A blue-ribbon scientific panel has waved a yellow flag in front of a rapidly expanding number of products containing nanomaterials, cautioning that the tiny substances might be able to penetrate cells and interfere with biological processes.
The warning is contained in a report from the Council of Canadian Academies that will be released publicly today. It is one of the most authoritative to date in this country about the risks of engineered nanomaterials, which companies are adding to products ranging from sunscreens to diesel fuels.
Their lorry, called "the Bio-truck", runs on a fuel created by a Lancashire-based producer, Ecotec, which has developed a process to turn chocolate misshapes into biodiesel.
Most of the chocolate would otherwise end up in landfill.
The layer of peat and the high acidity of the marshy lake had created a kind of protective cocoon around the tank, sealing it off from corrosion and preserving it through 56 years under water. To the team’s delight, nearly every part and mechanism proved to be in perfect working order after cleaning. The fuel tanks were found to be empty, confirming the assumption that the tank had been abandoned and dumped in the lake due to shortage of fuel. The diesel engine had leaked no oil. Astoundingly, without replacing any spare part, the team managed to start up the Diesel engine.
