat to marine ecosystems.
  • ✗ (b) Microbeads are rinsed off the skin and the worry about them is environmental pollution; skin cancer in children is not the reason for the concern.
  • ✗ (c) Plastic beads are not taken up into crop plants through their roots; this is not the reason for concern.
  • ✗ (d) Microbeads are used in personal care products, not as food additives or adulterants.

Remember · Microbeads are tiny plastic exfoliant beads in cosmetics and toothpaste that escape water treatment and pollute oceans, harming aquatic life.
