Air Pollution Measurements
Though burning of electronic cables and wires at Agbogbloshie have significantly decreased over the course of the past 2 years, burning of tires, household and municipal waste continue. Therefore, determining the success of the project based solely on air pollution measurements remains difficult. Particulate matter with a diameter of less than 2.5 microns (PM 2.5) is a good indicator of air pollution Image 2: Air pollution from refuse burning at Agbogbloshie that has the potential to harm human health. This metric was therefore chosen as an indicator of project success within the monitoring and evaluation phase. Unfortunately, due to unrelated waste burning as pictured in Image 2 (taken in April 2017), levels of PM 2.5 remain exceedingly high at the site. PM 2.5
samples taken at all locations exceed the standard of 0.035 mg/m3. This is unsurprising, as the former cable ‘burn site’ has now transformed into a refuse burn site. However, the rate at which several of the air pollution measurements have increased is surprising. For instance, at the bridge located adjacent to the burn site, air pollution levels exceeded 0.6 mg/m3 in April 2017, 17 times the maximum acceptable level. This indicates that even though cable burning has decreased at Agbogbloshie, refuse burning is likely increasing.
