DOE said its monitoring of the haze situation in the country found the concentration of carbon monoxide was low and did not cause the phenomena.
"The reading on the carbon monoxide concentration is less that the Recommended Malaysia Air Quality Guidelines, that is below 30 ppm (1 hour) or 35 microgrammes per cubic metre (1 hour).
"It does not cause the yellow haze phenomena," DOE said in a statement in clarifying the false information being spread on social media.
DOE drew attention to the fact that the Air Pollutants Index in Malaysia was the best yardstick for measuring the main pollutants in the atmosphere which are fine dust with size less than 10 micrometres (PM10); carbon monoxide; sulphur dioxide; nitrogen dioxie and ozone, in accordance to international standards. - Bernama.
