    They address concentrations varying among sites and comparative to urban areas. They also did other tests besides what you mentioned. Note:

    Time- and spatially integrated samples of I/SVOCs were collected during box flight segments (for example, Fig. 1A) and downwind transects and analyzed by means of gas chromatography on both unit-resolution and high-resolution mass spectrometers [gas chromatography–electron ionization–mass spectrometry (GC-EI-MS) and gas chromatography–time of flight (GC-ToF)], which revealed abundant complex mixtures of I/SVOCs near both surface mining and in situ facilities (Figs. 2 and 3). IVOCs (C12 to C18) and SVOCs (C19 to C25) were uncharacteristically abundant relative to VOCs (Fig. 1E) and were observed around various facilities, as shown in selected flight samples in Fig. 2A (additional examples are available in figs. S6 and S7). The relative abundances and composition varied between and around facilities, with maxima ranging from C17 to C22 (Fig. 2A, figs. S8 and S9, and tables S5 and S6), which may suggest varying on-site sources and emissions pathways. There are stark differences in the observed concentrations when compared with that of urban areas.

    Emphasis added to the last sentence mine. Why shill for oil at the expense of your own health?

      Well yes, I read enough of the article to understand this is what they meant but also that there was large unexplained variations (noise) so I just gave up. I don’t have the resources, knowledge and the time to conduct a good, complete analysis.

      Why shill for oil at the expense of your own health?

      Now this is a multi-billion dollar question and before they shut down the tar sands, many more studies will be made. So, it’s not for me to decide and we will have the opportunity to see more in this battle.

      Anyway, thanks for your interest, take care.
