The problem of smoke haze pollution in Northern Thailand affects both the environment and residents. main sources are wildfires open burning during dry season, which release many pollutants, especially surface O 3 , impacting health causing an air crisis. aim this research was to study impact biomass on CO, NO 2 levels using Weather Research Forecasting Model with Chemistry (WRF-Chem). simulati...

BACKGROUND Industrialization and urbanization had a devastating impact on public health and caused an increase in health related morbidity and mortality. In fact, asthma is a chronic condition which is considered as one of the significant challenges of public health. In this study, we investigated the association of air pollution and weather conditions with excess emergency ward admissions of a...

BACKGROUND Sudden infant death syndrome (SIDS) affects approximately 1 in 1000 live births and is the most common cause of infant death after the perinatal period. OBJECTIVE To determine the influence of air pollution on the incidence of SIDS. METHODS Time-series analyses were performed to compare the daily mortality rates for SIDS and the daily air pollution concentrations in each of 12 Ca...

The results of a study of the photocatalytic oxidation of uichloroethylene (TCE) in air using titanium dioxide as the catalyst are reported. Dichloroacetyl chloride is found to be an intermediate in the oxidation sequence and carbon monoxide, phosgene, carbon dioxide, hydrogen chloride, and chlorine are found in the product mixture. The yields of each, except chlorine, have been determined usin...
