Ion Exchange Chromatography for Trace Ionic Analysis in Water
Feb. 1, 2008 -- There are fewer food sources of iodine in the American diet than there were just a few decades ago, raising the risk of iodine deficiency in a growing number of people. So says a researcher who calls himself an "iodine activist."
Cow’s milk in Japan contains more perchlorate than U.S. milk, even though Japan lacks an extensive military–industrial base, according to new research published today on ES&T’s Research ASAP website (DOI: 10.1021/es061429e). The study could put an end to the notion that widespread low-level perchlorate contamination comes mainly from military sources.
The 2005 ES&T environmental science paper of the year finds that perchlorate is everywhere.
It began with a phone call in 2003 from the Texas Commission on Environmental Quality. The commission was investigating a case of perchlorate contamination in West Texas groundwater: Could Texas Tech University (TTU) help out? W. Andrew Jackson, an associate professor in the department of civil and environmental engineering, fielded the call and said yes.
High levels of perchlorate found in U.S. mothers’ milk
The first sampling of perchlorate in breast milk from nursing mothers in the United States reveals levels as high as 92 parts per billion (ppb), which expose infants to concentrations of the contaminant that are 20 times higher than the safe dose recently recommended by a National Academy of Sciences (NAS) committee.
Texas chemists show evidence for a natural atmospheric origin of perchlorate. For many, perchlorate is almost synonymous with the rocket fuel that has made it into U.S. groundwater and surface water and subsequently into foods such as lettuce and milk. In the human body, perchlorate inhibits the transport of iodide, which could lead to hypothyroidism.
When scientists started identifying perchlorate in drinking water and food, the U.S. Department of Defense’s use of perchlorate as an oxidizer in explosives, pyrotechnics, rockets, and missiles was thought to be largely responsible. Chilean nitrate fertilizer (CNF), which is used on some U.S. farms, was another likely source. But the breadth of contamination, sometimes at low levels and in areas without munitions or agricultural use of CNF, suggested that other sources might be responsible.
Now available: Chemiluminescent Analyzer for Arsenic in Water
Wading through the scientific literature does eventually pay off. In the October 15 issue of Analytical Chemistry (pp 7088–7097), Purnendu “Sandy” Dasgupta and colleagues at Texas Tech University and the U.S. Geological Survey bring back a chemiluminescent reaction, last described in the literature more than a decade ago, to quantify two inorganic species of arsenic, As(III) and As(V), in water. The measurement is completed in 4– 6 min in an automated instrument with only 3 mL of water.
Fertilizer From Chile Puts Perchlorate on the Table
Researchers recognize three major sources of perchlo rate in the food chain: mili tary– industrial activities, agricultural use of Chilean nitrate fertilizer, and natural atmospheric sources. The relative magnitude of each source has long been subject to speculation. New research published in this issue of ES&T (pp 6608–6614) shows that the historical use of Chilean nitrate fertilizer is as large a source of perchlorate in food as military–industrial activities are, with natural atmospheric sources coming in far behind.
The delightful iridescence and evanescence of soap bubbles arises from the fact that their walls are nothing but a film of water sandwiched between two layers of surfactant molecules. This unusual construction also endows soap bubbles with a uniquely large ratio of surface area to contained liquid. Tinakorn Kanyanee et al. (Anal. Chem. doi:10.1021/ac052198h; 2006) set out to exploit this feature — by 'wiring up' soap bubbles and using them as the functional heart of a fully automated detection system for trace gases.
Soap bubbles may be notoriously delicate and short-lived, but Purnendu Dasgupta of Texas Tech University, Lubbock, thinks that they could make highly useful tools for analytical chemistry. He has already developed a device that can detect sulphur dioxide by measuring the electrical conductivity of a captured soap bubble, and is now in the process of using bubbles as the basis for an entirely novel separation system.
Soap bubbles consist of a layer of water sandwiched between two layers of soap molecules, which, like all surfactants, possess a hydrophilic (water-loving) end and a hydrophobic (water-avoiding) end. The hydrophilic ends point towards the water layer and the hydrophobic ends point away from it.
A long-standing collaboration between two analytical chemists, one at the University of Washington (UW) in Seattle and the other at Chiang Mai University (Thailand),led to an international meeting that has furthered ties between researchers in the two countries.
Chemiluminescence Determines Whether Water Is Safe
Arsenic does not just kill people in murder mysteries. The metalloid is poisonous, and long-term exposure at low levels leads to health problems such as skin, bladder, lung and prostate cancer. Arsenic exposure has been linked to a host of other ailments and developmental problems
Chemist Sandy Dasgupta has found that compounds in a person’s breath hold clues to the diagnosis and treatment of disease You arrive at the clinical laboratory with doctor’s orders for a laundry list of tests. The lab technician takes the paper and hands you a bright red balloon. You blow it up, twist it closed, hand it back and leave. There’s no need for urine samples, blood tests or other invasive procedures. The laboratory will analyze your exhaled breath and provide your doctor with a report on health conditions like diabetes and high cholesterol. That reality might not be too far away.
There's nothing like a toy recall to take the twinkle out of playing Santa Claus.
It seems as if everyday a new toy recall is announced because of lead contamination. That's left some parents wondering what they can safely buy for their children this Christmas.
The U.S. population should not rely on
salt to provide enough iodine, according to the first survey of iodized
salt from U.S. homes. More than half of 88 iodized salt samples
analyzed contained less than the amount of iodine recommended by the
U.S. Food and Drug Administration (FDA). The results, published in
ES&T (DOI: 10.1021/es0719071)
by chemist Sandy Dasgupta at the University of Texas Arlington and
colleagues, have implications for pregnant and nursing women as well as
for children.
First evidence that a common pollutant may reduce iodine levels in breast milk
Researchers in Texas are reporting the first evidence from human studies that perchlorate, a common pollutant increasingly found in food and water, may interfere with an infant's availability of iodine in breast milk. Iodine deficiency in infants can cause mental retardation and other health problems, the scientists note. The study also provides further evidence that iodine intake in U.S. mothers is low and that perchlorate may play a key role.
In a study scheduled for the November 1 issue of ACS' semi-monthly Environmental Science & Technology, Purnendu Dasgupta and colleagues note that perchlorate occurs naturally in the soil and is also manufactured as a rocket fuel and explosive ingredient. Past studies showed that perchlorate can inhibit iodine uptake. However, scientists did not know its effects on iodine levels in the milk of nursing mothers.
To find out, the researchers collected breast milk samples from 13 breastfeeding mothers and measured their content of iodine, perchlorate, and thiocyanate, another iodine inhibitor found in certain foods. The study showed that if these breast milk samples were fed to infants, 12 of 13 infants would not have an adequate intake of iodine. It also showed that nine of the infants would have ingested perchlorate at a level exceeding those considered safe by the National Academy of Sciences. "Even though the number of subjects was not large, in terms of the number of total samples analyzed, this is the most extensive study on the topic," the researchers say, adding that the low iodine levels are "disconcerting."
