The aim of this work is to study the mobility of polycyclic aromatic hydrocarbons, mainly naphthalene, in an agricultural soil in road environment. The recorded naphthalene concentrations in soil’s surface horizons (19.37 ± 0.32 mg∙g-1), allowed to highlight that the traffic and road’s infrastructures are an important toxic source of naphthalene to the environment. This pollutant can disperse and fall dry or wet on the edges of the pavement, carried by storm water runoff into the ground. This naphthalene accumulation is influenced by the physical and chemical parameters of the soil (pH, cation exchange capacity, clays rate). High levels of naphthalene in soil were observed at low pH (r = -0.25**), in contrast, soil cation exchange capacity (CEC) and the clays rate are positively correlated with these levels (r = 0.20* and r = 0.17**). © 2017 ALMA MATER Publishing House, “VASILE ALECSANDRI” University of Bacău.

Feldspars are Common within the earth's crust, but only the potassium and sodium feldspars are highly sought in the ceramic and glass industries. To be utilized, these materials must contain very little harmful impurities especially iron and silica. The Ain Barbar exploits the feldspar material (orthoclase) with respective average grades of 73.26% SiO2; 14.71% Al2O3; 7.78% K2O; 0.79 % Fe2O3 and 0.33%Na2O. However, there is a very high rate of quartz which decreases the value merchant product and a high iron content which gives to the product coloring aspects making it unmarketable. For this purpose a mineralogical and chemical characterization, were performed on samples obtained from site extraction of the useful substances. Pre-concentration grain size test, were followed by physical and a physic-chemical concentration (magnetic separation and flotation), by new reagent to provide a valuable quality product which is acceptable for ceramists and glass. During this study, the parameters are examined effect of current intensity the coil, pH, concentration of the different reagent used. The results collected from the chemical analysis of size fractions, reveal total of SiO2 contents vary from 70.89 to 75.61% in the size fractions. As for the ferriferous inclusions contents are 0.18 to 1.06 % Fe2O3 showing excess iron in the raw material, that does not meet the required standard (Fe2O3< 0.03 % and quartz < 8%). Also, note that the iron oxide content increases as the particle reduction. The contents of K2O and Na2O and SiO2 are homogeny almost in all size fractions.

In recent decades, emphasis was on improvement the Algerian mining industry by creating new smelting complexes such as the metallurgical plant in Bellara (Jijel) with a productive capacity of 5 million tons per year to satisfy the increasing demand in steel. The present study was conducted at Anini's iron ore mine to develop its mineral resources in order to use it in the metallurgical industry (Arcelor-Mittal complex of Annaba Algeria).Representative samples were collected from the iron ore mine of Anini in northwestern of Setif. A series of chemical and mineralogical analysis was performed. However, the analysis by (XRD, SEM and XF) shows that this mineral is hematite iron type clay and siliceous gangue. Moreover the mean levels of Fe2O3, SiO2 and Al2O3 are 50.52 %, 24.06% and 7.80%. The results obtained with the magnetic separation in wet process reveals significant content of iron ore with 65.1 1% of Fe2O3, 2.46% SiO2 and 1.73% Al2O3. These findings proved the effectiveness of this treatment to provide the criteria imposed by the steel industry. As well as the resulting wastes can be used in the cement industry.

Urbanization and increasing of industrialization have played a key role in the evolution of Annaba region. These activities were synonymous with economic and social progress. Annaba has known recently many problems in ecological terms, due to various urban pollutants (waste disposal, mining, smelting, and chemical industries etc.). In fact, large concentrations of chemical substances introduced into the environment may represent a potential risk for all living organisms, including humans. In our study, soil samples were collected from different sites of the Annaba city. The content of eight soil heavy metals (Pb, Cu, Zn, Cd, Fe, Mn, Ni and Co) was measured in the collected samples. According to analysis results, the highest degree of soil contamination with lead, copper, iron, manganese and zinc, was found in Annaba center and the area of sidi Amar located in the southeast, near the steel plant of El Hadjar. Meanwhile, the content of cadmium, cobalt and nickel in soils of all four studied sites, was at the level of geochemical background.

Excessive concentrations of heavy metals introduced into the environment may represent a potential risk for all living organisms, including humans. Annaba has a strategic geographical location in terms of its natural potential, its various infrastructures, etc. The dense of industrial base characterized by the existence of large industrial complexes such as: Arcelor Mittal (steel), Fertial (fertilizer phosphatic), Ferrovial (metallurgy and boiler).Annaba is also one of the most polluted industrial and urban centres of Algeria. A long-term monitoring of air quality parameters in this area gives evidence of pollution by heavy metals. In this study, soil samples were collected from different sites of the city and analysed by atomic absorption spectrometry. The assessment of heavy metal pollution was derived using the total index of pollution. According to results study, the degree of technogenic pollution rated as “moderately threating” near the steel plant of El-Hadjar and in the centre of Annaba. Meanwhile, the relative reduction in the value of biomass in radish sprouts in the remaining three zones was 10-25%, whereas the protein content in the roots of radish plants were at the level of 0.6 - 0.8 times in comparison with the reference area of airport. © 2015 Vasile Goldis University Press.

Soils contamination with heavy metals is a major concern and common problem in Algerian megacities. The case of Algiers and Annaba which have known in last years a rapid urbanization and increasing of industrialization. These activities were synonymous with economic and social progress. Moreover, they led to many ecological problems, due to different urban pollution: waste disposal, noise pollution, atmospheric, industrial, soils pollution etc. It is well known that heavy metal contamination is a serious threat to the environment. In fact, large concentrations of heavy metals introduced into the environment may represent a potential toxicity for all living organisms, including humans. The present study was conducted to determine the features of heavy metals adsorption by soils collected in Algiers and Annaba. Wherefore the soil adsorbency to heavy metals was assessed by plotting the isotherms and determining the maximum adsorbency. Whereas results study on sorption isotherms of Algiers soils show that the tested elements can be arranged in the following descending order: Pb> Cu> Zn> Cd. According to study results, the highest value of maximum adsorption capacity of soils taken in four zones of Annaba in relation to lead, zinc, cadmium and copper, were respectively 7; 6; 4.5 and 3 times higher than the minimum. These findings could play a key role to effective assessment of soil pollution with heavy metals in the study area.
