van der Grift, B. (author), Griffioen, J. (author), TNO Bouw en Ondergrond (author)Historic emissions from ore smelters typically cause regional soil contamination. We developed a modelling approach to assess the impact of such contamination on groundwater and surface water load, coupling unsaturated zone leaching modelling with 3D groundwater transport modelling. Both historic and predictive modelling were performed, using a...article 2008

Artola-Garicano, E. (author), Borkent, I. (author), Hermens, J.L.M. (author), Vaes, W.H.J. (author)In the current study, the removal of slowly degradable hydrophobic chemicals in sewage treatment plants (STPs) has been evaluated with emphasis on the combination of free and total concentration data. Free and total concentrations of two polycyclic musks were determined in each compartment of four STPs. The free concentration of the polycyclic...article 2003

(author), Instituut CIVO-Toxicologie en Voeding TNO (author)In the long-term cooperative project Voluntary Plan of Action (1990) between the Dutch Soap and Detergent Association (NVZ) and the Dutch Ministry of Housing, Spatial Planning and the Environment (VROM) environmental risk assessments of several main components of laundry cleaning formulations were completed. As a part of that project the...article 2002

Miedema, H.M.E. (author), Walpot, J.I. (author), Vos, H. (author), Steunenberg, C.F. (author)Existing data from field surveys have been reanalysed in order to establish relationships between odour annoyance and odour exposure concentrations caused by (bio) industrial odours in a community. The percentage of highly annoyed persons (%HA) was found to have a simple relationship with the logarithm of the 98 percentile of the odour exposure...article 2000

(author), van Soolingen, D. (author), van Loveren, H. (author), Centraal Instituut voor Voedingsonderzoek TNO (author)In this study the effects of inhalatory exposure to coal fly ash on lung pathology and the immune system in rats were examined. Rats were exposed to 0, 10, 30, or 100 mg/m3 coal fly ash (6 h/day, 5 days/wk) for 4 wk, or to 0 and 100 mg/m3 for 1 wk, and for 1 wk followed by a recovery in clean air of 3 wk. A concentration-related increase in lung...article 1999

Alkemade, M.M.C. (author), Koene, J.I.A. (author), TNO Milieu, Energie en Procesinnovatie (author)An immobilization process is described which is based on sulphur (instead of cement) as a binding agent for the treatment of hazardous waste materials. Elemental sulphur is able to bind chemically metals such as mercury and, to a lesser extent, lead as metal sulphides. Furthermore, sulphur forms a compact solid mass that has a low permeability,...article 1996
