“Statistics is the grammar of science” – Karl Pearson.

Techniques in multivariate statistics are used by a wide variety of investigations in environmental forensics but many investigations only put emphasis on the outcome of a 𝙨𝙞𝙣𝙜𝙡𝙚 multivariate statistic that the expert has familiarity with using.

And it is surprisingly rare for studies to show a detailed understanding of the uncertainties created by 𝙢𝙪𝙡𝙩𝙞𝙥𝙡𝙚 multivariate statistical techniques or how uncertainties in chemical analysis impact statistical modelling outputs...

As such, Chemistry Matters’ Mike Dereviankin will be at The Society of Environmental Toxicology and Chemistry (SETAC) on November 16th presenting on “𝗦𝗼𝘂𝗿𝗰𝗲 𝗮𝗽𝗽𝗼𝗿𝘁𝗶𝗼𝗻𝗺𝗲𝗻𝘁 𝗼𝗳 𝗣𝗼𝗹𝘆𝗰𝗵𝗹𝗼𝗿𝗶𝗻𝗮𝘁𝗲𝗱 𝗯𝗶𝗽𝗵𝗲𝗻𝘆𝗹𝘀 (𝗣𝗖𝗕𝘀) 𝗶𝗻 𝘀𝗲𝗱𝗶𝗺𝗲𝗻𝘁 𝘂𝘀𝗶𝗻𝗴 𝗱𝗶𝗳𝗳𝗲𝗿𝗲𝗻𝘁 𝗿𝗲𝗰𝗲𝗽𝘁𝗼𝗿 𝗺𝗼𝗱𝗲𝗹𝘀: 𝗔 𝗰𝗮𝘀𝗲 𝘀𝘁𝘂𝗱𝘆 𝗼𝗻 𝗣𝗼𝗿𝘁𝗹𝗮𝗻𝗱 𝗛𝗮𝗿𝗯𝗼𝗿 𝗦𝘂𝗽𝗲𝗿𝗳𝘂𝗻𝗱 𝗦𝗶𝘁𝗲, 𝗢𝗿𝗲𝗴𝗼𝗻, 𝗨𝗦𝗔”

In this presentation, discrepancies between statistical models are investigated through analysis of four different receptor models (NMF, ALS, PMF & PVA) used to perform source apportionment of polychlorinated biphenyls (PCBs) in sediments from Portland Harbor.
