Oil refining, oil storage, petrochemical and organic chemical activities, chlorine chemistry, steel and metal working, chemical plants, waste incineration plant, port
Hospitalisations for cardiovascular and respiratory diseases
Poisson regression models
Coupling of a dispersion model (ADMS4), a meteorological model and kriging to assess the SO2 levels
GPs activity: data on consultations, chronic conditions, hospital admissions, and current drug treatments. Lung function, Self-reported respiratory, and nonrespiratory health including asthma
Age and sex standardised rates and ratios, questionnaires (6399 adults, 1888 children) time series
Perceived exposure areas (criteria not specified), modeled exposure (model not specified) 24-hour mean daily measures of SO2 and smoke over 56 months (1987–91)
Distance (no wood factories <2 km from home and school (“unexposed” group) at least 1 low emission factory (but no chipboard industries) <2 km from home or school (group “at low exposure”), at least 1 chipboard industry <2 km from home or school (group “at high exposure”)
Health status, pulmonary function tests (PFT), forced vital capacity (FVC) and forced expiratory volume during the first second (FEV1)
Questionnaires (ATS and National Heart and Lung Institute) (1492 children)
* SO2 during acute episodes ( and SO2 measurements above 0.125 and 0.070 ppm, respectively, during 30 mn), based on a map interpolated from 12 monitoring stations
Cities in a 5-kilometer radius, communities established downwind of the petrochemical complex and thus, under greater influence of its dispersion plume (A, B, C), were classified as “exposed communities” (ECs) Those upwind of the plant and thus less exposed to its dispersion plume (D, E) were used as reference communities (RCs)
Respiratory health, lung function (forced expiratory volume)
Questionnaires (1181 children)
* SO2 during acute episodes ( and SO2 measurements above 0.125 and 0.070 ppm, respectively, during 30 mn), based on a map interpolated from 12 monitoring stations
