Arsenic that is naturally occurring can contaminate the soil, just as it does the groundwater. This presents a possible arsenic exposure by use of products containing tobacco, because the tobacco plant grows from the soil and can become infiltrated with the arsenic. [3]
Arsenic is a ubiquitous naturally occurring chemical element, and the 20th most common element on Earth. [13] Arsenic levels in the groundwater vary from around 0.5 parts per billion to 5000 parts per billion, depending on an area's geologic features, and possible presence on industrial waste.
Research has not been conducted to determine whether small amounts of arsenic may play a role in human metabolism. [17] [18] However, arsenic poisoning occurs in multicellular life if quantities are larger than needed. Arsenic contamination of groundwater is a problem that affects millions of people across the world.
Arsenic is a naturally occurring element and can be found in food, water, or air. There are also industrial sources of arsenic, including mining and smelting. [8] "People are exposed to elevated levels of inorganic arsenic through drinking contaminated water, using contaminated water in food preparation and irrigation of food crops, industrial ...
The arsenic (As) cycle is the biogeochemical cycle of natural and anthropogenic exchanges of arsenic terms through the atmosphere, lithosphere, pedosphere, hydrosphere, and biosphere. Although arsenic is naturally abundant in the Earth's crust, long-term exposure and high concentrations of arsenic can be detrimental to human health. [1] [2]
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 ...
The rule in question applies to waste that’s also known as “coal ash” — which contains dangerous substances like mercury and arsenic. It requires coal plants that closed before October 19 ...
Contaminated or polluted soil directly affects human health through direct contact with soil or via inhalation of soil contaminants that have vaporized; potentially greater threats are posed by the infiltration of soil contamination into groundwater aquifers used for human consumption, sometimes in areas apparently far removed from any apparent ...
