Human biomonitoring (HBM) is widely recognised as a useful tool to aid assessment of exposure to chemical substances, but our ability to detect hazardous substances (or their metabolites and health effects) often exceeds our understanding of their biological relevance. There are only a few established frameworks for developing and using occupational and environmental biological guidance values ...

This article investigates whether the choice experiment approach can be used to assess people's preferences and the determinants of these preferences in order to estimate the costs and benefits of different configurations of the transport of hazardous materials by rail. Changes in the exposure to hazardous materials that people are subjected to are used rather than changes in accident risk. To ...

Reproductive function has been shown to be sensitive to changes in the physical, psychosocial and chemical environments. Although reproductive effects of occupational exposure to hazardous chemicals have been well documented in the literature, the potential effects of chemical contaminants at levels representative of contemporary exposures in the general population are much less certain. Eviden...

Organic matter from profundal lake sediments was fractionated and analyzed with high depth resolution, and the size-class distribution of humic substances was determined by gel-permeation chromatography. Together with a depthdependent increase of the thermal stability of the organic matter and an increasing C/N atomic ratio of the humic acids, the size-distribution patterns of di€erent fraction...

The purpose of this study was to systematically investigate hazardous materials (hazmat) releases and determine the mechanisms of these accidents, and the industries/activities and chemicals involved. We analyzed responses by Massachusetts' six district hazmat teams from their inception through May 1996. Information from incident reports was extracted onto standard coding sheets. The majority o...

We evaluated 10 years of reported hazardous cargo incident information from the U.S. Air Force and Naval Safety Centers. In this first of two papers describing the hazardous cargo problems reported by the two services, we describe types of aircraft and types of hazardous cargo involved in incidents not causing aircraft mishaps. Normally, hazardous cargo must be manifested as such and no passeng...

The Pseudomonas sp. PAMC 26793 was isolated because of its high ability to degrade humic acids from a subarctic grassland in Alaska. We sequenced the PAMC 26793 genome to discover the genes for degradation of natural humic substances and to provide further information for the degradation process of soil bacteria in a low-temperature environment.

The events of 11 September 2001 became the catalyst for many to shift their disaster preparedness efforts towards mass-casualty incidents. Emergency responders, healthcare workers, emergency managers, and public health officials worldwide are being tasked to improve their readiness by acquiring equipment, providing training and implementing policy, especially in the area of mass-casualty decont...
