Abstract

This article analyzes the environmental impact of modern cars, in particular the amount of harmful substances emitted into the environment by electric cars and internal combustion engine cars, and provides scientific information on the substances that are released from cars in the form of not only gaseous emissions, but also dust particles generated by the mechanical wear of the brake system and tires. At the same time, this article also takes a scientific approach to the wear rates of brake pads and tires, their impact on environmental safety, and the level of dispersion of the microdust generated. Comparative tables have been compiled on the environmental impact of electric cars and vehicles with internal combustion engines, which reflect parameters such as performance, dust emission, and energy consumption. Factors that allow comparing these indicators on the same basis were used. In particular, assessments based on parameters such as carbon emissions, nitrogen oxides, and the amount of toxic particles were also presented. The article provides separate analyses of the amount of dust particles generated by the less frequent use of electric cars compared to brake pads, their physicochemical properties, and the level of environmental pollution. The mechanism of operation of brake pads, a comparison of their various types of dust based on organic, semi-metallic, ceramic, etc., is also presented. The mechanism of dispersion of particles resulting from mechanical friction occurring when a car is moving or braking, and their impact on human health and the environment are also considered.
