In response, substances continue to have their chemical composition “tweaked” to try to skirt regulation [3], creating what has been described as a “cat-and-mouse game between legislation and clandestine laboratories…with new designer stimulants replacing those outlawed almost as soon as ...
The goal of this paper is to both understand and depathologize clinically significant mental distress related to criminalized contact with psychoactive biotic substances by employing a framework known as critical political ecology of health and disease f
Atmospheric organic aerosol (OA) are considered as a significant contributor to the light absorption of OA, but its relationship with abundance, composition and sources are not understood well. In this study, the abundance, chemical structural characteri
Permeabilities of O2 and N2 were measured at 23°C for poly(vinyl alcohol)(PVA) membranes swollen to 30-80wt% with water or aqueous solutions of urea ((NH2)2CO), tetraethylammonium chloride ((C2H5)4NCl, TEACl) and sodium tetraphenylboride (NaB(C6H5)4, NaTPB). It was found that with...
The concentrations of 652, 852, 1052 and 1252 FTOH (SFTOHs) in air varied from 5.6 to 34 pg m23 with a mean value of 14 pg m23 (Figure 3), which is lower than those in Toronto (mean 79.5 pg m23)21, Hamburg (from 32 to 204 pg m23)22, and the North Sea (84 pg m23)...
