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...

The relative concentrations of hydrocarbons in the atmosphere may provide information concerning their origin. It appears that the hydrocarbon composition measured in Delft (The Netherlands) is entirely different for northern and southern wind directions. This points to different sources. The most important sources for this area are natural gas...

Using the microthread technique the survival of Escherichia coli MRE 162 in open air was measured in different parts of The Netherlands. The presence of bactericidal compounds (open air factor=OAF) could be demonstrated on several days and quantitated in relative units of OAF concentration. In the absence of ozone the OAF concentration was...

If the trend in risk of tuberculosis infection is estimated from the 1967-1976 data alone (which contain only 6 usable annual figures), the estimate is a decrease of 9.3% annually, a figure substantially lower than the estimate from the 1956-1966 data alone, viz. 13.7%. It is as yet impossible to decide whether or not this represents a real...

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...

Starting in the winter 1964-1965, the TNO Research Institute for Environmental Hygiene has determined the PAH-concentrations of the atmosphere at several locations in The Netherlands. Long series of data are available for several stations. The trend in the concentrations is spectacular: the concentrations have fallen from relatively high values...

Studies on microwave surface scattering in The Netherlands have indicated the need of accurate radar systems for applications in remote sensing. A SLAR system with digital recording was developed and is now being used for several programs. This system was designed with special attention for speckle reduction and system accuracy. The digital data...

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...

Short-term tests designed to detect possible carcinogenicity have been extensively refined during the last years. Presently, many more or less simple and convenient systems are available to detect mutations, chromosome effects, DNA damage, and malignant transformation. Although their relevance to carcinogenicity is often reasonably good,...

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...

The incidence of childhood diabetes (0-19 years of age) in The Netherlands, where there is no nationalized health-care system, was investigated retrospectively in the years 1978 to 1980 inclusive. The method chosen was a questionnaire among all Dutch paediatricians and internal physicians acting as consultants. Ascertainment was by the same...

In this paper concentration levels of various classes of organic chemicals in The Netherlands are reported for the base year 1980. From these levels the average intake of the Dutch population by inhalation was calculated to be ~1.5 g year-1. This gives reason for concern because many of the compounds either seem to exhibit carcinogenic...

The vitamin B6 status of women suffering from premenstrual symptoms (PMS, n = 19) and a group of matched controls (n = 19) has been investigated. The women volunteering in the study were selected on strictly defined criteria. Several biochemical parameters of the metabolism of vitamin B6 and tryptophan were studied in blood and urine samples...

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...

In a case-control study in The Netherlands, we observed a significantly lower consumption of fermented milk products (predominantly yogurt and buttermilk) among 133 incident breast cancer cases as compared to 289 population controls (mean ± SD among users only, 116 ± 100 versus 157 ± 144 g/day; P<0.01). The age-adjusted odds ratio of daily...

In four types of newly built single family dwellings and in apartments of a block of flats in the Netherlands, the behaviour and motivations of the occupants are studied with respect to their response to heating and ventilation, as well as their judgment on indoor air and climate variables such as tobacco smoke, cooking smells, vapour, mould,...

Limited resources for health care and increasing health care costs have led to proposals to expand home care services. Presently, home care technology is rather primitive. Its development and use have been largely unplanned. Nonetheless, home care technology is growing in response to obvious needs, and a number of experiments in the Netherlands...

Two hundred and three patients with venous thrombophilia were investigated in order to find out whether an elevated plasma concentration of plasminogen activator inhibitor (PAI) could be a cause of their tendency to thrombosis. The patients were studied in an asymptomatic period about 3 months after their last thromboembolic episode. PAI...
