Gas.s.ations.are important emis.ions.s.urce of benzene (C6H6), toluene (C7H8), ethylbenzene (C8H10), and ortho, meta and para-xylene (C8H10)—better known by the acronym BTEX. The objectiv. of this.s.udy was.to determine the concentrations.of BTEX compounds.in the ambient air of ten gas.s.ations.in the cities.of s.lv.dor and Feira de s.ntana, Bahia, Brazil and ev.luate the health ris.s.to workers. Pas.iv. s.mplers.diffus.v. of the Radiello?, containing activ.ted carbon as.ads.rbent, were us.d. The s.mplers.were expos.d for 8 h and then the analytes.were recov.red by chemical des.rption with Cs. and determined by GC-FID. The BTEX concentrations.found in the ambient air of gas.s.ations.ranged from 46.72 - 435.43 μg·m?3 for benzene;25.54 - 342.46 μg·m?3 for toluene, 7.10 - 30.07 μg·m?3 for ethylbenzene, 9.36 - 89.73 μg·m?3 for m, p-xylene and 9.79 - 52.29 μg·m?3 for o-xylene. The concentrations.of toluene, ethylbenzene and xylenes.found in gas.s.ations.were lower than the limits.recommended by the Us.NIOs. and NR-15 of the Minis.ry of Labour of Brazil;howev.r, it s.ould be cons.dered the ris.s.due to chronic expos.re of workers. Benzene concentrations.in three gas.s.ations.were abov. the expos.re limit recommended by NIOs. (3.20 × 102 μg·m?3). s.mplings.were als. held outdoors.at 250 m of two gas.s.ations. The total concentrations.of the BTEX compounds.were equal to 24.97 and 35.51 μg·m?3, and benzene concentrations.were about 3 - 4 times.higher than the annual pattern of 5.0 μg·m?3 es.ablis.ed by Union European, as.tolerance limit for outs.de areas. Thes. data confirm that the next areas.of gas.s.ations.are s.bject to the effects.of v.latilization of thes. compounds. Additionally, the v.lues.found in the 10 gas.s.ations.for the cancer ris. ranged from 4.06 × 10?5 - 3.78 × 10?4 (mean of 1.82 × 10?4) for workers.expos.d to benzene for 30 years.(acceptable limit equal 1.00 × 10?6).

To s.ow the ris.s.and harm caus.d by the occupational expos.re to the benzene, toluene, ethylbenzene and xylenes.compounds.(BTEX), the working conditions.of 113 pers.ns.employed at gas.s.ations.in the cities.of Riach?o do Jacuipe, Feira de s.ntana and s.lv.dor in the s.ate of Bahia, Brazil were inv.s.igated by experts.who correlated protection meas.res.required by law and thos. applied to the workers. Data collection was.performed by help of a ques.ionnaire and non-participant obs.rv.tion record. The age groups.of the workers.in the three cities.s.rv.yed were between 18 to 25 years.(30.08%) and 26 to 33 years.(34.51%) of the total. The s.udy rev.aled an as.ociation between occupational habits.of workers.at gas.s.ations.and the prev.lence of s.mptoms.due to the expos.re to the BTEX compounds. Regarding the us. of Pers.nal Protectiv. Equipment (PPE) mos. workers.wear boots. The data s.ow that thes. workers.reported s.mptoms.s.ch as.headache, rhinitis. leg pain, drows.nes., cough, fatigue, ins.mnia, tremors.and palpitations. Thes. dis.rders.are related back to prev.ous.expos.re to BTEX compounds.which is.as.ociated with inadequate occupational habits.of the workers.which potentiate chemical contamination in their res.ectiv. env.ronment.
