Background: Recent studies have indicated long-term effects on mortality of particulate and sulphur dioxide (SO2) pollution, but uncertainties remain over the size of any effects, potential latency and generalisability. Methods: A small area study was performed across electoral wards in Great Britain of mean annual black smoke (BS) and SO2 concentrations (from 1966) and subsequent all-cause and...

In the early days of abundant resources and minimal development pressures, little attention was paid to growing environmental concerns in Malaysia. The haze episodes in Southeast Asia in 1983, 1984, 1991, 1994, and 1997 imposed threats to the environmental management of Malaysia and increased awareness of the environment. As a consequence, the government established Malaysian Air Quality Guidel...

During the eighties the city of Rijeka was one of the most polluted cities in Croatia with sulphur dioxide due to high emission of this pollutant from industrial plants. In mid-eighties, annual means of SO2 exceeded 100 micrograms/m3 in the city centre, in the Bakar Bay area varied between 70-80 micrograms/m3, while in the suburban residential area they were up to 40 micrograms/m3. In 1995 annu...

OBJECTIVE To investigate the association between ambient concentrations of air pollutants and respiratory and cardiovascular mortalities in Hong Kong. METHODS Retrospective ecological study. A Poisson regression of concentrations of daily air pollutants on daily mortalities for respiratory and cardiovascular diseases in Hong Kong from 1995 to the end of 1998 was performed using the air pollut...

BACKGROUND Recent studies have suggested that air pollutants resulting from vehicle exhaust emissions and burning of fossil fuels, either in combination or individually, may enhance the airway response of asthmatic subjects to inhaled allergen. It was hypothesised that the airway response to inhaled allergen after exposure to a combination of 400 ppb nitrogen dioxide (NO2) and 200 ppb sulphur d...

Cloud-to-ground (CG) lightning flash data collected by the lightning detection network installed at the Korean Meteorological Administration (KMA) have been used to study the urban effect on lightning activity over and around Seoul, the largest metropolitan city of South Korea, for the period of 1989–1999. Negative and positive flash density and the percentage of positive flashes have been calc...

An amperometric biosensor for the detection of polyphenols in wine has been developed immobilizing the two enzymes Tyrosinase and Laccase on graphite screen printed electrodes modified with ferrocene. Different immobilization procedures have been carried out, the sensor operational parameters have been optimized, determining the best conditions and the analytical method for the analysis of samp...

In this investigation, the performance of a tower for absorption of sulphur dioxide gas into calcium carbonate solution has been studied. The trays had no downcomer and the tower itself was a scaled down pilot from industrial equipment. The industrial scale tower was used for clean up of 110000 m3/hr gas using 40 m3/hr alkaline solution. The study was composed of two parts. In the first section...

The main purpose of this research is the calculation of implicit prices of the environmental level of air quality in the city of Moscow on the basis of housing property prices. The database used contains records of approximately 20 thousand apartments and has been provided by a leading real estate agency operating in Russia. The explanatory variables include physical characteristics of the hous...
