Is AdBlue harmful to the environment? Is it dangerous to handle?

AdBlue is not classified as a dangerous substance or as dangerous cargo during transport. If AdBlue is spilled by accident, the only environmental impact is that it contributes to eutrophication since AdBlue is a nutrient. AdBlue is a low-toxicity substance and has no known chronic health risks. It is not flammable or explosive. There is no risk in case of collision since AdBlue is a stable solution and not sensitive to thrust.
