Composition of crystals in soils and atmospheric dust and their source-indicating ignificance:A case study of Changsha,Xiangtan and Zhuzhou cities,Hunan,China;

Based on the atmospheric dust experiment, researches the contaminant air exchange caused by the temperature difference while opening the door of isolation wards.

Experimentally studies the relation of the pressure difference and leakage rate of contaminations separately by atmospheric dust method and experimental culture method.

Characteristics of saturated hydrocarbons in dustfall from a coal-mining area, Henan, China;

The Research about the Distribution and Modality Analysis of the Chromium in the Dustfall on the Campus of ChengDu Univerisity of Technology;

In this study a set of environmental magnetic parameters(χlf,χfd%,χarm,SIRM,HIRM,SOFT and back field IRM) were measured on the monthly-collected dustfall samples(KLD),which were collected during April 1997 to May 2000 and November 2004 to October 2005 at Lanzhou University campus.

By optimizing extracting method,heating procedure,chromatographic temperature,19 polycyclic aromatic hydrocarbons in airborne particulate are detected by gas chromatography/mass spectrometry(GC/MS) with quickness and good sensitiveness.

In this work, samples of airborne particulates,vent gas and smog dust during heating and non-heating seasons were collected in the urban and suburban areas of Lanzhou.
