Robertonline Posted October 9, 2017 Share Posted October 9, 2017 Hi to all. I would like to know if you noticed anything strange in the research for air pollution, in the stats, when it comes to PM 10 and PM 2,5 particles. In one web site where there are important statistical data the PM 10 did not appear in the spredsheet. There was only the PM 2,5 being shown. There are also important differences along the years from country to country. Quote Link to comment Share on other sites More sharing options...
