PRELIMINARY ASSESSMENT OF AMBIENT AIR QUALITY - AGGLOMERATIONS AND ZONES IN WEST POMERANIAN

VOIVODESHIP:

• 1 agglomeration - Szczecin (Number of inhabitants: 414 000)

• 20 powiats (including cities: Koszalin and Świnoujście)

• PROTECTION OF HUMANS HEALTH:BENZENE (C6H6)NITROGEN DIOXIDE (NO2)

SULFUR DIOXIDE (SO2)PARTICULATE MATTER PM10LEAD (Pb)CARBON MONOXIDE (CO)OZONE (O3)

• PROTECTION OF ECOSYSTEMS:SULFUR DIOXIDE (SO2)NITROGEN OXIDES (NOX)OZONE (O3)

PRELIMINARY ASSESSMENT OF AMBIENT AIR QUALITY– CRITERIONS AND POLLUTIONS :

SYSTEM OF AIR QUALITY MONITORING, IN LINE WITH THE PRELIMINARY ASSESSMENT OF AIR QUALITY IN WEST POMERANIAN VOIVODESHIP,

BASED ON:

• AUTOMATIC AND MANUAL MEASUREMENTS;• INDICATIVE METHODS (PASSIVE MEASUREMENTS)• MODELLING OF THE DISTRIBUTION OF POLLUTANTS

AIR QUALITY MONITORING NETWORK IN SZCZECIN(without passive measurement stations)

LV = 50 ug/m3

SZCZECIN_RODŁA SQUARE (THE TRAFFIC STATION)42 days with daily mean concentrations above 50 ug/m3

Conclusions: PM10 in Szczecin Agglomeration

In 2004 less than 35 exceedance of PM10 limit values + margins of tolerance → no program necessary

In 2005 margins of tolerance for PM10 no exist

In 2005: at Traffic station 42 days with daily mean concentrations above 50 ug/m3

→ programs and action plans could be necessary for the near traffic sites

NO2 IN SZCZECIN AGGLOMERATION:

Conclusions: NO2 in Szczecin Agglomeration

exceedance of the NO2-limit value is possible (see Szczecin Hot Spots) → programs and action plans could be necessary in future

further investigations at near traffic sites

no exceedance of NO2 limit values + margins of tolerance since 2002 → actually no program necessary
