Global population growth and urbanization have led to a range of environmental issues, with soil
pollution being a significant concern. Soil, as a critical component of the ecosystem, is highly affected by
pollution, and changes in soil quality can have profound impacts on the environment. Pollutants in the air
eventually settle on the soil, making soil an effective medium for assessing pollution levels. Among
environmental pollutants, heavy metals are particularly significant due to their toxicity, tendency to
bioaccumulate, and persistence in the environment. Monitoring heavy metal concentrations is therefore
crucial. This study aims to determine the pollution levels of nickel (Ni) and cobalt (Co) in the city center
of Trabzon, which has the highest population density in the region. The study involved dividing Trabzon's
city center into sub-regions with varying characteristics, collecting topsoil samples from these areas, and
analyzing them for Ni and Co concentrations. The data were statistically evaluated, was used to model the
data with the kriging interpolation method, resulting in detailed pollution. The results indicate that the
highest concentrations of Ni and Co are generally found in the central areas of the study region, highlighting
that Ni and Co pollution increases with higher levels of human activity.
