I have developped in 2003 a filter sorbant aiming to specifically disolve and bind the fatty (lipophylic) fraction of airbourne micro/submicro particular matter (PM2.5, PM1, PM0.1). Analyses for traces PCDD/F and DL-PCB's used as general indicators for POPs (persitant organic pollutants) made by a certified lab have shown significant amounts found in a "high indoor air quality house" (according to a VOC, HAP, Formaldehyde and Nox assessment), at levels much higher than what could be expected. These (preliminary) analysis results appeared to contradict the conclusion of than current epidemiological data giving mean human respiratory exposure only 5% vs food exposure around 95%. My question is about the metrological protocols of airbourne POPs made on mostly hydrophilous sampling media with strong desorpion that could determine strong potential biaises over analytical results. I take into account the endocrin disruptive properties of cumulative cocktails of POP traces with significant public health stakes.
My question is therefore "Are lipophylic fraction of fine and ultrafine airbourne particles efficiently taken in account in current air quality assessments, noticably vs POPs ?"
Note1: I'm a botanist, not specialised in pollutant / air quality chemestry nore epidemiology, just concerned about human exposure to such endoctrine disruptors compounds, first in great herbarium/natural history collections treated untill the mid 90's with DDT, Lindane and L-PCB etc., as well as for the general population, especially pregnant women and young children.
Note2: my filtering sorbant possibly enables to provide stronger breathing protection vs such fatty pollutants - along with microparticulate lipophylous biological contaminants such as mycotoxins and possibly viruses - when applied to breathing PPE and HEPA air filters.
