| Popis: |
The Salt River project has been continously monitoring visibility in the vicinity of an isolated coal fired power plant located in Northern Arizona. Daily visibility and regular ambient particulate matter measurements are conducted from a monitoring site situated near to the power plant. Visibility is measured by a photographic photometric technique and a subjective technique (human observer) and particles are measured with high-volume and size segregated high-volume samplers. Data obtained from these measurements have been used for determining trends near the monitoring site. It has been found that visibility shows a temporal variation related to meteorological, ambient air quality and visibility reducing pollutants from regional sources. Also, there exists a measurable level of background fine particulate matter which plays a definite role in the visibility impairment in the area surrounding the power plant. |
