Answer: Option C
Solution
Answer: Option C
Solution:
The air pollutants react with lead-based paints, causing decolouration in H2S.Lead is added to paint to accelerate drying, increase durability, maintain a fresh appearance, and resist moisture that causes corrosion. It is one of the main health and environmental hazards associated with paint.
The paint's lead carbonate reacts with hydrogen sulfide in the air and with acids, which often come from fingerprints.
