CHICAGO — A new analysis of U.S. health data links children's attention-deficit disorder with exposure to common pesticides used on fruits and vegetables.

While the study couldn't prove that pesticides used in agriculture contribute to childhood learning problems, experts said the research is persuasive.

"I would take it quite seriously," said Virginia Rauh of Columbia University, who has studied prenatal exposure to pesticides and wasn't involved in the new study.

More research will be needed to confirm the tie, she said.

Children may be especially prone to the health risks of pesticides because they're still growing and they may consume more pesticide residue than adults relative to their body weight.

In the body, pesticides break down into compounds that can be measured in urine. Almost universally, the study found detectable levels: The compounds turned up in the urine of 94 percent of the children.

The kids with higher levels had increased chances of having ADHD, attention-deficit hyperactivity disorder, a common problem that causes students to have trouble in school. The findings were published Monday in Pediatrics.

The children may have eaten food treated with pesticides, breathed it in the air or swallowed it in their drinking water. The study didn't determine how they were exposed. Experts said it's likely children who don't live near farms are exposed through what they eat.

"Exposure is practically ubiquitous. We're all exposed," said lead author Maryse Bouchard of the University of Montreal.

BPA in Cans Poses Health Threat,
Report Claims Chemical found in 92 percent of products tested, group calls for federal ban.

TUESDAY, May 18 (HealthDay News) -- Bisphenol A (BPA), a common chemical used in the metal linings of some canned foods, poses a serious health threat to consumers and should be banned, a new report claims.

BPA is ubiquitous in plastic products, found in baby bottles and sippy cups, and it has come under scrutiny in recent years, with studies linking it to a host of health and developmental problems. This latest research looked at its presence in the metal linings of canned foods.

"We tested a wide variety of canned food products to determine whether BPA leeches from the can into the food," said report co-author, Mike Schade, the PVC campaign coordinator at the Center for Health, Environment & Justice in New York City.
Foods tested included fruits, vegetables, fish, beans, soups and tomatoes, according to the report, which was released Tuesday.

"We found BPA in 92 percent of the canned food that we tested," Schade said. "Potential exposure to BPA, not just from one can, but from meals you prepare over the course of a day with canned food, can actually expose consumers to potentially harmful levels of BPA."
So, if you prepare a meal with canned tomato, beans and fish, you may be exposing yourself to levels of BPA that have been shown in animal tests to cause health problems, Schade said.
A group representing the canned food industry took issue with the findings.

"We are extremely disappointed that in their zeal to educate consumers, the workgroup pursued a clear agenda. In doing so, it failed to provide readers with the full story on BPA in canned foods," Dr. John Rost, chairman of the North American Metal Packaging Alliance Inc, said in a statement released Tuesday.

"BPA-based epoxy coatings in metal packaging provide real, important and measurable health benefits by reducing the potential for the serious and often deadly effects from food-borne illnesses. Although the science supports the continued safe use of epoxy coatings, the industry is actively pursuing alternatives to meet growing consumer demand brought on by reports like this. However, there is simply no drop-in alternative available for the widest spectrum of food and beverages. Without a thoroughly tested substitute, the report's recommendation to forgo canned goods sacrifices a technology that has prevented food-borne illnesses for more than 30 years," Rost stated.

Schade noted there are alternatives to BPA available and some companies are starting to replace it in their cans. For example, Eden Foods has been offering food in BPA-free cans for more than 10 years, he said. Muir Glen, a subsidiary of General Mills, is planning to take BPA out of its canned tomato cans, Schade added.

Schade is also concerned that the substitutes for BPA are safe. "We are very concerned and interested in ensuring that any material that companies switch to doesn't pose any significant health hazard," he said.

There are other packaging options, including glass and non-toxic plastics, Schade said.

The goal of the report's writers is to get the U.S. Food and Drug Administration to ban BPA in food packaging. "From our perspective, BPA has no place in food packaging," Schade said.

In addition, Congress needs to act to reduce BPA exposure by banning BPA in food and drink containers. In fact, U.S. Sen. Dianne Feinstein (D-Calif.), is proposing just such an amendment to the Food Safety Act currently being considered in Congress.

Schade noted that the ban is needed because BPA is in so many products that consumers are bound to buy products that contain the chemical.

"Unfortunately, we can't shop our way out of this problem, because BPA is widespread in many different consumer products and that's why we need Congress to take action to ban BPA," he said.

Dr. Sarah Janssen, a staff scientist at the Natural Resources Defense Council in San Francisco, said that "in animal studies, exposure to BPA is associated with reproductive harm, alterations in behavior and brain development, increased risk of prostate and breast cancer, and an earlier onset of puberty."

And, she added, "The fact that BPA causes such a wide range of effects at low doses is really very concerning."

Laura N. Vandenberg, a postdoctoral fellow at Tufts University School of Medicine in Boston, said BPA is an estrogen-like hormone that can cause reproductive problems.

"BPA has been linked to so many different disease and dysfunctions that it's not safe," she said. "It's not safe in any aspect of that word."

While exposure to BPA from canned food is relatively low, "the problem is we don't know all sources of BPA," Vandenberg said. "So canned food is probably a major source, but it's now been found in air, dust, water and medical equipment. So we are being exposed from sources we don't even realize and things we can't control."

The FDA has decided to take another look at BPA, which it has continually maintained is safe for human consumption.
In January, the FDA and other U.S. health agencies pledged $30 million toward short- and long-term research aimed at clarifying the health effects of the chemical.

Report co-author Bobbi Chase Wilding, organizing director of Clean New York, said consumers can switch from canned foods to fresh and frozen foods.

"But consumers should also be reaching out to the manufacturers of the products they like and tell them that they want their cans to be free of BPA," she said.
