 Posted: Fri May 11, 2007 12:13 am Post subject: Is "Yellow Dust" really just pollen? |
 |
|
I have been heeding the warning of the yellow dust season, and when my allergies just started acting up, I thought I was a goner. Then I realized that the "yellow dust" on my plants and whatnot was really pollen.
I remember reading other posts where people said there was both y-dust and pollen in their apartments.
Is there some confusion about this? Are Koreans mistaking one for the other, or is y-dust really scientifically documented? |

| I believe its primarily fine sand carried in off the Gobi (along with im sure all sorts of wonderful pollutants). |

| the thick stuff you see on puddles and cars is probably pollen. the fine dust like stuff that clouds the air is probably yellow dust. If it hurts to breath it is probably the dust |

Asian Dust (also yellow dust, yellow sand, yellow wind, or China dust storms) is a seasonal meteorological phenomenon which affects much of East Asia sporadically during the springtime months. The dust originates in the deserts of Mongolia and northern China and Kazakhstan where high-speed surface winds and intense dust storms kick up dense clouds of fine, dry soil particles. These clouds are then carried eastward by prevailing winds and pass over China, North and South Korea, and Japan, as well as parts of the Russian Far East.

yellow dust can affect your allergies - take a look what it contains.......

An analysis of Asian Dust clouds conducted in China in 2001 showed them to contain high concentrations of silicon (24-32%), aluminium (5.9-7.4%), calcium(6.2-12%), and iron, numerous toxic substances were also present, as it is thought that heavier materials (such as poisonous mercury and cadmium from coal burning) settle out of the clouds closer to the origin.
People further from the source of the dust are more often exposed to nearly invisible, fine dust particles that they can unknowingly inhale deep into their lungs, as coarse dust is too big to be deeply inhaled. After inhalation, it can cause long term scarring of lung tissue as well as induce cancer and lung disease.
Sulphur, (an acid rain component), soot, ash, carbon monoxide, and other toxic pollutants including heavy metals (such as mercury, cadmium, chromium, arsenic, lead, zinc, copper) and other carcinogens, often accompany the dust storms, as well as viruses, bacteria, fungi, pesticides, antibiotics, asbestos, herbicides, plastic ingredients, combustion products as well as hormone mimicking phthalates. Though scientists have known that intercontinental dust plumes can ferry bacteria and viruses, "most people had assumed that the [sun's] ultraviolet light would sterilize these clouds," says microbiologist Dale W. Griffin, also with the USGS in St. Petersburg. "We now find that isn't true." |

The big yellow dust clouds in the end of March, early April, were Gobi desert yellow dust.
But the "yellow dust" that was in the puddles last week was pollen; I think so.
Just a natural part of nature, no need for any warnings to be sent (unless you have pollen allergies). |
