Title Inorganic fertilizers
Original title Engrais minéraux [in French]
Bibliographic information Toxicologie-Pathologie professionnelle, 1st Quarter 2004, No.142, 5p. Illus. 41 ref.
Abstract The ingestion of concentrated liquid fertilizers may severe cause severe acute poisoning due to the presence of high levels of potassium in these types of formulations. With the exception of a few cases of skin diseases and indications of mucous membrane irritation related to dusts, there are very few reports of harmful effects in occupational settings. Some fertilizer formulations containing calcium cyanamide may give rise to an antabuse effect. Excessive use of inorganic fertilizers results in the pollution of the water table by nitrates, which may then find their way into the water supply. Nitrates have been suspected of causing methaemoglobinaemia accidents in newborn children and cancers among the general population. However, their human toxicity has been largely overestimated. Methaemoglobinaemia in newborn children has been established to be caused by the bacterial pollution of water. It has not been possible to demonstrate any relationship between the long-term consumption of nitrate-rich water and cancers among the general population.
