Question

for reduction of fungal growth – – may be added in the paint
1 . calcium chloride
2. hydrogen peroxide
3. 8 hydroquinone and pentachlorophenol
4. polyvinyl chloride​

Answer 1

Answer:

Option 3. 8-hydroxyquinoline and pentachlorophenol

Explanation:

• Fungi are responsible for several health-related problems like acute toxicity, hypersensitivity, invasive mycoses and respiratory problems. Fungal contamination is known to cause pollution in building materials. Such contamination often contributes to poor air quality.

• Fungicides are added to paint to substantially reduce or eliminate fungal contamination.

• While PVC or polyvinyl chloride is used as flexing floor materials, calcium carbonate is used to avoid fluid contamination.

• 1% of 8-hydroxyquinoline and pentachlorophenol etc. are added to the paint for the reduction of fungal growth.

Hence for reduction of fungal growth option 3. 8-hydroxyquinoline and pentachlorophenol may be added to the paint.
