The system of automatic state ambient air monitoring stations in Lithuania consists of 14 urban air quality monitoring stations operating in Vilnius, Kaunas, Klaipėda, Šiauliai, Panevėžys, Jonava, Kėdainiai, Naujoji Akmenė and Mažeikiai and 3 integrated monitoring stations operating in Aukštaitija, Žemaitija and Dzūkija National Parks. Concentrations of the following pollutants are measured at automatic air quality monitoring stations: particulate matter PM10, fine particulate matter PM2.5, nitrogen oxides (NO2, NOx, NO), sulfur dioxide (SO2), carbon monoxide (CO), ozone (O3), benzene, mercury. The tests and measurements shall be carried out in accordance with the requirements of Directives 2004/107/EC of the European Parliament and of the Council relating to arsenic, cadmium, mercury, nickel and polycyclic aromatic hydrocarbons in ambient air and 2008/50/EC on ambient air quality and cleaner air for Europe.

Lithuanian state air monitoring measurement data (semi-automatic sampling) Measurements was carried out at 5 state-monitored air quality research stations: Vilnius, Žirmūnai (0003), Kaunas Petrašiūnai (0041), Klaipėda Centras (0031), Šiauliai (0022), Aukštaitija (0051). From the PM10 filters exposed for 1 week (air volume pumping 2.3 m3/h), in the laboratory analyzed and reported monthly average and average annual concentrations in the ambient air of the following heavy metals: Pb, As, Ni, Cd (units of measurement for lead is µg/m3 and for As, Ni, Cd accordingly ng/m3) and the following polycyclic aromatic hydrocarbons (PAHs): benzo(a)pyrene, benzo(b)fluoranthene, benzo(k)fluoranthene, dibenzo(a,h)anthracene, indene(1,2,3-cd)pyrene (units ng/m3). The results of the measurements are presented in accordance with the following legislation: 2008 May 21 Directive 2008/50/EC of the European Parliament and of the Council on ambient air quality and cleaner air for Europe (lead in ambient air measurements); 2004 December 15 Directive 2004/107/EC of the European Parliament and of the Council relating to arsenic, cadmium, mercury, nickel, and polycyclic aromatic hydrocarbons in ambient air.
