Occupational exposure to Aldehydes and Ketones
Analysis of occupational exposure to Aldehyde and Ketones Measurement of air quality in the workplace Test with analysis in a certified laboratory
Formaldehyde, aldehydes and ketones are volatile at room temperature. They are captured by a passive sensor including a reagent-impregnated carrier (DNPH).
In the laboratory, the carrier is extracted with an organic solvent and the extract is analysed by liquid chromatography-mass spectrometry.
The test kit includes
The analysis kit is very simple to use and does not require any technical expertise.
The passive sensor should be exposed to the workplace air for a period of 8 consecutive hours.
It can be used in two ways:
Once the sample has been taken, the passive sensor and the sampling form are returned to the laboratory with the prepaid return envelope.
The kit for the analysis of aldehydes and ketones in workplace air has no legal value.
The results are indicative and can be used to prevent occupational exposure to volatile chemicals.
This test kit measures the concentration of aldehydes (including formaldehyde) and ketones in workplace air. It allows the result to be compared with the occupational exposure limit value (OEL) for aldehydes and ketones.
Formaldehyde is a known human carcinogen and a widely used chemical in the workplace. Other aldehydes and ketones can also have an impact on the health of employees.
Air inhaled during work activities may include toxic, carcinogenic, mutagenic and/or reprotoxic (CMR) substances and present health risks to employees.
The monitoring of CMR exposure is a regulatory obligation for employers and must be carried out every year.
Depending on the selected variant, a defined number of aldehydes and ketones are analysed. They are selected from the list of substances analysed in the laboratory. The occupational exposure limit values (OELs) vary from country to country and are presented for France.
