In surface water you can find dependent on the study site several organophosphate esters, i.e. organophosphorous pesticides such as diazinon and chlorpyrifos. There are numerous publications on that topic.

Concerning your PAH mix, I think it's the 18 EPA PAH-mix (?).

Thanks Dr Roos,

I mean this item : Fenthion Dimethoat Monocrotopho Permethrin Bioallethrin Primiphose Pyrozophose

Regards

There are a lot of researches on this topic

You are aware that organo-phosphorus is part of the pesticides we use. Consequently, this finds its way into water sources through surface run-off from lands sprayed with the pesticide.
