(State Sanitary Rules-201-97 Protection of atmospheric air from pollution)
| Level of pollution | Degree of air cleanliness | Exceeding of maximum permissible concentration (MPC), degree of points |
| admissible | clean | < 1 |
| inadmissible | weakly polluted | > 1-2 |
| inadmissible | moderate polluted | > 2-4 |
| inadmissible | polluted | > 4-8 |
| inadmissible | heavily polluted | > 8 |

Appendix 1
Scenario – based task: "Technologies and constructions for clearing of industrial aerosol and gaseous emissions in atmosphere"
Arithmetic values of daily average concentration of chemical substances in the atmospheric air of Lenin`sky region of Dnipropetrovs’k for 12 months on the stationary post was established:
| Substances | Maximum concentration limit | Concentration in atmospheric air, mg/dm3 |
| Dust inorganic (with maintenance SiО2 <20 %) | 0.25 | 0.52 |
| Anhydride sulphurous | 0.05 | 0.09 |
| Carbon оxide | 4.7 | |
| Nitrogen dioxide | 0.04 | 0.8 |
| Formaldehyde | 0.003 | 0.005 |
| Maximum allowable pollution index | 12,4 | |
| Index of factual pollution | 34,2 |
1. Give hygienic estimation of quality of atmospheric air by results of laboratory researches, according to the State Sanitary Rules-201-97 "Protection atmospheric air from pollution".
2. Carried out necessary hygienic actions for improvement of condition of atmospheric air in the occupied places.
3. Carried out necessary architecturally – planning measures in order to improve atmospheric air quality in the settlements.
Standard answer:
Index of factual pollution of atmospheric air of Lenin`sky region exceed maximum allowable pollution index in 2.76 (34,2/12,4=2,76). It means that the level of pollution is inadmissible, the degree of air cleanliness is average polluted.
Carried out sanitary inspection of industrial enterprises on the purpose of protection atmospheric air; carry out laboratory research of air samples at the industrial enterprises on the purpose of observance maximum-permissible emissions to atmosphere; make recommendations on the observance of technological actions for air pollution prevention.
