EPA Suspends Use of Harmful Pesticide DCPA to Protect Pregnant Women's Health and Fetal Development

The Environmental Protection Agency (EPA) has taken a significant step by issuing an emergency order to halt the use of dimethyl tetrachloroterephthalate (DCPA), a widely used herbicide that poses potential risks to fetal development. This marks the agency's first emergency action in nearly four decades. The decision was made after the EPA determined that exposure to DCPA could result in harmful changes to fetal thyroid hormone levels, leading to severe health consequences for newborns and children.

Health Risks Associated with DCPA Exposure

DCPA is utilized for weed control on various crops, including broccoli, onions, kale, Brussels sprouts, cabbage, and strawberries. Unfortunately, the EPA has found that pregnant women exposed to DCPA may experience disruptions to their fetal thyroid hormone levels. These disturbances can have far-reaching implications for the child's health, potentially resulting in low birth weight, impaired brain development, decreased IQ, and compromised motor skills later in life.

The urgency of the situation prompted Michal Freedhoff, assistant administrator for the Office of Chemical Safety and Pollution Prevention, to emphasize the necessity of removing DCPA from the market without delay. The EPA's statement underscored its commitment to protecting the public from exposure to hazardous chemicals, particularly in regard to safeguarding the health of expectant mothers and their unborn children.

Historical Context and International Precedents

DCPA has already faced international scrutiny, as it has been banned within the European Union since 2009. The EPA's decision to suspend the use of DCPA signifies a significant stride toward aligning with the precautionary measures taken by other nations to safeguard public health and the environment. This recent action reflects a growing recognition of the importance of advancing chemical safety and limiting potential risks, particularly for vulnerable populations such as pregnant women and children.

Support from Advocates and Stakeholders

The EPA's decision has garnered praise from various stakeholders, highlighting its significance for both public health and environmental protection. Mily Treviño Sauceda, executive director of Alianza Nacional de Campesinas, expressed support for the agency's historic decision, emphasizing the organization's commitment to prioritizing the health and safety of farmworker women and their communities. This endorsement underscores the broader impact of the EPA's action on safeguarding reproductive health and protecting families from the harmful effects of pesticides.

Industry Response and Regulatory Challenges

In the aftermath of the EPA's announcement, the sole manufacturer of DCPA, AMVAC Chemical Corporation, did not provide immediate comments on the suspension. The suspension of DCPA's use follows years of back-and-forth between the EPA and AMVAC regarding the herbicide's health impacts. The agency had previously requested comprehensive studies on the effects of DCPA on thyroid development in both adults and children, which took several years for the company to provide. This prolonged regulatory process highlights the challenges faced by regulatory agencies in ensuring the safety of registered pesticides.

Periodic Reassessment and Ongoing Commitment to Safety

The recent review of DCPA was part of the EPA's ongoing commitment to periodically reassessing registered pesticides every 15 years. This proactive approach aims to ensure that pesticides continue to meet safety standards and do not pose adverse health effects. The suspension of DCPA's use serves as a reminder of the importance of transparency and accountability within the chemical industry, as well as the need for timely and comprehensive data submission to regulatory agencies.

The issuance of an emergency order to halt the use of dimethyl tetrachloroterephthalate (DCPA) by the EPA marks a significant development in the agency's efforts to protect public health, particularly vulnerable populations such as pregnant women and children. The suspension of DCPA's use aligns with international precedents and has garnered support from advocates and stakeholders concerned with the harmful effects of pesticides. The decision also underscores the challenges faced by regulatory agencies and the ongoing commitment to periodically reassessing the safety of registered pesticides.
