The dismissal of prominent Argentine scientist Virginia Aparicio has sent shockwaves through the country’s academic and environmental research communities. Fired in late October from the National Institute of Agricultural Technology (INTA, for its Spanish initials) following an administrative investigation, Aparicio and her supporters argue that her termination is a case of blatant political persecution. The disciplinary action stems from her involvement in a high-profile international study investigating the human and environmental impacts of agricultural chemicals—research that revealed widespread pesticide exposure among Argentine participants and raised profound public health concerns.
Aparicio, a respected agricultural scientist with a PhD and more than two0 years of service at INTA, as well as being a researcher for Argentina’s National Scientific and Technical Research Council (CONICET), received the harshest disciplinary sanction available under the nation’s public employment laws. Signed by Nicolás Bronzovich, president of INTA’s Board of Directors, Resolution No. 366 permanently removes Aparicio from the institute and bars her from holding any position within the country’s national public administration for at least five years.
The disciplinary fallout is the culmination of a tense year-long conflict between the researcher and the state agricultural agency. The investigation that led to her dismissal was launched in December 2023, just months after INTA blocked a scheduled public presentation of research findings from an international project known as SPRINT (Sustainable Plant Protection Transition: A Global Health Approach). The controversial findings pointed to significant chemical contamination in humans and the surrounding environment, triggering a severe institutional backlash that has ultimately culminated in her ouster.
The Reasons INTA Gave for Her Dismissal
The core of the dispute centers on the SPRINT project, an expansive international research initiative launched in 2020 and funded by the European Union. Coordinated by Wageningen University & Research in the Netherlands, the project was designed to assess the complex impacts of pesticides and their chemical mixtures on human health, plants, animals, and the broader environment across various agricultural regions.
As part of this global effort, Aparicio and her research team in Argentina gathered extensive data that yielded deeply troubling results regarding pesticide exposure in the country. In 2023, the study detected glyphosate—one of the most widely used herbicides in global agriculture—in nearly 90% of human blood samples tested. Furthermore, chlorpyrifos, an organophosphate insecticide, was found in 37.7% of the samples. Beyond human biomarkers, the research team identified pesticide residues across a wide array of environmental indicators, including surface water, ambient air, household dust, food supplies, and local soil.
Rather than embracing the findings as critical public health data, INTA moved swiftly to distance itself from the project. In June 2023, the institute suspended the public presentation of the results, withdrew its institutional participation from the international project, and subsequently removed Aparicio from her role. By December 2023, INTA had initiated formal disciplinary proceedings against her, which concluded with the Board of Directors approving her dismissal this October.
According to Resolution No. 366, Aparicio was accused of violating laws that prohibit public officials from using their authority for purposes unrelated to their official duties, alongside allegations concerning the improper use of state resources. Specifically, INTA’s leadership questioned the logistical handling of human biological samples collected during the study. While the original framework stipulated that analysis should take place domestically, biological samples were shipped to laboratories overseas without clear documentation of the requisite institutional authorizations, with project funds utilized to cover the associated shipping expenses.
Additionally, the administrative investigation raised concerns regarding the involvement of former researcher José Luis Costa, who is Aparicio’s partner and no longer maintained an active institutional affiliation with INTA. According to the board, Costa was allegedly assigned coordination responsibilities and given access to confidential project information without formal authorization. INTA also scrutinized the management of European Union grant funds and the substitution of the ethics committee specified in the original agreement with an external body.
Despite these administrative accusations, the board’s decision acknowledged that Aparicio did not personally profit from the alleged misconduct and noted that she possessed no prior disciplinary record throughout her lengthy career at the institute. Nonetheless, the resulting penalties represent a total professional exclusion from the Argentine public sector.
What Aparicio and Her Defense Have Said
In the wake of her dismissal, Aparicio turned to social media to rally public support and denounce the institutional actions taken against her. In a video posted to Instagram on October 28, she detailed the sequence of events that led to her ouster and appealed directly to the volunteers who made the research possible.
"A campaign was then launched to discredit both the research and my role within it," Aparicio said in her video statement. "The inquiry concluded with my dismissal from the public service, a decision handed down by INTA’s Board of Directors and its president."
Expressing her deep appreciation for the backing she has received from colleagues and the public, she urged supporters to maintain their solidarity. "I am infinitely grateful for all that support, and I ask that you continue to stand with me; INTA must be held accountable for violating the rights of the volunteers who participated in this project—volunteers to whom we owe the information we now possess," she added.
Legal representation for the scientist moved immediately to contest the board’s ruling. Mario Bolla, Aparicio’s attorney, announced plans to file a legal challenge in the federal court of Mar del Plata aimed at annulling the sanction and restoring her right to work. Bolla sharply criticized the severity of the punishment, emphasizing that the ban on public-sector employment extends far beyond her specific research activities at INTA, effectively sidelining a leading expert on environmental toxicology.
Furthermore, Bolla highlighted that the disciplinary measure carried implications that stretched well beyond an individual employment dispute. By suppressing the dissemination of the study’s findings and barring Aparicio from even meeting with the study’s participants, the state was infringing upon broader societal rights.
"This measure is not only destroying the career of an outstanding scientist; it is also violating the public’s right to access environmental information and information concerning public health—obligations undertaken by the Argentine State when it ratified the Escazú Agreement into law," Bolla told the outlet Página 12, pointing to international legal commitments regarding transparency and environmental democracy.
The controversy steadily intensified throughout the year as rumors and preliminary reports circulated regarding the impending termination of her contract, drawing broader national scrutiny to the intersection of agricultural policy, scientific freedom, and government accountability in Argentina.
What the Argentine Scientific Community Says
Throughout the disciplinary process, professional associations, academic institutions, and labor unions have voiced fierce opposition to INTA’s actions. Many within the scientific community have characterized the proceedings not as a routine administrative correction, but as politically motivated censorship designed to suppress uncomfortable truths about the environmental and health consequences of Argentina’s dominant agricultural production model.
Critics point to several unprecedented aspects of the case to support claims of persecution. Notably, they highlight that this is the first dismissal of its kind in INTA’s 70-year history, noting the stark contrast between the severity of the sanction and Aparicio’s lack of personal enrichment or prior disciplinary infractions. The decision to block the public presentation of the SPRINT data is viewed by her peers as a direct assault on the fundamental tenets of scientific inquiry.
Institutions such as the National University of Río Negro and the Confederation of Education Workers of the Argentine Republic (CTERA) issued public statements condemning the dismissal. The concern has also resonated deeply among the citizens who participated as subjects in the biomonitoring research.
"Large quantities of pesticides were found in my body, and I demand an end to the persecution of our colleague Virginia Aparicio," said Nair Pereira, a SPRINT volunteer and CONICET researcher, in a video distributed via the social media campaign account Todxs por Virginia.
Ana Velez, another CONICET researcher, echoed those sentiments in a separate video message. "No to the dismissal of Virginia Aparicio, and enough with the persecution of the scientific community," Velez said.
For her part, Aparicio has maintained a steadfast focus on the broader implications of her case for academic freedom and public welfare in Argentina. Emphasizing that environmental and health data must remain accessible to the citizenry, she continues to advocate for transparency.
"We must recognize that in a democracy, we cannot tolerate censorship, persecution, or the suppression of the freedom to conduct research," Aparicio stated in her video address. "Science is countered with more science, not with less."
