The Agency for Toxic Substances and Disease Registry (ATSDR) uses chemical-specific minimal risk levels (MRLs) to assist in evaluating public health risks associated with exposure to hazardous substances. MRLs are estimates of daily human exposure to a chemical that are likely to be without an appreciable risk of adverse noncancer health effects over a specified duration of exposure. MRLs serve...

The recent US Commodity Flow Survey data suggest that transporting hazardous materials (HAZMAT) often involves multiple modes, especially for long-distance transportation. However, not much research has been conducted on HAZMAT location and routing on a multimodal transportation network. Most existing HAZMAT location and routing studies focus exclusively on single mode (either highways or railw...

Environmentalists worry that hazardous wastes produced in industrialized nations are being dumped in cash-starved developing countries--the countries with the least political or economic clout to resist and the fewest resources for managing these toxic imports. Imported waste can pose a serious threat to the health of human populations and ecosystems if not managed appropriately. In 1989, the i...

The number of railroad events reported to the Agency for Toxic Substances and Disease Registry's Hazardous Substances Emergency Events Surveillance system increased from 84 in 1993 to 177 in 1998. Comparisons of data on railroad and non-railroad events were made. The results overall indicated a greater potential impact of railroad events on public health. A median number of 2039 persons were li...

The furniture industry is one of the most dynamically developing sectors Polish economy. Unfortunately, due to national law, it involves producing a significant amount wood-based waste, which can only be incinerated in installations that meet requirements for waste incineration or co-incineration plants. This presence various types chemical additives post-production residues, increases emission...

Wildfire occurrence frequency is increasing worldwide, generating more and concern, especially in Wildland-Urban interfaces (WUI) Wildland-Industrial Interfaces (WII) areas. Wildfires approaching WII can cause severe damage to people industrial assets. In these scenarios, storage tanks present installations are among the most vulnerable pieces of equipment, since they usually located proximity ...

I. Review information and studies on the environmental exposure and effects of nanoparticulate silver; II. Comment on known or predicted environmental exposure levels and whether these present a human health or environmental risk; III. Comment on the nature of appropriate measures to minimise risks, if these are felt to be necessary at this point in time; IV. Consider what action should be take...

Footwear is a complex product, comprising various materials which are made using a wide range of chemicals. Some of these chemicals are hazardous for health and for the environment. Converting raw hides into finished products requires a number of complex treatments, for which large amounts of chemicals and water are used. The purpose of this study is to provide information on the harmful substa...
