WASHINGTON, DC (December 7, 2017) — This week, Congresswomen Rosa DeLauro (CT-03) introduced legislation to limit the amount of inorganic arsenic that is permitted in rice and rice-based products. The Reducing food-based Inorganic Compounds Exposure (RICE) Act would require the Food and Drug Administration (FDA) to set a maximum permissible level of inorganic arsenic for rice and …
This assessment found that the cancer potency of inorganic arsenic was much higher than previously thought, in large part due to new cancers confirmed to be associated with inorganic arsenic exposure.
The Food and Drug Administration on Friday proposed new limits for inorganic arsenic in infant rice cereal, an effort to reduce the leading source of arsenic exposure for babies.
Arsenic and Inorganic Arsenic Compounds Page 2 2 3 et al. 1987). The strongest evidence that arsenic is responsible for the observed lung 4 cancer comes from quantitative dose-response data relating specific arsenic exposure 5 levels to lung cancer risk. These data are available for arsenic-exposed workers at the
Facts about arsenic Arsenic is a naturally occurring substance. ... For example, inorganic arsenic - arsenic combined with oxygen, chlorine or sulfur - is thought to be the most toxic, while most organic forms of arsenic are relatively less toxic. ... Natural background levels of arsenic in Washington.

Investigation of Background Inorganic and Organic Arsenic in Four Washington Lakes Abstract During the summer and fall of 2002, arsenic data were collected from four lakes of varying geology, climate, and altitude: Black Lake (Stevens County), Conner's Lake (Okanogan County), Mountain Lake (San Juan County), and Lake Pleasant (Clallam County).
Organic arsenic is less harmful than inorganic arsenic. Seafood is a common source of the less toxic organic arsenic in the form of arsenobetaine. The arsenic reported in 2012 in fruit juice and rice by Consumer Reports was primarily inorganic arsenic.
Arsenic is an element that is a natural part of Earth's crust. It exists in organic and inorganic forms, but the U.S. Environmental Protection Agency (EPA) regulations focus on inorganic arsenic because it is more prevalent in drinking water. Traditionally, many critics have contended that inorganic arsenic …
Washington State Regulatory Authority; ... Levels of arsenic in Washington's soil and water are generally too low to cause health effects from short-term exposure. ... The most common test measures the total amount of arsenic and does not distinguish between the toxic "inorganic" forms of arsenic that are a health concern and the less toxic ...
It is not unusual that the inorganic arsenic would be slightly elevated from the dietary arsenic alone. The individual with a total arsenic level of 94 μg/L and an inorganic arsenic level of 15 μg/L probably represents the most exposed individual in this exposure investigation.
Inorganic arsenic and its compounds, upon entering the food chain, are progressively metabolized through a process of methylation. For example, the mold Scopulariopsis brevicaulis produces significant amounts of trimethylarsine if inorganic arsenic is present.
Washington, DC 20003 Dear Mr. Dingess: Thank you for your January 3, 2008, letter to the Occupational Safety and Health Administration's (OSHA's) Directorate of Enforcement Programs (DEP). In your letter you requested clarification of OSHA's Inorganic Arsenic Standard 29 CFR 1010.1018.
Citing OEHHA's determination that consuming 10 micrograms of inorganic arsenic per day (except through inhalation) poses "no significant risk" of cancer, the Plaintiffs argued that wines containing more than 10 micrograms of inorganic arsenic per liter should bear an arsenic-specific warning.
The waterbodies were Dyes Inlet, Port Washington Narrows, Sinclair Inlet, Port Orchard, and Eagle Harbor. The arsenic criterion is for inorganic arsenic, but the listings were based on total arsenic data. Results showed that inorganic arsenic concentrations either did not exceed the criterion or exceeded due to natural conditions.
WASHINGTON – A draft plan by the U.S. Environmental Protection Agency that describes how the agency will assess the potential health effects of oral exposure to inorganic arsenic should take greater advantage of the robust data that exists on the chemical in order to reach the best evidence-based conclusions, says a new report from the ...

Inorganic arsenic is significantly more toxic than pentavalent arsenic compounds, arsenosugars, and arsenobetaine [Agency for Toxic Substances and Disease Registry (ATSDR) 2007b]. Arsenobetaine is a common constituent of seafood and is considered nontoxic.
Organic arsenic is the kind that is relatively safe. (Usually. There are some notable exceptions.) Inorganic arsenic is an environmental toxin, found as a contaminant in rice and drinking water.
Arsenic is naturally present at high levels in the groundwater of a number of countries. Arsenic is highly toxic in its inorganic form. Contaminated water used for drinking, food preparation and irrigation of food crops poses the greatest threat to public health from arsenic.
