Abstract:
Reliable monitoring of atmospheric constituents is usually very
technical and involves the use of sophisticated equipments. Most of these equipments
are not easily accessible to many, especially in a developing country like Nigeria.
Consequently, a simple sampling technique was designed to collect atmospheric
cadmium in Sokoto metropolis, which was subsequently analyzed using Atomic
Absorption Spectrophotometery (A.A.S). The method yielded analytically reasonable
results which were in conformity with many research findings as well as international
standards. The improvised technique was economical, reliable and easy to operate.
The results in (ng/rn ') showed mean Cadmium concentration of 0.3±0.1. This is in
agreement with the findings of WHO (1987), i.e., 1 to 5 ng/m3 in rural areas,S to 15
ng/m3 in urban areas, and IS to 50 ng/m-' in industrialized areas.
