AUBURN UNIVERSITY 03/08/10 Thèse en ligne : Effect of Land-applied Arsenicals on the Soils of Alabama

Abstract: Many agricultural practices apply arsenicals directly to land through agricultural practices. Over time, repeated land-application of arsenicals may result in accumulation of arsenic in the soil. This may be problematic especially when arsenicals are added with poultry manure, which contains phosphorus and organic matter that may increase arsenic solubility. In Alabama, little is known about the consequences of repeated application of arsenicals to the soil.

570. Arsenic (WHO Food Additives Series 18)

ARSENIC Explanation The Joint FAO/WHO Expert Committee on Food Additives (JECFA) considered arsenic at its meeting in October 1966 (World Health Organization, 1967) and concluded that "until further data are obtained, the maximum acceptable lead of arsenic can be placed at 0.05 mg per kg body weight per day". The Committee was to have considered arsenic again at its meeting in April 1982 but decided (World Health Organization, 1982) to defer this item because there was not sufficient information available. The present evaluation considers the possibility of establishing a maximum tolerable daily intake according to the recommendation made by JECFA-26, 1982.

CENTER OF FOOD SAFETY (HK) - 2007 - Food Safety Focus (10th Issue, May 2007) – Incident in Focus - Arsenic in Food

http://www.cfs.gov.hk/english/multimedia/multimedia_pub/multimedia_pub_fsf_10_01.html Last month, the Consumer Council reported that some 20 samples of dried squid snacks under testing contained arsenic. The level of arsenic was particularly high in one shredded squid sample. Excessive intake, like constantly consuming three or more packs of the dried squid concerned every week for a prolonged period of time, may pose possible health risk. The findings aroused much public concern on the risk of arsenic in food. High levels of arsenic may also be found in other food products.

ATSDR - Public Health Statement: Arsenic

http://www.atsdr.cdc.gov/phs/phs.asp?id=18&tid=3 PDF Version, 154 KB This Public Health Statement is the summary chapter from the Toxicological Profile for Arsenic . It is one in a series of Public Health Statements about hazardous substances and their health effects. A shorter version, the ToxFAQs™ , is also available.
Arsenic is a naturally occurring toxic metal and its presence in food could be a potential risk to the health of both humans and animals. Prolonged ingestion of arsenic contaminated water may result in manifestations of toxicity in all systems of the body. Visual Analytics is a multidisciplinary field that is defined as the science of analytical reasoning facilitated by interactive visual interfaces. The concentrations of arsenic vary in foods making it impractical and impossible to provide regulatory limit for each food. This review article presents a case for the use of visual analytics approaches to provide comparative assessment of arsenic in various foods. The topics covered include (i) metabolism of arsenic in the human body; (ii) arsenic concentrations in various foods; (ii) factors affecting arsenic uptake in plants; (ii) introduction to visual analytics; and (iv) benefits of visual analytics for comparative assessment of arsenic concentration in foods.

Arsenic - Wikipedia, the free encyclopedia

http://en.wikipedia.org/wiki/Arsenic Arsenic ( / ˈ ɑr s ɨ n ɪ k / AR -sə-nik ) is a chemical element with the symbol As , atomic number 33 and relative atomic mass 74.92. Arsenic occurs in many minerals, usually in conjunction with sulfur and metals, and also as a pure elemental crystal. It was first documented by Albertus Magnus in 1250. [ 5 ] Arsenic is a metalloid . It can exist in various allotropes , although only the grey form has important use in industry. The main use of metallic arsenic is for strengthening alloys of copper and especially lead (for example, in car batteries). Arsenic is a common n-type dopant in semiconductor electronic devices, and the optoelectronic compound gallium arsenide is the most common semiconductor in use after doped silicon.
