Opis:
This paper summarizes the author's previous studies on the sorption of hydrocarbons in sandy soils. Completed several independent series of measurements for various models of soil. There were used unleaded petrol and diesel fuel as petroleum products. A large amount of collected information allows you to draw some interesting conclusions, which may be the basis for generalizations. The detected regularity can afford to develop a several models that can be successfully used to describe the intensity of hydrocarbon sorption processes in soils. These processes have a significant impact on the hydrocarbon migration in the soil by reducing the pollution zone and extending the time of migration. Inaccurate description of the magnitude sorption capacity will lead to large differences between the actual scenario of hydrocarbon migration in soil and its numerical simulation.

Opis:
Contamination of surface and groundwater by neonicotinoids is a global problem and requires comprehensive action by individual countries in order to identify in detail the processes affecting the transport of these pesticides, their properties, and their harmfulness to the environment. The aim of this study was to assess the transport (expressed by sorption parameters) of selected neonicotinoids in the aquatic environment, using batch tests. Tests were carried out for acetamiprid individually and a mixture of five neonicotinoids (acetamiprid, clothianidin, imidacloprid, thiacloprid, and thiamethoxam), for three different aquifer materials and quartz sand. Based on the obtained values of the sorption parameters, the greatest sorption of neonicotinoids was observed on soil with the highest content of organic matter and clay minerals content, while no sorption of these pesticides was observed on quartz sand. In addition, it was noticed that individual neonicotinoids undergo sorption to a different degree — thiacloprid was the most sorbed (R-value in the range 3.13–26.03), while thiamethoxam was the least (R-value in the range 1.89–8.41).
