Eluent A was 0.1% aqueous TFA and eluent B was 0.1% TFA in organic solvent
(acetonitrile or methanol).
The ability of the synthesized organogels in the sorption of organic solvents
with different polarity was investigated afterwards.
Regarding the results presented in this study, the blend ratios of (1: 5) and (1: 4), (1: 4) would be preferable for the organic solvents
of chloroform, chlorobenzene, and o-dichlorobenzene, respectively.
Industrial hygienists assessed the levels of workplace exposure to organic solvents
in 5000 women from across the US, from one month before conception through to the first three months of pregnancy (first trimester).
Among the women with organic solvent
exposure, 12 of the fetal malformations occurred in the 75 women who had symptoms, such as eye or respiratory irritation, temporally associated with their exposure.
It may be stated that most major legislatures are attempting to control organic solvent
emissions for reasons of public health, ground level air pollution and stratospheric ozone reduction.
* Model SPD210--A large-capacity, modular system, suitable for drying aqueous and organic solvents
in large sample volumes.
Anna Karin Hedstrom, M.D., Ph.D., from the Karolinska Institutet in Stockholm, and colleagues investigated the influence of exposure to organic solvents
on MS risk, as well as a potential interaction between organic solvents
and MS risk human leukocyte antigen (HLA) genes among 2,042 incident cases of MS and 2,947 controls.
The participants were also asked whether they had been exposed to organic solvents
, painting products or varnish and whether they had ever been a smoker.
Critical analytical instruments, such as HPLC, commonly use organic solvents
. Reagent and collection vessels are often left open or ineffectively closed with films and aluminum foil, venting potentially toxic vapors to the atmosphere.
are typically present in paints, adhesives, glues, plastics and fuels (1).
