Title: Effect of vehicle generated dust particles on the normal plants
Authors: Kulshreshta, Kamla
Issue Date: Jun-2011
Publisher: NISCAIR-CSIR, India
Abstract: The increasing vehicular population (about 26.5 million today) has completely changed the socio-economic scenario of urban India. While burning the mixture of oil petrol, the vehicles especially two-wheelers with two stroke engines, produce blue coloured exhaust, which is reported toxic. The exhaust fumes carry small inert dust particles and also a wide variety of pollutants like benzene, Co, Pb, Ocs, NOx, SO2 and suspended particulate matters with some metal contents as Cd, Cu, Zn etc. The plants are proven to be effective in capture of particulates and other toxic gases from urban air and thus help in improving the urban air quality. Three plants were selected for this study, viz, Nyctanthes arbor-tristis Linn., Quisqualis indica Linn. and Terminalia arjuna Roxb. Wt & Arn. The plants growing in the heavy traffic density areas showed a significant modification in their leaf surface characters like, the insignificant epicuticular wax, increased frequency of epidermal cells, stomata and trichomes, clogged and slightly risen stomata etc. in comparison to control. These changes may be considered as indicators of environmental stress and the plants can be recommended to grow in the high traffic density areas, for the early detection of automobile generated particulate pollution and subsequently to get suitable remedial steps for the remuneration.
