Chlorophyll, the green pigment responsible for photosynthesis, is a vital indicator of plant health. Environmental pollution can significantly impact chlorophyll content, affecting plant growth and productivity. This study aimed to estimate and compare the chlorophyll content in grape (Vitis vinifera) and guava (Psidium guajava) plants grown in polluted and non-polluted areas. Leaf samples from both plant species were collected from polluted (industrial and urban) and non-polluted (rural and forest) sites. Chlorophyll content was estimated using spectrophotometry and expressed as mg/g fresh weight. The results revealed significant differences in chlorophyll content between polluted and non-polluted plants of both species. Grape plants from polluted areas showed a decrease in chlorophyll content compared to those from non-polluted areas. Similarly, guava plants from polluted areas exhibited a reduction in chlorophyll content. These findings suggest that environmental pollution can adversely affect chlorophyll content, potentially impacting plant growth and productivity. This study contributes to our understanding of the effects of pollution on plant health and highlights the need for sustainable environmental practices.
