“…The concentrations were comparable with the data recorded in Xi'an, Beijing, Shanghai, Guangzhou and Qingdao (Feng et al, 2006;Wang et al, 2008;Guo et al, 2009;Wei et al, 2015a), but much higher than other areas being governed by better emission control (e.g., Hong Kong) or less influenced by local or regional pollution such as Sanya and Tibetan Plateau (Chen et al, 2014;Wang et al, 2015a). The average level was also higher than that in most developing countries (Tham et al, 2008;Andreou and Rapsomanikis, 2009;Li et al, 2009;Wingfors et al, 2011).…”

“…The occurrence level of SO 2 here was higher than the winter season average in Lahore (7.2 ppb), Pakistan (Biswas et al, 2008), Taichung (0.99 ± 0.34 ppb), Central Taiwan (Cheng and Horng, 2007), urban side of Mt. Gokurakuji (2.48 ppb) and HigashiHiroshima (2-12 ppb) in Japan (Chiwa et al, 2008;Tham et al, 2008), and were also much higher than those measued in surrounding places such as Tanah Rata (0.1 ppb) and Lawa Mandau (0.2 ppb) in Malaysia, and Bukit Kototabang (0.07 ppb) and Kalimantan (0.15 ppb) in Indonesia (Carmichael et al, 2003).

This report describes the results of an inter-comparison study conducted for the sampling and analysis of NO 2 and SO 2 by using different type of passive samplers in tropical urban environment. For this purpose, field experiments were proposed to be conducted by two round robin tests from Sept. 2007 to Aug. 2008 in Singapore. A set of different types of passive samplers have been exposed to ambient air at atmospheric research station in National University of Singapore along with suitable active samplers (as reference method) for a sufficient period of time (3-4 weeks). Annular denuder system (ADS) active sampling data showed that NO 2 concentration level (23.8-28.1 ppb) in Singapore was slightly higher than the WHO guideline but SO 2 concentration (12.5-14.9 ppb) was approximately twice the value of WHO guideline. For the two round robin tests, accuracy analysis by using active sampling data as reference demonstrated that grand mean values from passive air sampling (PAS) and active sampler average concentrations, for both NO 2 and SO 2 , are in close agreement with each other. Precision evaluation based on the triplicate samplers co-located at the same sampling siteSingapore showed that most of the passive samplers applied here had repeatability. ANOVA statistical analysis also showed no significant difference between the measurement data obtained by different type of passive samplers for both round robin tests in Singapore.

“…We were also able to use exposure to atmospheric NO 2 , a marker of air pollution, as a proxy measure of atmospheric PAH. Although direct estimates of airborne PAH were not available, studies have shown moderate to strong correlations between PAH in air and other markers of air pollution such as NO 2 (Tham et al 2008; Wilhelm et al 2011). Moreover, in the absence of a strong correlation between dietary and atmospheric PAHs, which we have no reason to expect in this population, potential confounding by this variable is likely to be modest.…”

“…B(a)P is absorbed onto fine particles and studies have found moderate to high correlations between atmospheric concentrations of fine particles, B(a)P and nitrogen dioxide (NO 2 ) (Hazenkamp-von Arx et al 2004; Tham et al 2008; Wilhelm et al 2011) since most of these pollutants, including B(a)P and NO 2 , come from the traffic (Lodovici et al 2003; Varea et al 2011; Wilhelm et al 2011). As exposure to NO 2 during pregnancy has been related to reproductive outcomes (Ballester et al 2010), in this study we assessed possible confounding using residential outdoor NO 2 as a proxy indicator.…”

Background Previous studies have reported maternal exposure to airborne polycyclic aromatic hydrocarbons (PAH), as well as DNA adducts reflecting total PAH exposure, to be associated with reduced fetal growth. The role of diet, the main source of PAH exposure among non-smokers, remains uncertain. Objective To assess associations between birth weight, length and small size for gestational age (SGA) with maternal intakes of the genotoxic PAH benzo(a)pyrene [B(a)P] during pregnancy, exploring potential effect modification by dietary intakes of vitamin C, vitamin E, alpha- and beta-carotene, as well as glutathione S-transferase P1 (GSTP1) polymorphisms, hypothesized to influence PAH metabolism. Methods 657 women in the INMA (Environment and Childhood) Project from Sabadell (Barcelona) were recruited during the first trimester of pregnancy. Dietary B(a)P and nutrient intakes were estimated from food consumption data. Genotyping was conducted for the Ile105Val variant of GSTP1. Multivariable models were used to assess associations between size at birth and dietary B(a)P, evaluating potential interactions with candidate nutrients and GSTP1 variants. Results There were significant interactions between elevated intakes of vitamin C (above the mean of 189.41mg/day) and dietary B(a)P during the first trimester of pregnancy in models for birth weight and length (P<0.05), but no interactions were found with other nutrients. B(a)P intakes were associated with significant reductions in birth weight and length (coefficient±SE for a 1-SD increase in B(a)P: −101.63±34.62 g and −0.38±0.16 cm, respectively) among women with low, but not high, vitamin C intakes. Elevated dietary B(a)P was also associated with increased risk of SGA births among women with low dietary vitamin C. Among these women, associations were strongest in those carrying the GSTP1 Val allele, associated with lower contaminant detoxification activity. Conclusion Results suggest that dietary B(a)P exposure may impair fetal growth, particularly in genetically susceptible populations, and that increasing maternal intakes of vitamin C may help to reduce any adverse effects.
