Abstract
Mushrooms are very sensitive to environmental pollution but no scientific study has been conducted so far to evaluate the effect of air pollution on their growth. The objective of this study was to check the impact of fire smoke caused by burning of solid waste (house-hold and hospital waste) on cultivation and nutrition of mushrooms. Total yield, moisture content, dry matter, ash, proteins, fats, carbohydrates, crude fiber of Pleurotus (Flabellatus) Djamor (R-22) commonly known as Oyster mushroom were estimated. The Oyster mushroom was exposed for 20, 40, 60 Min/day to smoke caused by burning of two types of house hold waste and hospital waste in different treatment rooms. Smoke damaged mushrooms soft tissue thus total yield, was reduced to almost half, moisture content and carbohydrates were also significantly reduced. The smoke from hospital waste burning had more harmful effects as compare to smoke from house hold waste burning. However ash, dry matter, protein, and crude fiber were not affected by smoke air pollution.
