[Presence of bacterial endotoxins in drinking and bottled water, with monitoring of eventual contaminations].

83 samples of drinking water of different source were examined with LAL-test, valuing some characteristics of the water (bacterial count, Coliform, pH, dissolved CO2) which might influence the test. Quantity higher than 0.5 ng/ml of endotoxin were detected in 40 of 44 mineral water samples and 37 of 39 tap water samples. The results are discussed.
