* There is no standard available for Methane (CH4) & Total Hydrocarbon (THC).
So with our experience of monitoring CH4 & THC in ambient air at different locations of Jeddah city under normal conditions The average 3 hours concentration values for Methane (CH4) & Total Hydrocarbon (THC) which exceeds 5ppm will be considered in the abnormal range at our website |
Note: This
ambient air pollution raw data is real time data receiving from our Ambient Air Qulaity Mobile Lab, this data is updating on the bases of average concenterations of 30
minutes for each pollution indicator
