In Nova Scotia, taking out the trash may now be easier because there's less to take out--in fact, 50% less. The eastern province has become the first in Canada to reduce solid waste disposal by 50% over 1989 levels, a nationwide goal set that year...
Allium vegetables have been shown to have beneficial effects against several diseases, including cancer. Garlic, onions, leeks, and chives have been reported to protect against stomach and colorectal cancers, although evidence for a protective effect...
Brominated flame retardants are a novel group of global environmental contaminants. Within this group the polybrominated diphenyl ethers (PBDE) constitute one class of many that are found in electrical appliances, building materials, and textiles....

Most anyone would agree that one of the most important aspects of people's love affairs with their automobiles is the color of the vehicle. Whether vibrant red, stately gray, or stealthy black, the color of a car says something about its driver (or...
Adverse health effects of airborne toxicants, especially small respirable particles and their associated adsorbed chemicals, are of growing concern to health professionals, governmental agencies, and the general public. Areas rich in petrochemical...
In their recent commentary, "Children's Health, Susceptibility, and Regulatory Approaches to Reducing Risk from Chemical Carcinogens," Charnley and Putzrath (1) noted the seminal importance of the National Academy of Sciences (NAS) report Pesticides...
The objectives of this study were to to identify maternal characteristics associated with traditional food consumption and to examine food items associated with polychlorinated biphenyls (PCBs) and mercury body burden in pregnant Inuit women from Northern...
The widely used organophosphate pesticide chlorpyrifos is a suspected neuroteratogen. In the current study, we compared the effects of chlorpyrifos and its major metabolites in two in vitro models, neuronotypic PC12 cells and gliotypic C6 cells. Chlorpyrifos...
The acute toxicity of diethylnitrosamine (DEN) to the liver has been well documented in the literature, but whether DEN also affects the endocrine parameters has been addressed in only a few studies. We thus investigated the effects of DEN on pituitary,...
At times it pays to live in the first lane. Drivers motoring in freeway carpool lanes not only avoid the congestion of traffic in slower neighboring lanes, they may also avoid lung congestion from pollutants that seep into their vehicles as they creep...
If you really want to impress your green friends, what better way than by driving a car that's made partially of grass? The car looks and feels like any other until it's composted in a landfill. Then, over time, microbes snack on remnants of the aging...
We used structure--activity relationship modeling to estimate the number of toxic chemicals among the high-production volume (HPV) group. We selected 200 chemicals from among the HPV chemical list and predicted the potential of each for its ability...
Technologies for Closing DNA Sequence Gaps and Improving Methods for Obtaining the Sequence of Difficult-to-Sequence Regions The National Human Genome Research Institute (NHGRI) invites applications to develop strategies and technologies for obtaining...
Polybrominated diphenyl ethers (PBDEs), widely used as flame retardants, are emerging contaminants of concern. A 1998 study of Swedish women showed that PBDE concentrations in mothers' milk increased exponentially from 1972 to 1997, doubling every...
We evaluated the airway irritation of isoprene, isoprene/ozone, and isoprene/ozone/nitrogen dioxide mixtures using a mouse bioassay, from which we calculated sensory irritation, bronchial constriction, and pulmonary irritation. We observed significant...
The aim of this study was to determine whether total copper or soluble copper concentration is associated with gastrointestinal signs and symptoms. Forty-five healthy adult women (18-55 years of age), living in Santiago, Chile, ingested tap water with...
We appreciate the comments of Landrigan et al. and find that few of them are inconsistent with the conclusions presented in our paper (1). Indeed, many of their comments are mentioned in our paper. Nowhere in our paper, however, do we argue that child-protective...
1,3-Butadiene (BD), a suspected human carcinogen, is used as the raw material in industries to make synthetic butyl rubber and plastics. Simulation models using experimental animal data have shown that physiologic factors play an important role in...
A previously healthy woman developed hypersensitivity pneumonitis of such severity that she required chronic systemic corticosteroid therapy for symptom control. Detailed investigation of her workplace and home environments revealed fungi in her typical...
The association of malignant mesothelioma (MM) and nonoccupational asbestos exposure is currently debated. Our study investigates environmental and domestic asbestos exposure in the city where the largest Italian asbestos cement (AC) factory was located....
In 1997 the group now known as Environmental Defense (ED) published Toxic Ignorance, a report focused on the dearth of basic toxicologic information on high production volume (HPV) chemicals. These chemicals, which are used in various industries and...
Power sanding exterior paint is a common practice during repainting of old houses in New Orleans, Louisiana, that triggers lead poisoning and releases more than Pb. In this study we quantified the Pb, zinc, cadmium, manganese, nickel, copper, cobalt,...

Of the sewage sludge--or postprocessing sewage biosolids--produced annually in the United States, over half is applied to land. Sludges are treated to reduce odors and pathogens and their metal contents are regulated, but content of persistent organic...
The NIEHS announced on 3 May 2001 that five research centers comprising the Comparative Mouse Genomics Centers Consortium have been selected to develop mouse lines with genetic variations that may be key to understanding the effects of environmental...
The NIEHS Division of Extramural Research and Training (DERT), in collaboration with the National Toxicology Program (NTP), initiated a unique grants program in 1997 that funds investigator-initiated research to provide data to aid in defining the...
Microarray technology has been applied to a variety of different fields to address fundamental research questions. The use of microarrays, or DNA chips, to study the gene expression profiles of biologic samples began in 1995. Since that time, the fundamental...
After almost three decades, 109 volumes, hundreds of thousands of pages, and immeasurable hours of editing and review, EHP is saying goodbye to it's editor-in-chief, Gary Hook. Hook is retiring from the National Institute of Environmental Health Sciences...
We examined human adipose tissue, liver, and bile from humans in Japan to understand the contamination status, specific accumulation, and elimination of two newly identified environmental contaminants, tris(4-chlorophenyl)methane (TCPMe), tris(4-chlorophenyl)methanol...
As U.S. manufacturers and retailers rush to tap into the multibillion-dollar-per-year "green merchandise" market, labels on items ranging from eggs to diapers tout an ever-expanding number of qualifiers such as nontoxic, all natural, and organic to...
Individuals with a common genetic variation may not metabolize certain drugs as readily as those without the mutation, researchers report in the April 2001 Nature Genetics. As a result, they may be particularly sensitive to these medications. This...
Endocrine-disrupting chemicals are among the most complex environmental health threats known today. By mimicking natural hormones such as estrogen and testosterone, these chemicals can interact with the body's endocrine system and exert toxic effects...
Environmental scientists play a key role in society's responses to environmental problems, and many of the studies they perform are intended ultimately to affect policy. The precautionary principle, proposed as a new guideline in environmental decision...
Radioprotection norms have been based on risk models that have evolved over time. These models show relationships between exposure and observed effects. There is a high level of uncertainty regarding lower doses. Recommendations have been based on...
Maintenance of old homes can be an extremely hazardous activity if improperly done. For example, lead poisoning can arise from exposure to lead-based paint chips as well as dust produced during prep work for repainting. In this issue, researchers led...
