Interest has arisen in heavy-metal contamination of the environment, mostly because of potential hazards to the health of animals and human (directly and/or indirectly). High levels of heavy metals in soil, plants, and the atmosphere are often related to industries, highways , chemical dumping, impure chemical fertilizers, and pesticides containing metals. An important source of heavy metals, especially lead, is from the combustion of leaded gasoline used for transportation. Other heavy metals associated with transportation include nickel, which is also added to gasoline and is contained in engine parts, zinc, and cadmium from tires, lubricating oils, and galvanized parts such as fuel tanks.
人们对环境中的重金属污染越来越关注，主要是因为其对动物和人类健康存在潜在危害（直接和/或间接）。土壤、植物和大气中的高含量重金属通常与工业、公路、化学废弃物倾倒、不纯的化肥以及含金属的农药有关。重金属的一个重要来源，尤其是铅，来自用于交通运输的含铅汽油的燃烧。与交通运输相关的其他重金属包括镍，它也被添加到汽油中，并存在于发动机部件中，还有来自轮胎、润滑油和诸如燃料箱等镀锌部件中的锌和镉。
