Which substance is commonly found in hazardous wastes from vehicle maintenance?

Heavy metals are commonly found in hazardous wastes from vehicle maintenance due to the various components and fluids used in automobiles. This includes materials such as batteries, oil, brake pads, and other vehicle parts that may contain lead, cadmium, mercury, and chromium. These metals can leach into the environment if not disposed of properly, posing significant risks to human health and ecological systems.

Pesticides, food waste, and glass particles, while they can be hazardous or problematic in different contexts, are not typically associated with the waste generated specifically from vehicle maintenance. Pesticides are more related to agricultural practices, food waste concerns nutrition and disposal patterns in households and restaurants, and glass particles are generally associated with packaging or residential waste rather than the specific industrial context of vehicle maintenance.
