pollutants
Not to mention highly toxic and polluting MTBE [methyl tertiary butyl ether] and well known carcinogen, Benzene. The pollutants in modern low NOx and particulate diesels running ultra low sulphur diesel almost pales into insignificance in comparison. The exhaust from these diesel engines is almost odourless, as you know.
It is estimated that two million out of six million fuel station tanks in the US leak petrol into the ground. 1500 public American water supplies are polluted with MTBE and Benzene. It will cost at least $141 billion Dollars to clean up. Normally the polluter would pay but even considering the clean alternative to MTBE, which was available from the beginning, Big Oil has exerted pressure on the powers that be and 'persuaded' [is that the same as 'bribed'?] them that the American taxpayer should pay for their mess.
All this sound so familiar to those who knew about the lead scandal and how unnecessary, indeed criminal, was its inclusion combined with the brainwashing of citizens to accept, even demand, its continued and totally unnecessary use.
