HEALTH SUPERVISION OF ORGANIC SOLVENT HANDLERS

California handlers describe marketing issues for organic kiwifruit

O fruit production and marketing is a fast-growing niche that is beginning to utilize traditional channels to reach an expanding market segment. As organic production grows and consumer preferences change, marketing practices will evolve. Many California commodities have established government-sponsored and producer-financed marketing programs that cover both organic and conventional production...

Nanopapers for organic solvent nanofiltration.

Would it not be nice to have an organic solvent nanofiltration membrane made from renewable resources that can be manufactured as simply as producing paper? Here the production of nanofiltration membranes made from nanocellulose by applying a papermaking process is demonstrated. Manufacture of the nanopapers was enabled by inducing flocculation of nanofibrils upon addition of trivalent ions.

Health effects and exposure assessment of aerosolized pentamidine handlers.

Nurses administering aerosolized pentamidine (AP) were studied to determine any effect AP may be having on their health. Exposure was determined by each nurse's self-report of treatment given as recorded in a daily log and personal and area pentamidine sampling. Outcome measures were self-reported symptoms recorded in a daily log and peak expiratory flow rates (PEFR) and cross-shift and cross-w...

Silica gel-mediated organic reactions under organic solvent-free conditions.

Silica gel was found to be an excellent medium for some useful organic transformations under organic solvent-free conditions, such as (1) the Friedel-Crafts-type nitration of arenes using commercial aqueous 69% nitric acid alone at room temperature, (2) one-pot Wittig-type olefination of aldehydes with activated organic halides in the presence of tributyl- or triphenylphosphine and Hunig's base...
