TY - JOUR AB - BACKGROUND: Transport-related air and noise pollution, exposures linked to adverse health outcomes, varies within cities potentially resulting in exposure inequalities. Relatively little is known regarding inequalities in personal exposure to air pollution or transport-related noise. OBJECTIVES: Our objectives were to quantify socioeconomic and ethnic inequalities in London in 1) air pollution exposure at residence compared to personal exposure; and 2) transport-related noise at residence from different sources. METHODS: We used individual-level data from the London Travel Demand Survey (n=45,079) between 2006 and 2010. We modeled residential (CMAQ-urban) and personal (London Hybrid Exposure Model) particulate matter <2.5μm and nitrogen dioxide (NO2), road-traffic noise at residence (TRANEX) and identified those within 50dB noise contours of railways and Heathrow airport. We analyzed relationships between household income, area-level income deprivation and ethnicity with air and noise pollution using quantile and logistic regression. RESULTS: We observed inverse patterns in inequalities in air pollution when estimated at residence versus personal exposure with respect to household income (categorical, 8 groups). Compared to the lowest income group (<£10,000), the highest group (>£75,000) had lower residential NO2 (-1.3 (95% CI -2.1, -0.6) μg/m3 in the 95th exposure quantile) but higher personal NO2 exposure (1.9 (95% CI 1.6, 2.3) μg/m3 in the 95th quantile), which was driven largely by transport mode and duration. Inequalities in residential exposure to NO2 with respect to area-level deprivation were larger at lower exposure quantiles (e.g. estimate for NO2 5.1 (95% CI 4.6, 5.5) at quantile 0.15 versus 1.9 (95% CI 1.1, 2.6) at quantile 0.95), reflecting low-deprivation, high residential NO2 areas in the city centre. Air pollution exposure at residence consistently overestimated personal exposure; this overestimation varied with age AU - Tonne,C AU - MilĂ ,C AU - Fecht,D AU - Alvarez,M AU - Gulliver,J AU - Smith,J AU - Beevers,S AU - Ross,Anderson H AU - Kelly,F DO - 10.1016/j.envint.2018.03.023 EP - 179 PY - 2018/// SN - 0160-4120 SP - 170 TI - Socioeconomic and ethnic inequalities in exposure to air and noise pollution in London T2 - Environment International UR - http://dx.doi.org/10.1016/j.envint.2018.03.023 UR - https://www.ncbi.nlm.nih.gov/pubmed/29574337 UR - https://www.sciencedirect.com/science/article/pii/S0160412017321256?via%3Dihub UR - http://hdl.handle.net/10044/1/58419 VL - 115 ER -
