“…Many studies in the recent years have shown, on a worldwide basis, a considerable degree of pollution of roadside soil and vegetation from lead in traffic exhaust emissions and cadmium in tire wear and motor oils (Ademoroti 1986;Eisenreich d al. 1986;Flanagan et al 1980; Krishnayya and Bedi 1986;Maga 1971;Ndiokwere 1984; Page and Bingham 1973 ;Rodriguez-Flores and Rodriguez-Castellon 1982). The most important reason for considering motor vehicles as polluters of agricultural soil and vegetation is that metals, as well as gaseous pollutants, such as oxides of sulphur, nitric oxides, carbon monoxide, unburned hydrocarbons and partial oxidation products (formaldehyde, acetaldehyde, acrolein, etc.…”

Samples oj"&its (grapes, pomegranates, and tomatoes), and vegetables (onions, potatoes, and spinach) were collected directly from randomly selected commercial farms along the Tripoli-Zawiya major road, at the appropriate harvest seasons, during the period of May through November 1988. The objective was to determine the extent of contamination of the crops with toxic heavy metals, lead and cadmium, from trafic emissions. For the purpose of comparison, similar crops were collected, within the sameperiods,from farms in Waddy Al-Rabia, far away from any major road.lhe samples were dry-ashed, and analyzed using flameless Atomic Absorption Spectrophotorneter (AAS) .lhe statistical analyses of the experimental data showed that the major road contributed significantly (P < 0.05) to higher concentrations of lead in aLl the crops examined; and also cadmium in all the crops except in potatoes. Vegetable crops were found to have higher contents of these two metals than the fruits. Substantial amounts of these metals could be removed by washing the samples with triple distilled water.

“…The impact of auto-exhaust emissions on seed germination and seedling growth of roadside trees has been reported by various workers. Krishnaya and Bedi (1986) have reported the toxic effects of automobile exhaust on germination of Cassia tora and C. occidentalis and they also observed improvement in seed germination with increase of 60 m distance from the road. Among different tree species the highest reductions in seed germination were recorded in L. leucocephala as compared to others (Table 4).…”

Effect of auto-exhaust emissions on the seed germination of tree species growing along roadside was studied at four locations viz., National Highway 21-A (Baddi), Baddi-Barotiwala link road, Kalka-Charnia link road and 200m away from road in Kalka-Charnia Link Road (Control) in BBN industrial area of Himachal Pradesh, India. The seed germination in all the tree species under study decreased in sites where seeds were collected from roadside trees as compared to control where seeds were collected 200m away from road in Kalka-Charnia link road. The germination (%) in Leucaena leucocephala was 4.0, 11.5 and 34.0 in seeds collected from National Highway 21-A (Baddi), Baddi-Barotiwala link road and Kalka-Charnia link road, respectively, against 43.0% seed germination in control. In Toona ciliata, the seed germination was 95.0, 97.0 and 96.5% in National Highway 21-A (Baddi), Baddi-Barotiwala link road and Kalka-Charnia link road, respectively, against 99.0% in control. In Dalbergia sissoo the germination ranged between 94.5 and 97.5% in roadside sites against 99.5% germination in control. The germination energy, germination value and germination speed were also found lower in roadside sites as compared to control in all the species. L. leucocephala has been proved more sensitive to auto-exhaust pollutants as compared to T. ciliata and D. sissoo. Among different sites, National Highway 21-A was found most polluted followed by Baddi-Barotiwala link road and Kalka-Charnia link road.

“…Second, the levels of dust lead at 30 m are higher than at 0 m (Table 2). Numerous investigators, including Page and others (1971) and Krishnayya and Bedi (1986), studied the concentrations of lead in roadside dusts and soils (<2 mm) along highways; all reported decreasing lead contents with distance from the roadways, and most of the lead accumulation was found within 15-20 m of the highway. Third, the amount of lead in the surficial soil is lower than the underlying horizons (Table 2).…”

Roadside dusts and soils contamination in Cincinnati, Ohio, USA

/ Roadside dusts and soils were collected from various nonindustrial districts in Cincinnati, Ohio, USA, and analyzed for lead and copper contents. Results showed that the recent lead phase-down action has reduced the level of lead, but the concentrations of both metals are still higher than the background levels for normal soil. Elevated concentrations of copper in heavily traveled highways were noted, suggesting that much of the copper pollutants is probably of automotive origin. The concentration of lead was found to vary with housing age, and higher levels of contamination in the older neighborhoods were observed. This result is probably ascribable to the accumulation of residues from leaded gasoline and lead-based paint in the past and the use of coal fire for space heating in older houses.
