What is PD CEN/TS 16645 – Ambient air about ?
PD CEN/TS 16645 specifies performance characteristics and performance criteria for this measurement method.
PD CEN/TS 16645 specifies a measurement method for the determination of the particle boundpolycyclic aromatic hydrocarbon (PAH) compounds benz[a]anthracene (BaA), benzo[b]fluoranthene (BbF), benzo[j]fluoranthene (BjF), benzo[k]fluoranthene (BkF), dibenz[a,h]anthracene (DBahA), indeno[1,2,3- cd]pyrene (INP) and benzo[ghi]perylene (BghiP) in ambient air.
PD CEN/TS 16645 describes a measurement method which comprises sampling of the selected PAH compounds as part of the PM10 particles, sample extraction and analysis by high performance liquid chromatography (HPLC) with fluorescence detector (FLD) or by gas chromatography with mass spectrometric detection (GC-MS).
PD CEN/TS 16645 is applicable for the measurement of the PAH compounds in the concentration range from approx. 0,04 ng/m3 to approximately 20 ng/m3 for BaA, BbF, BjF, BkF, BaP, INP and BghiP and 0,02 ng/m3 to approximately 2 ng/m3 for DBahA.
Who is PD CEN/TS 16645 – Ambient air for ?
PD CEN/TS 16645 on ambient air is relevant to:
- Manufacturers of air quality controlling devices such as diffusers
- Researchers and scientists
- Chemical Engineer
- Environmentalists
Why should you use PD CEN/TS 16645 – Ambient air ?
PD CEN/TS 16645 specifies requirements and test methods for the determination of performance characteristics of diffusive samplers used for measuring benz[a]anthracene, benzo[b]fluoranthene, benzo[j]fluoranthene, benzo[k]fluoranthene, dibenz[a,h]anthracene, indeno[1,2,3-cd]pyrene and benzo[ghi]perylene in ambient atmospheres.
The methodology described in PD CEN/TS 16645 can be applied to obtain air quality information with a relatively high spatial density that can be used to complement the appropriate siting of fixed monitoring stations, or in the validation of dispersion models.
PD CEN/TS 16645 describes the performance characteristics and sets the relevant minimum criteria required for determining the concentration of benz[a]anthracene, benzo[b]fluoranthene, benzo[j]fluoranthene, benzo[k]fluoranthene, dibenz[a,h]anthracene, indeno[1,2,3-cd]pyrene and benzo[ghi]perylene in air.
In PD CEN/TS 16645, performance criteria and test procedures for measuring air quality are provided to test and manufacture air quality measuring diffusers. This helps create an improved solution to deal with harmful gasses emitted by stationary sources, which are very toxic.
As a whole, PD CEN/TS 16645 is a best practice guidance standard that provides complete requirements and test procedures for determining the concentration of different components in air using a diffuser and controlling their quality, which will reduce pollution, increase efficiency, and ease health concerns.
