A study was carried out to investigate the effects of meteorological conditions on atmospheric pollutant concentrations in a complex area. In general serious pollution episodes in the urban and suburban environment are not directly caused by sudden increases in the emission of pollutants but results from unfavorable meteorological conditions, These unfavorable conditions may reduce the ability ...

Air pollutants have been documented to be associated with a wide variety of adverse health impacts in children. These include increases in mortality in very severe episodes; an increased risk of perineonatal mortality in regions of higher pollution, and an increased general rate of mortality in children; increased acute respiratory disease morbidity; aggravation of asthma, as shown by increased...

Aerosol samples of PM2.5 and PM10 in a period of intensive haze-fog (HF) events were collected to investigate the chemical characteristics of air pollution in Beijing. The air quality in HF episodes was much worse than that in nonhaze-fog (NHF) days. The concentrations of elements and water-soluble (WS) ions (K+, So4(2-), and NO3-) in HF episodes were more than 10 times higher than those in NHF...

Due to climate change and other factors, air pollution patterns are changing in several urbanised areas of the world, with a significant effect on respiratory health both independently and synergistically with weather conditions; climate scenarios show Europe as one of the most vulnerable regions. European studies on heatwave episodes have consistently shown a synergistic effect of air pollutio...

BACKGROUND Particulate air pollution episodes have been associated with increased daily death. However, there is little direct evidence that diminished particulate air pollution concentrations would lead to reductions in death rates. We assessed the effect of air pollution controls--ie, the ban on coal sales--on particulate air pollution and death rates in Dublin. METHODS Concentrations of ai...

This paper examines how the concept of 'excessive costs' has been interpreted in the implementation of industrial pollution control in the UK. Since 1984, industrial air pollution regulation in the EU has been guided by the framework concept of Best Available Technology Not Entailing Excessive Costs (BATNEEC). With the introduction of the Integrated Pollution Prevention & Control Directive in 1...

Historical monuments as architectural heritage are, economically and culturally, considered one of the key aspects for modern communities. Cultural heritage represents a country’s national identity and pride and maintains and enriches that country’s culture. Therefore, conservation of the monuments remained from our ancestors requires everybody’s serious and unremitting effort. Conservation, re...

AIMS Episodes of increased air pollution are associated with increases in hospital admissions for cardiovascular disease. Even modest acute phase responses are associated with increased risk of coronary heart disease. The study investigates whether induction of an acute phase response by exposure to air pollution may contribute to cardiovascular pathology. METHODS AND RESULTS A prospective co...

Continuous measurements of meteorological parameters, gaseous pollutants, particulate matters, and the major chemical species in PM2.5 were conducted in urban Hangzhou from 1 September to 30 November 2013 to study the potential sources and formations of PM2.5 pollution. The average PM2.5 concentration was 69 μg ̈m ́3, ~97% higher than the annual concentration limit in the national ambient air qua...
