Non-chromatographic speciation of toxic arsenic in fish.
A rapid, sensitive and economic method has been developed for the direct determination of toxic species of arsenic present in fish and mussel samples. As(III), As(V), dimethylarsinic acid (DMA), and monomethylarsonic acid (MMA) were determined by hydride generation-atomic fluorescence spectrometry using a series of proportional equations without the need of a chromatographic previous separation...
متن کاملApplications of goethite nanoparticles for removal of arsenic and mercury toxic ions from synthetic wastewater
Contamination of water resources with toxic elements is one of the challenges of thetoday's world. In this research, application of Goethite nanoparticles in removingcontamination of arsenic and mercury from synthetic wastewater in a batch mode isinvestigated. For this purpose, the effect of different factors including pH, adsorbent dosage,contac...
متن کاملDynamical Modeling of Toxic and Non-toxic Phytoplankton Competition
The study of the competitive outcome associated with two consumers of the same resource, algae, is investigated under asymmetric intraguild interactions and carrying capacities that are a function of resource (algae) availability at any time. The mathematical model is motivated by our understanding of the interactions of genus Protoperidinium (toxin producing) and Heterocapsa (non-toxic produci...

15 صفحه اولThyroid cancer in toxic and non-toxic multinodular goiter.
BACKGROUND Many authors have claimed that hyperthyroidism protects against thyroid cancer and believed that the incidence of malignancy is lower in patients with toxic multinodular goiter (TMG) than in those with non-toxic multinodular goiter. But in recent studies, it was reported that the incidence of malignancy with TMG is not as low as previously thought. AIM To compare the thyroid cancer...
