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.
A survey of nitrogen dioxide concentrations was undertaken last year as part of our national study to compare results of an earlier survey in 1986.
I agree that we are primarily dealing with nitrogen dioxide.
The carbon reacts with the nitrogen dioxide to form carbon dioxide and nitrogen—both of which are then emitted as gases.
They have tried to repeal or amend the directive which sets legal limits on nitrogen dioxide in the air.
The strategy includes health-based standards for benzene, 1,3-butadiene, carbon monoxide lead particles, sulphur dioxide, nitrogen dioxide and low-level ozone.
The strategy includes health-based standards for benzene, 1,3-butadiene, carbon monoxide, lead, particles, sulphur dioxide, nitrogen dioxide and low level ozone.
The standards for nitrogen dioxide and lead were not breached in 1992.
