“…In turn, Diatta and Grzebisz (2011) concentrated on the grain fraction \ 1 mm when analysing the quantity of metals the visitors of the urban parks of Poznań (Poland) are exposed to. The grain fractions obtained using the set of sieves 2, 0.250 and 0.125 mm were separated when studying (Valskys et al 2016) the material of the playing grounds of Vilnius (Lithuania).…”

Contents of As, Cd, Co, Cr, Cu, Ni, Pb and Zn were determined in the material collected in sandboxes of seven spa resorts located in S Poland (CCE) and their results used to establish a health risk of children. After sieving out grains [ 2 mm, the bulk samples were quantitatively separated into four grain fractions: 2000-1000, 1000-200, 200-63 and \ 63 lm. In each of them were determined: the mineral composition, the total contents of the elements, and the distribution of the elements among the fractions distribution factor. In the bulk material \ 2 mm, the totals of the elements are 5-64 times lower than in the finest fractions (\ 63 lm). Considering that the finest fractions are enriched in clay minerals such as clinochlore, illite and kaolinite, which can adsorb and desorb metals, this material is most dangerous for children, staying both permanently and temporarily in the spas. The total health risks HI resulting from non-carcinogenic elements present in the fractions \ 63 lm are 1.26 and 0.94, for the children-residents 3 and 6 years old, respectively. The figures are disturbing as one of them exceeds and the other is close to a permissible limit of 1. The highest contribution (93.4%) into the total HI is caused by inadvertent swallowing the soil ''dirt'': the ingestion path HQ ing for the 3 years old residents is 1.17, and for the 6-year olds 0.88. With respect to the elements, the highest is the risk resulting from Pb: HQ in values of the residents are 4.71E-01 and 3.54E-01 for the 3-year olds and the 6-year olds. Slightly lower are the HQ ing values calculated for both age groups: in the case of Cr-3.12E-01 and 2.34E-01 and As-2.92E-01 and 2.19E-01). The dermal path (HQ dermal ) contributes to the total HI much less as it equals 6.5%, while the contribution of the inhalation path (HQ inhal ) is considerably the lowest and equals only 0.1%. The Risk indexes determined in the case of cancerogenic components for both age groups of the spa residents are lower than the permissible limit 10E-5 and equal 6.48E-06 and 9.72E-06, respectively. Considering the children that only visit the spas, all the calculated indexes, i.e., HI and Risk, are significantly lower than those determined for the children-residents.

Introduction. Heavy metal pollution of soils in urban areas is a severe problem in many regions of Russia and other countries. The higher concentrations of heavy metals in playground soils represent a severe threat to children’s health. The lack of legislatively approved decisions on periodic monitoring of soil contamination in residential areas and on remediation measures does not ensure a favourable ecological situation in the urban environment. Materials and methods. The mass spectrometry method was used to analyse the gross content of heavy metals and arsenic in playground soils in residential areas of the Industrialny district of Perm in 2019. Results. The assessment of soil contamination with heavy metals and arsenic in the soils of playgrounds of residential areas of the Industrialny district of Perm indicated their unsatisfactory quality. The concentration of arsenic in the soil exceeded the MPC by up to 4.6 times, zinc-2.6 times; nickel-3.5 times; cadmium-1.7 times; copper-1.5 times. The total indicator of contamination of Zс and Zст of the soil corresponds to the permissible level. The level of soil contamination with heavy metals ranges from “low” to “moderate” based on the indicator of potential environmental risk. Limitations. The limitations of the study are related to the small number of soil samples on the territory of playgrounds and one-time sampling, which limits the interpretation of the data obtained to determine trends in soil pollution, as well as the absence of identified patterns of contaminants in soils from different sources of their inflow. Conclusion. The results suggest that it is necessary to monitor soil contamination in residential areas and implement timely remediation measures; it is necessary to make decisions at the legislative level on the soil quality management in residential areas to ensure a favourable ecological environment, taking into account domestic and foreign experience.
