Dartmouth Researchers Report Finding Arsenic in Rice

A study funded by the NIEHS Superfund Research Program published today in the Proceedings of the National Academy of Sciences (PNAS) draws attention to the potential for consuming unhealthy amounts of arsenic via rice. In the study, the Dartmouth College researchers found significant differences in the urinary arsenic concentrations of pregnant women who had eaten rice in the previous two days in comparison those who had not.

 

The authors conclude that their findings highlight the need to monitor arsenic in the food supply, and note that China already has statutory limits on arsenic content in rice, but the U.S. and the E.U. do not. Rice concentrations also vary widely throughout the world and between different species and growing conditions. According to Margaret Karagas, Ph.D., one of the authors of the publication, "While this study reveals the potential for exposure to arsenic from rice, much additional research is needed before we can determine if there are actual health impacts from this source of exposure."

Superfund Research Cited in Consumer Reports

Superfund Research Program researchers from Dartmouth College, Harvard, and Columbia University are quoted in the January 2012 Consumer Reports, published online today. Consumer Reports investigators tested the levels of arsenic and lead in apple and grape juice and found that 10 percent of their samples had arsenic levels in excess of 10 parts per billion (ppb), the EPA’s standard for drinking water. One in four samples had lead levels in excess of 5 ppb, the EPA limit for bottled water. No federal standards for either chemical exist for juice.

The SRP is a long-time supporter of arsenic research, and has been funding research at Dartmouth on the health effects of arsenic since 1995. Research at Columbia University has been ongoing since 2000. Arsenic is a known human carcinogen, and exposure to low levels of these chemicals can lead to an increased risk of bladder and lung cancer.

Columbia SRP Researchers Show that Arsenic Adsorption by Sediments Could Limit Contamination

Arsenic contamination of shallow groundwater is a major public health concern both in the United States and abroad. In Bangladesh, there has been a shift in recent years to using deep groundwater, which is less contaminated, for drinking and personal use. In a study published in the October 9, 2011, online edition of Nature Geoscience, Columbia University Superfund Research Program investigators address a concern that using deep water wells will result in contamination from the shallower aquifers above. Through field studies and modeling, the researchers show that, as long as the wells are carefully managed, contamination will not occur and the water should be safe for many years to come.

Hurt and Kane Published in Nature Nanotechnology

In an article in the September 18, 2011 online edition of Nature Nanotechnology, Brown University Superfund Research Program (SRP) researchers Agnes Kane, Ph.D., and Robert Hurt, Ph.D., analyze the cellular uptake mechanisms of long fibers relevant to carbon nanotube health risks. They show that materials with a high aspect ratio, such as carbon nanotubes and asbestos fibers, cause toxicity in certain cells because their length prevents complete ingestion, which frustrates the cell. The abstract, with links to the full text of the article, can be found on the Nature Nanotechnology webpage  .

SRP Research Findings Confirm PCB Pollution Suspicions

 

Two people in protective gear adjust a cable

University of Iowa SRP researchers have reported high levels of polychlorinated biphenyls (PCBs) in the sediments along the Indiana Harbor and Ship Canal (IHSC) in East Chicago, IN. This finding poses concerns for the researchers because the canal is due to be dredged in spring 2012 to maintain shipping lanes. It is unknown what effect the dredging will have on water and air quality, but the findings showed that the deeper into the canal one goes, the higher the concentration of PCBs. "We found that the deeper you go, the more toxic it is," said Andres Martinez, a UI post-doctoral researcher and lead author of the study. "Dredging the IHSC has the potential to expose these more toxic sediments."

SRP Researcher Highlights Benefits of Federally Funded Research

On August 29, 2011, James Swenberg, Ph.D., Director of the University of North Carolina - Chapel Hill's Superfund Research Program, participated in "Multiple Benefits of Federally Funded Research" at the NIEHS campus in Research Triangle Park, North Carolina. Dr. Swenberg presented an overview of the heavy interaction between NIEHS and UNC, highlighting the university's environmental health research, as well as the robust training opportunities and community outreach facilitated by federal funding. In addition, he noted the very large financial benefits North Carolina receives from federal research support: the $112 million that UNC has received in NIEHS funding over the past 10 years has yielded anywhere from $190 to $280 million in economic impact.

 

Dr. Swenberg then participated in a panel discussion with NIEHS Director Linda Birnbaum, Ph.D.; U.S. Representative David Price; and researchers from other local institutions. Panel members acknowledged the fiscal challenges that dominate current policy discussions and indicated that scientists must be more proactive than ever in informing policy makers and the general public of the practical benefits of federally funded research.

SRP Research in Toxicological Sciences Shows that Nickel Nanoparticles May Contribute to Lung Cancer

 

Brown University Superfund Research Program (SRP) scientists released a study in the August 2011 online edition of Toxicological Sciences indicating that some nanoparticles may carry the risk of cancer. The study, led by post-doctoral researcher Jodie Pietruska, shows that exposure to nickel nanoparticles causes human epithelial lung cells to activate a pathway known as HIF-1α, which could give tumor cells a head start in cancer growth.

In the study, Pietruska compared the effects of metallic nickel and nickel oxide, as well as larger microscale particles of metallic nickel, on human lung cells. One key finding was that the nanoparticles set off the HIF-1α pathway, while the larger particles did not. The second finding showed remarkable differences in the reactions of cells to metallic nickel and nickel oxide. Upon exposure to nickel oxide, the cells died very quickly, which left no opportunity for cancer cells to develop. The metallic nickel was less likely to kill the cells, but made it easier for tumor cells to take hold and proliferate.

UNC SRP Publishes Discovery of Last Two DNA Bases in Science

 

University of North Carolina-Chapel Hill Superfund Research Program Director James Swenberg, Ph.D. published compelling findings in the July 21, 2011 online edition of Science magazine. In the article, Swenberg and his fellow researchers report on the discovery of two additional bases of DNA.

This discovery adds to the collection of four bases that make up DNA (adenine, cytosine, guanine, and thymine). Two more bases have been discovered in recent years, and Swenberg's discovery raises the list from six to eight.

The two bases, 5-formylcytosine and 5-carboxylcytosine, are versions of cytosine that have been modified by Tet proteins, which are thought to play a role in DNA demethylation. The discovery could have important implications in several areas of research, including cancer research. It could give researchers the chance to reactivate tumor suppressor genes that have been shut off due to DNA methylation.

SRP Researchers Pinpoint "Rapid Evolutionary Change" in Atlantic Tomcod

Dr. Isaac Wirgin
Dr. Isaac Wirgin

 

For nearly 30 years, two General Electric facilities dumped over a million pounds of polychlorinated biphenyls (PCBs) into the Hudson River, poisoning its inhabitants. In the February 17 edition of Science, Superfund Research Program researchers Isaac Wirgin (New York University School of Medicine) and Mark Hahn (Boston University) provide the first glimpses into how the Atlantic tomcod (Microgadus tomcod) has managed to thrive in such a harsh environment.

 

hahn_action_450.jpg
Drs. Mark Hahn and Diana Franks examine an electrophoresis gel.

Wirgin and Hahn report that the fish "have experienced rapid evolutionary change in the 50 to 100 years since the release of these contaminants." They then pinpointed the fishes' mechanism of resistance: a structural change in two amino acids in a single receptor gene, AHR2. "This is really the first demonstration of a mechanism of resistance in any vertebrate population," said Wirgin.

 

However, this resistance may come with a steep price. Though the contaminants are not toxic to the fish, they do accumulate in their bodies. Tomcod are reported to have among the highest concentrations of PCBs, dioxins, and furans found in nature. This could be troublesome, causing health effects in any predators that eat the fish—including humans. In addition, this resistance may make the tomcod more susceptible to other stressors or impair their ability to grow and develop properly.

"This research could not have been attempted without the unique multidisciplinary focus of our funding vehicle, the Superfund Research Program," Wirgin said.
