Determining Air Quality Index of pollutant particles and its Health Impacts

Abstract

This investigation has been conducted to study the environmental problems caused by fine particulate matter air pollution in Baghdad city in Iraq . Date of observation , dust and patients suffer from respiratory and cardiovascular (heart and circulatory system) diseases as effected by particle pollution or particulate matter in the air were obtained , also air quality index combined by the author . The air quality index values of current study were 00 , 40.00 , 50.00 , 50.00 , 51.00 , 51.00 , 68.00 , 75.00, 92.00 and 98.00 % for21/3/2009(clearest day ) , 24/3/2009 , 13/ 3 / 2009 , 30 / 3 / 2009 , 28 / 3 / 2009 , 29 / 3 / 2009 , 22/3/ 2009 , 25/3 / 2009 , 15 /3/ 2009 and 9/3/2009(most dusty day) . The value ranges 0 – 40 % Levels of Health Concern as good and cautionary Statements is none . However , The value ranges 90 – 100 % Levels of Health Concern as Hazardous and cautionary Statements , people with heart or lung disease, older adults, and children should remain indoors and keep activity levels low . Everyone else should avoid physical activity outdoors . The relationship between the dust concentration in the atmosphere as measure of visibility( Y ) and the total number of suffered patients ( X ) could be explained by the following regressing equation :1- Y = 264.7590 X -0.0714 r = 0.6284 From Abn Alnafees Hospital 2 - Y = 136.8317 + 6.2382 X - 1.1165X 2 r = 0.8425 From Al Kindy Hospital 3 - Y = 298.8405 – 30.5272 X r = 0.8127 From Medical City The total number of the patients suffer from respiratory and cardiovascular (heart and circulatory system) diseases visited Abn Alnafees Hospital and Al Kindy Hospital in Baghdad increases with increasing dust concentration in the atmosphere , the relation was highly significant (r = 0.6284 Abn Alnafees r = 0.8425 Al Kindy and r = 0.8127 Medical City) . Patients prone to heart disease may one day be told by physicians to avoid not only fatty foods and smoking but air pollution too.Key words; air quality index , dust , visibility , Levels of Health Concern ,
