Abstract
The distribution of environmental pollutant, sulphur, over Kano municipality was monitored on the basis of the chemical analysis of Scots Pine (Pinus sylvestris L.) needles collected from randomly selected sampling points over the period 1995–1996. Of the five zones in which the municipal area was subdivided, two could be regarded as least polluted, two as moderately polluted and one zone as heavily polluted. The mean value of all measurements in the metropolis amounted to 1940 μgg−1 S with a co-efficient of variation of 38 percent.
