Passive sampling of SO2 and NO2 ambient air concentrations in Cairo. NILU OR
A screening study was undertaken in greater Cairo to check and verify the ambient air pollution monitoring network operated by EIMP/EEAA. The passive samplers were installed in field to measure ground level concentrations in different microenvironments as a result of emissions from traffic and industry. The possibilities for exceeding the EEAA Law no. 4 and the World Health Organisation¿s (WHO) air quality guidelines for SO2 were identified in two areas of Cairo. NO2 concentration limits were high in some selected streets. The passive sampling results compared reasonably well with the permanent network operated by EIMP/EEAA.

Partikkelforurensning fra piggdekk. NILU OR
Det er gjennomført en sammenstilling av målinger av PM2,5 og PM10 i større norske byer i 1990-årene. Rapporten gir en oversikt over overskridelser av kartleggings- og tiltaksgrenser i Forurensningsloven og av SFTs anbefalte luftkvalitetskriterier. Det er også beregnet bidrag til PM2,5- og PM10-konsentrasjonene både for årsmiddelverdier og de høyeste døgnmiddelverdiene fra veidekkeslitasje/oppvirvling fra veibanen, bileksos og andre lokale kilder og langtransporterte luftforurensninger.

Particulate Matter Research and Management in Serbia
Clean air is a basic requirement for human health and well-being. According to [1], air pollution is the largest environmental health risk in Europe, with PM being responsible for majority of the adverse effects. The most commonly used metrics for PM is mass for different PM sizes by aerodynamic diameter: inhalable PM includes PM10 for particles equal or smaller than 10 μm, PM2.5 for those equal or smaller than 2.5 μm, and ultrafine particles for those smaller than 100 nm. The smaller the particles are, the deeper they penetrate deep into the lungs and even enter the cardiovascular system, increasing the risks to human health [2]. New ways of characterizing PM, and new understanding of mechanisms of adverse health effects, are emerging.
