Biowarfare is the intentional use of microorganisms, and toxins, generally of microbial, plant or animal origin to produce disease and death in humans, livestock and crops. The. attraction of bioweapons in biowarfare and bioterrorism is attributed to easy access to a. wide range of disease-producing biological agents, to their low production costs, to. their non-detection by routine security systems, and to their easy transportation from.

Copper is one of the most important metals. Copper is reddish with a bright metallic lustre. It is malleable, ductile, and a good conductor of heat and electricity (second only to silver in electrical conductivity).Its alloys, brass and bronze, are very important.Monel and gun metals also contain copper.opper metal is not particularly reactive and indeed is found as the free metal (native) on occasion. Copper sulfate is [Cu(SO 4)(OH 2) 4 ].H 2 O in the crystalline state; it is particularly well known and was often called blue vitriol.
