Cyanide Effects on Plants eHow

03-03-2021  Plants that have metabolized large amounts of cyanide can be hazardous to animals who eat those plants. Cyanide poisoning of livestock by way of cyanide buildup in grasses and other plants cultivated for cattle grazing have been so problematic that botanists have developed strains of cattle-grazing plants resistant to the buildup of large amounts of cyanide.

Plant Defense Mechanisms Boundless Biology

Many plants have impenetrable barriers, such as bark and waxy cuticles, or adaptations, such as thorns and spines, to protect them from herbivores. If herbivores breach a plant’s barriers, the plant can respond with secondary metabolites, which are often toxic compounds, such as glycol cyanide, that may harm the herbivore.

Hydrogen Cyanide - an overview ScienceDirect

Cyanide does not bind to soil or plant material, but can mix with water. Contaminated water can be treated with ozone, hydrogen peroxide, or calcium/sodium hypochlorite bleach. Rescue personnel should wear boots, gloves, goggles, full protective clothes, and a self-contained positive pressure breathing apparatus as the potential for secondary contamination is high ( AAR, 2000 ).

Sodium cyanide - Wikipedia

Sodium cyanide is a poisonous compound with the formula Na C N.It is a white, water-soluble solid. Cyanide has a high affinity for metals, which leads to the high toxicity of this salt. Its main application, in gold mining, also exploits its high reactivity toward metals.It is a moderately strong base.When treated with acid, it forms the toxic gas hydrogen cyanide:

CDC Facts About Cyanide

Cyanide is released from natural substances in some foods and in certain plants such as cassava, lima beans and almonds. Pits and seeds of common fruits, such as apricots, apples, and peaches, may have substantial amounts of chemicals which are metabolized to cyanide. The edible parts of these plants contain much lower amounts of these chemicals.
