Fig. 1From: Effects of water-soluble components of atmospheric particulates from rare earth mining areas in China on lung cancer cell cycleContent of metallic elements in WSPM10 and WSPM2.5. The abscissa represents the element species, while the ordinate represents the mass concentrations (μg/g) of the element (in log scale) in WSPM10 or WSPM2.5. The metallic elements of the samples were determined using inductively coupled plasma-atomic emission spectrometry. The power was 1.4 KW, the carrier gas flow rate was 1.0 L/min, the coolant flow was 15 L/min, the auxiliary flow was 1.0 L/min, and the pump speed was 1.5 L/minBack to article page
