A critical review finds government agencies allow, permit, license, or ignore arsenic releases to surface soils. Release rates are controlled or evaluated using risk-based soil contaminant numerical limits employing standardized risk algorithms, chemicalspecific and default input values. United States arsenic residential soil limits, 0.4–40 ppm, generally correspond to a one-in-one-million to a one-in-ten-thousand incremental cancer risk range viaingestion of or direct contact with contaminated… Expand
Natural Background and Anthropogenic Arsenic Enrichment in Florida Soils, Surface Water, and Groundwater: A Review with a Discussion on Public Health Risk
Exposure to arsenic in soils at concentrations that exceed the Florida default cleanup level set specifically for residential environments does not necessarily pose a meaningful a priori public health risk, given important considerations. Expand
Collateral benefits and hidden hazards of soil arsenic during abatement assessment of residential lead hazards.
This study recommends that soil samples collected under HUD programs should be collected from areas of lead and arsenic deposition and tested for arsenic as well as lead, and that soil abatement decisions consider soil-arsenic aswell as soil-lead guidelines. Expand
Soil heavy metal contamination in residential neighborhoods in post-industrial cities and its potential human exposure risk
This study assessed the extent of potential human risk to heavy metal exposure by comparing concentrations of arsenic (As), cadmium (Cd), chromium (Cr), lead (Pb) and zinc (Zn) in soil in 43 vacantExpand
Unsaturated zone arsenic distribution and implications for groundwater contamination.
GIS analyses showed poor correlations between groundwater arsenic and percent cultivated land, further supporting the idea that anthropogenic-derived arsenic in the shallow subsurface is not linked to groundwater arsenic contamination in this region. Expand
Home gardening near a mining site in an arsenic-endemic region of Arizona: assessing arsenic exposure dose and risk via ingestion of home garden vegetables, soils, and water.
The human-health risk posed by gardening near a legacy mine and smelter in an arsenic-endemic region of Arizona was characterized and the importance of site-specific risk assessment, and the need for species-specific planting guidelines for communities is highlighted. Expand
Distribution and Abundance of Arsenic in the Soils and Sediments of O‘ahu, Hawai‘i
AbstractLack of high-spatial-resolution soil and sediment arsenic data for Hawai‘i has generated substantial disagreement between researchers and regulators regarding the magnitude of natural levelsExpand
Are Soil Pollution Risks Established by Governments the Same as Actual Risks
Though soil pollution policies in North America and the European Union increasingly use risk-based standards, the construction and application of such standards are often deficient in taking accountExpand
Effects of soil types and forms of arsenical pesticide on rice growth and development
For decades, repeated and widespread use of arsenical pesticides has significantly contributed to arsenic contamination in soils. Residues from the overuse of these arsenicals may result inExpand
Effect of soil aging on arsenic fractionation and bioaccessibility in inorganic arsenical pesticide contaminated soils.
Abstract Ingestion of As – contaminated soil by children is a growing concern in former agricultural lands converted to residential or recreational land use areas. The mobility and bioavailability ofExpand
Strategies for soil management
Abstract This chapter is completely devoted to explaining contaminated soil management plans for the handling and disposal of contaminated soils that are anticipated to be encountered during futureExpand


Impacts of Historic Arsenical Pesticide Use on Residential Soils in Denver, Colorado
A variety of arsenical compounds were used as pesticides in the U.S. during the first half of the 20th century. Until recently, the impacts of these practices were thought to be limited to orchardExpand
Health risk assessment for arsenic contaminated soil
This paper describes risk assessment methods for two chronic exposure pathways involving arsenic contaminated soil, namely inhalation of fugitive dust emissions over a lifetime, and inadvertent soil/house dust ingestion, using cancer potency factors developed by the U.S. Environmental Protection Agency.

Determination of Background Concentrations of Inorganics in Soils and Sediments at Hazardous Waste Sites
Hazardous waste sites may pose a threat to human health and the environment when toxic substances are released. However, the contaminants present at a waste site may have originated ‘on-site’ (i.e.,Expand
Concentrations of arsenic have been measured in soils, streambed sediments, ground water, surface water, and drinking water in New Jersey over the past few decades as part of several U.S. GeologicalExpand
Occurrence and distribution of arsenic in soils and plants
The effect of past applications on arsenic accumulation in soil, phytotoxicity to and uptake by plants as influenced by soil properties, and alleviation of the deleterious effects of arsenic are focused on. Expand
Issues in setting health-based cleanup levels for arsenic in soil.
Risks from arsenic in soil are lower than what would be calculated using default toxicity values for arsenic in drinking water because of differences in chemical form, bioavailability, and excretion kinetics. Expand
Environmental Sampling and Analysis of Coal Fly Ash Intended for Use in Roads
Government and private organizations around the world are currently encouraged to recycle wastes that were formerly placed in toxic waste landfills based on concerns for human and environmentalExpand
An analysis of soil arsenic records of decision.
The risk assessment process is important in defining cleanup goals; however routine use of site-specific variables is necessary to ensure an accurate assessment of potential site risks and to preclude over-remediation that may result from the use of default risk variables. Expand
Site-specific data confirm arsenic exposure predicted by the U.S. Environmental Protection Agency.
The EPA uses an exposure assessment model to estimate daily intake to chemicals of potential concern. At the Anaconda Superfund site in Montana, the EPA exposure assessment model was used to predictExpand
Estimating Total Arsenic Exposure in the United States
Publisher Summary Arsenic (As) is a component of the earth's crust and is ubiquitous in the environment. Consequently, humans are exposed to As from a variety of sources, such as food, water, air,Expand
