EPA primarily curbs particulate air pollution by limiting primary aerosol emissions from diesel exhaust, he notes, so "controlling particles may not be sufficient."

他指出，EPA(美国环保局)主要通过限制柴油车辆排放的初级气溶胶来减少大气颗粒物污染，所以“控制颗粒物可能还不够。”

Prof Kevin McConway, a statistician at the Open University said, based on the findings, if Newcastle were to halve its current particulate air pollution level it would lead to two or three fewer low weight babies out of the total 3, 500 or so born in the city each year.
