The phrase "a set of pollutants" is correct and usable in written English.
It can be used when referring to a collection or group of different types of pollutants, often in environmental or scientific contexts.
Example: "The study focused on a set of pollutants that were found in the river, including heavy metals and organic compounds."
Alternatives: "a group of pollutants" or "a collection of pollutants".
Significant associations were also identified for MDT [3, 3] and MDT [3, 1], day types that reflect extreme concentrations for either a collection of primary pollutants (CO, NO2, NOX, EC, and OC) or a set of secondary pollutants (O3, NH4, and SO4).
Secondary sources refer to indoor chemistry that transforms a set of indoor pollutants, emitted from primary sources or transported from outdoors, to a new set of indoor pollutants, as discussed below.
By testing a set of air pollutants, however, the possibility that some effects might have occurred by chance cannot be excluded.
A Multivariate ANOVA was also conducted on a set of all pollutants combined (Sum 36 PCBs, HCB, pp-DDE, pp-DDT, Sum 10 PBDEs, Sum 3 HBCDs and nine metals).
However, a multivariate ANOVA conducted on a set of all pollutants combined (Sum 36 PCBs, HCB, pp-DDE, pp-DDT, Sum 10 PBDEs, Sum 3 HBCDs and nine metals) indicated statistically significant differences (F = 2.7; df = 20; p = 0.022).
A Multivariate ANOVA (MANOVA) was conducted on a set of all pollutants combined (Sum 36 PCBs, HCB, pp-DDE, pp-DDT, Sum 10 PBDEs, Sum 3 HBCDs and nine metals).
Other strengths of this study include assessment of a comprehensive set of pollutants, cohorts covering a wide range of exposures, large numbers of participants, common information about potential confounders, and comparability of health analysis methods.
These enzymes, involved in the conjugation of reduced glutathione to electrophilic centers on a wide variety of substrates, contribute to the detoxification of endogenous compounds (e.g. peroxidised lipids) as well as xenobiotics, and an increased GST activity has been observed after exposure to a broad set of pollutants.
Consequently, it may not be feasible to detect all pairwise (and higher order) interactions given a large set of pollutants.
