Chronic Low Dose of Arsenic in Water Implicated in Serious Health Conditions
are well known to the lethal effects of arsenic in large doses. However, what has not been until recently clear is the ill effects of arsenic, even in smaller doses.A compilation of research sheds light on the fact that our chronic exposure to arsenic in drinking water and food may be contributing to a lot of diseases, and may be killing us slowly.
the Defense Council Natural Resources (NRDC) cites a study by the National Academy of Sciences linking drinking water contaminated with arsenic to several types of cancer, nervous system damage, cardiovascular damage and skin problems, along with possible reproductive problems and birth defects. What was not known in 1999, when this study was that even small levels of arsenic can cause great harm.
Arsenic is a natural element, and often it is used for a variety of purposes in the fields of agriculture and industry. Arsenic enters our water supply in small amounts through natural deposits found in the soil, and in large quantities through contamination of agricultural and industrial practices. Mining, copper smelting and coal burning also contribute to levels of increased arsenic. A growing number of new investigations is connected chronic exposure to low doses of arsenic in cardiovascular disease, multiple cancer, diabetes and respiratory problems in adults and children. One reason for this is interference arsenic glucocorticoid hormones in the body. One role of glucocorticoid hormones is tumor suppression.
A study that interviewed cases of death from cardiovascular problems in Bangladesh found that small amounts of arsenic can cause inflammation of the cells within the heart. Researchers often conduct related to arsenic of the population of Bangladesh studies because, unfortunately, arsenic levels are often not exceeding one part per million.
Dr. Habibul Ahsan, director of Cancer Epidemiology center and lead author of the study, says, "Bangladesh is unfortunately a living laboratory for the health effects of arsenic." In 2010, Dr. Ahsan and his research team conducted a large-scale study , which concluded that 24 percent of all deaths related to chronic disease could be traced in Bangladesh to drinking water contaminated with arsenic
While Bangladesh seems far away in the minds of many Americans, the problem is being studied. - with terrifying results - in this country too. A recent study conducted by Dartmouth College and published last July in the journal Environmental Research measured the arsenic exposure of a group of pregnant women, and a record of the frequency of sustained respiratory infections remains . their babies from the time they were born until they were four months of age
the results of this study found that the higher the arsenic exposure of the mother during pregnancy, the most common - and more serious - respiratory infections in infants were. Researchers at Dartmouth College are currently conducting a study following women from pregnancy to the growth and development of their children, assessment of their health along the way, to compare the health of children raised in families who drink supplies municipal potable water to lifted from private wells.
the current EPA standard for permitted in municipal water supplies arsenic is 10 parts per billion (ppb). However, according to information collected by the Environmental Protection Agency of the United States in 2000, as reported by the NRDC , 34 million Americans were drinking tap water 'raises cancer risk unacceptable . " It is alarming that this information was obtained only from 25 states reporting their information from arsenic to the EPA -. The actual number could be much higher
People who drink from private wells may be at risk even greater for chronic arsenic exposure, as there is no federal regulation of arsenic levels in private wells. Margaret Karagas, the lead author of arsenic study Dartmouth College, says, "if people have private wells, it is necessary to have tested for arsenic. Want to know what's in the water."
The Dr. Karagas is part of another project that is currently studying arsenic levels in foods such as apple juice and rice (which arsenic limits have been established by the federal government, and while they are low, they could accumulate ), and how the arsenic in our food supply affect the total exposure of arsenic to an individual.
the NRDC urges people to call their municipal water suppliers to obtain information on arsenic levels are contained therein. There are treatments available water in existence that can remove arsenic from a water supply, and if an area is affected, which should be made known to the municipal government to remedy the situation at once.
If you and your family drinks water from a private well, it is crucial for analysis for arsenic. In the cases of both municipal and well water, there is water filters and water distillation systems you can buy that you can remove the arsenic content. The NRDC recommends certified filters NSF International , and although specifying that such certification is not a guarantee of safety, they say, "is better than no certification at all."
water filters and water distillation systems do not last forever. It is important to periodically replace these filters. A period recommended for use time will be specified by the manufacturer, and it is important to replace your filter system or filtration, at least, this often.
Arsenic in drinking water affects everyone in this country and future generations. It is not just a problem in the third world countries - health from deteriorating effects of arsenic are coming to light here in the United States. Learn everything you can about the water you're drinking and where it comes from - the welfare of you and your family is at stake
