Jongen, M.J.M. (author), Ravensberg, J.C. (author), Engel, R. (author), Leenheers, L.H. (author), Medisch Biologisch Laboratorium TNO (author)Health hazard surveys have been conducted on Dutch bulb farms and in greenhouses used for cultivation of carnations in order to determine occupational exposure to the fungicides zineb and maneb. Occupational exposure is estimated by determining inhalatory and dermal exposure. Inhalatory exposure is measured by personal air sampling and dermal...article 1991

Jongen, M.J.M. (author), Engel, R. (author), Leenheers, L.H. (author), Medisch Biologisch Laboratorium TNO (author)As part of a survey of occupational exposure to pesticides in greenhouses for growing ornamentals, analytical methods were developed and validated for the measurement of exposure of workers to the pesticide abamectin. Abamectin consists of a mixture of avermectin-B1a and avermectin-B1b, which are members of a class of fermentation products of...article 1991

Miedema, H.M.E. (author), Ham, J.M. (author)Odour exposures were determined by odour emission measurements and dispersion calculations. Odour annoyance was determined by a social survey. The relation between the odour concentration that is exceeded during 2 per cent of the year preceding the interviews, and the percentage 'annoyed' plus 'very annoyed' is presented.article 1988

Medisch Biologisch Laboratorium TNO (author), Muijser, H. (author), Hoogendijk, E.M.G. (author), Hooisma, J. (author), Twisk, D.A.M. (author)In a group of workers exposed to high levels of lead during five months nerve conduction velocity parameters were evaluated at the termination of exposure, and also three and fifteen months later. At the termination of exposure the mean blood lead level was 4.0 ??mol/l, and motor conduction velocities in the median and the ulnar nerves were...article 1987

Guicherit, R. (author), Schulting, F.L. (author), Instituut voor Milieuhygiëne en Gezondheidstechniek TNO (author)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...article 1985

(author), Hoofdgroep Maatschappelijke Technologie Centraal Laboratorium TNO (author)FIy ash from fluidised bed combustion of bituminous coals contains carbonaceous cenospheres of several forms including thick-walled opaque, transparent with a skeletal structure and 'balloons' without skeletons. The influence on cenosphere formation of particle size, temperature, heating rate, petrographic composition, etc. is reviewed. The...article 1984

Lindqvist, F. (author), Instituut voor Milieuhygiëne en Gezondheidstechniek TNO (author)A continuous method for the measurement of SO2 in ambient air at trace levels is described. The principle of detection is based on the anodic oxidation of SO2 in a galvanic cell. A differential measuring technique with a cell with two anodes and one cathode is used; background and noise current are low and stable. A feature of the measuring...article 1978

Kruysse, A. (author), Feron, V.J. (author), Immel, H.R. (author), Centraal instituut voor voedingsonderzoek TNO (author)The inhalation toxicity of peroxyacetyl nitrate (PAN) was examined in acute (single exposure), subacute (4-wk repeated exposure) and subchronic (13-wk repeated exposure) studies in rats. The 4-hr LC50 was found to be 95 ppm. In the 4-wk study rats were exposed to 0, 0.9, 4.1 or 11.8 ppm PAN vapor for 6 hr/day, 5 days/wk. Exposure to 11.8 ppm...article 1977

Bos, R. (author), Guicherit, R. (author), Hoogeveen, A. (author), Instituut voor Milieuhygiëne en Gezondheidstechniek TNO (author)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...article 1977

de Mik, G. (author), de Groot, I. (author), Medisch Biologisch Laboratorium TNO (author)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...article 1977
