| The compositions of the MAC-10,a mineral processing reagent,is analyzed by using GC-MS technique.A mass of endocrine disruption compounds,phthalic acid esters(PAEs),are found.This is peculiar in the man-made mineral processing reagent of non-ferrous mines.Quantitative detection shows that there are 59.9 % of PAEs in the tailing waste water.Additionally,PAEs can migrate along with tailing waste water and as a result,making pollutions. |
