“…This behavior might be due to the source of the PAHs. A similar uniform distribution of individual PAHs was also observed in the Pearl River Estuary coastal wetland soils (Khadhar et al, 2010), but the patterns differed from those in Qatar, which were dominated by 4-6 ringed PAHs (Soliman et al, 2014).…”

“…This type of waste can be implemented as organic fertilizer, valuable in nitrogen and others macronutrients [CHENG et al 2007]. However, taking into account numerous requirements of environmental management, sewage sludge become a problem [HARRISON et al 2006;KHADHAR et al 2010]. An unfavorable feature of this waste is specific, amorphous structure, which favors anaerobic decomposition and production of gases harmful for health and environment such as ammonia, hydrogen sulfide, aromatic hydrocarbons and others.…”

After entrance to EU in 2004, the management of sewage sludge has become more and more important problem for the new members. In Poland, one of the most promising technologies is composting process of sewage sludge with carbonaceous materials. However, the high price of typically used cereal straw forces the specialists to look for new and cheap materials used as donor of carbon and substrates creating good, porous structure of composted heap. This work presents the results of sewage sludge composting mixed with sawdust and maize straw used to create structure favorable for air exchange. The results show dynamic thermophilic phase of composting process in all cases where maize straw was used.

“…Le bassin versant du Golfe de Tunis est drainé par un réseau hydrographique ramifié, caractérisé par quatre écoule-ments principaux: la Medjerda, le canal El Khlij, la Méliane et l'Oued El Bey. D'une manière générale, les cours d'eau constituent l'exutoire naturel des eaux de ruissellement mais aussi des effluents domestiques, des effluents industriels et des rejets du drainage agricole, qui peuvent contenir plusieurs type de polluants métalliques et organiques tels que les hydrocarbures aromatiques polycycliques (Khadhar et al 2010) et qui sont parfois insuffisamment épurés. En conséquence, les eaux des oueds du bassin versant du Golfe de Tunis sont le plus souvent de qualité physico-chimique et bactériologique médiocre et sujette à des variations importantes et brutales.…”

Résumé L'Oued El Bey, qui draine 60% de la charge polluante hydrique de plusieurs agglomérations urbaines du Nord-Est de la Tunisie, est un exemple représentatif du transfert des métaux lourds résultant de l'activité industrielle et urbaine. Il fournit une indication sur le devenir et la répartition des métaux lourds dans le Golfe de Tunis. Dans la fraction dissoute, Cd, Pb, Co et Hg ne sont pas détectés mais Zn varie entre 0,01 et 0,07 µg/L. Les concentrations du Mn, Zn, As, Ni, Pb, Cu et du Cd sont très élevées dans la fraction particulaire par rapport à la fraction dissoute, avec un coefficient de partage Kd de l'ordre de 10 6 , ainsi que dans les sédiments du lit de l'oued pour Pb et Zn. La pollution par les métaux la plus élevé de l'Oued El Bey a été trouvée pour Zn, Pb et Cu: les concentrations variaient respectivement entre 1698,9 et 14575, de 0 à 2153,7 et de 0 à 3431,8 µg/g. La variation spatiale des teneurs en métaux lourds confirme l'effet des eaux usées rejetées dans l'Oued El Bey. Les teneurs de ces métaux lourds dans les trois phases dissoute, particulaire (MES) et sédiments confirment que la MES constitue le vecteur de transport principal via la Sebkha Soliman vers le golfe. L'examen des rapports des différents éléments (Pb, Cu et Cd) par rapport au Zn dans les sédiments de l'oued montre une augmentation au niveau de la confluence de l'Oued El Bey et de son affluent l'Oued El Meleh, ce qui signifie que les apports sédimentaires de cet affluent contrôlent la signatutue chimique des sédiments de l'Oued El Bey.Mots clefs Oued El Bey; métaux lourds; fraction dissoute; matière en suspension; sédiment; rejets des eaux usées Transport of heavy metal pollution from the Wadi El Bey basin toward the Tunisian GulfAbstract Wadi El Bey, which drains 60% of the pollutant load of several urban centres in the northeast of Tunisia, provides a good example of the transfer of heavy metals that result from industrial and urban activity, and can be used to show how these metals are transported and discharged into the Gulf of Tunis. In the dissolved fraction, Cd, Pb, Co and Hg were not detected, while the Zn content varied between 0.0129 and 0.0658 µg/L. The heavy metal (Mn, Zn, As, Ni, Pb, Cu and Cd) concentrations were higher in suspended particulate matter compared to the dissolved fraction, with a partition coefficient Kd of about 10 6 . The highest metal pollution of Wadi El Bey was found for Zn, Pb and Cu: the concentrations varied between 1698.9 and 14575, 0 and 2153.7, and 0 and 3431.8 µg/g, respectively. The variation in the spatial distribution of heavy metal concentrations confirms the wastewater (domestic and industrial) impact on the water quality of Wadi El Bey. By comparing the heavy metal concentrations in the three phases-dissolved solids, suspended matter and sediments-we concluded that the metal pollution was transported via the Soliman salt flat to the Gulf of Tunis principally by the particulate fraction.Comparison of the concentration of various elements (Pb, Cu and Cd) in the sediments of the riv...
