Biological agents lethality

TICs are threats to water systems, but are not as problematic as chemical or biological agents. Consider cyanide with a lethal dose of 25 mg. To contaminate the reservoir mentioned above would require 25 x 200 x 10 mg, or roughly 5,000 kg (5 tons). Dimethyl mercury is lethal at 400 mg more than 50 tons would be required. Of course, it is possible to contaminate a small reservoir or simultaneously a group of several reservoirs. 

America s participation in germ warfare research took an abrupt turn when, on November 25, 1965, President Richard Nixon proclaimed that the U.S. shall renounce the use of lethal biological agents and weapons, and all other methods of biological warfare. The U.S. will confine its biological research to defensive measures. In 1972, the United States, the Soviet Union, and more than 100 nations...

Infection control issues raised by these biological agents of concern raise serious threats to health care professionals, including clinical and laboratory personnel who may encounter patients or clinical specimens suspected of harboring highly lethal bacteria or viruses. 

Brine shrimp lethality and cell line culture assays are the most frequently used in estimating preliminary toxicity potential of different biological agents. In this study, brine shrimp and CellTiter-Blue Cell Viability Assays were used in evaluating the cytotoxity potential of different plant extracts. 

Two members of the Minnesota Patriots Council were convicted in 1995 for planning to use a lethal biological agent against U.S. marshals and Internal...
