11. MTBE in petrol as a substitute for lead
نویسنده
چکیده
The goal of this case study is to examine how foresight, embodied in the precautionary principle, can lead to robust and flexible decisions that meet the needs of the present, but that can be adapted to meet the changing needs of the future. Recently there has been much debate over the use of methyl tert-butyl ether (MTBE) in petrol. Concerns in particular over the potential for contamination of groundwater supplies have prompted regulative authorities in western nations to reassess the risks associated with the use of MTBE.
