1. Practical skills on the topic: Research and evaluation of particulate air pollution

2. purpose:
Study of particulate air pollution is most often carried out at a workplace assessment, as well as in the evaluation of atmospheric air of populated areas

3. Necessary equipment and devices:
floor scales
Filter AFA or FPP
allonge
aspirator

4. 1 Weigh-clean filter, write it on a paper weight of the filter holder (P1)

5. 2 Collect system for air sampling

6. 3-stretch through the filter of the air at a rate of 15-20 l / min
3-stretch through the filter of the air at a rate of l / min. Within 3-5min

7. 4 to determine the volume of air stretched (B)

8. 5-weighed filter dust (P2)

9. 6 to calculate the dust: x = (p2-p1): Vh1000mg in 1 cubic meter of air

10. 7-assess the level of dust by comparing the "x" to the MPC for this type of dust and for specific conditions (production, air)
