Rice imported from certain countries contains high levels of lead that could pose health risks, particularly for infants and children, who are especially sensitive to lead’s effects, and adults of Asian heritage who consume large amounts of rice, scientists said here today. Their research, which found some of the highest lead levels in baby food, was among almost 12,000 reports scheduled for the 245th National Meeting & Exposition of the American Chemical Society, the world’s largest scientific society, which continues through Thursday.

Tsanangurayi Tongesayi, Ph.D., who headed the analysis of rice imported from Asia, Europe and South America, pointed out that imports account for only 7 percent of the rice consumed in the United States. With vast rice fields in Louisiana, California, Texas, Arkansas and Mississippi, the U.S. is a major producer and exporter of the grain. However, imports of rice and rice flour are increasing ― by more than 200 percent since 1999 ― and rice is the staple food for 3 billion people worldwide, he added.
“Such findings present a situation that is particularly worrisome given that infants and children are especially vulnerable to the effects of lead poisoning,” Tongesayi said. “For infants and children, the daily exposure levels from eating the rice products analyzed in this study would be 30-60 times higher than the FDA’s provisional total tolerable intake (PTTI) levels. Asians consume more rice, and for these infants and children, exposures would be 60-120 times higher. For adults, the daily exposure levels were 20-40 times higher than the PTTI levels.”

The research was part of a symposium titled “Food and Its Environment: What Is In What We Eat?”

Tongesayi’s team, which is with Monmouth University in N.J., found that levels of lead in rice imported into the United States ranged from 6 to 12 milligrams/kilogram. From those numbers, they calculated the daily exposure levels for various populations and then made comparisons with the FDA’s PTTI levels for lead. They detected the highest amounts of lead in rice from Taiwan and China. Samples from the Czech Republic, Bhutan, Italy, India and Thailand had significantly high levels of lead as well. Analysis of rice samples from Pakistan, Brazil and other countries were still underway.

Because of the increase in rice imports into the United States, Tongesayi said that rice from other nations has made its way into a wide variety of grocery stores, large supermarket chains and restaurants, as well as ethnic specialty markets and restaurants.

Women 16-49 at Risk from Multiple Pollutants, Which Could Harm Brain Development of Fetuses and Babies

Nearly 23 percent of American women of childbearing age met or exceeded the median blood levels for all three environmental chemical pollutants — lead, mercury, and PCBs — tracked in an analysis of data on thousands of women by Brown University researchers.

All but 17.3 percent of the women aged 16 to 49 were at or above the median blood level for one or more of these chemicals, which are passed to fetuses through the placenta and to babies through breast milk.

The study, published in the journal Environmental Research, identified several risk factors associated with a higher “body burden” for two or more of these chemicals.

The three pollutants are of greatest interest because they are pervasive and persistent in the environment and can harm fetal and infant brain development, albeit in different ways, said study lead author Dr. Marcella Thompson. But scientists don’t yet know much about whether co-exposure to these three chemicals is more harmful than exposure to each chemical alone. Most researchers study the health effects of exposure to an individual chemical, not two or three together.

“Our research documents the prevalence of women who are exposed to all three of these chemicals,” said Thompson, who began the analysis as a doctoral student at the University of Rhode Island College of Nursing and has continued the research as a postdoctoral research associate for Brown University’s Superfund Research Program with co-author Kim Boekelheide, professor of pathology and laboratory medicine. “It points out clearly the need to look at health outcomes for multiple environmental chemical co-exposures.”

Most of the childbearing-age women — 55.8 percent — exceeded the median for two or more of the three pollutants.

Risks of exposure

Data were collected between 1999 and 2004 from 3,173 women aged 16 to 49 who participated in the Centers for Disease Control and Prevention National Health and Nutrition Examination Survey (NHANES). The survey was designed to represent the national population of 134.5 million women of childbearing age. Because the original study also elicited a wide variety of information on health behaviors, socioeconomic and demographic characteristics, Thompson and Boekelheide were able to identify specific risk factors associated with increased odds of having higher blood levels of lead, mercury, and PCBs.

The most prominent among them was age. As women grew older, their risk of exceeding the median blood level in two or more of these pollutants grew exponentially to the point where women aged 30 to 39 had 12 times greater risk and women aged 40 to 49 had a risk 30 times greater than those women aged 16 to 19.

Thompson said women aged 40 to 49 would be at greatest risk not only because these chemicals accumulate in the body over time, but also because these women were born in the 1950s and 1960s before most environmental protection laws were enacted.

Fish and heavy alcohol consumption also raised the risk of having higher blood levels. Women who ate fish more than once a week during the prior 30 days had 4.5 times the risk of exceeding the median in two or more of these pollutants. Women who drank heavily had a milder but still substantially elevated risk.

Fish, especially top predators like swordfish and albacore tuna, are known to accumulate high levels of mercury and PCBs, Thompson said. However, there is no known reason why they found a statistically higher association between heavy drinking and a higher body burden of pollutants.

One risk factor significantly reduced a woman’s risk of having elevated blood levels of the pollutants, but it was not good news: breastfeeding. Women who had breastfed at least one child for at least a month sometime in their lives had about half the risk of exceeding the median blood level for two or more pollutants. In other words, Thompson said, women pass the pollutants that have accumulated in their bodies to their nursing infants.

Although the study did not measure whether women with higher levels of co-exposure or their children suffered ill health effects, Thompson said, the data still suggest that women should learn about their risks of co-exposure to these chemicals well before they become pregnant. A woman who plans to become pregnant in her 30s or 40s, for example, will have a high relative risk of having higher blood levels of lead, PCBs, and mercury.

A great idea: State grants that help address health hazards in homes

Almost all homes have some kind of
indoor air quality concern.

The Minnesota Department of Health has awarded a quarter of a million dollars to seven health agencies in order to reach out to homeowners about health hazards in the home.

The initiative hopes to raise awareness of common indoor health hazards such as:

• Lead
• Radon
• Indoor air pollutants such as tobacco smoke

The funds are supposed to support local efforts  to encourage prevention activities as well as providing guidance and support.

The program builds on another initiative that is already addressing lead poisoning prevention for people moist likely to be exposed.

It was expanded because many homes that have one type of health hazard also suffer from other indoor air pollution issues, officials say.

The grants are set up to help target high-risk population groups, including young children, low-income and minorities, the elderly and areas with high levels of radon or lead hazards.

The local agencies that received a grant will set up healthy home networks in their communities consisting of professional staff, community members and other members.

The goal is to raise awareness of indoor air quality issues and to help people get healthy homes for a healthy population.

Protecting children from lead poisoning

Did you know October 23-29 is Lead Poisoning Prevention Week?

Lead poisoning can affect
children for a lifetime.

For children, lead exposure is no laughing matter.

Even low levels of exposure to lead can cause a host of developmental effects such as learning disabilities, decreased intelligence and speech, language, and behavioral problems, which can affect children for a lifetime.

Luckily, parents can protect their children - they just need to know how.

"Lead poisoning can have life-altering health effects, especially on our children. But it is entirely preventable if we take the right steps to protect our children in all the places where they live, learn and play," EPA Administrator Lisa P. Jackson said in a recent news release.

"National Lead Poisoning Prevention Week gives us the opportunity to strengthen our awareness and prevention efforts and ensure parents have the tools they need to protect their children against lead exposure every day of the year."

Avoid common sources of exposure

Children are most often exposed to lead through

• Lead-based paint
• Lead-contaminated dust in deteriorating buildings (built before 1978 and improperly renovated)

Simple ways to help protect your children:

1. Get your home tested. Have your home inspected if you live in a home built before 1978.
2. Get your child tested. Even if your young children seem healthy, ask your doctor to test them for lead.
3. Get the facts. Visit leadfreekids.org or call 1-800-424-LEAD.

Air Quality and Toxic Releases State by State: Benezene, Dioxins, Lead, Mercury, TCE

I discovered a great map on CNN's Toxic Ameria site that shows the airborne emissions of the most widespread and toxic chemicals that we're currently breathing on a daily basis basis including: Benzene, Dioxins, Lead and Lead Compounds, Mercury and Mercury Compounds as well as TCE (trichloroethylene).

All of these compounds have been associated with serious health effects including cancer and birth defects.


Many people aren't aware that a serious home air cleaner with a deep-bed activated carbon filter can remove these types of very serious airborne pollutants. In fact, our units are so reliable for airborne chemicals we've sold them to the U.S. Military, NASA and universities like M.I.T - as well as thousands of American families! See our filtration video.
