The role of pesticides in modern agriculture is not in doubt; the continuous improvement of drugs and technologies for their use reduces the possibility of environmental pollution and their accumulation in manufactured products. The purpose of the research is to assess the pollution of the soil cover of agricultural land with residual amounts of pesticides in the Samara region conditions. Tasks: to analyze the content of insectoacaricides and herbicides residual amounts in the soil in the spring and autumn; - establish patterns of residual pesticides migration along the soil profile. As a result of studies conducted in 2016-2018. it was found that the content of total DDT related to the first hazard class in the studied samples decreases, a similar situation is observed for organochlorine insectoacaricides HCH and HCB, their residual amounts were found in the soil in the autumn and spring periods of 2016. Residual quantities of the organophosphorus insect metacosacaricide were detected annually (the exception was the autumn period of 2017). Regarding the content of residual amounts of herbicides in the soil (2, 4-D, dalapon, simazine, atrazine, promethrin, trifluralin, THAN), it can be noted that during the years of research their content was mainly reduced. A study of the pesticides vertical migration showed that the content of their residual amounts in the soil increases with depth, reaching a maximum at a depth of 1.0-1.6 m.

Mixed office paper (MOP) pulp without deinking with an ash content of 18.1 ± 1.5% was used as raw material to produce nanofiller-paper. The MOP pulp with filler was mechanically fibrillated using a laboratory stone grinder. Scanning electron microscope imaging revealed that the ground filler particles were wrapped by cellulose nanofibrils (CNFs), which substantially improved the incorporation of filler into the CNF matrix. Sheets made of this CNF matrix were densified due to improved bonding. Specific tensile strength and modulus of the nanofiller-paper with 60-min grinding reached 48.4 kN·m/kg and 8.1 MN·m/kg, respectively, approximately 250% and 200% of the respective values of the paper made of unground MOP pulp. Mechanical grinding duration did not affect the thermal stability of the nanofiller-paper.
