Soil samples were collected from and around Zliten cement factory, Zliten town, Libya. Soil metals and microbial contents were determined. The results obtained for the examined physiochemical characteristics of soil in the area studied prove that cement dust from the Zliten cement factory in Libya has had a significant impact on the soil. The affected soil properties are pH and total calcium content. These characteristics were found to be higher than those in similar soils from the same area (unpolluted). The increment of soil pH in the same area may be a result of precipitation of cement dust over the years. Metal uptake from cement to plants and soil then affects organisms' bodies, a fact that seems to be reflected in this study. Different responses were found in each site. For instance, the dominance of fungi of soil was lowest at 100 m from the factory and the evenness and diversity increased at this site compared to 300 m from the factory and the control area.

Abstract-This study was carried out to investigate the effect of treated wastewater on soil chemical and physical properties. Field experiment was conducted in Misurata region in central Libya with water treatments of wastewater. The Soil physicochemical parameters such as, pH, water content, total soluble salts, Cadmium, Zinc, Lead, Cupper and Iron of soil added treated industrial west water. The results reveal that the some sampling sites were affected by industrial west water pollution. Soil water content ranged from 7.68 to 19.56. %. Total soluble salts ranged from 272.6 to 300 ppm and soil pH ranged from 7.7 to 8.0. and showed no appreciable differences within localities. The all tested metals increased from first location to the third location except Iron. The irrigation system had a significant effect on Total soluble salts and microbial flora. Isolated microbial flora consists of 4 fungal genera belonging to, Aspergillus, Penicillium, Rizopus and Fusarium. The latter and one of the Aspergillus spices (Aspergillus sp 3 ) may consider one of the resistance fungi to industrial west water due to its large colonies numbers isolated from water contaminated metals area.Index Terms-Soil quality, physicochemical parameters, west water interstitial. I. INTRODUCTION.The presence of heavy metals and residues from rod and town houses and industrial wastes has been found to be the causes of pollution in soil. wastewater possesses different biological, physical and chemical effects on the environment. Some physicochemical analysis of soil affected by industrial pollution significantly needed [1]. Microorganisms and human being received pollutants which is toxic when any kind of pollution come in and accumulating into the soil [2]. Nearly 90% of Cd, Ni, and Pb accumulated in the 10-15 cm soil depth when this soil irrigated with wastewater [3]. Although many of elements including heavy metals are required by living organisms for their normal function [4], these elements considered one of the most harmful industrial pollutants in the environment also at high concentrations, they become toxic. Its known that in environment, metals including heavy metals can be present as either dissolved elements or as suspended elements. These heavy metals can affect soil and its content including micoorganismes particularly fungi. Although, some fungi mentioned as heavy metals tolerant [4]. The presence of pollution-tolerant species is often used as an indicator of pollution resulting from industrial discharge in aquatic systems [4] With increasing evidence of the adverse effects of pollutants on soil, air, water and their populations, these environments have received much attention in recent years [2]- [4]. Changes in soil properties have been associated with environmental alteration that takes place, for example as a result of human activity. As soon as any kind of pollution contacts the soil surface its constituents enter inside the earth. Its metal constituents undergo several reactions which can affect soil including its chemical an...
