From the restoration point of view, heavy metals distribution and seasonal variation were studied in the re-flooded marshes of the Mesopotamia, southern Iraq. As part of the ecological recovery assessment of these newly inundated marshes, it is important to investigate the extend impact of 13 years of desiccation after five years of inundation on the heavy metals mobilization from the marshland downstream into the Shatt Al-Arab River and examine whether these marshlands retain their role of acting as sink of metals. The result shows significant differences between the re-flooded marshes versus the reference marsh, which indicates that desiccation caused changes in environmental variables and divided the one homogeneous system of the Mesopotamia into separated systems. In addition, the special distribution of heavy metals shows that Al-Hawizeh and Al-Hammar marshlands were efficient for metals reduction, especially for Ni, while the Central marshland has the major contribution as source to metals. As a conclusion, the recovery potential of three marshlands is strongly controlled by the hydrological status of the marshland and the degree of the desiccation impact. The environmental status of the semidried marshes, Al-Souda north and Um Al-Niaaj, as well as the completely Abu Zarag dried marsh is exhibiting a more positive recovery degree than the other monitored marshes in the Mesopotamia in comparison to the reference marsh.

This paper aims to analyze the geographic distribution of air pollutant concentrations in Basra Province, Southern Iraq, and to cartographically determine the spatial variation of air pollution levels as well as to recognize the hottest spots of air pollution within the study area, and conclude that the levels of air pollution in the study area are spatially varied, with an irregular spatial pattern and some hotspots.

The study included the nitrates, phosphates loads and some properties of water quality in the Shatt Al-Arab River at Basra city center . There were used to identifying the state of water and nutrient movement in this part of the River starting from the Shilha location north of Al-Hartha to ​​Al-Bahadriyah north of Abu Al-Khasib, which represents the section that contains dense human  population at Basra city center. Fourteen sampling stations were selected within the study area during the summer and winter periods, as well as during the morning and evening at the same day. The study showed that the phosphate and nitrate salts have not transfer out of this river section. Also there were no significant impact of the side river branches on the water quality of the Shatt al-Arab River because of the low discharges from these branches compared to discharge of the main Shatt al-Arab River.
