Abstract

The aim was to the assess the health impact of substances measured in the air originating from the decomposition of organic components of sewage sludge in the landfill. Methods: The study was performed at the Severny landfill in a suburb of Saint Petersburg. Sanitary and chemical methods of landfill emissions research we applied. Health risk assessment of the chemicals polluting the air was used. Results. In total, 30 pollutants are emitted from the landfill to the air with the total emission of 768.11 tons/year. The main pollutant was methane. The emissions contained 12 pollutants with a carcinogenic effect. A total of 18 substances comprised 99.9 % of the total index of non-carcinogenic hazard with dihydrosulfide (hydrogen sulfide), formaldehyde and ammonia being the main contributors. Conclusions. The maximum values of carcinogenic risk from exposure to formaldehyde at the calculated points reached 5.8x10-6. The levels of individual carcinogenic risk from formaldehyde exposure correspond to the second risk range (maximum permissible). The value of the total individual carcinogenic risk does not exceed the value of 7.4E-06. The maximum values of the hazard factors for chronic exposure are due to hydrogen sulfide - 0.27. The maximum values of the exposure hazard index at calculated points on the respiratory system are 0.46; on the immune system - 0.16; on the eyes - 0.15. These risk levels were rated as minimal.
