Current Activities Conferences Emerging Pollutants in Water
Emerging Pollutants in Water PDF Print E-mail
 Conference Overview

       

        Surface water and groundwater contaminated by municipal and industrial sources, as well as diffuse sources from urban and agricultural areas, continue to build up pollution levels in the environment. Environmental legislation, even in highly developed countries, mostly deals with conventional pollutants and the so-called priority pollutants (POPs, pesticides, toxic metals, radionuclides, etc.). Only recently, attention has started to shift towards emerging pollutants.

 

Themes
  1. Analytical methods for the detection of emerging pollutants and their transformation products
  2. Toxicity of emerging pollutants and their water-related properties (degradability, solubility, sorption)
  3. Emissions and treatment of emerging pollutants
  4. Occurrence and fate of emerging pollutants in surface water and groundwater, and mathematical modeling.

        Emerging pollutants are not regulated by international or national environmental legislation, and conventional methods of treatment often do not remove them. The elimination of these chemicals requires a multidisciplinary approach. Water and wastewater treatment is not the sole solution to removing these pollutants from the environment. Certain treatment techniques can remove these chemicals; however, such systems tend to be very costly. Also, most of the countries have either limited or no water purification and wastewater treatment infrastructure, rendering the implementation of new technologies infeasible.

For most of the emerging pollutants, risk assessment and ecotoxicological data are not available and it is, therefore, difficult to predict which health effects they may have on humans, terrestrial and aquatic organisms, and ecosystems. Concern has been growing, especially in the past 20 years, over the increasing incidence of human organ disorders, chemical accumulation in human tissue, and the like. Fertility problems and neurological issues are also on the rise.
Therefore, it is very important to know the occurrence, distribution and fate of emerging pollutants in surface water and groundwater. Degradation and sorption are the major factors affecting attenuation of emerging pollutants in river and groundwater systems.

The impact of climate change (declining low flows, etc.) might aggravate emerging pollutant challenges in certain regions of the world.

Having this in mind, the UNESCO International Hydrological Programme (UNESCO-IHP), UNESCO Category II Center: Water for Sustainable Development and Adaptation to Climate Change (WSDAC), Jaroslav Černi Institute for the Development of Water Resources and Serbian Water Pollution Control Society are organizing a UNESCO Conference "Emerging Pollutants in Water", to offer the needed technical guidance.
