Sentence examples for pollution variability from inspiring English sources

The researchers assembled readily available data from the National Air Pollution Surveillance monitoring network in Canada and devised models to predict ambient concentrations of five pollutants at a national scale while capturing within-city pollution variability.

National exposure models were required by Carex Canada to produce population exposure assessments that captured both between-city and within-city pollution variability.

This suggests that PM10 and NO2 represent different characteristics of the air pollution mixture that act independently, which may be related to the source of the pollution variability.

We selected sampling locations with a location-allocation model based on pollution variability over space and on residential population density summarized elsewhere (Kanaroglou et al. 2005).

With higher maximum out door pollution, FEV1 variability between morning and afternoon dropped, and afternoon PEFR dropped.

In general, differences in estimated IHD mortality rates between high- and low-walkability neighborhoods were larger when using the alternate models; therefore, base-case results reported above may be conservative estimates (i.e., underestimates) of air pollution spatial variability.

The paper presents the use of passive sampling in combination with factor analysis to assess the presence of anthropogenic organic pollutants, and to determine the type of pollution and seasonal variability of contamination.

Yet, in spite the growing interest in understanding how organisms respond to global change, the joint fitness effects of water pollution and increased variability in temperature remain unclear.

Other factors of concern for the painted turtles include over-collection from the wild, released pets introducing diseases or reducing genetic variability, pollution, boating traffic, angler's hooks (the turtles are noteworthy bait-thieves), wanton shooting, and crushing by agricultural machines or golf course lawnmowers or all-terrain vehicles.

Studies on acute effects of particulate matter (PM) air pollution show significant variability in exposure-effect relations among cities.

In an examination of temporal patterns of indoor pollution, day-today variability of concentrations within individual households, although substantial, were smaller than concentration variations across households.
