The PM10 priority locations are those near some of the busiest roads in central London where modelling shows that the margin between modelled concentrations and the daily mean PM10 limit value will be very small in 2010. These few locations in central London are therefore most at risk of exceeding the limit value in 2011 if, for example, weather conditions are unfavourable. Should further modelling or monitoring show that other locations are at risk of exceeding the limit values, they will also be treated as priority locations and targeted local measures will be applied at them.
