Lead exposure of the child population in Greece.

Lead exposure of the child population was studied in three different areas in Greece: Kalamata which is a rural area of Southern Greece; Tavros, a district of Athens with a considerable industrial activity; and Lavrion, a small city near Athens where a lead-zinc mining and smelting industrial complex has existed for more than 90 years. The results were evaluated with respect to a number of individual, social and environmental variables (i.e. smelter, occupation of the father) especially those concerning the area of Lavrion which is the most heavily polluted area in Greece. The results of this study can be considered as an index for the extent of the lead pollution problem in the named areas of Greece.

[Cyanide poisoning. Priority to symptomatic treatment. 25 cases].

A retrospective study of 25 cases of cyanide poisoning has brought to light the following points: cardiorespiratory arrests are frequent (7/25) and often inaugural; in severe intoxications (7/25), deep metabolic acidosis is the rule, and cyanide poisoning should always be suspected in cases of coma with severe acidosis; mild intoxications are frequently symptomless. Anxiety and agitation should not be considered as evidence of cyanide poisoning; they are merely due to fear in most cases. The present treatment of acute cyanide poisoning relies basically on symptomatic measures: sodium bicarbonate, cardiac massage and, above all, assisted ventilation with 100% oxygen. Our experience does not support the concept of a lethal cyanide blood level when patients can rapidly be transferred by a medical team to an intensive care unit. Survival depends more on prompt medical care than on the accessibility to sophisticated antidotes.

Statistically significant hematopoietic effects of low blood lead levels.

Blood lead (Pb-b) concentrations, hematocrit (Ht), and hemoglobin (Hb) were determined in three groups of men working in different parts of a cable-producing factory. All three parameters examined, i.e., Pb-b, Ht, and Hb, in the above groups were found to be within "normal" limits. However, within each group of men studied, there was a statistically significant negative correlation between Pb-b concentrations and Ht and Hb values. This finding indicates that any increase in Pb-b concentration, even within the "normal" values, may result in a decrease of hematocrit and hemoglobin values of the same subjects.
