This may explain the direct relationship between waste weight and nitrogen dioxide.
In 1983, the environmental standards were set for other major pollutants: carbon monoxide, nitrogen dioxide, fine particulates, and ozone.
In addition, emissions of nitrogen dioxide, sulphur dioxide and suspended particulate matter from the transport sector and energy use by the transport sector, are considered separately.
Further correlation was observed between: r nitrogen dioxide and oxygen; r nitrogen dioxide and toluene; r nitrogen dioxide and hydrogen chloride; and r toluene and carbon monoxide.
The report also concluded that nitrogen dioxide levels are unlikely to be an important influence on daily variations in asthma occurrence.
I was puzzled by the agreement on nitrogen dioxide.
It identified its emissions of sulphur and nitrogen dioxide as a major factor.
Objectives have been set for a number of air pollutants including nitrogen dioxide.
