The purpose of this study is to identify and characterize individual sources of pollutants such as PM₁₀, SO₂, NO_x, and CO in the urban area in Karadeniz (Turkey) using the bivariate polar plots method. In addition, the relationship between the meteorological conditions and the pollutants was determined based on correlation analysis in the region. Bivariate polar plots are a graphical method used to demonstrate the dependence of pollutant concentrations on wind direction measured at stations. Thanks to these graphics, resource types and properties can be determined. Wind flow and pollution data were used to provide information on wind and pollutant interactions in the study area. As a result of the study, it was founded that the main source of pollutants is intensive anthropogenic activities such as urban, street traffic, agricultural activities, and natural resources. It has been concluded that the highway in the region is not an important source of pollutants. In addition, the pollutant relations were examined with meteorological data, and it was discovered that temperature and relative humidity were effective for all pollutants.

本研究的目的是识别和表征污染物的各个来源，例如 PM ₁₀ , SO ₂ , NO _x, 和使用二元极坐标图方法的卡拉德尼兹（土耳其）市区的 CO。此外，根据该地区的相关性分析，确定了气象条件与污染物之间的关系。双变量极坐标图是一种图形方法，用于证明污染物浓度对站点测量的风向的依赖性。由于这些图形，可以确定资源类型和属性。风流和污染数据用于提供研究区风和污染物相互作用的信息。研究结果表明，污染物的主要来源是密集的人为活动，如城市、街道交通、农业活动和自然资源。结论是该地区的高速公路不是重要的污染物来源。此外，通过气象数据检验污染物关系，发现温度和相对湿度对所有污染物均有效。
