“…Environmental pollution with cement dust by alkaline property affects all ingredients of the ecosystem [8]. Cement dust pollution generally causes alkalization of the ecosystem by changing electrical conductivity, pH, and chemical composition of the soil [1,9]. Increasing soil pH values affects soil biological activities and enzyme activities that are highly related to soil moisture, temperature and pH [10,11].…”

Composite soils from conventional tillage (CT) and no-till (NT) fields under wheat (Triticum vulgare cultivar Dogu-88) were randomly collected (0-30 cm depth) in triplicate at 1, 5, 10, 15, 20 and 25 km distance to evaluate the effects of cement dust on soil basal respiration, microbial populations, enzyme activity and calculated soil quality (SQ) indices. Soil pH, exchangeable Ca and Mg, CaCO 3 , and alkaline phosphatase (AlkP) showed a significant linear decrease in total organic C (TOC), total C (TC), urease activity (UA), and bacterial populations, and soil biological quality (SBQ) showed a significant linear increase with sampling distance from the cement plant. Total N (TN), available P (AP), basal respiration (BR), acid phosphate (AcdP) activity, dehydrogenase (DH) activity, fungal populations, and SQ showed a quadratic response with sampling distance. Soil pH, CaCO 3 , TOC effective CEC, SBQ, soil chemical quality (SCQ), and SQ were significantly influenced by increasing distance.

“…Four fungal genera namely Aspergillus, Rhizopus, Penicillium, and Fusarium were isolated in the present study. Such genera were previously reported in different Libyan soils polluted by like these metals such as dust from cement factory [20] and iron and still factory [21]. The increased microbial population at polluted sites by this kind of water may be attributed to different metals which may feed some of these microorganisms [4].…”

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...

“…A recent study [68] revealed that Abu-Kammash (Libya) is contaminated with several toxic elements and petrochemical compounds, and that the soil should be not be used for agriculture until it is remediated to ensure human health. In Zliten, an area around a cement factory, the soil physicochemical characteristics (pH, water content, and organic matter) indicate a strong influence of cement dust that has settled on the soil from the factory [69].…”

Ecosystem services (ESs) are increasingly being used by many countries around the world as a framework for addressing the United Nations (UN) Sustainable Development Goals (SDGs). This review article of the usability of Libyan soil databases for ESs and SDGs is the first of its kind for North Africa. The objectives of the article are to: describe the available soil resources of Libya in relation to an ES framework; provide examples of the usability of Libyan soil databases for ES applications (e.g., provisioning, Healthy Eating Plate), and describe some of the typical disservices in the country. Desertification, salinization, and limited freshwater resources are the largest challenges (disservices) for agriculture and future development in Libya. Seawater intrusion in coastal areas due to rising sea levels has resulted in high concentrations of salts in irrigation waters, which can lead to low soil productivity. These challenges can be addressed by integrating Libyan soil resources into a market that transforms resources into goods and services to meet human demand in a sustainable manner, with non-market institutions mediating the interactions between humans and the environment. If Libyan soil resources are taken into account by both market and non-market institutions, it will lead to more efficient use of soil resources and also should enable the implementation of innovative strategies, such as integrated farming systems, non-soil-based agricultural production (e.g., hydroponics), and alternative farming practices.
