Abstract This study investigates the impact of platinum released from vehicle catalytic converters on human health and environmental pollution. Population density in urban areas, urbanization culture, the increase in vehicles used for transporting commercial goods or public transportation, the construction of industrial plants, and production activities have led to air, soil, and water pollution, as well as a rise in disease incidence. Platinum is used as a catalyst in the chemical industry and in vehicle catalytic converters to reduce air pollution. However, after aging-typically after about four years-these converters deteriorate, and their components are released into the environment through exhaust gases, posing a threat to human health and ecosystems. Accordingly, this article examines the effects of platinum released from catalytic converters on human health and the environment. The results of this study indicate that platinum in the air dissolves through rain, snow, or water and may enter the human food chain, leading to respiratory disorders and even cancer. Therefore, to prevent the negative effects of platinum on humans and the pollution of the environment, suggestions for the development of catalytic converter technologies have been proposed. This article highlights the urgent need for better management of used and damaged catalytic converters and further research on the adverse effects of platinum on human health and the environment Keywords: Catalytic Converter, Environment, Ecosystem, Human Health, Platinum, Motor Vehicles
