Effects of PFAs during pregnancy : New research underway in New Hampshire

New research about the effects of per- and polyfluoroalkyl substances on pregnant women and young children is being performed in NH

Andrea Amico, co-founder of the community activist group Testing for Pease, said even though more is being learned nationally about the effects of PFAS exposure on the adult population, there is a gap that needs to be filled when it comes to the next generation.

“Our babies are already born contaminated,” “Children are a very sensitive population and we need to take extra precautions in examining their exposure to make sure they are safe.”

Amico said.

Officials at the Centers for Disease Control and Prevention say some studies already suggest PFAS exposure may affect growth, learning and behavior of infants and older children, as well as lower a woman’s chances of getting pregnant. In Portsmouth, Amico’s organization is working as a community liaison for a $2.6 million federally funded study that will examine the effects of PFAS on the immune systems of kindergarteners exposed to contaminated drinking water at Pease International Tradeport and on Massachusetts’ Cape Cod.

Shaina Kasper, New Hampshire state director for Toxics Action Center, said they hope this research will add to the body of knowledge on PFAS and the effects of exposure in utero and as young children. Researchers from Silent Spring Institute and Northeastern University will examine the children’s immune response before and after their kindergarten booster shots, she said.

At the Geisel School of Medicine at Dartmouth College in Hanover, Assistant Professor of Epidemiology Megan Romano is working with the New Hampshire Birth Cohort to get data for 1,000 women from the Concord and Lebanon regions. She hopes to find out more about PFAS exposure’s effects on gestational weight gain, breastfeeding and early life physical growth of children. Romano said the blood samples she is using were already collected by the cohort in 2009, when there was concern about arsenic in private water wells. The samples were taken from women between 18 and 45 years old who were between 24 and 28 weeks pregnant.

“We’re hoping to have the exposure data back some time in June. It will probably be six or seven months before we have findings we can publish,”

Romano said.

Romano said even though there is not strong evidence yet to support the theory that PFAS exposure could lead to more serious health issues for children, such as pediatric cancers, there are still many areas to explore as scientists learn more about the contaminants. The CDC says PFAS exposure can increase the risk of cancer in adults.

“I think it’s an important question for us to understand more about,”

Romano said.

Earlier this month, officials from the U.S. Environmental Protection Agency unveiled their action plan for per- and polyfluoroalkyl substances. It is the first time the agency has built a multi-media, multi-program, national communication and research plan to address an emerging environmental challenge like PFAS. EPA officials intend to establish a maximum contaminant level for PFOA and PFOS, two of the most well-known and prevalent PFAS chemicals. By the end of this year, they will propose a regulatory determination, which is the next step in the Safe Water Drinking Act process for establishing a MCL. In May of last year, EPA convened a two-day National Leadership Summit on PFAS in Washington, D.C., that brought together more than 200 federal, state and local leaders from across the country to discuss steps to address PFAS. Following that summit, the agency hosted a series of community engagement events, including one in Exeter.

Evaluating low-dose toxicity from endocrine active chemicals

Application of Systematic Review Methods in an Overall Strategy for Evaluating Low-Dose Toxicity from Endocrine Active Chemicals

A new report by the National Academies of Sciences, Engineering, and Medicine proposes a strategy that the U.S. Environmental Protection Agency (EPA) should use to evaluate the evidence of adverse human health effects from low doses of exposure to chemicals that can disrupt the endocrine system.

The report’s proposed strategy has three broad steps that can help evaluate evidence of impacts from low-dose chemical exposure:

  • Surveillance
    Surveillance can detect signals of possible health effects by actively monitoring new data, scientific literature, nontraditional information sources, and stakeholder input to ensure health effects are being identified and analyzed on a regular basis.
  • Investigation and Analysis
    To further investigate the signals, the agency should analyze existing data, generate new data to fill gaps, conduct a systematic review of evidence, or integrate evidence from human and animal studies. One or more of these options might be needed to answer questions about potential signals.
  • Action
    Possible actions the agency could take include updating chemical assessments, regularly monitoring for new data, requiring new data or models to reduce uncertainties, or updating toxicity-testing designs and practices. Additional considerations, such as the public health significance and available resources, would also factor into the decision making.

EPA’s first neonicotinoid assessment confirms risk to bees

EPA says chemical neonicotinoids can harm bee colonies in certain situations

image of honey-bee
A widely used neonicotinoid insecticide poses a risk to honey bees, EPA said.

The Environmental Protection Agency said today in a “pollinator risk assessment” that imidacloprid, a popular neonicotinoid pesticide, poses a significant risk to honeybees — but it failed to examine risks to nearly 4,000 North American native bees and all other pollinators, including imperiled butterflies, bats and birds.

” You can’t claim to do a ‘pollinator risk assessment’ and really only look at one pollinator, the honeybee,that’s not only cheating on the purpose of this work but also cheating the native bees, birds, butterflies and other species threatened by this pesticide. In fact, many of these other pollinators are even more vulnerable to neonicotinoids than honeybees. ”
said Lori Ann Burd, Environmental Health director at the Center for Biological Diversity “

Today’s analysis indicates that for some crop uses, honeybees can be exposed to imidacloprid at concentrations that negatively affect the health of the hive. But a recent Nature study found that wild bees are more sensitive to the acute toxic effects of neonicotinoids — specifically that neonicotinoid seed coatings reduce wild bee density, solitary bee nesting and bumblebee colony growth. The EPA did acknowledge that bumblebees are affected by the pesticide at much lower levels than honeybees, but it nonetheless failed to properly assess the risk.

Legislation not protecting ecosystems, EPA not regulating human pharma­ceuticals in drinking water

Drugging the Environment…

image of water-of-life
Humans have spiked ecosystems with a flood of active pharmaceuticals. The drugs are feminizing male fish, confusing birds, and worrying scientists. Water or Life by Sumit Kumar Pandit.

Klaus Kümmerer, Director of the Institute of Sustainable and Environmental Chemistry, Lüneburg, says:
Pharmaceuticals are ubiquitous in wastewater, deposited primarily from human urine and feces. The active ingredients from leftover pills thrown in patients’ trash or even hospital waste also find their way to waterways, but the contribution of those sources pales in comparison to the share “from all of us,”

Rebecca Klaper, Professor, School of Freshwater Sciences, says:
” Sewage treatment plants remove some pharmaceuticals from water during basic filtering processes, but many pass through unhindered. Metformin, for example, is stable against common water treatments such as UV light irradiation. And at this point, it is prohibitively expensive to add technologies that can filter out these chemicals. “

Kathryn Arnold, an ecologist at the University of York in the U.K., where there are also no regulations for pharmaceuticals in water, says:
” From sewage plants and landfills, drugs make their way into streams, rivers, lakes, seawater, and even into drinking water. Currently, however, the EPA does not regulate even a single human pharmaceutical in drinking water. An EPA list of pollutants that may make water unsafe, but are not regulated, includes eight hormones and one antibiotic. Metformin is not on the list. Legislation is not protecting ecosystems at the moment.  ”

Pesticide Chlorpyrifos Risks to Workers, EPA Report

EPA is releasing an assessment for public comment on the potential for human health risk of the pesticide chlorpyrifos

EPA-background image
A pesticide used on corn and other U.S. crops poses health risks to workers who mix and apply it and also can contaminate drinking water, according to a new EPA report.

The US Environmental Protection Agency EPA is releasing an assessment of people’s risks from the pesticide chlorpyrifos for public comment. The assessment updates the June 2011 preliminary human health risk assessment based on new information including public comments. EPA factored in exposures from multiple sources and considered all populations in this revised assessment. The public comment period is expected to begin in mid-January, 2015 and will be open for 60 days.

What does EPA’s December 2014 human health risk assessment show?

This assessment shows some risks to workers who mix, load and apply chlorpyrifos pesticide products. When used in large amounts in small watersheds in certain geographic areas, chlorpyrifos also shows potential risks from drinking water. There were no additional risks from chlorpyrifos in food or exposure to bystanders and workers from airborne chlorpyrifos.

What are EPA’s next steps?

EPA is developing appropriate measures to ensure that workers that use or work around areas treated with chlorpyrifos are protected and that drinking water in vulnerable watersheds is protected.
As part of the ongoing registration review for chlorpyrifos, EPA is also assessing the ecological risks from chlorpyrifos in conjunction with the agency’s Endangered Species Protection Program; the results of the preliminary ecological risk assessment are expected later in 2015.

What is the registration status of chlorpyrifos?

Chlorpyrifos remains registered while it is undergoing registration review. Registration review ensures pesticides will not cause unreasonable adverse effects when used according to label directions and precautions and that there is a reasonable certainty of no harm from dietary and residential exposure. This revised human health risk assessment contributes to understanding how chlorpyrifos may affect humans, an important part of the registration review process.

How did EPA assess risks?

EPA assessed exposure from multiple sources including those from food, drinking water, pesticide inhalation and absorption of the pesticide through the skin for all populations, including infants, children and women of childbearing age. The assessment updates the June 2011 preliminary human health risk assessment based on new information received, including public comments and a new human response model.
This is one of the first risk assessments to employ a physiologically-based pharmacokinetic and pharmacodynamic (PBPK/PD) model. This is a mathematical model that enhances our ability to assess risk by allowing us to consider variations in a chemical’s effects on a person based on such variables as age and genetics and allows us to predict how the same dose may affect various members of a large population differently. EPA has held several meetings of the FIFRA Scientific Advisory Panels to get independent advice on the relevance and usefulness that a PBPK/PD model can provide in assessing a chemical’s risks and one specifically on PBPK/PD and chlorpyrifos.

Did EPA take into account the 10x safety factor specified under the Food Quality Protection Act to protect children?

Yes, EPA did retain the 10x factor for this risk assessment. EPA believes that the PBPK-PD model in conjunction with retention of the FQPA 10x safety factor is protective of children and other vulnerable populations.

Who is at risk for chlorpyrifos exposure?

We are concerned about some workers who mix, load and apply chlorpyrifos to agricultural and other non-residential sites. We are also concerned about workers who work around areas that are treated with chlorpyrifos, even if they are not using chlorpyrifos products as part of their jobs.

What would the signs or symptoms be for chlorpyrifos exposure?

At high enough doses chlorpyrifos can cause cholinesterase inhibition in humans; that is, it can impact the nervous system causing nausea, dizziness, confusion, and at very high exposures (e.g., accidents or major spills), respiratory paralysis and death. Anyone who exhibits these symptoms should seek immediate help from a local hospital, physician, or nearest poison control center.

Can chlorpyrifos affect wildlife?

Yes, and EPA has taken actions to help protect wildlife from chlorpyrifos exposure.
For example, many of the reported incidents of wildlife mortality associated with chlorpyrifos use were related to residential lawn and termite uses and use on golf courses. The residential uses have been eliminated, termiticide uses have been restricted, and the application rate on golf courses has been reduced. Additionally, no-spray buffers around surface water bodies, as well as rate reductions for agricultural uses further reduced the environmental burden of chlorpyrifos.
The agency is currently assessing the ecological risks for chlorpyrifos in conjunction with the agency’s Endangered Species Protection Program; the results of the preliminary ecological risk assessment are expected later in 2015.

What actions has EPA taken on chlorpyrifos?

The EPA has taken a number of actions that have limited the use of chlorpyrifos since 2000. These actions include:

  • In June 2000, the Agency eliminated all homeowner uses, except ant and roach baits in child resistant packaging.
  • In 2000, EPA required that all use of chlorpyrifos products in the United States be discontinued on tomatoes. The use on apple trees was restricted to pre-bloom and dormant applications. The grape tolerance was lowered to reflect the labeled dormant application.
  • In 2002, EPA restricted the use of chlorpyrifos on citrus and tree nuts as well other crops.
  • In 2012, EPA further limited the use of chlorpyrifos by significantly lowering pesticide application rates and creating “no-spray” buffer zones around public spaces, including recreational areas and homes.

EPA sued by Nonprofits for failure to regulate Nanosilver Pesticides

Nanomaterials have proliferated in food and other consumer products with little to no oversight

There are now over 400 consumer products on the market made with nanosilver. The U.S. Environmental Protection Agency (EPA) considers silver nanoparticles a pesticide and requires products that contain – or are treated with this germ- killer – to be registered with and approved for use by the agency. But most of the nanomaterials products now on the market have not been reviewed, let alone approved by the EPA.
Two weeks ago, in an attempt to close this loophole, the Center for Food Safety, the Center for Environmental Health, Clean Production Action, the Institute for Agriculture and Trade Policy, and other nonprofits filed suit against the EPA for failing to respond to their 2008 petition, asking the agency to regulate all products created with nanotechnology as pesticides.

Are Pesticide Risk Assessments compromised by the actual Evaluation Process?

Pesticide risk assessments seen as biased, experts advise

image of Monsanto pesticide to be sprayed on food crops
The Environmental Protection Agency’s pesticide toxicity assessments often rely heavily on industry-funded studies and may omit research that could lead to different findings.

A September 2014 press release revealed that a team of ecotoxicologists from AIBS examined how the EPA (United States Environmental Protection Agency’s) carried out their evaluations on pesticide safety. The group argued that the agency’s current practices are inadequate and biased, which could potentially jeopardize the environment and the health of both humans and animals…


Pesticide use results in the widespread distribution of chemical contaminants, which necessites regulatory agencies to assess the risks to environmental and human health. However, risk assessment is compromised when relatively few studies are used to determine impacts, particularly if most of the data used in an assessment are produced by a pesticide’s manufacturer, which constitutes a conflict of interest.
Here, we present the shortcomings of the US Environmental Protection Agency’s pesticide risk assessment process, using the recent reassessment of atrazine’s impacts on amphibians as an example. We then offer solutions to improve the risk assessment process, which would reduce the potential for and perception of bias in a process that is crucial for environmental and human health.
