This paper critically examines Brazil’s legislative framework for pesticide waste management, highlighting recent advancements and persistent challenges. The introduction of Law 14785/2023 marks a pivotal shift in pesticide regulation, streamlining registration processes and enhancing safety measures. This law consolidates various aspects of pesticide management, from research to disposal, aiming for more efficient oversight. Complementary to this, foundational laws such as the Federal Constitution (1988), Law 6938/1981 (National Environmental Policy), Law 12651/2012 (New Forest Code), and Law 13123/2015 (Biodiversity Law) establish broad guidelines for environmental protection and the sustainable use of resources. Specific regulations, including the Environmental Crimes Act (Law 9605/1998) and CONAMA Resolutions No. 465/2014 and No. 420/2009, address critical aspects of pesticide waste, focusing on proper disposal and soil quality management. Despite these advancements, challenges persist in the effective implementation of these laws. Inadequate monitoring systems and limited stakeholder awareness hinder regulatory enforcement. Strategic recommendations to address these issues include enhancing monitoring technologies, strengthening educational initiatives, fostering stakeholder collaboration, and adapting legislation to keep pace with technological advancements. A robust pesticide waste management system is essential for ensuring long-term sustainability in agricultural production. Inefficient disposal practices can contaminate soil and water, posing risks to biodiversity and public health. By reinforcing regulatory enforcement and integrating sustainable waste management strategies, Brazil can mitigate the environmental impact of pesticide use while promoting safer agricultural practices. The ongoing evolution of legislation reflects a commitment to sustainability; however, continuous efforts are necessary to fully realize these goals and align agricultural development with environmental conservation.

Food safety is essential to ensure that food is safe for human consumption, particularly in light of the growing global and environmental changes, including population growth and climate variations. Meeting the increasing demand for food requires enhancing and protecting agricultural systems. A common strategy is the use of pesticides, which serve to protect cultivated plants from pests, diseases, and weeds. However, improper and excessive use of these products can lead to negative impacts, spanning economic, environmental, and human health aspects. Concerns about pesticide residues in food are global, as their effects on human health vary depending on exposure and quantity. The main objective of this study was to estimate the potential residual consumption (PRC) of pesticides present in food consumed by Brazilian households. Using a specific methodology, it was identified that pineapple had the highest average PRC (121.01 mg), primarily due to the high residue of the active ingredient ethephon. On the other hand, Dithiocarbamates showed the highest residual quantity. Tebuconazole was the most repeated in the samples. It was observed that the insecticide class was responsible for the highest average PRC in households, estimated at 142.45 mg annually, while higher-income families and those located in rural areas showed a greater propensity for potential residual pesticide consumption due to the higher consumption of fruits and vegetables. Additionally, it was found that households where the head of the family is male, highly educated, and older than 40 years present a higher risk of potential residual pesticide consumption. These results highlight the need for public policies focused on sanitary inspection, the training of professionals in the field, the rational use of pesticides by producers, and proper hygiene practices by consumers to mitigate health risks.

A segurança alimentar está ameaçada pelas mudanças climáticas, pois aumentam a vulnerabilidade dos produtores agrícolas. O objetivo deste estudo foi analisar a vulnerabilidade às mudanças climáticas de agricultores familiares da região Rio Doce, Minas Gerais, Brasil, baseado nos graus de sensibilidade, exposição e capacidade adaptativa dos mesmos. A região Rio Doce abriga grande parte da bacia hidrográfica do Rio Doce. Os índices de sensibilidade, exposição e capacidade adaptativa foram calculados a partir de indicadores socioeconômicos e ambientais das propriedades. Os resultados mostraram variações de vulnerabilidade na região Rio Doce, impulsionadas por fatores climáticos, socioeconômicos e institucionais. Assim, as políticas de apoio devem ser ponderadas dentro da região.
