Researchers discovered high levels of lead in water sources used in Flint Schools.

Researchers have been increasingly concerned about high levels of BPA in school lunches. Now, it seems like school water sources may also be dangerously contaminated.

Tests conducted at schools in Flint, Michigan, showed unsafe levels of lead in the water that had been sourced from a nearby river.

Uncovering High Levels of Lead

The levels of lead found in Flint water sources were above federal safety standards. This could be partially caused by cuts to funding for the children’s lead-screening program.

A few years ago, the Centers for Disease Control and Prevention had $29.2 million allocated to the program. The funding was then cut by 93 percent.

But cuts to the lead-screening program isn’t the only culprit.  In April 2014, the financially troubled city disconnected from Detroit’s water system, now known as the Great Lakes Water Authority, in an attempt to save money.

The city began using water from the Flint River, which had absorbed lead leaking from the pipeline. Although the budget went up to $15 million last year, the screening program for children was still cut by half.

A report from the National Center for Healthy Housing in Columbia, Maryland believes the spike in contamination is caused by the lower staff numbers, specifically for outreach and education in vulnerable populations.

“Funding goes up and down in waves,” said pediatrician Jennifer Lowry, director environmental health center at 301-bed Children’s Mercy Kansas City (Mo.) hospital, who participates in lead-screening in Kansas and Missouri.

“Kansas has no lead program,” Lowry said. “Missouri thinks it’s an important one to have.”

Effects of Lead Poisoning

Lead exposure can cause lower intelligence in children, lessen self-control in teens and cause criminal behavior in adults, said Professor T. Lyke Thompson, director of the Center for Urban Studies at Wayne State University in Detroit. The most frightening truth, however, is that the effects of lead poisoning can be permanent.

A 2011 Health Affairs analysis that calculated the societal costs of childhood lead poisoning, such as lower lifetime productivity, totaled $50.9 billion in 2008.

“Lead is ever-present in places where there is older infrastructure and older houses,” Thompson said. “You can deny its existence, but it will catch up to you.”

Dr. Mona Hanna-Attisha, a pediatrician at Hurley Children’s Hospital in Flint, compared the amount of lead present in children in 2013 to the presence in 2015. It was during this timespan that the city switched from Lake Huron water to Flint River water.

The amount of children in Flint with 5 micrograms of lead per deciliter of blood doubled since 2015. The levels present in children in Genesee County were much lower, increasing only slightly. The children who are most affected are economically disadvantaged, living in lower-income housing.

“What’s sad is there is already a disparity in lead poisoning, but now the disparity is widening,” Hanna-Attisha said.

Combating The Contamination

On Thursday, Michigan Gov. Rick Snyder created a plan that would connect the city’s water system to Lake Huron. The plan would cost $12 million to funnel water from Detroit’s system.

The plan is one of many attempts to combat lead poisoning with an increase in government spending, which requires approval from the state legislature before it can be implemented.

When the CDC cut lead safety standards from 10 to 5 micrograms per deciliter of blood, the government cut its spending.

“When they reduced it to 5, that redefined half a million children as having an elevated level,” Lowry said. “That’s the same year they took all the money away.”

If children are found with high levels of lead in their blood, investigators often inspect the home to find the source and stop the exposure.

The study was frightening, but researchers hope Gov. Snyder will make a change to the Flint water system. Flint will begin using Lake Huron water until an 80-mile, $274 million pipeline that pulls water from Genesee County is up and running next summer.

“There is no safe blood level for lead, so let’s prevent the exposure from happening in the first place,” Lowry said.

While analyzing the toxicity of student meals, researchers found that food provided by schools contains unsafe levels of BPA.

A Stanford study found harmful levels of toxic chemicals in meals prepared and provided by public schools.

Food containing BPA increases health risks for students and disproportionately impacts lower socioeconomic classes who are more likely to eat school lunches.

The Study

The study discovered that bisphenol A (BPA) had absorbed into the school food supply through the plastic or canned packages. It was spearheaded by Jennifer Hartle, a postdoctoral researcher at the Stanford Prevention Research Center.

The unique study was published in the Journal of Exposure Science and Environmental Epidemiology. Researchers attribute the presence of BPA to low-cost packaging that is used to make the food preparation process more effective while adhering to nutrition laws set by the federal government.

“During school site visits, I was shocked to see that virtually everything in school meals came from a can or plastic packaging,” Hartle said. “Meat came frozen, pre-packaged, pre-cooked and pre-seasoned. Salads were pre-cut and pre-bagged. Corn, peaches and green beans came in cans. The only items not packaged in plastic were oranges, apples and bananas.”

In conjunction with Johns Hopkins University, researchers interviewed food service personnel and visited school kitchens and cafeterias in San Francisco. They also measured the levels of BPA concentration in different food items.

Unsurprisingly, they found that BPA exposure varies depending on what the students eat.

If students have pizza, milk, fresh fruits and vegetables for lunch, they would be exposed to a minimum and tolerable level of BPA.  But if pizza and milk are eaten with canned fruits and vegetables, students could be getting up to 1.19 micrograms of BPA per kilogram of body weight per day.

Researchers suggest that finding appropriate levels of BPA for vulnerable populations like children to consume can come from experiments that measure toxicity thresholds. Although not every species may not metabolize BPA as effectively, the chemicals have a toxic impact on mice at 2 micrograms per kilogram of body weight per day.

It’s unlikely that most students consume more than 2 micrograms per kilogram per day, but the study found that those who do could ingest more than half of the amount that’s found to be toxic to animals in just one meal.

Effects of BPA Exposure

BPA is a synthetic compound that has been used to make certain plastics and resins since the 1960s.

Today, the food industry uses polycarbonate plastics containing BPA for storing food and beverages, such as water bottles and other goods. Metal cans, bottle tops and water supply lines are often coated with BPA-containing epoxy resins.

Some research has shown that BPA can seep into food or beverages from containers that are made with BPA. Exposure to BPA is a concern because of possible health effects of BPA on the brain, behavior and prostate gland of fetuses, infants and children.

The chemical effects human hormones and increases the risk of developing diseases, such as cancer or reproductive issues. Children are particularly susceptible to hormone disruption through continued exposure to BPA.

“With endocrine-disrupting chemicals particularly, there is so much uncertainty,” said Robert Lawrence, a medical doctor, one of the study’s authors and director of the Johns Hopkins Center for a Livable Future.

“We can’t tie a specific dose to a specific response like we can with lead. But we know BPA is impacting human health. Animal models are showing there can be a whole range of health effects. This research shows we should take a precautionary approach.”

The biggest impact of BPA exposure is on children who come from low-income families because they are more likely to eat federally-funded lunches. Many low-income students eat breakfast and sometimes even dinner at school. These children could be consuming extremely dangerous levels of BPA.

“Even a dose of one extra microgram per day could be a big deal,” Hartle said. “If this is an avoidable exposure, do we need to risk it? If we can easily cut it out, why wouldn’t we?”

Potential Strategies For Improvement

In addition to urging schools to provide more fruits and vegetables for students, researchers call on parents to make lunches at home.

In 1988, the U.S. Environmental Protection Agency said that 50 micrograms or less of BPA per kilogram of body weight per day is safe. Today, hundreds of scientific papers detail the dangers of BPA at levels lower than the EPA standard.

The European Food Safety Authority recently updated its standards for safe BPA intake to 4 micrograms per kilogram of body weight per day. The EPA has allowed Americans to consume 46 micrograms more than European regulators.

The study authors urge regulatory agencies to follow Europe’s lead and lower safety consumption levels. In addition, the authors call for increased funding for researching the effects of low doses of BPA. Through toxicity testing, regulators can gather concrete data and reduce overall risk to public health.

Schools should follow suit and limit BPA consumption by implementing more fresh fruits and vegetables into the student diet. Feeding children more fresh food in packed lunches and at home is also an important step in limiting exposure, according to Hartle.

But be aware that “BPA-free” items are not necessarily safer, as it is likely they possess other harmful chemicals.

“The bottom line is more fresh fruits and vegetables,” Hartle said. “There is a movement for more fresh veggies to be included in school meals, and I think this paper supports that.”
