A study of an environmental assessment of dust fall and the associated heavy metal contents was conducted during the
period from the first of March 2011 to the end of February 2012 at adjoining area of a phosphate fertilizer plant. Around
the industrial area 8 dust fall stations were established and one of them was built upwind far from pollution activities to
be taken as a control sample. Dust fall samples collected monthly weighed and then prepared to be analyzed through
Inductively Coupled Plasma-Mass Spectroscopy (ICP-MS) to obtain heavy metal concentration. Meteorological parameters
influencing the distribution of dust fall such as wind speed and direction, temperature, humidity, rain fall and
pressure were determined. Results showed that deposition flow rates were 38.2. 47.5, 57.7, 44.3, 39.4, 38.2, 42.7 and
5.9 g/m2·month for the sites No., 1, 2, 3, 4, 5, 6, 7 and 8 respectively, and were compared with the findings of other investigators
of like industrial areas worldwide. Levels of heavy metal As, Cu, Pb, Zn, Cd, and Hg in the deposited dust
fall were 3.30, 26.46, 22.33, 235.00, 4.53 and 3.80 μg/g respectively. Enrichment coefficients of the heavy metals in the
dust fall were found to be significant and reached the values 1.81, 0.90, 0.85, 0.65, 0.41 and 0.35 for zinc, lead, cadmium,
copper, mercury and arsenic respectively. The paper ends with results and recommendations suggesting a methodology
to remediate the investigated area polluted with heavy metals and control measures for the fertilizer plant to
reduce pollution into the surrounding environment.
