An air monitoring station at Stockton measures PM10, PM2.5, NH3, NO2, NOx and has been operational for 8 months. There have been 20 failures of the PM10 50 ug/m3 criteria and 1 failure of PM2.5 25 ug/m3 advisory. Is this a cause for concern. 

Given the health damage caused by PM10 and PM 2.5s, is it satisfactory for our leaders to aim for only a small reduction to exposure, such as 10% or 20%? Should some sources of particles such as the burning of wood for heating/BBQs, be phased out altogether?

e.g. diesel used in extracting and transporting coal
