So sad that the country is politics-wise disgusting and ruined.Alaska is surely amazing and it would be great to visit one day. Imagine though all the exploring potential of Siberia.

Lack of standardized methods and still a new area of measuring?
At least in the chemistry side of it and coming with a relatively lightweight analytical chemistry background (so I don't really know anything) I think part of the problem with analysis techniques regarding food matrices is that they are reeally complex and obviously they vary a lot depending on what type of food product is looked at. One of the workarounds is the octanol-water partition coefficient for approximation of water and fat affinity of a compound. Again, not really valid for particle type of analysis.
Going further down in food matrix known chemical's analysis, I don't know if there is any standardized analysis methods of microplastics or plasticizer analysis from food products, probably there is but since the sample is quite complex there would probably have to be an internal standard compound that is somewhat similar to the target compound but differentiable from the target analytes and is added to the sample before any sample preparation is made and then the measured analytes are compared to this internal standard compound's measured value to give a relative response. This is very basic stuff and everything but adds to the complexity of it and is kind of laborious.
