Bio monitoring of air pollution around urban and industrial sites
Journal Title: Journal of Research in Biology - Year 2012, Vol 2, Issue 1
Abstract
Plants are the only living organisms which have to suffer a lot from automobiles exhaust pollution and industrial pollution because they remain static at their habitat. Experiments on air and bio monitoring were conducted to evaluate pollution impact on the vegetation along the road in Dindigul town TamilNadu. The plantation along the roads mainly include Azadiracta indica, Delonix elata, Morinda tinctoria, Calotrophis, Thyme rosemary and Cyandan dactylon. For bio monitoring, total chlorophyll, carotenoid, ascorbic acid, protein and total sugar were analyzed to study the impact of air pollutants. It was observed that vegetation at the road side with heavy traffic and industries was much affected by air pollutants. Significant reduction of total chlorophyll, carotenoid, protein and total sugar was observed. These variations can be used as an indicator of air pollution for early diagnosis of stress or as a marker for physiological damage to trees prior to the on set of visible injury symptoms. It is concluded that plants can be used as indicators for urban air pollution, and it is need to protect the road side plants from air pollution
