Arsenic is bioaccumulative in many organisms, marine species in particular, but it does not appear to biomagnify significantly in food webs. [221] In polluted areas, plant growth may be affected by root uptake of arsenate, which is a phosphate analog and therefore readily transported in plant tissues and cells.
Inorganic arsenic and its compounds, upon entering the food chain, are progressively metabolized to a less toxic form of arsenic through a process of methylation. [7] Organoarsenic compounds arise via biomethylation of inorganic arsenic compounds, [ 8 ] via processes mediated by enzymes related to vitamin B 12 . [ 9 ]
Gold mining can contaminate groundwater with arsenic, because the element typically occurs in gold-containing ores. Gold processing releases arsenic from mine tailings, and contaminated groundwater may be unsafe to drink for decades. [7] Arsenic that is naturally occurring can contaminate the soil, just as it does the groundwater.
A new study finds that honeybees forging across the U.S. ingest local pollutants, including arsenic and lead, which are detected in their honey. More than 260 samples were taken between 2020 and ...
Following up on their November 2012 report about the "worrisome" levels of arsenic in rice products, Consumer Reports released an update this month that reveals rice products commonly eaten by ...
Many types of food contain small amounts of arsenic, such as dark chocolate, rice and seafood. Arsenic exists naturally in soil, but it also was found in chemicals sprayed on orchards for many years.
Although some European nations started banning arsenic-containing pigments in the 1830s and 1840s, Scheele's green did not completely fall out of favor until the 1860s. [21] Publicity associated with the 1861 death of 19-year-old Matilda Scheueur as a result of her job dusting artificial foliage with the pigment increased public awareness of ...
The legal action represents a challenge to a segment of the industry that produces wines that consumers can buy for less than $10 a bottle.
