Abstract
The study analyses the results of laboratory samples of the content of eight heavy metals in gross and mobile forms in the soil cover of Rivne, which were taken at 5 test sites in different districts of the city.
To assess the level of soil contamination, it has been calculated the total contamination indices (Zc) for both forms of heavy metals.
Interpolated surfaces were built to visualise the city’s heavy metal contaminated areas.
For the gross form of heavy metals, it was found that most of the sampling sites (52 %) correspond to the “Moderately dangerous” pollution category, and 34 % of the samples correspond to the “Dangerous” category.
For the mobile form of heavy metals, it was found that the vast majority of the territory is within the “Permissible” pollution category – 74 % of samples, 18 % of samples correspond to the “Dangerous” category.
The highest levels of heavy metal contamination in the soil cover of Rivne are at the Northern, the North-Eastern and the South-Western Industrial Zones of the city.
