The phrase "average pollution levels" is correct and usable in written English.
It can be used when discussing the typical or mean measurements of pollution in a specific area or context.
Example: "The study revealed that the average pollution levels in the city have decreased over the past decade."
Alternatives: "mean pollution rates" or "typical pollution measurements".
Field studies with personal exposure monitors have found that traditional exposures estimated from average pollution levels in a city based upon residence postal codes are inadequate for pollutants which are spatially variable [ 16] and tend to underestimate variability in exposure, in particular when a person's location is highly correlated to narrow peaks in the pollution field.
Because air pollution is influenced by the weather — for example, a stagnant air mass tends to hold any pollutants in place — it is best to look at several years of data to understand average pollution levels independent of weather patterns.
For every additional 100 micrograms of particulate matter per cubic meter above the average pollution levels in the south, the life expectancy at birth drops by three years, the researchers found.
It's unclear why people in Eastern and central Europe, with higher average pollution levels, seem to be at less risk from daily increases in air pollution.
A back-of-the-envelope calculation involving our estimates, the average pollution levels in 1997, labor force participation rates, and minimum wages in Indonesia puts a very conservative number of about ten billion USD lost as a result of this pollution episode during the year 2000 alone.
Beijing's average pollution levels in 2015 still put it well in the "unhealthy" range and far above international standards for acceptable air quality.
For example, we may want to use the measured values x t) of a pollution level in a lake at different moments of time to estimate the average pollution level; however, we do not know the exact values x t)—e.g., if one of the measurement results is 0, this simply means that the actual (unknown) value of x t) can be anywhere between 0 and the detection limit (DL).
Researchers commonly use the average concentrations across monitors to obtain one average pollution level in case cross-over analysis [ 25- 28].
Mean pollution levels and average levels for the meteorological variables were calculated for the first trimester of gestation for each pregnancy if fewer than 20 days of daily averages were missing during the period.
Instead of analysing either the average health risk given by average city pollution levels or analysing a limited number of citizens' mobility, we are now in a position to analyse the probability distribution density of individual risk for relevant diseases.
Correlations between estimated annual average air pollution levels at birth and current addresses for the same pollutant were moderate to high (r = 0.26 0.88) depending on the cohort and pollutant.
