چکیده
a chromium electroplating bath with the ability to produce homogenous mist was used to evaluate parameters influencing hexavalent chromium (cr+6) mist sampling methods. the results of 48 cr+6mist samples collected using the u.s. national institute for occupational safety and health method 7600showed that cr+6concentration was higher: (1) for sampling by closed-face filter cassettes than for sampling by open-face filter cassettes (p

متن کاملDesign and Performance of Chromium Mist Generator
O gerador de névoa crômica homogênea é uma ferramenta essencial para pesquisas e avaliações científicas, sobre a poluição do ar e seus sistemas de controle. O objetivo desta pesquisa foi projetar e construir um gerador de névoa de cromo e estudar alguns fatores, como altura de amostragem e distâncias entre amostras, em amostragens lado a lado, com o método de amostragem de névoa crômica. O gera...
متن کاملDevelopment and evaluation of orally disintegrating tablets of Pramipexole using full factorial design
Pramipexole is the mostly prescribed drug in patients with Parkinson disease. The incidence of Parkinson disease is related to aging and mostly developed in elderly people with difficulty in swallowing or dysphagia. In the current study we aimed to develop an orally fast disintegrating tablet (ODT) of pramipexole as a preferable alternative in geriatric patients. Hence, the fast disintegration ...
متن کاملAutomated Ground-Water Sampling and Analysis of Hexavalent Chromium using a “Universal” Sampling/Analytical System
The capabilities of a “universal platform” for the deployment of analytical sensors in the field for long-term monitoring of environmental contaminants were expanded in this investigation. The platform was previously used to monitor trichloroethene in monitoring wells and at groundwater treatment systems (1,2). The platform was interfaced with chromium (VI) and conductivity analytical systems t...
متن کاملCarcinogenicity of hexavalent chromium.
Hexavalent chromium (Cr(VI)), a commonly used industrial metal, is a well known human lung carcinogen. Epidemiology and animal studies suggest that the particulate Cr(VI) compounds, specifically the water insoluble compounds, are the more potent carcinogens; however, the carcinogenic mechanism remains unknown. Here we summarize recent Cr(VI)-induced human tumour, in vivo, cell culture and in vi...

Publication 1. A. Manceau et al, “Quantitative Zn speciation in smelter-contaminated soils by EXAFS spectroscopy,” Am. J. Sci. (in press, 2000). Figure 3 (top) Soil samples were taken at several depths from a contaminated site. (bottom) Model compounds derived from polarized-EXAFS data at the ESRF and μ-EXAFS data at the ALS provide a good fit with powder-EXAFS spectra from a soil sample, there...
