Toxicological Investigations in Food

Toxicological investigations on dimethylformamide.

The boiling point is 1530 C., and it is miscible with water and some organic solvents. On boiling with water or alkali it hydrolyzes to formic acid and dimethylamine. It is more stable than formamide and can be distilled. For the present work freshly distilled dimethylformamide was used and all aqueous solutions were freshly prepared. Dimethylformamide in the atmosphere may be trapped by passin...

Pesticide residues in food—2002 Toxicological evaluations

Toxicological investigations of pollutant-related effects in Great Lakes gulls.

Reproductive failure of a number of fish-eating birds was observed on the Great Lakes in the mid-1960s to mid-1970s. The herring gull (Larus argentatus) has been used as the primary monitoring species. The low hatching success observed in this species on Lake Ontario in the mid-1970s was due to loss of eggs and failure of eggs to hatch. Egg exchange experiments demonstrated that this was due bo...

Value of emergency toxicological investigations in differential diagnosis of coma.

Out of 208 cases of coma of unknown aetiology referred to the poisons unit of this hospital during 1978 for emergency toxicological investigations, 108 were found to be due to self-poisoning medical conditions, mainly neurological, accounted for coma in 90 patients; the cause was not ascertained in the remaining 10 cases. More than one preparation had been ingested by 58 (54%) of the poisoned p...
