Mountain Dwellers in Argentina Have Adapted to High Arsenic Levels

Posted 13 Mar 2015 by Drugs.com

FRIDAY, March 13, 2015 – A new study appears to offer the first evidence of people adapting to tolerate the toxic chemical arsenic. Arsenic – the killer used by many murder mystery villains – is most toxic to young children and people in their prime reproductive years. The ability to metabolize arsenic quickly may been the difference between life and death in ancient times, said study leader Karin Broberg, a professor at the Karolinska Institute and Uppsala University in Sweden, and colleagues. The research included 124 women living high up in the Andes mountains of Argentina in an area where arsenic in the volcanic bedrock is released into the groundwater. For thousands of years, people in the region have been exposed to high levels of arsenic. Urine tests showed the women were able to metabolize arsenic. Genetic tests showed they had higher-than-normal rates of variants of a gene ... Read more

Arsenic in Well Water Tied to Less Brain Power in U.S. Study

Posted 8 Apr 2014 by Drugs.com

TUESDAY, April 8, 2014 – Exposure to arsenic in well water may lead to lower scores on intelligence tests, according to a study of children in Maine. Arsenic is a natural element that is found in soil and minerals, however, it can cause many health problems, and high levels of exposure can even cause death. Previous research in South Asia showed that exposure to arsenic in drinking water harms children's intelligence, but this study is the first to look at the issue in the United States. The new study included 272 children in grades 3 through 5 who were given a standard intelligence test. The youngsters lived in three school districts in Maine where household wells are the main source for drinking and cooking water. The investigators found that exposure to arsenic in well water was associated with lower intelligence scores. However, this link does not prove a cause-and-effect ... Read more

Moderate Arsenic in Environment Tied to Higher Heart Attack, Stroke Risk

Posted 23 Sep 2013 by Drugs.com

MONDAY, Sept. 23 – People chronically exposed to low to moderate levels of arsenic in their environment may be more likely to suffer a heart attack, stroke or other cardiovascular disease, a study of American Indians suggests. Previous research has linked exposure to high levels of arsenic in drinking water (more than 100 micrograms per liter) with coronary heart disease, stroke, peripheral artery disease and carotid atherosclerosis. Environmental health researchers decided to explore whether exposure to the lower levels of arsenic more commonly found in drinking water or food also would increase the risk of heart disease. "We didn't know what would happen at levels that occur regularly in the United States," said study author Dr. Ana Navas-Acien, a researcher in the department of environmental health sciences at the Johns Hopkins Bloomberg School of Public Health. Regular exposure to ... Read more

Arsenic Might Lurk in Some Organic Foods: Study

Posted 16 Feb 2012 by Drugs.com

THURSDAY, Feb. 16 – A sweetener used in many organic foods may be a hidden source of arsenic, new research suggests. Researchers at Dartmouth College also note that the sweetener, organic brown rice syrup, is found in some infant formulas. Their report appears in the Feb. 16 issue of Environmental Health Perspectives. Arsenic is a natural element that can contaminate groundwater. As the Dartmouth team explain, rice may be particularly prone to contamination because it pulls in arsenic. There are no federal limits currently set for arsenic levels in food. Study author Dr. Brian Jackson, director of the Trace Element Analysis Core Facility at Dartmouth, set out to determine the concentrations of arsenic in commercial food products containing organic brown rice syrup, including infant formula, cereal/energy bars and high-energy foods used by athletes. Jackson and his colleagues bought ... Read more

Study Sees Rice as Source of Arsenic Exposure

Posted 5 Dec 2011 by Drugs.com

MONDAY, Dec. 5 – New research finds that pregnant women in New Hampshire, which has high levels of arsenic in drinking water in some wells, may also be ingesting arsenic through rice. The study, published in this week's Proceedings of the National Academy of Sciences, did not look for any potential health problems. However, other studies have suggested that high arsenic levels in pregnant women could be linked to low birth weight and infant mortality in their babies. These new findings come a week after a Consumer Reports study found some apple and grape juice samples tainted with levels of arsenic exceeding drinking-water standards. This finding intensified a debate that began in September when Dr. Mehmet Oz, host of "The Dr. Oz Show," said that about one-third of apple-juice samples he'd tested had arsenic levels exceeding 10 parts per billion, which is the limit for drinking water. ...

Arsenic Detected in Apple, Grape Juice Samples

Posted 30 Nov 2011 by Drugs.com

WEDNESDAY, Nov. 30 – The debate over the safety of fruit juice consumed by Americans escalated Wednesday with the release of a Consumer Reports study that found many apple and grape juice samples tainted with arsenic. The researchers detected the poison at levels exceeding federal drinking-water standards in 10 percent of 88 juice samples tested. The samples involved five brands of juice sold in bottles, boxes or cans of concentrate. "This is very disconcerting on several levels. Parents should be worried," said Dr. Peter Richel, chief of pediatrics at Northern Westchester Hospital in Mount Kisco, N.Y. "Hearing this should make parents say no to juice." Most of the arsenic detected was inorganic, meaning it's known to cause bladder, lung and skin cancer. It can also up the risk of heart disease and type 2 diabetes, and some reports have stated that arsenic exposure can affect brain ... Read more

Arsenic-Containing Poultry Drug Suspended From Market

Posted 9 Jun 2011 by Drugs.com

WEDNESDAY, June 8 – A drug maker has agreed to suspend the sale of its animal drug 3-Nitro from the market because it contains organic arsenic that can be transformed into inorganic arsenic, a known carcinogen, the U.S. Food and Drug Administration (FDA) said Wednesday. The drug, also known as Roxarsone, was approved by the FDA in 1944 and has been used in broiler chickens to control coccidiosis – a disease that affects the intestinal tracts of animals – and to speed weight gain, feed efficiency and improve color of the meat. "The levels of inorganic arsenic found in chicken livers are very low and represent a very low health risk to people who eat chicken," Dr. Bernadette Dunham, director of FDA's Center for Veterinary Medicine, said during an afternoon press conference. "Consumers can continue to eat chicken as 3-Nitro is suspended from the market," she said. "Furthermore, FDA does ... Read more

Moderate Levels of Arsenic in Water Can Pose Health Threat

Posted 5 May 2011 by Drugs.com

THURSDAY, May 5 – Even moderate levels of arsenic in drinking water increases the risk for heart disease, a new study suggests. Arsenic is a naturally occuring element found in the earth's crust. High concentrations of arsenic in groundwater pose a public health threat to millions of people worldwide, according to the study. To assess the risk from moderate exposure to arsenic, researchers studied nearly 12,000 men and women in Araihazar, Bangladesh, where groundwater is contaminated with arsenic. The researchers measured arsenic levels in wells used for drinking water by the participants, who also gave periodic urine samples that were tested for arsenic. Participants were followed for about 6.6 years. The death rate from cardiovascular disease was 271 per 100,000 person years among people who drank water with moderate levels of arsenic (12 to 864 parts per billion, or ppb), compared ... Read more

Poison Experts Turn Phone Line Into a Lifeline

Posted 19 Sep 2010 by Drugs.com

FRIDAY, Sept. 17 – Trained as a registered nurse to work in emergency rooms and intensive care units, Hugh Rawls did just that until sidelined a decade ago by a back injury. Today, he's still working in emergency care, but from a different angle. For the past 10 years, he has helped man the phone lines at the Poison Control Center in Jacksonville, Fla. "In a lot of ways, there's some similarities in the critical thinking I used as a bedside nurse," said Rawls, 45. "Part of my job is not only to think about what's going on right now, but also to think three steps ahead to what could happen. I have to think ahead as to what could happen to this person and where we need to go treatment-wise." People call the center with a wide variety of problems, Rawls said. "This is very similar to working in an emergency room," he said. "You don't know what's going to come up next. One minute it's a ... Read more
