Furthermore, the marine influence in the region was manifested in several locations by a clear chloride deficit due to the reaction of sea salt with acidic anions like sulfates and nitrates (Kocak et al. 2004a, b Kouyoumdjian and Saliba 2006 Saliba et al. 2007). It has been reported that PMio composition along the Mediterranean coast (i.e. Erdemli, Turkey) contained up to 90% of sea salt and mineral dust, whereas PM2.5 mainly contained anthropogenic pollutants emitted locally and/or transported from neighboring locations (Hassanien and Abdel-Latif 2008 Kocak et al. 2007a, b, 2009).

A field study was conducted in March-April 1992 on El Yunque peak in Puerto Rico, a site that is influenced by both marine air masses and anthropogenic emissions, to determine the relative contributions of sulfate and organic aerosols...
