Dietary intake of food contaminants in the Netherlands (Dutch Nutrition Surveillance System)

To assess the level of exposure to food contaminants (cadmium, lead, PCBs, DDT, hexachlorobenzene, nitrate and malathion) a total-diet study was carried out. A total of 226 food products were analysed individually; the concentration of contaminants in products not selected for analysis was estimated with the help of published data. The results...

Polycyclic aromatic hydrocarbons in Dutch total diet samples (1984-1986)

Over a period of 2.5 yr, 221 different food items of a 'market basket' of 18-yr-old males were purchased every 3 months. In total, 10 market baskets were collected. The foodstuffs were prepared by normal methods and combined into 23 commodity groups. Homogenates were prepared from each commodity group, followed by analysis for 17 different...

Minerals and trace elements in total diets in The Netherlands

1. During a period of 2.5 years, every 3 months 221 different food items forming a 'market basket' were purchased, prepared and divided into twenty-three food-commodity groups. The 'market basket' was based on a study of the dietary intake of 18-year-old male, Dutch adolescents. In the (homogenized) food groups various minerals and trace...

Pesticides and other chemical residues in Dutch total diet samples (June 1976-July 1978)

Over a period of 2 yr 126 different food items of a market basket of 16-18 yr old males were purchased every 2 months. The foodstuffs were prepared as for eating, and were combined in 12 commodity groups. Twelves samples of each food group were homogenized and analysed for 78 different chemicals, including pesticides, PCBs, bromine, heavy metals...

Food additives and food components in total diets in The Netherlands

During a period of 2 years, every 2 months 126 different food items forming a 'market basket' were purchased, prepared and divided into twelve food commodity groups. The 'market basket' was based on a study of the dietary pattern of 16- to 18-year-old male adolescents. In the (homogenized) food group various additives and components of...

Improved determination of dalapon residues in plant tissues and natural water by derivatization and electron capture gas chromatography

Survey of the contamination of Dutch coastal water by chlorinated hydrocarbons, including the occurrence of methylthio-pentachlorobenzene and di-(methylthio)tetrachlorobenzene

In 1976 contamination of Dutch coastal waters by organochlorine compounds was assessed by analysing mussels, Mytilus edulis, as an indicator-organism. HCB, dieldrin, endrin, p,p'-DDT, p,p'-TDE and PCB's were detected, and also two new compounds previously unknown in the aquatic fauna. Using gas-liquid chromatography, mass spectrometry and 13C...

Residues of pentachloronitrobenzene and related compounds in greenhouse soils

Pentachloronitrobenzene (PCNB, also known as Quintozene, Terraclor) is used as a soil fungicide in greenhouses, mainly for the control of Rhizoctonia and Botrytis in lettuce. During an examination (by gas liquid chromatography) of a number of soil samples from greenhouses, not only a PCNB peak was found in the chromatograms, but also several...

Identification and toxicological evaluation of chlorinated dibenzofuran and chlorinated naphthalene in two commercial polychlorinated biphenyls

In a previous study (Vos & Koeman, Toxic. appl. Pharmac. 1970. In press) a significant difference in toxicity was found between three commercial polychlorinated biphenyl (PCB) preparations, high mortality, liver necrosis and chick oedema-like lesions being associated with only two of the compounds tested. In the present study, column and gas...

Chlorinated biphenyls in fish, mussels and birds from the river rhine and the netherlands coastal area

Polychlorinated biphenyls are widely used in industry, and they are now making an appearance in the world's wildlife. Besides being a hazard in their own right, they interfere with the detection of organochlorine insecticides such as DDT. © 1969 Nature Publishing Group. Chemicals/CAS: liver extract, 72980-85-9; tissue extract, 1390-94-9, 8001-49...
