“…No ventilation was found at the site of vendor (I-3), which resulted in a high PM 10 (17.2 mg/m 3 ). Previous literature indicates that the emission amounts of PAHs varied significantly with the use of different fuels, varying temperatures, and different foods prepared (Phillips, 1999;Mastral et al, 2000;Venkataraman Kuo et al et al, 2002). All three vendors in group (I) used charcoal as fuel and all their stoves were similar in shape and design.…”

Three types of popular vendors, including meat and non-meat food (e.g, fishballs), vendor group (I), rice sausage sandwiches vendor group (II), and roasted corn on-the-cob vendor group (III), from the night markets of Taiwan were chosen for this research. The average concentrations of carcinogenic polycyclic aromatic hydrocarbons (car-PAHs) were 2445 ng/m 3 for vendor (II), 2276 ng/m 3 for vendor (II), and 133 ng/m 3 for vendor (III). Vendors groups (I) and (II) had exposure levels of Benzo(a)pyrene (BaP)-equivalent doses (BaP eq ) approximately 16 and 13 times higher than those for vendor group (III). The daily exposure doses of BaP eq in working duration for vendor group (II) and (II) were 2.80 and 2.28 mg/day, respectively. The employees of five offices on campus were chosen as a control group. The daily exposure doses of BaP eq during working hours for vendor group (II) and (II) were about 22 times and 18 times, respectively, higher than those for control group. This exposure dose for vendors group (III) (0.18 mg/day) was comparable with the dose for control group (0.13 mg/day). The whole-day exposure doses of t-PAHs, car-PAHs, BaP, and BaP eq for vendor groups (I) and (II) were very close to those during daily working hours. However, the daily exposure doses of BaP eq during working hours for vendor group (III) occurred only in a proportion of 62% of the whole-day exposure doses.

“…The aerosols generated were collected using a virtual impactor-based dichotomous sampler (Model 241, Graseby Andersen Inc., USA) operated at a total flow rate of 16:7 l min À1 : It collected particles in two size fractions, i.e., 0.02-2:5 mm and above 2:5 mm aerodynamic diameter on 37 mm quartz fiber filters (QM-A, Whatman International Ltd., UK), pre-baked at 6001C for 4 h for removing organic contaminants. Particle and PAH size distributions from these stove-fuel systems showed almost no mass above an aerodynamic diameter of 2 mm (Venkataraman and Rao, 2001;Venkataraman et al, 2002). As the emissions containing mass of particles and related mutagenic constituents lay in particles smaller than 2 mm diameter, we expect the mutagenicity to be present in this particle size range, leading to the choice of the PM2.5 fraction for mutagenicity testing.…”

“…Smoke generated by the combustion of wood and other biomass fuels contains many health damaging pollutants including particulate matter, carbon monoxide, aldehydes, nitrogen and sulfur oxides, and polycyclic aromatic hydrocarbons (PAH) (Joshi et al, 1989;Naeher et al, 2007;Venkataraman et al, 2002;Zelikoff et al, 2002;Zhang and Smith, 2007). Household biomass fuel combustion compared to the use of cleaner fuels such as gas could contribute significantly more to indoor levels of these pollutants, including PAHs (Bhargava et al, 2004;Hamada et al, 1991;Oanh and Dungs, 1999;Viau et al, 2000).…”

Women and children in developing countries are often exposed to high levels of air pollution including polycyclic aromatic hydrocarbons (PAHs), which may negatively impact their health, due to household combustion of biomass fuel for cooking and heating. We compared creatinine adjusted hydroxy-PAH (OH-PAH) concentrations in pregnant women in Trujillo, Peru who cook with wood to levels measured in those who cook with kerosene, liquefied petroleum gas or a combination of fuels. Seventy-nine women were recruited for the study between May and July 2004 in the first trimester of their pregnancy. Urine samples were collected from the subjects in the first, second and third trimesters for OH-PAH analyses. The concentrations of the OH-PAHs were compared across the type of fuel used for cooking and pregnancy trimesters. The relationships between OH-PAHs levels in the first trimester and concurrently measured personal exposures to PM 2.5 , carbon monoxide and nitrogen dioxide together with their indoor and outdoor air concentrations were also investigated. Women cooking with wood or kerosene had the highest creatinine adjusted OH-PAH concentrations compared with those using gas, coal briquette or a combination of fuels. Concentrations of creatinine adjusted 2-hydroxy-fluorene, 3-hydroxyfluorene, 1-hydroxy-fluorene, 2-hydroxy-phenanthrene and 4-hydroxy-phenanthrene were significantly higher (p<0.05) in women who used wood or kerosene alone compared with women who used liquefied petroleum gas (LPG), coal briquette or a combination of fuels. An increase in the concentrations of creatinine adjusted 9-hydroxy-fluorene, 1-hydroxy-phenanthrene, 2- Conflict of interest statementThe authors declare no conflict of interest.

Weak positive correlation (Spearman correlation coefficient, ρ<0.4; p<0.05) was observed between all first trimester creatinine adjusted OH-PAHs and indoor (kitchen and living room), and personal 48-h TWA PM 2.5 . Women who cooked exclusively with wood or kerosene had higher creatinine adjusted OH-PAH levels in their urine samples compared to women who cooked with LPG or coal briquette.
