Atmospheric Level of Cadmium in Sokoto Metropolis, Nigeria.

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.
