“…However the Ni levels reported in this work lies within the expected ambient Ni range of 0.001 to 0.500 μg m −3 as reported by Lambert and Wilshire (1979).…”

“…The difference between the level reported in this work and that by previous workers could be due to increased distance from the potential emission sources (motor vehicles). The expected Cd air concentration range is 0.004-0.090 μg m −3 as reported by Lambert and Wilshire (1979). Therefore the measured levels of Cd in TSP, PM 10 and PM 2.5 at Loius Mountbatten School fall within the expected range.…”

“…The values are lower than those measured in this work. The mean concentrations of Co at 250 USA sites in a study by Lambert and Wilshire (1979), was found to be 0.001 μg m −3 . Again this value is lower than the measured value for the sampling site.…”

“…Van Grieken et al (1982) reported Ni levels of 0.012 μg m −3 for Recife (Brazil) and Rio de Janeiro (Brazil), 0.034 μg m −3 for US Urban and 0.027 μg m −3 for Washington. Lambert and Wilshire (1979), reported on the average Ni concentration for USA as 0.03 μg m −3 . Dzubay et al (1982) and Stevens et al (1984), determined metal concentrations in fine and coarse particles in Texas.…”

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.

“…The composition of the sample may also affect the sensitivity for at least 15 elements. Lambert and Wilshire 142 have described the simultaneous determination of 26 elements, including arsenic, in ambient air samples collected on glass-fiber filters at 250 U.S. sites of the National Air Surveillance Network using NAA combined with a mini-computer. Ambient air levels for each element were defined in units of ng/m 3 .…”
