Therefore, restriction of sudden and huge changes in biodiversity due to climatic changes such as global warming and pollution are few of the challenging issues for eco-physiologists (Harvell et al., 1999; Leaf, 1989; Epstein, 1999; Tollefson, 2012).
Forest defoliation and discoloration have been monitored extensively in Europe over the past decade, yet the number of published studies seeking to interpret these data in light of environmental parameters such as lithology and airborne pollution are few.
There were few air pollution effects in the first month and in the three months preceding birth.
There are few studies reporting indoor air pollution exposures for asthmatic children in inner-city environments, and only rarely have studies reported on the combined exposures to allergens and indoor air pollutants in asthmatic children.
This paper examines the associations between average daily particulate matter less than 10 microns in diameter (PM10) and temperature with daily outpatient visits for respiratory disease including asthma, bronchitis, and upper respiratory illness in Anchorage, Alaska, where there are few industrial sources of air pollution.
(Any kind of charcoal, however, releases more particulate matter than propane, which makes charcoal a greater contributor to air pollution. There are few easy choices in environmental analysis).
Currently, there are few studies on the effects of air pollution or NGD on birth outcomes.
There are few studies exploring a potential causal role of air pollution in DM development.
There are few epidemiologic data on the relation of prenatal air pollution exposure and the risk of oral clefts.
First, they provide direct evidence of air pollution effects in areas for which there are few studies.
