| Abstract: | To understand the source of PM10 collected in Chengguan District of Lanzhou,Gansu Province in winter and spring,inductively coupled plasma-mass spectrometry(ICP-MS) was used to study the concentrations of whole and water soluble fraction elements including Ti,V,Cr,Cd,Mn,Cu,Zn,As,Se,Sb,Pb,Ba,Mg,Al and Fe in PM10.Results showed that total concentrations of these whole and water soluble fraction elements in PM10 show a decreasing trend through winter and spring.Except some crustal elements such as Al and Mg,th... |
