Maintenance of HVAC-systems and components: How to prevent pollution from HVAC-systems?

In the beginning of 1998 a three-year European project, AIRLESS, was started to develop strategies, principles and protocols to improve and control the performance of HVAC-systems and its components for incorporation in codes and guidelines. Twelve institutes, universities and companies, from seven European countries are involved in this project...

Innovative reactive barrier technologies for regional contaminated groundwater

At many industrial sites inadequate waste disposal, leakages and war damages have led to severe groundwater contamination on a regional scale. Standard hydraulic groundwater remediation methods, such as pump-and-treat, in most cases do not lead to satisfactory results, due to the persistence of organic contaminants and the resulting very long...

Matador: final report of task 2

In Task 2 of the MATADOR-project1 measurement methods have been developed for the evaluation of the energy consumption and emissions of vehicles with advanced propulsion systems, such as battery-electric, hybrid-electric and fuel cell vehicles. Based on an inventory of existing and prospective standard test procedures and of technology-specific...

Reduction of campylobacter infections in broiler flocks by application of hygiene measures

Transmission routes of Campylobacter spp. in broilers and possibilities for prevention of infections were studied on two Dutch broiler farms. The occurrence of Campylobacter spp. was studied in successive broiler flocks, in the environment of the farms and in some of the parent flocks involved. Isolates of Campylobacter spp. were typed by using...

Design of a solvent extraction process for PAH-contaminated sediments: The WAU-acetone process

Solvent extraction is one of the possibilities to clean-up polluted sediments. It is especially attractive when the sediment mainly consists of clay particles polluted with contaminants which are not, or not easily, biodegradable. Using acetone as extracting agent the extraction process has been investigated at laboratory scale for treating...

Toxicological profile for o-benzyl-p-chlorophenol

As part of a health-hazard survey on the health risk of hospital cleaning workers from exposure to Lyorthol, a hazard assessment of o-benzo-p-chlorophenol, one of the constituents of Lyorthol, has been prepared. In this paper, the physical and chemical characteristics, kinetics and effects of o-benzochlorophenol are described and discussed, and...

Toxicological profile for o-phenylphenol and its sodium salt

As part of a health-hazard survey on the health risk of hospital cleaning workers from exposure to Lyorthol, a hazard assessment of o-phenylphenol (and its sodium salt), one of the constituents of Lyorthol, has been prepared, In this paper, the physical and chemical characteristics, kinetics and effects of o-phenylphenol and its sodium salt are...

Flitslicht of zwaailicht : hoe opvallend zijn waarschuwingssignalen? [Flashing or rotating lights: how conspicuous are warning signals?]

This article gives an overview of the parameters influencing the conspicuity of warning lights. In general, higher light intensities are more conspicuous. A flashing light is better than a continuous light. Flashing frequencies of about 10 Hz are perceived as unpleasant, and below 1 Hz the light has no warning character. Frequencies between 2...
