Every human activity can be looked at from the point of view of risks and benefit, though we often have difficulty in deciding on an agreed definition for these terms. For risks of death and disease a few principles can be formulated, keeping in mind as our standard examples the risks of ski-ing, smoking, pregnancy, accidents to workers on a building site or in deep sea fishing, or risks in war...

Erythrosine (FD&C Red No. 3) is widely used as a coloring agent for foods, beverages, pharmaceutical preparations, and cosmetics. It has been evaluated for acceptable daily intake by the Joint FAO/WHO Expert Committee on Food Additives (see Annex 1, Ref. Nos. 8, 19 & 35) in 1964, 1969 and 1974. At the 18th Meeting (1974) of the Committee, an ADI of 0 2.5 mg/kg body weight was allocated. Toxicol...

of the 27 nitrofuran derivatives tested had mutagenic effects on E. coli, but none of them had mutagenic effects on S. typhimurium. Twenty-five compounds had DNA-modifying effects on E. coli, and 24 compounds had effects on the DNA of S. typhimurium. Fifteen of the 27 compounds are known to be carcinogenic. Fourteen of these 15 carcinogenic derivatives had mutagenic effects on E. coli and DNA-m...

This study investigated joint effects of maternal prenatal smoking and parental history of antisocial behavior on physical aggression between ages 17 and 42 months in a population sample of children born in Québec (N = 1,745). An analysis of variance (ANOVA) showed significant main effects of maternal prenatal smoking and a significant interaction between maternal prenatal smoking and mother's ...

Aflatoxins are well recognized as a cause of liver cancer, but they have additional important toxic effects. In farm and laboratory animals, chronic exposure to aflatoxins compromises immunity and interferes with protein metabolism and multiple micronutrients that are critical to health. These effects have not been widely studied in humans, but the available information indicates that at least ...

The paper presents a coaxial-like sensor operating in the 20 Hz-2 MHz frequency range used to determine the electrical properties of selected liquids of low electrical conductivity. Examined materials included low-concentrated aqueous solutions of potassium chloride, sodium chloride and trisodium citrate, which are common food additives. Impedance spectra of the measurement cell filled with par...
