| Description for sampling analysis |
: |
Manual sampling.Sample air from intake of 3 meters above ground is introduced into the instalation which consist of a flowmeter, a critical orifice and an absorption tube. Sampling interval is 24 hours starting at 1 PM. Samples are stored for 30-40 days in a fridge before beeing transported to the lab for analise. |
