Many Sources

The problem of determining the percentage contribution of a single power plant to ambient levels of total suspended particulates, when there are many sources of identical particulates in a community, has been approached by injecting a gas tracer (SF6) into the stack effluent of the power plant. On the premise that small particles leaving the stack after an electrostatic precipitator are dispersed in the same manner as a gas, a simple dilution ratio between gas emitted to gas captured is applied to particulates emitted to obtain the contribution to total particulates captured by high-volume air samplers. Tracer tests at the Kanawha River plant of the Appalachian Power Company indicated the plant’s contribution to total suspended particulates was below 10 percent of the total concentration observed in the community. This value was further substantiated when similar results were obtained by multiple regression analyses between stack emissions, wind speed, wind direction, and observed total suspended particulates.

Future Consequences

Although the current situation poses challenges to foretelling the future consequences of coronavirus spread, we consider that environmental load-related research has become more important than ever before. Many experts believe that in the framework of increasingly dire public health emergency, policy and decision makers should facilitate COVID-19 outbreak to transitioning to sustainable consumption and production. With the purpose of evaluating the importance of sustainability efforts, here we describe the total suspended particulates (TSP), originating from traffic emissions, caused by air pollution in the three most populous cities of Ecuador. Compared are measurements taken prior to, during, and after (i) traffic measures entered into force at national level; (ii) curfew entered into force at national level; and (iii) quarantine entered into force (in Guayaquil, and whole Guayas province). We documented significant decrease in TSP emissions (PM2.5 and PM10) as compared to normal traffic proceeding in four-lane roads, in the cities of Quito, Guayaquil, and Cuenca. The most substantial drop in suspended particulate values (96.47% decrease in PM2.5) relative to emissions observed prior to restricting traffic occurred in Cuenca.

<p>This study examined the toxicity potential of total suspended particulate in the airshed of a haulage vehicle park located in a major highway connecting Lagos, the commercial centre of Nigeria to its other parts. It has an approximate area of 0.6 km2. Ambient air total suspended particulates (TSP) were monitored at five different sub- parks using the GT331 particulate monitor. A control sampling point was also set at about a kilometer southward of the sub-parks. The average measured particulate concentrations within the park ranged between 197.07 and 653.28 &micro;g m-3 with an average of 334.5 &micro;g m-3 but at the control point, it was between 18.5 and 46.6 &micro;g m-3 with an average of 36.23 &micro;g m-3. An assessment of toxicity potential of these particulates shows unhealthy air conditions at the haulage park. It was between 0.58 and 6.00 at the park&rsquo;s sampling points but ranged between 0.11 and 0.33 at the control location. This study establishes that haulage vehicles may contribute significantly to its host airshed degraded air quality thus calls for appropriate regulatory measure to protect commuters plying the major highway around the park.</p>

Who Guideline

The levels of total suspended particulates (TSP) within the complex of a steel factory (Fletcher Pacific Steel Fiji) have been investigated through high volume air sampling. The levels of TSP inside and outside (in the ambient environment) the factory has been found to be in the range of 121-339 and 33-80 μg m-3 respectively. The levels inside the factory exceed the WHO guideline by a factor of 2-4. The management of the factory was very proactive to determine the air quality for records and to safeguard the health and safety of all the employees, contractors, and visitors. At the request of the factory, the exposed filters were analysed by neutron activation and gamma-ray spectroscopy techniques and the results are presented.

The objective of this study was to investigate an association between pre-harvest sugarcane burning and respiratory diseases in children under five years of age. The following data were collected in five schools in the city of Araraquara, SP, Southeastern Brazil, between March and June 2009: daily records of absences and the reasons stated for these absences, total concentration of suspended particulate matter (µg/m3), and air humidity. The relationship between the percentage of school absences due to respiratory problems and the concentration of particulate matter in March and from April to June presented a distinct behavior: absences increased alongside the increase in particulate matter concentration. The use of school absences as indicators of this relationship is an innovative approach.
