The atmospheric corrosion of Calabar, Cross River State environment has been investigated for 12 months using weight loss technique. The extent of pollution of the environment was also determined via measurements of the precipitation and air quality parameters. Apart from the suspended particulate matter (SPM) (113-630 μg/m3) and NO2 (> 0.06 ppm) values, other measured atmospheric parameters (CO < 9.2 ppm, NH3 < 4.3 ppm and SO2 < 0.380 ppm) and precipitation parameters (pH > 5.0, conductivity < 60 μScm-1, TDS < 41.48 mg/l, TSS < 0.05 mg/l, NO3 - < 3.00 mg/l, SO4 2-
