| Abstract This study focus upon the determination of deposited lead on the surface area of plant leaves spreaded in Mukalla streets, the most crowded traffics. Samples of plant leaves from highway roads were studied as a control. Lead was analyzed spectrophotometrically by using dithiozone method. Determined levels of lead for control samples(50 samples) were in the range 0.0234-0.1032 μg/g dry weight with a mean value of 0.0384 μg/g, in October Q. the range was 0.028-0.115 μg/g dry weight with a mean value of 0.0537 μg/g. In Sharge Q. the range was 0.0237-0.1032 μg/g dry weight with a mean value of 0.0512 μg/g, while in Mukalla Q. the rang was 0.0172-0.1247 μg/g dry weight with a mean value of 0.0532 μg/g . The main source of atmospheric pollution by lead in Mukalla is the waste from exhaust of the petroleum fuel automobile. | ||
