Abstract
In de leefomgeving rond het bedrijf Van Voorden
Gieterij BV in Zaltbommel is een immissieonderzoek uitgevoerd. Dit
onderzoek maakt deel uit van een studie naar de blootstelling van omwonenden
aan stoffen, die door de gieterij worden geemitteerd, en naar de
gezondheidsklachten en hinder van omwonenden. Het immissieonderzoek bestond
uit metingen van de concentraties aan schadelijke stoffen in de lucht,
bepaling van de depositie aan stof en metalen en analyses van gras- en
bodemmonsters uit de omgeving van het bedrijf. Uit de resultaten blijkt dat
op werkdagen benedenwinds van het bedrijf verhoogde concentraties aan
schadelijke stoffen in de lucht voorkomen, met piekwaarden tot 10 a 50-maal
het achtergrondniveau. Ook kan er geurhinder optreden, met name in de
winterperiode. De gemiddelde luchtkwaliteit in de omgeving van het bedrijf
ligt op het niveau in regionale en onbelaste stedelijke gebieden, behalve
voor isopropylalcohol en metalen, waarvan de gemiddelde concentraties een
factor 2 tot 5 boven het achtergrondniveau liggen. Ook de depositie aan
metalen in de omgeving van het bedrijf is verhoogd en in grasmonsters uit de
omgeving zijn verhoogde gehalten van enkele metalen gevonden. De
blootstelling van omwonenden door inademing van stoffen in de lucht ligt
onder de gezondheidskundige grenswaarden. De orale blootstelling aan
metalen ligt onder de Toelaatbare Dagelijkse Inname, mits er geen intensieve
consumptie van zelf gekweekte gewassen plaatsvindt ('dagelijks eten uit
eigen tuin'). Intensief consumeren van zelf gekweekte gewassen geeft een
risico op te hoge blootstelling aan lood en barium, met name voor zeer jonge
kinderen.
A study commissioned by the Inspectorate of the Netherlands Ministry of Spatial Planning, Housing and the Environment and the municipality of Zaltbommel was conducted by RIVM on the living environment in the surroundings of the Van Voorden Gieterij BV foundry in the city of Zaltbommel in 2003. The measurements collected were used to study both the exposure of residents to compounds emitted from the foundry and the health effects and annoyance experienced by the residents. This was done through air quality measurements, determination of the particle and heavy-metal deposition, and analyses of grass and soil samples taken in the surroundings of the foundry. The results showed that concentrations of several compounds were enhanced during working hours, with peak values up to 10-50 times above the background level. Annoyance due to bad odours was also thought to occur, particularly in winter. The long-term average rural and urban background concentrations in this area did not, however, exceed the normal levels, except for isopropyl alcohol and heavy metals, for which the average concentrations were 2 to 5 times the normal level. The deposition of heavy metals in the surroundings of the foundry was also found to have increased. Further, elevated levels of some heavy metals, particularly copper, were found in the grass samples. The exposure of residents through inhalation of toxic compounds in the air did not exceed the tolerable limit values. Furthermore, oral exposure to heavy metals was below the Tolerable Daily Intake, provided that residents did not intensively consume produce from their own gardens, i.e. on a daily basis. Daily consumption of self-grown vegetables implies a risk of exposure to lead and barium at levels above the Tolerable Daily Intake, particularly for young children.
