Air Pollution: Health Risk Assessment

First, we briefly described the potential health effects of these pollutants with reference to the most up to date state of knowledge on the science of the health effects of key pollutants (PM10, PM2.5 and NO2) in New Zealand (Hales et al., 2021) and globally (WHO, 2022). [...] Based on the frequency of complaints it is apparent that offensive and objectionable odours are reducing the quality of life and adversely impacting on the wellbeing of residents in and around the Mount Maunganui Airshed. [...] ‘Breathing’ losses refer to vapours in the headspace of Air Pollution Health Risk Assessment: Mount Maunganui 13 the storage tank discharging to atmosphere due to changes in the tank temperature and pressure throughout the day and throughout the year. [...] 3.2 QUANTIFIED RISK ASSESSMENT: PM10, PM2.5 AND NO2 Air pollution health risk assessments typically compare the estimated health effects in a population exposed to a source of concern, with the estimated health effects in the same population without the source of concern. [...] The PAF is calculated using the exposure–response function (the relative increase in the health effect for every increment of air pollution (for example, 1.105 for every 10 µg/m3 of annual average PM 1110) and the exposure (the average pollution concentration in the area of interest - for example, an annual average PM10 concentration of 20 µg/m3).
