The influence of Abo Zabal fertilizer factory on air quality and soil contamination
were investigated. Air pollution index of different sites and soil pollution indices were
calculated. The metal contamination in the soils was evaluated by calculating
enrichment factor (EF), contamination factor (CF), geo-accumulation index (Igeo) and
pollution load index (PLI). Soil quality for total heavy metals in the study area was
evaluated. The factory was found to change the reaction of the soil to become acidic
and all heavy metals were shown to be high at the factory site and decreased with
increasing the distance from the factory. This pollution of the environment caused
changes in the vegetation of the study area.
