[Food contamination: a problem of pediatric interest].

The application of technology in the production, processing, preservation and transport of food has led to a well known consequence: the presence in the foods of undesirable substances and chemicals, that is to say "the contaminants of feeding". In this study the authors report the main groups of contaminants as the mycotoxins, nitrates, pesticides, methylmercury, lead, cadmium etc., relating for everyone of them the harmful effects for the health of human being, of which they have come to know mostly for some episodes of acute poisoning occurred in several countries in the world. They relate also the hypothetical effects of a chronic exposure to low levels of contamination, mostly if the fetuses and infants come to be exposed to these contaminants for the peculiar embryo genetic and evolutive situation that characterizes them.

Food contamination with polychlorinated biphenyls and dioxins in Belgium. Effects on the body burden.

The core paper of this debate shows that persistent organic pollutant residues of the 12 chemicals targeted for a phase out under the Stockholm Convention are present in almost all categories of food in the US food supply. For dioxins, the study does not use measured data, but is based upon potential dioxin residues in selected food items. Polychlorinated biphenyls are not included in the study. In this paper we discuss selected data of polychlorinated biphenyl and dioxin concentrations in Belgian food. Some of these exposures are chronic, others are attributable to incidents. Both result in high body burdens in Belgium. The paper also compares the current concentrations in food with the recent standards launched by the EU for dioxins in food, and discusses whether these values adequately protect European citizens.

[Food contamination by emissions from dry cleaning compounds].

Tetrachloroethene (perchloroethylene) from dry-cleaning units may contaminate adjacent flats in the same building. Increased concentrations of tetrachloroethene have been found in foodstuffs in homes situated above dry cleaning units and in foodstuffs from groceries located neat drycleaning units. The concentrations were extremely high in foods rich in fat.

Relationship between the 137Cs whole-body counting results and soil and food contamination in farms near Chernobyl.

We measured the radioactivity in the soil and child food samples from farms near Mogilev (56-270 GBq km(-2) 137Cs), Gomel (36-810 GBq km(-2) 137Cs), and Klincy (59-270 GBq km(-2) 137Cs), who had whole-body 137Cs counting results measured as part of a health examination in the Chernobyl Sasakawa Health and Medical Cooperation Project. Soil contamination on the family farm seems to be the main source of human contamination because most of the people in the area live on small farms and they and their domestic animals eat crops from the farms. A clear correlation was found between the children's whole-body 137Cs counting results and the radioactivity in their food (correlation coefficient: 0.76; confidence level of correlation: 3.2 x 10(-9)). There were also significant correlations between the whole-body 137Cs counting results and both the radioactivity of the soil samples (correlation coefficient: 0.22; confidence level of correlation: 0.0107) and the average contamination level of their current residence (correlation coefficient: 0.20; confidence level of correlation: 0.0174).

Relative hopane content confirming the mineral origin of hydrocarbons contaminating foods and human milk.

Hopanes, triterpenoid hydrocarbons formed under geological conditions, were analysed to confirm the mineral origin of the unresolved complex mixtures of hydrocarbons observed in the gas chromatography with flame ionization detection chromatograms of human milk and certain foodstuffs. The 'relative hopane content' (RHC) is introduced, i.e. it is the area ratio of the sum of the hopanes and the paraffins in the same segment of the chromatogram. The RHC in various mineral oil products (motor oils, hydraulic oils, lubricating oils, Vaseline) was 3.4%, with a relative standard deviation of 19%. The RHC determined in samples of vegetable oils, mussels and clams as well as of human milk containing an unresolved complex mixture of hydrocarbons was in the same range, confirming that these samples were contaminated by mineral oil material.
