甲基叔丁基醚（MTBE）是一种常见的发动机用燃料氧化物 用于控制排放和提高辛烷值的汽车燃料。它比水溶性强 其他燃料成分，不易吸附在土壤等基质上。它可以 通过泄漏的地下燃料储罐和 管道泄漏、城市暴雨径流和降水。它也可以 通过机动船艇排出的废气污染露天水库。 南加州大都会水区调查了六座水库 供应南加州的饮用水。在这些水库上休闲 范围从完全没有到个人船只的高度活动。发现 机动船艇可为供水提供大量MTBE。 包括13个参考文献、表格、图表。

Methyl tertiary butyl ether (MTBE) is a common fuel oxygenate used in motor vehicle fuels to control emissions and boost octane. It is more water-soluble than other fuel constituents and does not adsorb well to substrates such as soil. It can contaminate groundwater supplies through leaking underground fuel storage tanks and pipelines, and through spills, urban storm runoff, and precipitation. It can also contaminate open water reservoirs through exhaust from motorized watercraft. The Metropolitan Water District of Southern California surveyed six reservoirs that supply drinking water in Southern California. Recreation on these reservoirs ranged from none at all to high activity with personal watercraft. It was found that motorized watercraft can contribute a significant amount of MTBE to the water supply. Includes 13 references, tables, figures.
