Fluctuating asymmetry and condition in golden shiner (Notemigonus crysoleucas) and channel catfish (Ictalurus punctatus) reared in sublethal concentrations of isopropyl methylphosphonic acid.
Environ. Toxicol. Chem. 25(1) , 58-64, (2006) Fluctuating asymmetry (FA; small, random differences between the left and right sides of a bilateral character) has been related to embryological stress during development. Some populations exhibit positive relations between FA and exposure to toxicants durin... |

Acute toxicity of isopropyl methylphosphonic acid, a breakdown product of sarin, to eggs and fry of golden shiner and channel catfish.
J. Toxicol. Environ. Health A 68(2) , 141-9, (2005) Several countries, including the United States, have agreed to destroy stockpiled chemical warfare agents in accordance with the Chemical Weapons Convention Treaty of 1993. Sarin is one of many chemical warfare agents (CWA) designated for destruction. In the ... |

The comparative metabolism of diisopropyl methylphosphonate in mink and rats.
Arch. Environ. Contam. Toxicol. 27(3) , 420-5, (1994) This study reports the metabolism of carbon-14labeled diisopropyl methylphosphonate (DIMP) in mink and rats, undertaken to better understand the dose-related mortality reported for mink in a previous study. In both male and female mink and rats, DIMP was rapi... |

Detection of metabolites of toxic alkylmethylphosphonates in biological samples.
Biol. Mass Spectrom. 20(11) , 717-23, (1991) The major metabolites and breakdown products of some toxic organophosphonates are their respective alkymethylphosphonic acids. These acids ionize at physiological pH and are not amenable to gas chromatographic analysis in their underivatized forms. Their dete... |
