Isocyanates include compounds classified as potential human carcinogens and known to cause cancer in animals. This first property makes electrospun material suitable for activities requiring a high degree of physical contact, such as providing sites for chemical reactions, or the capture of small sized particulate material by physical entanglement filtration. For instance, the preservative thiomersal used in vaccines is toxic, but the quantity administered in a single shot is negligible. Only the dose makes a thing not a poison"[11] Indeed, 2,4-D is not a poison, but classified as "harmful" (EU). The Class II Type A2 biosafety cabinet is the most common cabinet on campus. It may also be applied colloquially or figuratively, with a broad sense.. The small fiber diameters cause slip flows at fiber surfaces, causing an increase in the interception and inertial impaction efficiencies of these composite filter media. By the principle of entropy, chemical contamination is typically costly or infeasible to reverse, unless specific chelating agents or micro-filtration processes are available. Two common cases of acute natural poisoning are theobromine poisoning of dogs and cats, and mushroom poisoning in humans. Leather is a strong, flexible and durable material obtained from the tanning, or chemical treatment, of animal skins and hides to prevent decay.The most common leathers come from cattle, sheep, goats, equine animals, buffalo, pigs and hogs, and aquatic animals such as seals and alligators..
