Compositions of dry and wet atmospheric depositions vary depending on geographic locations and industrialization. Fog waters were collected from different regions of Bangladesh along with rain, sub-surface irrigation water and dust particles from Gazipur and compositions were analyzed. The compositions of fog water varied greatly among locations. The ammonium nitrogen (NH⁺₄-N) content was the highest (36 - 37 ppm) in Gazipur district and the lowest in Sylhet district (3.2 - 3.6 ppm). Phosphorus (5.2 - 5.5 mg/L), K (29.5 - 30 mg/L), S (11.0 - 11.5 mg/L), Zn (2.9 - 3.3 mg/L), Na (11.7 - 12.5 mg/L), Ca (22.0 - 23.3 mg/L) and Cd (0.14 - 0.17 mg/L) contents were also higher in Gazipur district. Dust particles, rain and sub-surface irrigation water of Gazipur district contained considerable amounts of macro and micro elements. We conclude that dry and wet atmospheric depositions varied depending on locations and industrial development. Such study needs to be correlated with ecological consequences and soil fertility management.
