This study evaluate the quality of air in the central mosque of Prophet Mohammad's northern city of Medina, "district of the goods." During the period of the 5-9 until 30/12 to 1426 AH 10-8 / 2005 m until 30/1/2006. As measured by the carbon monoxide (CO), sulfur dioxide (SO2), nitrogen oxides (NOX) and ozone (O3), methane (CH4) and total hydrocarbons (THC ) and the wind speed and direction and concentrations were
The first record of the least carbon dioxide concentration (0.092PPM) at the date and the highest concentration (15.590PPM) at the date and the averages (1.18-5PPM) on, respectively,
Sulfur dioxide concentration recorded the least (0.001PPM) several times and the highest concentration (0.072PPM) at the date and the average (0.004-0.023PPM) on, respectively,
Nitrogen oxides scored less emphasis (0.008PPM) several times and the highest concentration (0.588PPM) at the date and the average (0.004-0.023PPM) on, respectively,
Less concentration of ozone record (0.008PPM) several times and the highest concentration (0.588PPM) at the date and the average (0.004-0.023PPM) on, respectively,
Less concentration of methane record (0.008PPM) several times and the highest concentration (0.588PPM) at the date and the average (0.004-0.023PPM) on, respectively,
Scored lower concentration of hydrocarbons (0.008PPM) several times and the highest concentration (0.588PPM) at the date and the average (0.004-0.023PPM) on, respectively,
Wind speed and direction, ranging from on average, respectively,
And the direction of prevailing winds
It has already concluded that the region's air quality monitoring, which was not up to the dangerous or bad in the current period and found that concentrations of carbon monoxide, sulfur dioxide, nitrogen dioxide and ozone did not exceed the permissible limits of locally and globally .. But this does not mean the absence of high concentrations in regions other issue related to weather conditions and the movement of contaminants. The expected decline in air quality, especially in light of ongoing developments and increasing the facilities and residential buildings within the central area of high and increasing density of population and industrial and commercial activities in the city of Medina in general. |
