Determination of Local Status and Trend Views of Air Pollution in Turkey in the Context of National Air Quality Monitoring

Air quality is one of the most important factors affecting human health and effectiveness. In determining the air quality through air pollutant variables considered, regular observations are performed and the data are stored in databases and disseminated in Turkey. In addition to any immediate evaluation of air quality, unfolding long-term statistical views and trends play an important role in the solution of quality problems. In this study, variables compiled from the air quality monitoring stations were examined by statistical approaches within the individual contexts of observation stations, seasonal trend analysis were performed and it was aimed to reveal hot spots that require further attention. When the findings are examined with respect to the investigated periods, general decreases in the average values of PM10 at the scale of Turkey, against relative increases in some provinces, and again decreases in SO2 in a wider scale, excluding the central and eastern parts of the Black Sea region, east Mediterranean and some parts in Aegean, were basically identified. As a result of the trend analysis, the trend views appeared to differ at the stations level and the need for more detailed analysis was revealed especially in the areas with negative outlook
