De risico's van milieugevaarlijke stoffen in importcontainers : De stand van zaken 2007

Abstract

People in the immediate surroundings of a maritime container that has been opened recently may be exposed to high concentrations of volatile organic substances. Exposure to such substances may result in an acute health risk. These substances may come into contact with consumers if they evaporate from products that were transported in those containers. RIVM has examined three such products: two mattresses and a pair of shoes. These products were selected because the consumer, when using these products, is exposed to these substances for a long time. Despite this prolonged duration, no unacceptable health risks were found. RIVM cannot rule out health risks in all situations. However, it is not possible to quantify these risks: the relevant data are lacking and there are many exposure pathways. The hazardous substances get into containers and products in two ways. Substances such as methyl bromide and 1,2-dichloroethane are used to disinfect products and packaging timber, and are put into the container before transport. During prolonged transport they may enter the relevant goods. Other substances, e.g. benzene en toluene, are used as components or solvents in the production process. If such substances are contained in the products, they may evaporate from the products in enclosed areas. RIVM sees various options for reducing exposure to these substances. One option is to reduce their use. Producers and importers may achieve this by placing additional requirements on the use of such substances in the production process or during transport.
