Abstract

Airborne­ particulate­ matter­ samples­ collected­ in­ sites­ under­ petrochemical­ influence,­ in­ Triunfo­ city­ –­ Rio­ Grande­ do­ Sul,­ Brazil,­ were­ analyzed ­by ­GC/MS-SIM­ for ­nitro-naphthalenes.­ Total­ Suspended­ Particulates ­(TSP)­ samples­ collected ­monthly,­ during­ summer,­ autumn,­ winter­ and­ spring­ of­ 2000­ and­ grouped­ into­ three­ pools,­ January-April;­ May-August;­ September- December,­ and­ three­ samples­ of­ particulate­ matter­ PM10,­ corresponding­ to­ the­ months­ of­ February,­ June­ and­ August­ of­ 2005 ­were­ analyzed. ­The­ organic ­extracts,­ obtained­ by­ sonication­ with­ dichloromethane,­ were­ previously­ investigated­ for­ the­ presence of nitrocompounds with mutagenicity activity, using Salmonella/microsome assay with sensitive strains for these substances.­ The ­mutagenic ­response­ was­ observed­ for­ all samples ­in­ different­ levels, ­demonstrating­ the­ presence ­of­ mono­ and­ dinitro-PAHs­ in­ the­ extracts.­ The­ chromatographic­ analysis­ allowed­ verifying­ the­ predominance­ of­ dinitronaphthalenes­ for­ the ­samples­ corresponding­ to­ the­ winter ­months,­ both ­for­ PTS­ sample,­ May-August,­ and­ PM10­ samples,­ relative­ to ­June­ and­ August.­ These ­results ­allowed­ characterizing, ­in ­agreement­ with ­the ­mutagenic ­assay,­ the ­presence ­of­ nitronaphthalenes­ in­ the­ samples.
