Pollution Episode

The complex terrain basin of Amyntaio – Ptolemais – Kozani in Western Macedonia of Greece is an area characterized by increased industrial activity and therefore it demands continuous and assiduous environmental monitoring. A prolonged particulate matter air pollution episode was recorded in the area during November 2009. Basic meteorological aspects are analyzed, during the episode period. Daily and hourly PM10 and PM2.5 concentration measurements were used along with surface and lower atmosphere hourly meteorological parameters from 13 measuring stations. The observational data were supported by data produced by the meteorological component of an air pollution model. The overall analysis showed that the episode was primarily the result of the synoptic setting of the middle and lower troposphere. An Omega blocking pattern which gradually transformed to a high-over-low pattern prevailed over central and southern Europe during the episode’s period. The examination of the vertical wind field in the lower troposphere and appropriate stability indices, revealed a continuous absence of significant convection. The weak horizontal wind field near the surface and the reduced mixing height combined with the lack of synoptic forcing resulted in the trapping of the pollutants in the lower troposphere and the recording of increased airborne particulate matter concentrations. The radical change of the synoptic setting in the first days of December marked the end of the episode.

Optimum Speed

One of the major pollutants emitted by diesel engine is particulate matter (PM). The main concerns about PM are their adverse effects in the urban area. Therefore researchers are now constantly working on alternative fuels which are clean and efficient in combustion. One of the most promising alternatives fuel is vegetable oils and their derivatives. Based on this study, the characteristics of indirect injection diesel engine in term of the PM have been investigated experimentally. The experiments were conducted experimentally using four cylinder diesel engine. This paper presents an experimental study of PM using mineral diesel and palm-diesel (B100) as a fuel. The result shows highest percentage count for both mineral-diesel and palm-diesel at PM diameter range of 121-160 nm. In addition, the result also indicates that at 2500 rpm the PM for palm-diesel is lower than mineral-diesel for all size range. Thus, at 2500 rpm, it is the optimum speed in order to have a minimum PM for palm-diesel.
