Nuclear power stations...simplesFine particulates are also introduced into the environment from tyre wear and brake linings (significant quantities) and from biomass combustion. Coarser particulates predominately come from soil/land erosion and mining. Also if the idea is that electric cars are somehow a panacea , if we were all to convert to them, we would have to bring on stream 100% of the time an awful lot more power generation to cope.
There is very little difference between emissions of all sorts from either modern diesel and petrol Euro 6 compliant engines except of course the much higher C02 from petrol engines. A change to electric powered vehicles is just moving the emissions from the tailpipe to the power stations. Be aware that all wind turbines, apart from the dreadful environmental damage they do to local environments, they must be continuously backed up by fossil fueled power stations at all times due to the dreadful intermittency of wind.
