Atmospheric movement of microorganisms in clouds of desert dust and implications for human health.

Human Health Risk Assessment of Cadmium Exposure in Dry Deposition of Atmospheric Dust (Uncertainty Analysis)

 Background and purpose: The atmospheric suspended particulate matter is a major route of human exposure to different kinds of environmental pollutants especially toxic heavy metals. The aim of this study was to assess the carcinogenic and non-carcinogenic risk of cadmium in dry deposition of atmospheric dust in Qazvin, Iran. Materials and methods: Glass traps were used for sampling dry atmosp...

Reducing industrial dust pollution by Ash tree Fraxinus excelsior in urban green belt

Heavy metal pollutionis one of the largest problems in the Environment and human being. In industrial and urban areas trees can give better quantifications for pollutant concentrations and atmospheric deposition than non-biological samples. In order to know ability of Fraxinus excelsior­ (Ash tree) to reduce the concentrations of heavy metals and compared with the concentration of thes...

Effects of atmospheric dust deposition on leaf chlorophyll fluorescence parameters of cow-tail shrubs (Smirnovia iranica) in the desert regions of Kashan, Iran

Evaluation of heavy metals from desert dust in rangeland ecosystems of Khuzestan province

Extended abstract 1- Introduction Desert dust is formed under the influence of special weather and environmental conditions in desert areas and enters the atmosphere. Local hurricanes caused by surface air instability, passing through dry deserts, remove silt and sand particles from the surface and enter the atmosphere. Desert dust physically, in addition to its ecological effects such as lun...

Bioassessment of Heavy Metals in Wheat Crop from Soil and Dust in a Coal Mining Area

Coal mining and related industry can increase heavy metals (HMs) concentrations in soil, atmosphere and wheat, thereby posing metal-associated human health risk via food ingestion.  In this study, 58 samples of soil, wheat, and dust were collected from Xuzhou coal mine eastern China, six kinds of HMs Pb, Cd, Cu, Zn, As and Cr were studied for their spatial distribution in wheat, enrichment in d...
