It seems like a recurring conversation.
Fire at the Riverton dump.
Here are six quick findings from the report,
1. There was a negative impact on the ambient air quality in Kingston and St. Andrew, as well as parts of St. Catherine, including Portmore and Spanish Town.
2. Forty six (46) pollutants were detected from the analyses conducted on VOC samples; thirty four (34) were detected above the lower concentration limit (0.2μg/m3).
The results of the analysis indicate higher than normal concentrations of benzene and toluene. The recorded benzene concentration was 41μg/m3 at the Spanish Town Road location. This is approximately 2.5 times the highest benzene concentration detected during the 2015 fire at the RSWDS (15.3μg/m3). The highest recorded concentration for toluene of 30μg/m3 was just over 2.5 times the 11.2μg/m3 concentration recorded during the 2015 fire at the RSWDS.
3. The WHO 24-hour limit (25μg/m3) for PM2.5 was exceeded. The highest average daily concentration of PM2.5 (40.58 μg/m3) recorded at the Spanish Town, St. Catherine monitoring station during the period under review was on day three of the fire. The WHO 24-hour guideline limit for PM2.5 was also exceeded at the Duhaney Park monitoring location. The highest recorded concentration was 43.28μg/m3 on August 3, 2018.
4. Seven (7) exceedances of the 1-hour NO2 guideline limit were observed over the period on August 4 and 5, 2018. The highest recorded NO2 concentration was 730.2μg/m3 on August 4, 2018.
5. Results indicate possible health impact especially to sensitive groups.
6. Results of the monitoring also indicated impact on air quality as a result of the Saharan Dust thereby increasing the recorded particulate matter concentrations.
