Example Sentences:
(1) Higher concentrations of methemoglobin in animals in the 2.500 ppm exposure group (measured after 90 days of exposure) indicated that the rate of oxidation of heme (ferrous to ferric) increased due to exposure to arsine gas.
(2) Arsine and in general airborne arsenic compounds show the main cancer promoting characteristics.
(3) In order to examine possible species differences in response to arsine exposure, multiple inhalation studies consisting of acute (1-day), subacute (14- and 28-day), and subchronic (90-day) exposures to this agent were conducted using three different species of rodents.
(4) Fetuses weighed more than in the control group but other endpoints of developmental toxicity were not affected by arsine exposure.
(5) While the clinical picture suggested arsine or stibine poisoning, preliminary investigation of the plant revealed no obvious source of arsenic, antimony, or hydrogen gas.
(6) Hematocrit values at 24 hr after exposure decreased linearly with increasing arsine concentration in the range 5 to 26 ppmv; the hematocrit of the 26-ppmv group reached 10.5% at 24 hr, compared to 48.4% for control mice.
(7) A 1 g sample is wet washed in a 16 x 150 mm 10 mL volumetric test tube on a programmed heating block with nitric, sulfuric, and perchloric acids at up to 310 degrees C. After treatment with hydrochloric acid and potassium iodide, arsenic is reduced by sodium borohydride to arsine in a simplified continuous flow manifold.
(8) To examine these, we exposed male and female mice to 0.000, 0.025, 0.500 and 2.500 ppm arsine gas for 6 h a day, 5 days a week during a 90-day period.
(9) Concern about semiconductor workers prompted an in-depth study of arsine at the National Institute of Environmental Health Sciences to determine the hematopoietic effects of prolonged exposure to this gas.
(10) Effects on other organs were not observed, suggesting that the hematopoietic system is the primary target for arsine.
(11) At least three times more arsine than dimethylarsine was produced in soil incubated with dimethylarsinate.
(12) The number of live fetuses, mean fetal body weight, and percentages of resorptions or malformations per litter were not affected by arsine exposure.
(13) In most situations where arsine can be formed if antimony is present.
(14) After 5, 15, and 90 days of exposure, blood was collected and routine hematologic profiles were performed to document the effects of arsine gas on peripheral blood.
(15) The National Institute for Occupational Safety and Health (NIOSH) recommends that appropriate workpractices be implemented to reduce the risk of worker exposure to arsine (AsH3) gas.
(16) We drew a conclusion that TM-As is far less an toxic than arsine, most probably due to its in vivo conversion to TMAO.
(17) A series of eight neutral technetium(II)-99m complexes of general formula tr-[99mTcIID2X2]0, where D represents a chelating ditertary phosphine or arsine ligand and X represents a halide or pseudohalide ligand, has been prepared and characterized by HPLC comparisons to the known 99Tc analogs.
(18) This recommendation is based on several reports of worker exposure to arsine resulting in severe toxic effects or death.
(19) Among these arsines, dimethylarsine was mutagenic in WP2 (wild-type; Exc+Rec+) and WP2uvrA (uvrA-; Exc-Rec+), while trimethylarsine was not.
(20) An accuracy investigation, initiated because of conflicting analytical data on the arsenic content for some 24 drinkinig water locations in the Mojave Desert, revealed that interference with the evolution of arsine in the American Public Health Association silver diethyldithiocarbamate method caused either color enhancement or arsine suppression.
