Coal is a fossil fuel that can have negative impacts on the environment and human health during
extraction, transportation, and burning. In this study, samples were collected from eight boreholes in
the Tekirdağ-Malkara coalfield and the major-trace element analysis was performed. Lithology data
obtained from boreholes constitute well logs. Interpolation forms the basis of log correlation. The
study aimed to determine the local areas that may pose a risk after selecting the interpolation method
that provides the most accurate results directly in the study area. Among the elements, those that may
cause environmental and human health problems were selected and divided into four groups according
to their hazard class. The distributions in the whole field were estimated by Kriging and Inverse
Distance Wighting (IDW) interpolation methods. These two interpolation methods were evaluated
with a selected test probe and the Kriging method was determined to provide the most accurate
results. With this method, the accuracy of results obtained with the elements in the hazard class were
as follows: Hg and Cr 100%, Se 98.86%, Cd 75%, As 66.2%. After determining Kriging as the
method to be applied, a re-classification analysis was carried out, and estimates made in the field were
compared with coal from Turkey, the US, China, and the average upper continental crust. As a result
of this comparison, the elements with the highest rate of distribution in all averages were determined
as Be, Cu, V, and the elements with the lowest distribution rate were Mn, Mo, P, Sb.
