Beeswax is an ingredient in surgical bone wax, which is used during surgery to control bleeding from bone surfaces; shoe polish and furniture polish can both use beeswax as a component, dissolved in turpentine or sometimes blended with linseed oil or tung oil; modeling waxes can also use beeswax as a component; pure beeswax can also be used as ...
The best-known animal wax is beeswax, used in constructing the honeycombs of beehives, but other insects also secrete waxes. A major component of beeswax is myricyl palmitate which is an ester of triacontanol and palmitic acid. Its melting point is 62–65 °C (144–149 °F). Spermaceti occurs in large amounts in the head oil of the sperm whale.
The metabolism of bees and humans is sufficiently different that bees can safely collect nectars from plants that contain compounds toxic to humans. The honey produced by bees from these toxic nectars can be poisonous if consumed by humans. In addition, natural processes can introduce toxic substances into honey produced from nontoxic nectar.
Toxicity is the degree to which a chemical substance or a particular mixture of substances can damage an organism. [1] Toxicity can refer to the effect on a whole organism, such as an animal, bacterium, or plant, as well as the effect on a substructure of the organism, such as a cell (cytotoxicity) or an organ such as the liver (hepatotoxicity).
Bone wax as a sterile preparation for surgery. Bone wax is a waxy substance used to help mechanically control bleeding from bone surfaces during surgical procedures.. It is generally made of beeswax [1] with a softening agent such as paraffin or petroleum jelly and is smeared across the bleeding edge of the bone, blocking the holes and causing immediate bone hemostasis through a tamponade effect.
Bees that collect pollen and nectar from grayanotoxin-containing plants often produce honey that also contains grayanotoxins. [ 3 ] [ 11 ] This so-called " mad honey " is the most common cause of grayanotoxin poisoning in humans.
The acute toxicity of pesticides on bees, which could be by contact or ingestion, is usually quantified by LD 50.Acute toxicity of pesticides causes a range of effects on bees, which can include agitation, vomiting, wing paralysis, arching of the abdomen similar to sting reflex, and uncoordinated movement.
Pesticide poisoning is an important occupational health issue because pesticides are used in a large number of industries, which puts many different categories of workers at risk.
