| 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. |
