- Аннотация: The study is aimed to assess the composition and properties of solid material supply to the environment from vehicles. The study was conducted in the area of an ice race track located on the surface of a lake located at a significant distance from the stationary sources of pollution. The sampling was conducted on February 27, 2019. The samples of snow cover and ice were collected at the roadside of the track and at a distance of > 10 m from the ice race track in the winter period. The ice race track was located on Lake Baltym (north of Ekaterinburg, Sverdlovsk region, Russia). The samples of snow were melted. The solid material of the samples was separated with filter paper and dried. The particles were selected manually and photographed using an optical microscope, and then they were analyzed with a scanning electron microscope. The origin of the selected particles was determined. The particles were classified into three types: fragments of car tires (5 particles per 1 L of meltwater in the curb area of the ice race track),fragments of cast-iron brake discs (2 particles per 1 L of meltwater),fragments of a composite material of car brake pads.The approximate amount of solid material supply to the lake from the ice race track during one season was estimated at the level of 40 mg/L.
