Book excerpt: The U.S. Environmental Protection Agency (USEPA), in a collaborative effort with other Federal agencies, states, and private industry, is developing Ecological Soil Screening Levels (Eco-SSLs) for ecological risk assessment of contaminants at Superfund sites. Earthworm (Eisenia fetida) cocoon production and survival tests were conducted in a Sassafras sandy loam soil that supports relatively high bioavailability of barium (Ba), beryllium (Be), manganese (Mn), and antimony (Sb). For the metals tested, cocoon production was a more sensitive endpoint than was survival. Bounded Lowest Observed Effect Concentrations (LOECs) (mg kg-1) for cocoon production, as determined by analysis of variance (ANOVA), were 83, 86, 433, and 1236 for Be, Sb, Ba, and Mn, as compared to LOECs for survival of 110, 697, 1585, and 2222, respectively. Bounded No Observed Effect Concentrations (NOECs) (mg kg-1) for cocoon production, as determined by ANOVA, were 57, 60,258, and 1111 for Be, Sb, Ba, and Mn, as compared to NOECs for survival of 83, 617,1348, and 1444, respectively. Non-linear regression analysis of cocoon production data showed that the relative toxicity (EC20 mg kg-1) of the four metals was in the order of Sb (30) = Be (52)> Ba (370)> Mn (629). These results will be submitted to the Eco-SSL Work ou for review and inclusion in their database.

Book excerpt: The U.S. Environmental Protection Agency is developing Ecological Soil Screening Level (Eco-SSL) benchmarks for ecological risk assessment of contaminants at Superfund sites. Benchmarks for invertebrates were developed from existing literature. Insufficient information for barium (Ba), beryllium (Be), manganese (Mn), and antimony (Sb) to generate Eco-SSLs necessitated standardized toxicity testing to fill the data gaps. We used the Folsomia Folsomia candida (F. candida) Reproduction Test in this study. This test was selected on the basis of its ability to measure chemical toxicity to ecologically relevant test species during chronic assay, and its inclusion of at least one reproductive component among the measurement endpoints. Tests were conducted in Sassafras sandy loam soil, which supports relatively high bioavailability of metals. Weathering/aging procedures for spiked treatment soil were incorporated into the study to better reflect the "real world" exposure conditions.

Benchmarks for invertebrates Were developed from existing literature. Insufficient information for Ba, Be, Mn, and Sb to generate Eco-SSLs necessitated standardized toxicity testing to fill the data gaps.

This test was selected on the bases of its ability to measure chemical toxicity to ecologically relevant test species during chronic assay, and its inclusion of at least one reproductive component among the measurement endpoints. Tests were conducted in Sassafras sandy loam soil, which supports relatively high bioavailability of metals. Aging/weathering procedures for amended treatment soil were incorporated into the study to better reflect the "real world" exposure conditions. The toxicity order based on juvenile production was Be> Mn> Sb> Ba with EC20 values of 45, 116, 194, and 585 mg kg-1, respectively. These results show that ERT is a robust and sensitive assay for toxicity assessments and is appropriate for the Eco-SSL development.

This book was released on 2003-05-03 with total page 433 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bioavailability refers to the extent to which humans and ecological receptors are exposed to contaminants in soil or sediment. The concept of bioavailability has recently piqued the interest of the hazardous waste industry as an important consideration in deciding how much waste to clean up. The rationale is that if contaminants in soil and sediment are not bioavailable, then more contaminant mass can be left in place without creating additional risk. A new NRC report notes that the potential for the consideration of bioavailability to influence decision-making is greatest where certain chemical, environmental, and regulatory factors align. The current use of bioavailability in risk assessment and hazardous waste cleanup regulations is demystified, and acceptable tools and models for bioavailability assessment are discussed and ranked according to seven criteria. Finally, the intimate link between bioavailability and bioremediation is explored. The report concludes with suggestions for moving bioavailability forward in the regulatory arena for both soil and sediment cleanup.

Available in PDF, EPUB and Kindle. Book excerpt: Mammalian Toxicology surveys chemical agents and examines how such chemicals impact on human health, emphasizing the importance in minimizing environmental exposure to chemical and physical hazards in our homes, communities and workplaces through such media as contaminated water, soil and air. Starting with the basic principles on a wide range of toxic agents, this textbook describes how they enter the body, their mechanisms of action once inside, and strategies for diagnosis, prevention and treatment. Topics covered include: General principles of toxicology: pharmacological and toxicological principles underpinning the study of toxicology, risk assessments and mechanisms of cell death Disposition: routes of chemical exposures, entry into the body and various tissues, storage, metabolic biotransformation and elimination, with examples from various toxicants. Toxic agents: the occurrences, disposition in the body, health effects, toxic mechanisms, antidotes and treatments of a range of agents including pesticides, metals, solvents, gases, nanomaterials, food components and additives, pharmaceuticals, drugs of abuse, natural toxins, endocrine disruptors, radiation, and warfare weapons. Toxic effects: including neurotoxicity, developmental toxicity, immunotoxicity, teratogenecity, male and female reproductive toxicity, mutagenecity, carcinogenicity, pulmonary toxicity, cardiovascular toxicity, hepatotoxicity, gastrointestinal toxicity and cardiovascular toxicity Toxicology and society: epidemiological studies of chemical-induced diseases in human populations, and a vision for toxicology in the 21st century. Mammalian Toxicology is an essential primer for students of toxicology, biochemistry, biology, medicine and chemistry. It is also appropriate for professional toxicologists in research or regulatory affairs, and anyone who needs to understand the adverse effects of toxic agents on the human body.
