Results and discussion
- Clinical signs:
- Acute poisoning in humans The lethal dose of organolead compounds for human beings is not precisely known. On the basis of sixteen cases, an estimated minimum lethal dose of 15 ml TEL orally, with initial symptoms appearing at 6 ml. Grandjean gives an LD50 value of 250 mg/kg bodyweight for TEL in human beings. Up to 1984, 150 cases of fatal TEL poisoning had been reported.
Cleaning operations on petrol storage tanks frequently give rise to cases of poisoning. A full review and analysis of such cases is given in the BUA Draft Report. The latency period between acute exposure to TEL and the appearance of the first symptoms varies from a few hours to ten days, depending on the severity. The first signs of poisoning are generally loss of appetite (anorexia), nausea and vomiting, sleeplessness, weakness, headache, aggression, depression, irritability, diffuse body aches, tremor, hyperactivity, exaggerated proprioceptive muscular reflexes, muscular asthenia, difficulty in concentrating and remembering, confusion, and unusual sensory hallucinations. If larger quantities are absorbed orally, gastro-intestinal symptoms, such as vomiting, abdominal pain and diarrhoea, predominate. Hours or even days can pass after the onset of the first symptoms before the condition of the victim becomes critical. Acute psychoses, convulsions, delirium, fever and coma then occur. Other symptoms such as hypothermia, hypotonia and bradycardia may also be seen. The longer the symptom-free period after acute poisoning lasts, the more favourable the prognosis. Even after the most severe clinical symptoms, virtually complete recovery is possible within two to six months. A full review of the available data on work on acute poisoning is contained in the BUA Draft Report on TML and TEL.

Acute poisoning in humans
The lethal dose of organolead compounds for human beings is not precisely known. On the basis of sixteen cases, an estimated minimum lethal dose of 15 ml TEL orally, with initial symptoms appearing at 6 ml. Grandjean gives an LD50 value of 250 mg/kg bodyweight for
TEL in human beings. Up to 1984, 150 cases of fatal TEL poisoning had been reported.
Cleaning operations on petrol storage tanks frequently give rise to cases of poisoning. A full review and analysis of such cases is given in the BUA Draft Report.
The latency period between acute exposure to TEL and the appearance of the first symptoms varies from a few hours to
ten days, depending on the severity. The first signs of poisoning are generally loss of appetite (anorexia), nausea
and vomiting, sleeplessness, weakness, headache, aggression, depression, irritability, diffuse body aches, tremor,
hyperactivity, exaggerated proprioceptive muscular reflexes, muscular asthenia, difficulty in concentrating and
remembering, confusion, and unusual sensory hallucinations.
If larger quantities are absorbed orally, gastro-intestinal symptoms, such as vomiting, abdominal pain and diarrhoea, predominate.
Hours or even days can pass after the onset of the first symptoms before the condition of the victim becomes
critical. Acute psychoses, convulsions, delirium, fever and coma then occur. Other symptoms such as hypothermia,
hypotonia and bradycardia may also be seen. The longer the symptom-free period after acute poisoning lasts, the more
favourable the prognosis. Even after the most severe clinical symptoms, virtually complete recovery is possible
within two to six months.
A full review of the available data on work on acute poisoning is contained in the BUA Draft Report on TML and TEL.
