MCQ
Which of the following are causes of industrial pollution?
- AAsbestos.
- BOils.
- CNitrates & Phosphates.
- ✓All of above.
✓
Answer
Correct option: D.
All of above.
Asbestos : This pollutant has cancer $-$ causing properties.
When inhaled, it can cause illnesses such as asbestosis and some types of cancer.
Nitrates Phosphates : These are found in fertilizers, and are often washed from the soils to nearby water bodies. They can cause eutrophication, which can be very problematic to marine environments.
Oils : Oils form a thick layer on the water surface because they do not dissolve in water. This can stop marine plants receiving enough light for photosynthesis.
