PD CEN/TR 16998 is focused on the presence of nitro- and oxy-PAHs in ambient air. It describes how nitro- and oxy-PAH are formed, what typical concentrations are found, what is known about their toxicity, and what sampling and measurement techniques are available.
The conclusions of PD CEN/TR 16998 are that nitro- and oxy-PAHs concentrations are present in the atmosphere in levels that are of concern regarding their high toxicity. Information on the presence of these compounds in ambient air is as relevant as information about PAHs. Validated techniques for the measurement of nitro- and oxy-PAHs are available.
PD CEN/TR 16998 on ambient air is relevant to:
Nitro-PAHs and oxy-PAHs are found in ambient air samples and there are strong indications that they are as harmful as PAHS.
PD CEN/TR 16998 provides a report on the complete understanding of the origin, toxicity, concentrations of nitro- and oxy-PAHs.
PD CEN/TR 16998 describes the performance characteristics and sets the relevant minimum criteria required to determine the concentration of nitro- and oxy-PAHs.
In PD CEN/TR 16998, performance criteria and test procedures for measuring air quality are provided to test and manufacture air quality measuring devices. This helps create an improved solution to deal with harmful gasses emitted by stationary sources, which are very toxic.
As a whole, PD CEN/TR 16998 is a best practice report that provides complete requirements and test procedures for measuring nitro- and oxy-PAHs concentration and controlling their quality, which will reduce pollution, increase efficiency, and ease health concerns.
