Biologie Résumé : From an agricultural soil sample from the region of Ain M'Lila and a sample of activated sludge from the Ibn Ziad-Constantine wastewater treatment plant, we isolated respectively 80 and 18 phenotypically different actinobacteria. The samples in question were the subject of a physic-chemical analysis. Firstly, we conducted a functional study by testing these isolates on a minimum solid medium supplemented with 500 mg/L of different pesticides most commonly used in Algeria, namely the Ortiva and Rodazime fungicides. Insecticides like Karate, Phoenix, Dursban and Cypermethrin.
Herbicides in several commercial forms such as Mamba, Zoom, Glyphosate, Herbasate, Roundup, Traxos and Axial to characterize their abilities to use these pesticides as the sole source of carbon and energy. The results showed that the majority of isolates had the ability to degrade these synthetic compounds. Thus, in this thesis work, we have been interested in testing the ability of these isolates to degrade BTEX, which is an important family of volatile organic compounds. They contaminate various ecosystems such as air, surface water, groundwater and soil. These compounds have very toxic effects on humans and animals. Several microorganisms have been tested for their ability to degrade BTEX. Others have unfortunately been neglected despite their interesting metabolic and physiological aptitudes. In the present study, we tested the degradation of these compounds by isolated
actinomycetes taken individually or in consortia. The results of growth and degradation kinetics showed that 20 actinobacteria and 2 reconstituted consortia were able to use at least one BTEX compound as the sole source of carbon and energy. Of these, four from activated sludge and one from agricultural soils degraded all these volatile organic compounds in vitro under aerobic conditions at concentrations ranging from 1400 to 1500 mg/L in 72 to 96 h of incubation. The second part of this work aimed to identify active isolates. The physiological study informed us about the remarkable metabolic diversity of the isolates tested. In addition, a taxonomic study was conducted by sequencing 16S rRNA of 25 strains. This identification showed that twenty-one of these isolates belonged to the genus Streptomyces and three to the genus Nocardia. This result is very encouraging and shows that actinomycetes that come from sewage treatment plants and agricultural soils have the ability to
biodegrade these organic volatil compounds and pesticides. The isolated strains are excellent candidates for bioremedion of terrestrial and aquatic sites polluted by these xenobiotics.

Titre : Caracterisation et origine des PM10 et des elements metalliques dans une zone urbaine de la ville de Constantine.

Exposure to PM10 containing metallic elements is a major health concern, particularly in urban
areas, the aim of this work is to characterize the metal fraction of fine particles emitted in urban areas and identify their main sources. PM10 samples were collected at the urban site of Zouaghi for a yearlong period (January 2015-February 2016) using a high volume sampler (HVS). This study aimed to characterize and identify the main sources of the associated metallic elements. After acid digestion, PM10 were analyzed for a total of 48 elements by ICP-AES and ICP-MS for major elements and trace elements respectively. The annual mean concentration (55.7 μg/m3) was almost 3 times higher than the WHO recommended ambient air quality guide value (20 μg/m3). A clear seasonal pattern, with higher concentrations in spring and autumn, was observed. However, metal species concentrations did not show significant seasonality. Ca was the most abundant element. Enrichment factor analysis indicated that Pb, Sb, Cd, Bi, As, and Zn were mainly originated from anthropogenic sources. Cu/Sb, Ca/Al, Zn/Pb, La/Ce, and V/Ni ratios were calculated and compared to ratios reported in previous studies. A significantly higher Ca/Al ratio was dominant indicating the influence of construction dust, while a low Zn/Pb ratio was the consequence of high Pb concentrations due to leaded gasoline use. Principal Component Analysis allowed to identify four main groups of sources: crustal aerosol for Al, Fe, Ti, Li, Mg, Ba, Sr and rare earth elements (REE’s) (47%), soil and road resuspension for Cr, As, S, P, V, Ca, Zn, Sn, Nb, K, Mg, Ba, Sr and Li (27%), traffic emission for Pb and Be (8%), and a metallurgical Cd and W source (6%). The results of the source apportionment analysis indicate that natural dust originating from Saharan dust outbreaks (SDO) and resuspended dust is the main source of elements in PM10 in the region of Zouaghi in Constantine.

It is, therefore, of utmost importance to address this problem in order to estimate particulate matter (PM) concentration levels, to assess the exposure of residents to PM10 and PM2,5, to identify potential sources of the collected particles and propose lines of work that could provide answers to the troublesome contribution of road traffic to the measured PM urban
levels.
Two sampling sites were selected. The first sampling site was located in the urban area of Daksi which is characterized by heavy traffic heading towards the city center to the south and the residential areas to the north. The second site was located at the entrance of the campus of the Faculty of Earth Sciences at Zouaghi and is close to national road 79, where traffic is among the heaviest in the city of Constantine.
Statistical techniques have been successfully used to identify and characterize the sources of PM and trace metals. The application of factor analysis and enrichment factors allowed to identify polluting sources such as soil dust resuspension, the earth's crust and urban traffic as the main sources of PM. The tram's construction site on the other side of the road along the measurement site was another important anthropogenic nearby source. Traffic is
causing high levels of Pb because Algeria is one of the few countries to use lead additives in gasoline.
To identify external sources and their geographical position, air mass back-trajectories were calculated with HYSPLIT4 model. Saharan dust was identified as a major source of PM and Fe. The Mediterranean sea was identified as the main source of Na, Mg, K and Ca.
