The use of a mass balance equation assists in clarifying the contribution of automotive-emitted lead to the regional and global problems of the distribution of this element, by taking into account the physicochemical transformation processes operating on the lead during its transport along the various environmental pathways. The technical factors which govern the emission of such lead from automobile engines and which affect its subsequent dispersion through the environment are described.
通过考虑铅在沿各种环境路径传输过程中发生的物理化学转化过程，质量平衡方程的使用有助于阐明汽车排放的铅对该元素区域和全球分布问题的影响。文中描述了控制汽车发动机此类铅排放以及影响其随后在环境中扩散的技术因素。
