Abstract
Notice of Retraction
After careful and considered review of the content of this paper by a duly constituted expert committee, this paper has been found to be in violation of IEEE´s Publication Principles.
We hereby retract the content of this paper. Reasonable effort should be made to remove all past references to this paper.
The presenting author of this paper has the option to appeal this decision by contacting TPII@ieee.org.
Based on Negritti (medium-big-volume sampler) and MiniVol (mini-medium-volume sampler) two instruments, intensive samplings on inhalable particulate matter (PM10) in Pingdingshan city have been conducted, the mass concentrations of PM10 was weighted, and the content of parts of heavy metals of PM10 was tested by ICP-MS in this paper. The relationship between the concentration of PM10 and the meteorological condition was discussed. The experiments indicate that the mass concentrations variation of PM10 and the wind speeds had an inverse ratio of correlation, and the mass concentrations variation of PM10 and the humidity had a positive ratio of correlation. The contamination extent of heavy metals in inhalational particles is rather serious in Pingdingshan city. The pollution of Pb, Zn and Cu in the collected samples is the most serious, and the enrichment fact of Pb, Zn, Cu, Fe and Cd is 825.3, 633.5, 63.7, 14.6 and 13.1 respectively. This indicates that the contamination of heavy metals correlate with vehicular exhaust and coal combustion.
