(1990) Ecological correlation between arsenic level in well water and age-adjusted mortality from malignant neoplasms. Cancer Res, 50, 5470-5474.Chen, C. J. and Wang, C. J. ( 1990) Ecological correlation between arsenic levels in well water and age adjusted mortality from malignant...
There are high levels of arsenic deposited in the bedrock in some states across the US. The substance contaminates the water aquifers beneath us, ending up in well water. Due to human activity, rocks, soil, and unsafe agricultural practices expose the environment to arsenic. When it rains, t...
Inorganic arsenic causes cancer, and millions of people worldwide are exposed to arsenic-contaminated water. Regulatory standards for arsenic levels in drinking water generally do not apply to private domestic wells. Reverse osmosis (RO) units commonly are used by well owners to reduce arsenic concen...
BEIJING, Jan. 2 (Xinhua) -- Algae blooms may accelerate the release of arsenic, a toxic substance that pollutes freshwater, according to a recent Chinese study. Many Chinese lakes have been plagued by eutrophication of water and outbreaks of blue-green algae in recent years. At the same time...
A program to teach data literacy to Maine and New Hampshire students by analyzing data on arsenic in well water collected from their homes has found that 25 percent of samples exceed the New Hampshire maximum safety level of 5 parts per billion (ppb) and
The level of resistance of the bacterial populations to arsenate was determined by the DVCMR bioassay, and the results showed a linear correlation with the total arsenic concentrations in the monitoring well water samples; no correlation was observed by culture methods with the methods employed. ...
Environmental Protection Agency's Arsenic Demonstration Program demonstrated three patterns of arsenic levels at the tap after arsenic treatment of the source well water. Following an initial destabilization period, Pattern A systems (6/20 with low iron/manganese in source water and plastic piping) ...
Texas and other areas. Unlike previous studies, the Texas A&M study focused on low levels of arsenic exposure (below the regulatory threshold of 10 parts per billion) in both public water systems, which are regulated by various government agencies, and private well systems, which are not ...

High arsenic levels in the water, soil, and air in the Antofagasta region in northern Chile have been criticised by Chilean scientists and doctors, who say the levels are responsible for the higher rates of cancer mortality among the local population. Death rates for lung cancer and bladder can...
