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