The formaldehyde in a 5.00-g sample of a seed disinfectant was steam distilled, and the aqueous distillate was collected in a 500-mL volumetric flask. After dilution to volume, a 25.0-mL aliquot was treated with 30.0 mL of 0.121 M KCN solution to convert the formaldehyde to potassium cyanohydrin. 

The catastrophy of Minamata in Japan (1953-1960), with 55 people killed and more than 1200 poisoned, for the first time focused attention on the environmental consequences of water-soluble organometal species. In this particular case, it was mercury-containing waste water that had access to marine organisms [3 a, 20]. Fish, particularly, accumulates mercury, up to 250 ppb. In another case (Iraq, 1970-1971), the seed disinfectant ethylmercury p-toluenesulfonic anilide (4) had been applied to wheat and caused severe poisoning of consumers.
