EFFECT OF AUTO-EXHAUST POLLUTION ON ROAD SIDE TRITICUM AESTIVUM AND HORDEUM VULGARE
Shaimaa Abo-Hamad
Abstract
Air pollution is a world wide problem which increases day by day by different human activities. The enormous increase in vehicle numbers running on roads is one of the most important causes of air pollution. This study was carried out to determine the effect of road side automobile pollution on the growth of two economically important crops in Egypt (Triticum aestivum and Hordeum vulgare). It was found that yield parameters, carbohydrate, soluble protein of plant seeds grown on road side were significantly decreased compared with plants away from road side by distance of at least 1 meter. Lead concentration was higher in plant seeds grown on road side and this was reflected on the ionic concentrations of Ca, K, Mg and Fe. Total amino acids content of seeds was highly increased in response to air pollution, so the amino acids profile can be taken as a bioindicator of auto-exhaust air pollution.
