Air pollution: forest health and passive sampling

air pollution assessment in shiraz by passive sampling techniques

the air quality in shiraz was assessed based on a one-week passive sampling campaign.during the first week of the summer 2003, about 400 passive samplers were used in groups of two andthree, so that 187 sampling stations covered all of shiraz. pollutant gases including so2, no2 and btx(benzene, toluene and xylene) were sampled by diffusive sampling tubes. collected samples wereanalyzed and poll...

Air pollution and forest health: toward new monitoring concepts.

It is estimated that 49% of forests (17 million km(2)) will be exposed to damaging concentrations of tropospheric O(3) by 2100. Global forest area at risk from S deposition may reach 5.9 million km(2) by 2050, despite SO(2) emission reductions of 48% in North America and 25% in Europe. Although SO(2) levels have decreased, emissions of NO(x) are little changed, or have increased slightly. In so...

Air Pollution and Health

Air pollution and health.

OBJECTIVE To review the effects of air pollution on health, with special reference to data obtained locally in Hong Kong. DATA SOURCES Medline literature search (1960-1999), websites of the World Health Organization and Environmental Protection Department, Hong Kong, and a report from the Sub-Working Group on the Review of Hong Kong's Air Quality Objectives, 1999. STUDY SELECTION Key words ...

Air pollution and children's health.

Children's exposure to air pollution is a special concern because their immune system and lungs are not fully developed when exposure begins, raising the possibility of different responses than seen in adults. In addition, children spend more time outside, where the concentrations of pollution from traffic, powerplants, and other combustion sources are generally higher. Although air pollution h...
