Spatial and temporal variation in fine particulate matter mass and chemical composition: the Middle East Consortium for Aerosol Research Study.

Ambient fine particulate matter (PM2.5) samples were collected from January to December 2007 to investigate the sources and chemical speciation in Palestine, Jordan, and Israel. The 24-h PM2.

Disappearance of heme metabolites following chelation therapy with meso 2,3-dimercaptosuccinic acid (DMSA).

A lead poisoned adult (blood lead level 384 micrograms/dL) had a specific urinary porphyrin profile of elevated porphyrins including coproporphyrin III and 5-carboxylic acid derivatives. A multilinear gradient elution, modified with an ion-pair and a reversed phase column were employed for the separation of the diagnostically important porphyrin isomers. Fluorescence detection enhanced both sensitivity and selectivity.

Lionfish string experiences of an inland poison center: a retrospective study of 23 cases.

From January 1979 through March 1988, our regional poison center, located many hundreds of miles from the nearest coastal salt water, documented 23 cases of envenomation by "Lionfish" (members of genus Pterois). All cases involved specimens which were maintained in the homes of amateur aquarists. A study of patient epidemiology showed the following: patient's sex 91.
