To Study The Impact Of Dust On The Health Of Residents In XinJiang Hetian

Objective To study the impact of dust on the health of residents in XinJiang Hetian. Methods:To analyse the general air pollution condition by atmospheric particulate matter PM10 and the general population health survey about the blowing dust process occurred on June 6th 2009 in Hetian. Then to explore the impact of PM10 to the air quality and the health of the residents in Hetian. Results:There were occurred only 253 days that the air quality achieved national level 3 standards in 2008 and 2009.Dust weather was frequent in spring(March,April,May) and summer(June,July,August),and the hourly PM10 average concentrations were irregular.The daily average concentrations of PM10 on dust weather were higher non-dust weather days and the number would go to the maximum on the days when dust storms, blowing dust and floating dust.The blowing dust weather could cause the symptoms of dry eyes,eyes with foreign body sensation, dry nasal cavity, rhinostegnosis, and dry and pruritic pharynx, throats hurt and dry lip. The incidence of nasal and pharyngeal symptoms had the same trend with the PM10 concentrations, and it increased when age decreased in the children group, and the contrary was the case in the adult group.PMio concentration was positively correlated with some symptoms and children are more sensitive to dust pollution. Conclusions:(1)The residents of Hetian lived in high concentrations of atmospheric particulates average PM10 for a long time. (2)Sandstrom weather could lead to the rise of atmospheric PM10 readings. The health effects occured mainly on the day when the incidence happened, it's an acute effect and the incidence of crowd malaise symptoms would significantly decrease after the dust weather. It suggested that PM10 concentrations may related to the occurrence of some symptoms.
