EMISSION INVENTORY OF TOXIC ATMOSPHERIC POLLUTANTS IN BARAKALDO TOWNSHIP (SPAIN) AND ON ITS OUTSKIRTS

摘要

The aim of the Study has been the Emission Inventory of minor atmospheric pollutants with toxic character in Barakaldo Township and in the area around it. This study has been conceived as a link within a global work line to middle - long term. Figure 1 illustrates the work plan designed by the Town Council of Barakaldo and LABEIN, concerning the study of toxic atmospheric pollutants. In this study, the main minor pollutants derived from industrial activity, traffic and combustion processes in the residential and services sectors have been identified. When it has been possible, the emission rates have also been estimated. To estimate the emission rates of these pollutants, emission factors (EPA, Corine, PARCOM/ATMOS, etc.) and emission measurements in stack has been used. The geographical area studied (rectangle of 9 Km X 14 Km) has been the Barakaldo Township and the areas around Barakaldo with potential influence on the air quality of the town, due to the presence of polluter industrial activities. Figure 2 shows the geographical area of study. The great number and type of pollutants in the study area has forced to focus on the work in the most toxic and hazardous pollutants. The selection of these pollutants has been based on the Guidelines of Air Quality developed by the World Health Organization for Europe. This study has been the first step of a Global Project to evaluate the air quality of the area subject to study and to establish the relationship cause-effect between the air pollution in Barakaldo and the diseases observed in the town population. Finally, the Global Study will be useful to develop programs in order to control and reduce the emission of this type of pollutants.
