Groundwater is the main source of water in Mediterranean, water-scarce, semiarid regions of Tunisia, Africa. In this study of the Korba coastal aquifer, 17 water wells were studied to assess their suitability for irrigation and drinking purposes. Assessment parameters include pH, salinity, specific ion toxicity, sodium adsorption ratio, nutrients,...

Treated wastewater (TWW) reuse has increasingly been integrated in the planning and development of water resources in Tunisia. The present study aimed the evaluation of the environmental and health impact that would have the reuse of TWW for crops direct irrigation or for the recharge of the local aquifer in Korba (Tunisia). For this purpose water...

In order to identify the source apportionment of particulate matter PM 10 and PM 2.5 in the southern Mediterranean coast of Tunis (Tunisia), three different sites characterized respectively by traffic, industries and being an urban background area are studied. The chemical characterization included a gravimetric determination of atmospheric particl...

Wetlands are critically important for biodiversity and human wellbeing, but face a range of challenges. This is especially true in the Mediterranean region, where wetlands support endemic and threatened species and remain integral to human societies, but have been severely degraded in recent decades. Here, in order to raise awareness of future chal...

Annaba gulf is a coastal area (southwestern Mediterranean Sea) that receives large diffuse inputs from Fertial plant, Seybouse wadi and Boujemaâ wadi, which are influenced by anthropogenic activities. Wastewaters and surface waters and sediments from these sites were analyzed for Polycyclic Aromatic Hydro-carbons (16 PAHs) by using gas chromatograp...

Virtually all sub-regions of the Mediterranean Basin, on land and in the sea, are impacted by recent anthropogenic changes in the environment. The main drivers of change include climate (temperature, precipitation, atmospheric circulation, extreme events, sea-level rise, sea water temperature, salinity and acidification), population increase, pollu...

Annaba Bay is the ultimate receiver of innumerable chemical substances issued from various anthropogenic activities. These telluric releases could have biocidal properties. In order to preserve the quality of the coastal waters and to limit these flows that are dangerous for the marine environment, seasonal monitoring of water quality of the two ma...

To overcome classical jar test limits of water treatment plants and offer substantial savings of time and money for operators, artificial neural network technique is applied in this study to large databases of three treatment plants with different processes in order to build models to predict the optimal dose of coagulant. Pre-modeling techniques,...

The seasonal assessment of trace metallic elements in Seybouse Wadi waters and sediments is performed by principal component analysis (PCA). This Wadi is the second of Algeria considering its length and vast basin, and opens into the coastline of Annaba in the Mediterranean Sea. Monitoring mineral micropollutants showed that waters are primarily co...

Water is considered a major social and political issue. This article stands out by its quantification of the impact of socio-political disturbances on social behavior regarding the consumption of drinking water. It also allows the monitoring of fluctuation of the economic pattern through the main economic sectors during these disturbances by the st...
Article

Combining bioassays and analytical chemistry screenings is a powerful approach to assess emerging organic micropollutants which are the main contributors to toxic potentials in complex mixtures of water matrices. The aim of this study was to assess the cytotoxic effect of the occurrence of emerging organic micropollutants discharged into river wate...
Article

Climate change has multiple impacts on water sector. This paper analyzes the observed trends and fluctuations related to the drinking water field in Tunisia through its three main steps: capture, treatment and distribution, by a quantification of the effects of climate change on each of these steps. At dams, several scenarii have shown through proj...

Modelization of local atmospheric quality beeing difficult, it is important to monitor the major air pollutants in order to know, understand and eventually remedy the pollutions. The monitoring of the air quality in urban area is done in Tunis, capital of Tunisia, from 2003 to 2014, for the major gazeous pollutants: tropospheric ozone O3, nitrogene...
Article
Full-text available
Assessment of urban pollution by O3, NOx and SO2 and local interactions with weather parameters is conducted in the capital Tunis (Tunisia) between 2003 and 2014. It established the distribution maps of the gaseous pollution and highlights the interactions between ozone and nitrogen oxide concentrations as well as meteorological parameters by a sta...

It is among the basic missions of the National Agency for Environmental Protection (NAEP) to preserve and improve the quality of our nation's air. In order to accomplish this mission, the Agency must be able to evaluate the status of the atmosphere compared to clean air standards and historical informations. That's why the NAEP established since 19...

In order to characterize, classify and evaluate the suitability of Medjerda River water for irrigation, a hydrochemical assessment was conducted. It accounts for 80 % of the total Tunisian surface water. In this paper, hydrographical methods and PHREEQC geochemical program were used to characterize water quality of Medjerda River, whereas its suita...

The overexploitation of Korba aquifer mainly for irrigation purposes at a rate of 103 % caused a decrease in aquifer level in addition to its deteriorating water quality. Since July 2008, treated wastewater from Korba plant has been used to artificially recharge the aquifer at a site close to the treated wastewater plant. The purpose of this projec...
