Similarly, plastic containers, concrete or asbestos tanks,
asphalt resin coated tanks, stainless steel stills or wood casks are
heat treated and used for processing, aging, storing or transporting
drinks like Cachacas for which direct correlation between contamination
levels and storage vessels’ nature (glass jugs and plastic
tank) was established. Five and Six ring PAHs were found associative
to cachacas stored in poly-ethylene tank only whereas low
molecular weight PAHs were found in glass jugs stored drink
(Machado et al., 2014).
