assistant lecturer Muwafaq Hussein Mohammed-lecturer in the Department of Environmental Pollution-ERC presented a lecture on Tuesday, 24/12/2019 at 12:00 entitled                                 “Floating Treatment Wetlands-New Technology for Wastewater Treatment”.

The lecturer stated that constructed wetlands (CWs), in the recent decades, are being increasingly used for water quality improvement during wastewater treatment. This is, in part, a result of increasingly strict water quality standards which mean that conventional secondary treatment may not be sufficient to comply with targets in receiving waters. CWs are engineered ecosystems that exploit different natural remediation mechanisms from biotic and abiotic components for water quality improvement. These systems have been created with different designs, including free water surface constructed wetlands (FWS CWs) and subsurface flow constructed wetlands (SSF CWs). These wetlands have been used worldwide as a tertiary polishing stage during wastewater treatment, and their performance in removing nitrogen were evaluated. One advantage of FWS CWs is that they are inexpensive to operate and maintain. However, inadequate surface area for microbial growth for a given volume and the lack of direct contact between water column and plant roots are deemed critical limitations in their performance for removing nitrogen.

To overcome these limitations, one possible solution is the floating wetland technology. Floating treatment wetland (FTW) is an eco-engineered system, that integrates the functions of the FWS CW and floating treatment island for water quality improvement. Increasing decontamination surface areas and direct contact with contaminants as well as harnessing range of biogeochemical processes such as microbial transformations, plant uptake, and physical filteration to eliminate contaminants are the central mechanisms of applying FTWs. FTW has, therefore, been developed as an lternative and effective wetland design for sewage-industrial wastewater quality improvement.

Dr. Mohammed Muayad Taha-lecturer in the Department of Environmental Technology-ERC presented a lecture on Tuesday, 17/12/2019 at 12:00 entitled "Environmental Pollution and Genetic Mutations”. The lecturer stated that environmental pollution is one of the most serious disasters that faces human in the modern era where it means the deterioration of the environment as a result of a defect in it so that it loses its ability to perform its role in self-disposal of pollutants according to natural processes.

Several studies have shown that environmental pollution has significant effects on human life that exceed all previous expectations, and it causes dangerous genetic mutations in DNA that have not been taken into consideration by many researchers. In the recent period, there have been cases of births of children who are suffering from so-called “Mongolian” down syndrome (MN) resulting from a change in the chromosomes where there is an additional version of chromosome 21 or part of it in the cells, which causes a change in the genes. Doctors point out that this issue is not due to traditional and well-known causes, including the mother’s age, but rather to exposure to some types of environmental pollution that distort some genetic genes or cause defects therein. At the end of the lecture, the lecturer recommended the following:

* The importance of follow-up this issue in our medical institutions and taking it into account in terms of researching into its causes

* Avoiding the excessive use of chemicals in the home such as detergents and powders in general and harmful pesticides in particular

* Following an appropriate diet that contains the essential nutrients and fibers that reduce the effects of chemical contamination. Many doctors and nutrition experts believe that the presence of nutritional supplements is important for human health such as fiber, vitamins and nutrients such as magnesium, as well as reducing caffeine and substances that are harmful to health.

The director of ERC (Prof. Dr. Abdul Hameed M. Jawad Al-Obaidy) presented a lecture on Thursday, 5 December 2019 entitled “Pollution of Water Resources”

where the most important key messages that characterized the reality of the water resources in Iraq were discussed under specified conditions of limited availability and scarcity of water and thus, its inability to meet the requirements of current and future investment.

The main reasons for these conditions are relating to increasing the population density, water consumption and development of technological capabilities that negatively affect the environment, which led to the emergence of competition for water uses and environmental pollution.

At the end of the lecture, the lecturer discussed the possibility of hard research in the above reasons and adopting them as scientific research guidelines in the field of water resources within the scientific plan based on long-term strategic extents of the ERC in the coming years.
