“…Lead values then decrease at the farthest sampling sites. This is in contrast to the findings of other researchers who demonstrated that lead values decay logarithmically from maximum values closest to the highway (Chow, 1970;Motto et al, 1970;Wheeler and Rolfe, 1979;Muskett and Jones, 1980;Agrawal et al, 1980;Culbard et al, 1988).…”

“…Previous research has shown that lead levels decrease rapidly with distance from the road edge (Motto et al, 1970;Solomon and Hartford, 1976;Wheeler and Rolfe, 1979;Agrawal et al, 1980;Muskett and Jones, 1980;Burguera and Burguera, 1988;Culbard et al, 1988). In this study, exponential sampling intervals were utilised in an attempt to determine if this method can provide a better model of the relationship between soil lead levels and distance from the highway without log transformation of the distance scale.…”

In order to assess the amount and distribution of lead pollution in soils adjacent to a major interstate highway serving the city of Tampa, Florida, a total of 224 samples were collected from 32 transects perpendicular to the roadway. The lead content was measured using atomic absorption spectrophotometry. The highest levels of lead were found at distances of 81, 243, and 729 cm from the road. The results show that there is a weak negative correlation between soil lead and the distance from the roadside, as well as with traffic density. The weakness of the relationship is a result of confounding variables such as turbulence and other microclimatic factors, downslope movement of soils overtime, and human action such as construction and highway landscaping. Nevertheless, over one-third of the samples collected in the study area contain more than 500 μg g(-1) lead, levels considered to be hazardous by the United States Centers for Disease Control and the Environmental Protection Agency.

“…It is produced from the combustion of leaded fuel, especially diesel and petrol, combustion of coal, incineration of wastes and fertiliser manufacture (Noller et al 1981;Nriagu 1988;Melgarejo et al 1986;Agrawal et al 1980;Folio et al 1982;Pirrone et al 1996;Van Grieken et al 1982). The average concentration of Lead in TSP measured in this work is 0.157 μg m −3 .…”

“…Lead is related to combustion of leaded fuels, smelter processes and other industries. It affects the nervous system, the haeme group syntheses and the vascular system with children being worst affected (Nriagu 1988;Barrat 1990;Melgarejo et al 1986;Stephen 1981;Agrawal et al 1980;Ho and Tai 1988;Valerio et al 1988;Mugica et al 2002;Akhler and Madany 1993;Folio et al 1982;Dube 1992;WHO 2002;Lazaridis et al 1999). Cadmium is a toxic metal for most living species and is emitted by electroplating and battery production industries.…”

“…Increased traffic fleets and higher demand for energy are the most notable air pollution causes (Barrat 1990;Melgarejo et al 1986;Stephen 1981;Agrawal et al 1980;Fuleka et al 1983;Ho and Tai 1988;Dube 1992;Musonza 1996;Musekiwa 1998;Zvimba 1999;Zendera 2001). Research has shown that airborne particulates of small size can cause severe respiratory problems particularly in urban areas (Nriagu 1988;Barrat 1990;Pope et al 2002;Stephen 1981;Mugica et al 2002;Salma et al 2002a;Morris 2001;Yamaguchi and Yamazaki 2001).…”

Levels of TSP, PM(10) and PM(2.5) as well as levels of Pb, Co, Ni and Cd in TSP, PM(10) and PM(2.5) have been determined in atmospheric particulates collected at Loius Mountbatten School (Harare). The samples were collected for a period of 6 months from July to December 2002. The average levels of TSP, PM(10) and PM(2.5) measured at the site are 106.11, 59.70 and 40.55 mg m(-3) respectively. The average level of TSP at Loius Mountbatten School is 106.11 mg m(-3), which is higher than the annual WHO guideline limit of 90 mg m(-3). The average level of PM(10) measured at Loius Mountbatten School is 59.70 mg m(-3), and is higher than the US-EPA and UK-EU guideline limit of 50 mg m(-3). The average level of PM(2.5) measured at the site are also higher than the WHO and US-EPA annual guideline limit of 15 mg m(-3). The analysis of metal concentrations in TSP, PM(10) and PM(2.5) was done using Graphite Furnace Atomic Absorption Spectrometry (GFAAS). The analysis showed the following average elemental concentrations: 0.157 mg Pb m(-3) in TSP, 0.166 mg Pb m(-3) in PM(10), 0.185 mg Pb m(-3) in PM(2.5), 0.009 mg Co m(-3) in TSP, 0.007 mg Co m(-3) in PM(10), 0.011 mg Co m(-3) in PM(2.5), 0.223 mg Ni m(-3) in TSP, 0.166 mg Ni m(-3) in PM(10), 0.180 mg Ni m(-3) in PM(2.5) and 0.005 mg Cd m(-3) in TSP, 0.006 mg Cd m(-3) in PM(10), 0.005 mg Cd m(-3) in PM(2.5). The levels of Pb and Ni were generally higher than those of Co and Cd and this could have been due to high traffic volumes and various industrial activities in the Workington Industrial Area.
