“…This happens when the presence of adequate organic precursors and chlorine sources causes the formation of dioxins in post-combustion zones or when the elevated temperatures observed in some cases at fabric filter inlets result in volatilization of dioxins adsorbed onto particles. 13 The fabric filter system is also not efficient in controlling gaseous pollutants such as mercurial vapors, sulfur oxides, and nitrogen oxides, unless they have absorbent or adsorbent additives.…”

“…The components of general hospital waste are similar to those of municipal waste (food waste, administrative waste, yard trash). 13 Most Portuguese hospitals incinerate red bag waste, pathological waste, and a proportion of the general waste. The quantity of general waste incinerated depends upon the hospital concerned.…”

The purpose of this paper is to quantify the production of medical waste from a general hospital and to evaluate the atmospheric pollutant concentrations in gaseous emissions associated with its incineration. A 3.8 kg (bed.day) -1 production of medical waste was estimated for 1998; its incineration is related with an ash production of 0.3-0.4 kg (bed.day) -1 . The concentrations of atmospheric pollutants were estimated using emission factors, comparing the effluents with and without control of atmospheric pollutants. The calculated concentrations were compared with the emission limits established by Portuguese legislation. The results indicate that, if there is no control of atmospheric pollutants, their concentrations exceed the established limits. This is observed even if correct operation and maintenance procedures are used. The emission concentrations of dioxins are higher than the Portuguese emis-

“…Major anthropogenic sources of atmospheric SO 2 include power plants that burn high-sulfur coal, paper and pulp industries, petroleum refineries, industrial processes for roasting of nonmetallic ores, and incineration of solid waste-particularly of hazardous and medical wastes. 4,5 At present, many techniques, such as differential optical absorption spectroscopy ͑DOAS͒, 6,7 correlation spectroscopy ͑COSPEC͒, 8,9 differential absorption lidar ͑DIAL͒, [10][11][12] and tunable diode laser absorption spectroscopy ͑TDLAS͒ techniques 13 are used for monitoring SO 2 in air.…”

Concentration evaluation method using broadband absorption spectroscopy for sulfur dioxide monitoring

We report on an approach for sulfur dioxide monitoring using broadband absorption spectroscopy in the ultraviolet spectral range. The method was applied in real-time measurements and has the advantage of straightforward data evaluation, limited susceptibility for interference from other gases, and low degree of complexity compared with other real-time optical detection techniques having the same precision. Concentration measurement is demonstrated at atmospheric pressure, which is of interest for pollution emission monitoring, yielding a detection limit of about 1ppm with 3s integration time. Comparison is made with low pressure measurements for validation of the accuracy of the method.

Estimating the Wind Direction of Maximum Air Pollutant Concentration

1996

View full text Add to dashboard Cite

SUMMARYThe evaluation of evidence concerning the existence and nature of associations between concentrations of air pollutants and wind direction can aid in investigating relationships between an emission source and measured pollutant levels at nearby sites. In this paper we present a model based on the beta function which can be used to provide an estimate of the direction of maximum pollutant concentration with a corresponding confidence interval. The model was fitted to meteorological and pollutant concentration data collected during two time periods at a site near Charlotte, North Carolina, USA. Estimates and confidence intervals are reported, accompanied with results of hypothesis tests concerning the existence of associations between wind direction and pollutant concentration. Some implications of the results for future monitoring efforts are discussed.
