Abstract |
: |
Kingdom of Saudi Arabia has established the terms of industrial development in the industrial cities of Jubail and Yanbu on the highest level of advanced technology especially industries of the hydrocarbons and their derivatives. However, industrial development is a double edged weapon. The development in such industries has negative impact on the level of air pollution, which reflected respectively negatively on public health. One of the most serious impacts of industrial pollution is indoor pollution which occurs because of poor building design, poor ventilation, or external air pollutants, especially if the housing is located in an industrial environment. These pollutants are seeping into the buildings through vents, windows, and skylights.
Therefore this study aimed to evaluate the association between Air Pollution and lung function in Yanbu Industrial city in the long run in children aged (10-11) years. For this purpose, data was obtained from the Department of Environmental Protection in Yanbu Industrial City concerning the concentration of some air pollutants such as (CO, SO2, NO2, O3, H2S, THC, PM10) for the years (2003, 2004, and 2005). In addition, pulmonary function tests of children have been checked up using (Spirometer) in May and December 2006.
A public health survey for the children is included in the study. The survey covers general information such as age, height, previous place of residence, medical history of the family, and the physical condition of the children living in the city. Medical records for children resident in the city and outside it have been considered as well. The results of the survey indicate that pollutants’ concentrations, either in monthly or yearly basis, didn’t exceed the permissible limits of the standards of air quality in Yanbu Industrial City during the period covered by the study.
Besides, the results show that there is statistically significant relationship between the results of lung function tests and time of year (i.e. summer and winter). 19.5% of the sample showed restrictive pulmonary function testes in summer whereas 27% of the sample had restrictive pulmonary function testes in winter.
The results of the research highlight that there is no notable difference between the mean period of residence in Yanbu Industrial city and lung function tests concerning the target sample. Air analysis data reveals that the average air concentration of carbon monoxide, hydrocarbons, nitrogen monoxide and nitrogen dioxide, measured per hour, is less than the standards set for the city. It also indicates the highest concentration of ozone, hydrogen sulfide, sulfur dioxide, and nitrogen dioxide per hour exceeds the city's criteria once during 2003, 2005 and twice during 2004. The study illustrates that the highest daily concentration compared to the annual average concentration of respirable particulates of Yanbu industrial city exceeds the permissible limits during the period of the study.
In 2006, climate statistics pointed out that the temperature was between (45.9 to 12.5 degrees Celsius), the relative humidity ranges from (100.0 - 0.5%) and the average wind speed was only (16.8 m / s).
The analysis of the medical records of children living in Yanbu Industrial City clears that there is not direct relationship between the number of attendants at the clinics and the concentration of air pollutants. As a matter of fact, the study records that chest clinic has the least number of visitors during 2000 up to 2005, and during May and December 2005, for residents in Yanbu industrial city or outside it as well. |
