Web10 nov. 2016 · MTBE was initially used for the recovery of bacterial organic acids and lipids from different eukaryotic samples [25, 26]. The main advantage of using MTBE is the fact that it has a severely decreased density (0.74 g cm −3) compared to chloroform (1.48 g cm −3), which not only leads to an inversion of the methanol and the MTBE phases ... Websources used for drinking water had concentrations that ranged from 1 to 5 µg/L. After remedia-tion, half of the sites had levels below 0.1 µg/L (Environment Canada, 2003). The use of MTBE in gasoline has been more widespread and of longer duration in the United States than in Canada; hence, there are more data available from the United States.
