There is some concern regarding the nanoparticles of some chemical elements that are used by the industry in the manufacture of various products. Why?
- They can accumulate in the environment, and contaminate water and soil.
- They can enter food chains.
- They can trigger the production of free radicals.
Select the correct answer using the code given below.
Detailed Explanation:
✅ Statement 1 – Correct: Nanoparticles are extremely small (1-100 nm) and resistant to degradation, allowing them to persist and accumulate in soil and water bodies, contaminating the environment.
✅ Statement 2 – Correct: Due to their microscopic size, nanoparticles can be absorbed by plants and microorganisms, entering the food chain and undergoing biomagnification at higher trophic levels.
✅ Statement 3 – Correct: Certain nanoparticles can induce oxidative stress in cells by triggering the production of reactive oxygen species (ROS) or free radicals, which damage DNA, proteins, and cell membranes, potentially causing inflammation and cancer.
