  • Chemical Concerns – Insights on Air Pollution, Public Health, and Chemical Safety

    Richard Denison, Ph.D., is a Lead Senior Scientist.

    Yesterday Environmental Defense Fund (EDF) filed more than 100 pages of comments on a 40-page draft risk evaluation the Trump Administration’s Environmental Protection Agency (EPA) has prepared for Pigment Violet 29 (PV29).  PV29 is the first of 10 chemicals undergoing risk evaluations under the Toxic Substances Control Act (TSCA).  Our comments were so much longer than the EPA document we were commenting on because there was far more to say about what information EPA failed to obtain, make available or consider than what EPA included in its draft.

    The essence of our lengthy comments can be boiled down to a single sentence, however:  EPA has utterly failed to demonstrate that PV29 does not present unreasonable risk of injury to health or the environment.

    For folks who want somewhat more detail than this, our comments start with a 4-page Executive Summary that capsulizes the many serious deficiencies we identified in EPA’s draft.  I’ll provide some highlights in this post.   (more…)

    It has been more than 18 months since EDF and other advocates challenged the Food and Drug Administration’s (FDA) May 2017 decision to continue allowing perchlorate in dry food plastic packaging and food handling equipment.

    While Congress gives FDA 180 days to act on food additive petitions, FDA must act “as soon as possible” on a challenge such as ours. However, the agency has yet to complete a review of its May 2017 decision in light of our concerns and evaluate whether to either stand by it, or reverse it. We did not expect FDA would take three times longer to review a decision already made, especially since our objection is largely based on the agency’s own data.

    In the meantime, perchlorate in food continues to threaten children’s brains. The chemical, a component of rocket fuel, disrupts the thyroid gland’s normal function and reduces production of the thyroid hormone needed for healthy fetal and child brain development. FDA’s own studies show increased levels of perchlorate in foods such as baby food dry cereal, indicating the chemical’s intentional use in dry food packaging is the likely source of increased exposure for young children.

    How FDA got it wrong

    In FDA’s May 2017 decision to continue allowing intentional use of perchlorate in contact with dry food, the agency largely relied on flawed science to assess dietary exposure. Its three central errors were:

    1. Ignoring its own data showing significantly increased exposure for children;
    2. Woefully underestimating exposure based on a flawed migration test; and
    3. Unrealistically assuming that perchlorate-laden plastic would only contact food once.

    [pullquote]“LSL replacement initiatives should address barriers to participation so that consumers served by LSLs can benefit equitably, regardless of income, race or ethnicity.”

    – A founding principle of the Lead Service Line Replacement Collaborative[/pullquote]States and communities across the country are taking important steps to accelerate replacement of lead service lines (LSLs) – lead pipes connecting the water main under the street to homes and other buildings. As part of this progress, many programs have strictly limited the standard practice of partial LSL replacement – replacing only the portion of the LSL on public property, which commonly arises when rehabilitating the main and reconnecting the existing line. Partial replacement is likely to increase, at least temporarily, lead levels in drinking water in homes and may not reduce lead exposure in the long run.

    The default approach for most water utilities rehabilitating their main has been to simply alert property owners to the risk of partial replacement and advise them to hire a contractor to voluntarily replace the remaining portion of the LSL on their property.

    Other utilities have rejected this approach and gone further to protect residents. For example, Washington, DC offers to coordinate private side and public side replacement to reduce costs and make participation easier but still expects the property owner to pay for the private side. Others, such as Cincinnati, OH, have required full LSL replacement, providing a significant subsidy to the homeowner and allowing the cost to be spread over ten years through a property tax assessment. Indiana American Water and Philadelphia, PA go even further and pay for the cost of full LSL replacement out of ratepayer or capital improvement funds. States are acting too, with Michigan requiring utilities to pay the cost of replacement on private property and Wisconsin requiring cost sharing. For more examples, see our webpages recognizing communities and states that are leading the way.

    We blogged before the holiday break about how EPA used a single, unverified and conflicted estimate of worker exposure to build a whole house of cards and then used it to conclude that Pigment Violet 29 (or PV29) poses no risk to human health.

    But upon further consideration, we need to issue a correction:  It’s not a house, it’s a veritable skyscraper of cards EPA has constructed.  That’s because EPA took its highly suspect worker exposure level and combined it with a hazard value EPA erroneously asserts demonstrates minimal hazard, in violation of its own and other authoritative guidance.   (more…)

    We recently finished a round of updates to our webpages recognizing states and communities leading the way in efforts to accelerate lead service line (LSL) replacement across the country. As we start the New Year, we wanted to summarize the good news from 2018 and highlight some opportunities for more success.

    Ninety-five communities are leading the way on LSL replacement programs:[1]

    In October 2018, the Food and Drug Administration (FDA) banned the use of lead acetate in hair dyes in response to a March 2017 color additive petition from EDF and other health advocates. In December, we learned that Combe, Inc., the maker of the lead-acetate based hair dye Grecian Formula, objected to FDA’s decision, requested a formal evidentiary public hearing to review the decision, and claimed the use is safe. The objection puts the FDA’s decision on hold awaiting a process that may take years to resolve. Apparently, the company thinks it is safe for men to slather skin-soluble lead on their head every couple of days and to risk exposing their families to a heavy metal for which no safe level of exposure has been identified.

    Combe’s action was somewhat surprising because the company told CBS News that it removed lead acetate from its Grecian Formula “quite a long time ago,” but was unable to provide an exact date. Presumably, someone in the know updated the product’s Wikipedia page, which says Grecian Formula does not contain lead acetate as of July 2018, although an earlier version of the page said April 2018.

    Whatever the date it was reformulated, why would Combe block FDA’s decision when it has long sold a lead-free brand – Just For Men – and had already reportedly removed lead from Grecian Formula? From a market standpoint, objecting to FDA’s decision benefits Youthair, Combe’s main competitor, which continues to sell a leaded-version of progressive hair dye.
