Physiologically based pharmacokinetic modeling of hydrogen cyanide levels in human breath
- BiologyArchives of Toxicology
Breath analysis may be used as a rapid diagnostic method for cyanide poisoning and a preliminary physiologically based pharmacokinetic model suggests that breath HCN levels following inhalation exposure at near-lethal and lethal conditions are 0.1–1 ppm.
Inorganic Arsenic Reference Exposure Levels
Acute, 8-hour and chronic reference exposure levels (RELs) were derived for inorganic arsenic including arsine, with the most sensitive acute effects seen in mice (fetal development) whereas the mostsensitive 8-hours and chronic effects were decreased intellectual function in children.

The article presents the results of the study of sulfur-containing gases (carbon disulfide, CS2, and dimethyl sulfide, C2H6S) in the air above the sulfide tailings and in the soils in Komsomolsk…
Human continuous hydrogen cyanide inhalation predictor with a physiologically based pharmacokinetic (PBPK) model
- BiologyEnvironmental Science and Pollution Research
The HCCIP model is an effective tool for assessing risk from continuous HCN inhalation, andHCCIP extends the capabilities of air dispersion modeling, such as AERMOD or CALPUFF, to assess HCN risk from specific release sources.
Effects of Exposure to Carbon Dioxide in Potash Miners.
- MedicineAdvances in experimental medicine and biology
No significant adverse effects could be found in potash miners exposed to elevated CO2 concentrations and chronic health effects were not observed in the miners either.
Synergistic Effects of Oxygen on Phosphine and Ethyl Formate for the Control of Phthorimaea operculella (Lepidoptera: Gelechiidae)
- Chemistry, BiologyJournal of economic entomology
It was shown that atmospherically oxidized PH3 was much more effective against P. operculella than PH3 alone, demonstrating a synergistic effect for this fumigant and O2, and treatment with PH3 and high concentrations of O2 could be useful for managing the postharvest pest P.operculella.
