spatial and temporal distribution of heavy metals concentration in atmospheric dust in kerman city
introduction atmosphere health is an important environmental issue and air pollution is not a local problem in a given area of the world. particles produced by either humans or the nature enter the atmosphere and return the earth’s surface at local, regional, or global scales after physico-chemical interactions. according to the reports by who, each year 2.4 million people lose their lives worl...
متن کاملMigration of interplanetary dust.
We numerically investigate the migration of dust particles with initial orbits close to those of the numbered asteroids, observed trans-Neptunian objects, and comet Encke. The fraction of silicate asteroidal particles that collided with the Earth during their lifetime varied from 11% for 100 micron particles to 0.008% for 1 micron particles. Almost all asteroidal particles with diameter d >/= 4...
متن کاملInterplanetary Dust Community
Imagine a box filled with particles from hundreds of thousands of small bodies throughout the solar system, including asteroids, comets, Trojans, Centaurs, KBOs and even from other stars. Each particle contains information about the object from which it came and the space environment through which it has traveled. Largely collected near the Earth’s orbit and on the Earth itself, this box of par...
متن کاملIon Bombardment of Interplanetary Dust
The recent discovery of ion tracks in interplanetary dust and the increasing evidence for carbon and carburized materials in these objects are strongly suggestive that chemical processing by energetic charged-particle bombardment has occurred during the dust lifetimes. The track density gives a measure of the total ion fluence experienced by the grains. We use this information and laboratory da...
متن کاملEffect of Atmospheric Dust on Interannual Variability in the Martian
Mars Observer Camera (MOC) observations from Mars Global surveyor (MGS) revealed that the Residual South Polar Cap (RSPC) consists of several units that show evidence of deposition and erosion with characteristic times on the order of ~ 100 years [1]. These authors suggested that significant changes observed in the RSPC between MY 9, when Mariner 9 observed the cap,, and MY 12, observed by Viki...
