Nas últimas décadas, o Brasil tem apresentado uma tendência de aumento significativo do uso de agrotóxicos. Nesse cenário, como o país é um grande produtor e exportador de alimentos, esse aumento representa um problema ambiental sem precedentes. A ocorrência de agrotóxicos no solo tornou-se um problema ambiental altamente significativo que tem sido agravado pela sua grande utilização em todo mundo e pela ausência de tecnologias de remediação com um bom custo benefício em larga escala. O destino do agrotóxico no solo pode ser afetado por características físicas, químicas e biológicas e pela forma como essas características interagem com os ecossistemas. O presente trabalho teve como objetivo fazer uma análise através de estudos realizados previamente sobre as propriedades físico-químicas do solo que atuam na dinâmica e retenção das moléculas dos agrotóxicos, afim de colaborar para estudos de monitoramento e avaliação que buscam medidas adequadas para o desenvolvimento sustentável e o alcance da neutralidade da degradação do solo.

“…Agricultural insect pests are one of the main threats that restrict stable agricultural production ( Douglas, 2018 ). Since the discovery of dichlorodiphenyltrichloroethane (DDT) in 1939, synthetic pesticides have played a vital role in mainstream commercial farming around the world ( Rezende-Teixeira et al, 2022 ). In recent years, with the increase in the frequency and time of the use of chemical pesticides, such problems as pesticide resistance and the re-emergence of insect pests have intensified, resulting in a decrease in the efficiency of insect pest control ( Abbasi et al, 2022 ).…”

RNAi technology, known as a revolutionary technology in the history of pesticides, has been identified as a very promising novel approach for crop protection, which is of great significance for achieving the sustainable agricultural development of the United Nations Food and Agriculture Organization. Although many studies have shown that RNA biopesticides have strong application prospects, its stability seriously restricts the commercial use. As the core component of RNAi, double-stranded RNA (dsRNA) is unstable in its natural form. Therefore, how to ensure the stability of dsRNA is one of the most significant challenges in realizing the commercial use of RNA biopesticides. Nanomaterials such as cationic polymers and lipofectamine can improve the stability of dsRNA in the environment, which has been proved. This paper reviews the recent research progress of nanomaterials that can be used to improve the environmental stability of dsRNA, and discusses the advantages and limitations of different nanomaterials combined with dsRNA, which provides reference for the selection of dsRNA nanoformulations.

“…Pyrethroid insecticides are synthetic chemicals derived from natural pyrethrins extracted from the flowers of Chrysanthemum, and they are more stable in the sunlight than pyrethrin. They are the second generation of insecticides which were developed mostly during World War II [ 9 ]. Due to high insecticidal effectiveness, low acute toxicity to mammals, pyrethroids are used widespread and increasing in agriculture, as well as in homes, schools, parks, apartments, and work settings to kill insects [ 10 ].…”

Hearing loss (HL) is a global health problem with a high prevalence and profound socioeconomic impact. Pyrethroids are one of the most commonly used insecticides. Although previous studies have reported the relationship between pyrethroids and neurotoxicity, little is known about the effect of pyrethroid exposure on the auditory system among the general population. This study is aimed to investigate the association of pyrethroid exposure with hearing threshold shifts of adults in the United States. A total of 726 adults, aged from 20 to 69 years from the 2011–2012 National Health and Nutrition Examination Survey (NHANES) data were included in the study. Urinary 3-phenoxybenzoic acid (3-PBA), a general pyrethroid metabolite, was used as a biomarker for pyrethroid exposure. HL was defined as a pure-tone average (PTA) at 0.5, 1, 2, 4 kHz ≥ 20 dB in the better ear. Analyses by using multivariate linear regressions were conducted to explore the associations of urinary 3-PBA with PTA hearing threshold shifts. There were no statistically significant correlations between Ln-transformed 3-PBA and either low-frequency or high-frequency hearing thresholds after adjusting for age, gender, race/ethnicity, education level, firearm noise exposure, occupational noise exposure, recreational noise exposure, serum cotinine, BMI, hypertension, and diabetes. However, associations of 3-PBA with both low-frequency and high-frequency hearing thresholds depended on age (P interaction < 0.0396 and 0.0017, respectively). Positive associations between Ln-transformed 3-PBA and both low-frequency and high-frequency hearing thresholds were observed in participants aged 20–39 years after adjusting confounders (β = 1.53, 95% CI: 0.04–3.01, and β = 3.14, 95% CI: 0.99–5.29, respectively) with the highest tertile (≥ 0.884 μg/g creatinine) of 3-PBA compared with the lowest tertile (< 0.407 μg/g creatinine). The possibility of interaction between 3-PBA and age on the hearing threshold shifts indicated that pyrethroid insecticides were prone to be more toxic to auditory system in younger adults than in older ones. Further studies will be required to confirm these findings.
