Within the cultural season of ERC a seminar was held on Wednesday, 15/07/2015, Mr. Talib K. Al-Shemary presented a seminar entitled: "Assessment of pollution by heavy metal concentrations at Hawr Awm Al-Warid/Al-Huwaiza Marsh/Messan Governorate.". The lecturer sowed that HawrAwm Al-Warid  locates in the Northwest of Hawr Al-Huaizeh with an area of 70 square kilometers, 90% of the marsh area covered by dense reeds and the main water source is Al-Hsaitchi River. The pollution of environment by high concentrations of heavy metals may result in severe environmental impacts on the bio-availability for those environments in addition to the potential health effects  on the population of those areas. In his study, he estimated concentrations of some heavy metals in water of Hawr Awm Al-Warid. The aim of this study is to form an idea about the background of the presence of heavy elements in water of Hawr Awm Al-Warid and to indicate whether there is a presence of contamination with heavy metals in the marsh  by comparing the results of laboratory tests of the current study with the results of tests prior to the study, and showing the changes and variations in concentrations of heavy elements at marsh water between the two periods. The study showed the presence of high concentrations of the elements  manganese, nickel, chromium, lead and zinc, the study suggested that the petroleum activity in the region in the past few years and agricultural activity based on the chemical fertilization are the reason for the rise in the concentrations of heavy metals in Hawr Awm Al-Warid.
