A kutatási téma leírása:
Conventional sources of primary particulate matter such as engine exhausts and industrial processes are reasonably well regulated by now and, except for a few "super" emitters such as the existing stock of coal fired heating appliances, contribute relatively little to urban air pollution. In winter, however, when most breaches of air quality standards (and in particular PM limit values) occur, burning of solid waste in households represents a substantial source of hazardous particulate matter not only in cities but also in small settlements. It is estimated by policy makers that thousands of tons of plastic, clothing, combustible construction waste, paints and litter may end up in residential stoves. Waste-burning generates extremely large amounts of PM emissions in residential areas, exposing millions of people to very high concentrations of extremely hazardous particulate matter, even before the effects of the associated gaseous emissions are taken into account. Soot particles loaded with lead, mercury, chromium, barium, cadmium and other toxic metals, pesticides, phthalates, isocyanates and polycyclic aromatic hydrocarbons are emitted in large amounts causing adverse acute and chronic health effects in human beings and in particular sensitive groups in the population.
The objective of the planned research is to estimate the source contribution of residential solid waste burning to particulate pollution in Central and Eastern Europe. Based on the data collected in waste burning experiments performed under controlled conditions and/or literature data the chemical and physical properties of the emitted particles from waste burning will be investigated. Aerosol samples will be collected in Hungary and Romania and their chemical composition will be determined by off-line instruments. Based on the amount of the tracer compounds (characteristic for burning of plastics) present in the samples collected at the two stations the contribution of waste burning to the particulate pollution will be determined. In addition to the filter based off-line measurements a mobile platform equipped with a fast-response real-time instrumentation (optical instruments and PM monitors) will also be applied to monitor the spatiotemporal variation of the so called super-emitters around the sampling sites in Hungary.
