Pathological and toxicological findings in glyphosate-surfactant herbicide fatality: a case report.

Glyphosate herbicide is promoted by the manufacturer as having no risks to human health, with acute toxicity being very low in normal use. In Thailand, however, poisoning from glyphosate agricultural herbicides has been increasing. A case of rapid lethal intoxication from glyphosate-surfactant herbicide involved a 37-year-old woman, who deliberately ingested approximately 500 mL of concentrated Roundup formulation (41% glyphosate as the isopropylamine salt and 15% polyoxyethylene amine; Mosanto Company).

Serum aluminium in alumina exposed workers.

This study was performed after skepticism occurred in 1994 when alumina, or aluminium oxide, was thought to be the cause of sickness and death for certain workers at the Northern Industrial Park, Lumphun province, Thailand. Zeeman-graphite furnace atomic absorption spectrometric method has been developed to quantify the aluminium (Al) levels in the serum of 399 workers and 500 blood donors. The results showed that Al levels in the directly (n = 62) exposed workers was significantly different from the indirectly exposed (n = 130) and non-exposed (n = 207) workers and donors.
