Background Air pollution significantly affects quality of life. In developed countries critical concentrations of particulate matter (PM), ozone (O3) and heat-stress have a damaging impact on health and the environment. Many studies have also demonstrated the connection between PM and rates of hospitalisation, chronic obstructive pulmonary disease and premature death. According to data published by the World Health Organisation, the average life expectancy in Poland is 10.7 months shorter because of air pollution. Therefore, it is necessary to build up knowledge of the complex interactions between pollutants, weather conditions and human health. Activities in this area should include complementary issues, such as long-term monitoring of human health and the quality of the environment, including the use of spatial modelling methods for air quality and the creation of short-term forecasts of exposure to high concentrations of pollutants. Information obtained as a result of modelling and forecasting can be used to support environmental management in order to improve the state of the environment, reduce risks to human health and improve living conditions. The establishment of management and information systems for creating short-term forecasts of pollution levels can aid the drawing up of appropriate strategies and control. Such information can be used by municipal services in order to minimise negative environmental effects and improve air quality. Objectives The objective of the APIS project is to minimise the negative impact of air pollution on public health by developing a new air pollution management and information system. This new tool will combine different existing meteorological models and risk assessment methods, providing useful information to better control and monitor air quality. The main aim is to provide decision-making bodies and local citizens with necessary information and warnings about air quality and its forecasted impact. This system will provide a toll for controlling air quality and efficient environmental planning. The project will create an information and warning system for the public that includes air pollution, meteorological and bio-meteorological conditions. This objective will be achieved through the design and implementation of an air quality modelling system and a communication system about risks. A support system will also be established for air quality management. Expected results: The project will help to improve air quality and public health by: Enabling a 3-5% reduction in the emission of air pollution; Permitting emission reduction during adverse weather condition; Reducing the number of days on which the limit value is exceeded (by >10% days per year); Applying a pollution and biometeorological forecast system throughout Lower Silesia; Creating an information system for current weather conditions and air quality that can be accessed online by local citizens or at information points; Identifying areas where actions on air quality should be implemented; Reducing air quality-related health risks by warning the population about acute pollution episodes or about harmful meteorological conditions (e.g. heat waves); Providing parameters for the updating of the zoning plan; and Raising public awareness about the impact of pollution.
