10 of the Most Dangerous Chemicals in the World The most potent non-peptide based poison known. Batrachotoxin gained fame though its use in poison darts made from frog excretions. The frogs themselves don't produce the toxin directly, but through digestion of Melyrid beetles the frogs eat. Top image from Shutterstock with chemical structures from CC sources.

BHA and BHT: A Case for Fresh? BHA or butylated hydroxyanisole [pdf] is a synthetic antioxidant that is used to prevent fats in foods from going rancid and as a defoaming agent for yeast. First synthesized in the late 1940s, the compound began being used as a food additive around 1947. BHT or butylated hydroxytoluene [pdf] also stabilizes fats and is used to retain food smell, color and flavor. It too appeared on the synthetic chemical scene in the late 1940s and was used as a food additive beginning in 1954 [pdf]. (See also here.)

This site is no longer maintained and has been left for archival purposes Bacillus thuringiensis. B. thuringiensis (commonly known as 'Bt') is an insecticidal bacterium, marketed worldwide for control of many important plant pests-mainly caterpillars of the Lepidoptera (butterflies and moths) but also mosquito larvae, and simuliid blackflies that vector river blindness in Africa.. thuringiensis strains produce two types of toxin. The main types are the Cry (crystal) toxins, encoded by different cry genes, and this is how different types of Bt are classified. The second types are the Cyt (cytolytic) toxins, which can augment the Cry toxins, enhancing the effectiveness of insect control.

Nitrobenzene Nitrobenzene is prepared by nitration of benzene with a mixture of concentrated sulfuric acid, water, and nitric acid.This mixture is sometimes called mixed acid..The production of nitrobenzene is one of the most dangerous processes conducted in the chemical industry because of the exothermicity of the reaction (δ H = −117 kJ/mol). World capacity for nitrobenzene in 1985 was about 1.7×10 6 tonnes.his mixture is sometimes called mixed acid..

About ethylene Ethylene gas (C2H4) is a natural growth hormone that is produced by plant tissue as well as by the combustion of synthetic materials. It is the only member of its class and has the simplest structure of all plant growth substances.Unlike most plant hormone compounds, ethylene is a gaseous hormone.Ethylene is not harmful or toxic to humans; however, at extremely high concentrations it is combustible. Its impact on the post harvest industry is tremendous because it is active at very low concentrations and affects plants in many different ways.nlike most plant hormone compounds, ethylene is a gaseous hormone.
