“…In contrast, numerous studies have investigated the association between cardiovascular health impact and exposure to particulate matter pollutants from urban sources (eg, vehicular emissions) . Studies have reported a 2% to 20% increase in risk of acute IHD‐related morbidity for a 10 μg/m 3 increase in PM 2.5 levels …”

“…20 Studies have reported a 2% to 20% increase in risk of acute IHD-related morbidity for a 10 lg/m 3 increase in PM 2.5 levels. 3,4,7,11,31,73 Some challenges are involved in investigating the health impacts of wildfire smoke exposure. Wildfires are episodic and short-lived events; therefore, the brief periods of PM 2.5 exposure may not be enough to detect all but the most sensitive health outcomes.…”

BackgroundEpidemiological studies investigating the role of fine particulate matter (PM2.5; aerodynamic diameter <2.5 μm) in triggering acute coronary events, including out-of-hospital cardiac arrests and ischemic heart disease (IHD), during wildfires have been inconclusive.Methods and ResultsWe examined the associations of out-of-hospital cardiac arrests, IHD, acute myocardial infarction, and angina (hospital admissions and emergency department attendance) with PM2.5 concentrations during the 2006–2007 wildfires in Victoria, Australia, using a time-stratified case-crossover study design. Health data were obtained from comprehensive health-based administrative registries for the study period (December 2006 to January 2007). Modeled and validated air exposure data from wildfire smoke emissions (daily average PM2.5, temperature, relative humidity) were also estimated for this period. There were 457 out-of-hospital cardiac arrests, 2106 emergency department visits, and 3274 hospital admissions for IHD. After adjusting for temperature and relative humidity, an increase in interquartile range of 9.04 μg/m3 in PM2.5 over 2 days moving average (lag 0-1) was associated with a 6.98% (95% CI 1.03% to 13.29%) increase in risk of out-of-hospital cardiac arrests, with strong association shown by men (9.05%,95%CI 1.63% to 17.02%) and by older adults (aged ≥65 years) (7.25%, 95% CI 0.24% to 14.75%). Increase in risk was (2.07%, 95% CI 0.09% to 4.09%) for IHD-related emergency department attendance and (1.86%, 95% CI: 0.35% to 3.4%) for IHD-related hospital admissions at lag 2 days, with strong associations shown by women (3.21%, 95% CI 0.81% to 5.67%) and by older adults (2.41%, 95% CI 0.82% to 5.67%).ConclusionPM2.5 exposure was associated with increased risk of out-of-hospital cardiac arrests and IHD during the 2006–2007 wildfires in Victoria. This evidence indicates that PM2.5 may act as a triggering factor for acute coronary events during wildfire episodes.

“…Research has shown that air pollution exacerbates and increases the probability of infections such as acute lower respiratory infections (ALRI) which include acute bronchitis and bronchiolitis, influenza and pneumonia. In addition, air pollution is associated with stroke, chronic obstructive pulmonary disease (COPD) including chronic bronchitis and emphysema as well as ischemic heart disease (IHD) and cancers of the trachea, bronchus and lung (Chiu, 2013;World Health Organization, 2016).…”

Air pollution is a public health emergency (WHO, 2016a). It is the biggest environmental risk to health with a global responsibility for about 1 in 9 deaths annually. In 2013, Statistics SA indicated that 10 % of all deaths in South Africa were attributed to respiratory diseases. Areas with increased industrial growth such as Richards Bay are particularly vulnerable. The paper analyses the spatial and temporal concentration trends of PM₁₀ and SO₂ in Richards Bay over the last two decades; specifically, since the promulgation of national ambient air quality standards (NAAQS) and minimum emissions standards (MES). Mann-Kendell trend tests was applied to monitoring data from the Richards Bay Clean Air Association (RBCAA) to test for an improving or worsening trend and the significance thereof. The pollution concentration data was also compared to NAAQS and the WHO annual guidelines. Overall, results indicate that although there has been a downward trend in the concentration of PM₁₀ and SO₂ emissions in the study area, the trends are not statistically significant. However, there was indication of statistically significant reducing trends in ambient concentrations at some stations. The concentrations at all stations were below NAAQS.

“…The level of atmospheric PM 2.5 is associated with cardiovascular disease and mortality (Pope et al, 2004;Chiu et al, 2013). It is essential to reduce PM 2.5 emission and control its formation in order to lower the level of atmospheric PM 2.5 .…”

PM 2.5 emissions from stationary sources contain a filterable and condensable portion. In this study, USEPA Method 201A/202 are used to measure filterable and condensable PM 2.5 emissions from 5 stationary sources (power plants, boilers, brick manufacturing plant, incinerators and arc furnaces). The average filterable PM 2.5 concentrations for power plant, boiler, brick manufacturing plant, incinerator and arc furnace are 0.75, 16.9, 8.67, 0.15 and 2.12 mg/Nm 3 , respectively. The amount of PM 2.5 residue on the exit tube of cyclone and front half of the filter holder is significantly higher when the filterable PM 2.5 concentrations are low. It is necessary to collect both filter and the residue particulates to avoid underestimation of PM 2.5 emissions. The condensable PM accounts for 61.2%, 73.5%, 44.2%, 52.8% and 51.2% of total PM 2.5 for power plant, boiler, brick manufacturing plant, incinerator and arc furnace plant, respectively. The real PM 2.5 contribution to the atmosphere would be underestimated if condensable PM is not included. The condensable PM fraction increases as the exhaust temperature rises. The inorganic fraction accounts for 89.0%, 69.4%, 72.3%, 89.8% and 72.8% of condensable PM, respectively, for power plant, boiler, brick manufacturing plant, incinerator and arc furnace. The inorganic fraction is dominant in the condensable PM, which might be due to the high content of SO 4 .
