Inorganic arsenic: a need and an opportunity to improve risk assessment.
This paper presents views on the current status of (inorganic) arsenic risk assessment in the United States and recommends research needed to set standards for drinking water. The opinions are those of the Arsenic Task Force of the Society for Environmental Geochemistry and Health, which has met periodically since 1991 to study issues related to arsenic risk assessment and has held workshops an...
متن کاملAssessment in E-Learning: An Opportunity to Improve and Internalize Skills, Values and Ethics
In recent years, with the expansion of virtual education, the most important challenge that educational systems face is Assessment in e-learning, which, not only have threats, but also opportunities for this system and society. In this letter to the editor, an attempt has been made to mention some of these opportunities in the three areas of teachers, learners and educational content.
متن کاملThe need for ventilators in the developing world: An opportunity to improve care and save lives
The drive to breathe is a fundamental human and biologic behavior, regulated by a complex system of checks and balances in the body. When respiratory mechanics are deregulated by injury, infection, coma, or a host of other conditions, the biologic equilibrium shifts into a state of respiratory failure. When this occurs, mechanical ventilation can be a life saving therapy. While commonplace in d...
متن کاملArsenic and inorganic arsenic compounds
Arsenic, arsenic trioxide and pentoxide, arsenous acids, arsenic acid and their salts (arsenites and arsenates) are carcinogenic substances (Carcinogen category 1) and do not, therefore, have MAK and BAT values (Greim 2002). The former TRK value (technical exposure limit) for arsenic and its inorganic compounds was 0.10 mg arsenic/m (measured as the inhalable fraction of the aerosol; calculated...
متن کاملAssessment of occupational exposure to inorganic arsenic based on urinary concentrations and speciation of arsenic.
An analytical speciation method, capable of separating inorganic arsenic (As (V), As (III] and its methylated metabolites (MMAA, DMAA) from common, inert, dietary organoarsenicals, was applied to the determination of arsenic in urine from a variety of workers occupationally exposed to inorganic arsenic compounds. Mean urinary arsenic (As (V) + As (III) + MMAA + DMAA) concentrations ranged from ...
