“…Se ha comprobado que los plaguicidas pueden transportarse hasta sitios distintos a los que se aplican, llegando incluso a lugares más altos como montañas, bioacumulándose en pequeños mamíferos que se encuentran presentes. Se ha detectado endosulfán en regiones de alta montañas en Brasil en concentraciones de entre 0.6 hasta 144 ng/g lo equivalente a 0.000144 mg/g, estando muy por debajo de las concentraciones que se detectaron en este estudio que fueron de 0.1 mg/g (Capella et al, 2023). En la zona del Golfo de México en el estado de Campeche, se analizaron distintas especies de ratones silvestres que han estado expuestos a plaguicidas por encontrarse cerca de zonas agrícolas.…”

RESUMENEl perrito de la pradera (Cynomys mexicanus) es un roedor endémico de los pastizales del Norte de México, considerada una especie clave para el mantenimiento de su ecosistema. La principal problemática a la que enfrenta es el aumento de la frontera agrícola, por lo que se encuentra en constante exposición a productos químicos utilizados en zonas de cultivo cercanas, como los plaguicidas. El objetivo de este estudio fue detectar y cuantificar residuos de plaguicidas en muestras de suelo de colonias de C. mexicanus de los estados de Zacatecas y San Luis Potosí. Se analizaron un total de 5 muestras de suelo y se analizaron por medio de la técnica de Cromatografía Líquida de Alta Eficiencia (HPLC). Se detectaron ocho plaguicidas presentes en el 100% de las muestras analizadas, de los cuales el glifosato y el metamidofos tuvieron concentraciones mayores, de hasta 5.5 mg/g y 4.8 mg/g respectivamente. Los resultados muestran que en el suelo se encuentran altas concentraciones de los plaguicidas mencionados comparadas con las detectadas en otros estudios y mayores a la DL5O establecida para ambos. Por lo que el suelo es una fuente de exposición importante y medio para la entrada hacia el organismo de C. mexicanus. Palabras clave: suelo, plaguicidas, Cynomys mexicanus, cromatografía líquida de alta eficiencia, glifosato.

“…Por último, níveis detectáveis de pesticidas organoclorados voláteis foram reportados nos fígados de D. altimontanus e de outras espécies de pequenos mamíferos restritas às zonas mais elevadas do Parque Nacional do Itaiaia (Capella et al, 2023). Este fato sugere que o regime de uso de pesticidas nas áreas de entorno desta unidade de conservação também constitui potencial ameaça para a espécie.…”

Ano da publicação: 05/02/2024 Delomys altimontanus é endêmica do Brasil, ocorrendo nos estados de Minas Gerais, Rio de Janeiro e Espírito Santo, nos Parques Nacionais do Itatiaia e da Serra do Caparaó. Embora seja relativamente comum onde ocorre, sua população é disjunta e está presente em floresta alto-montana de 1.800 a 2.500 m, apresentando uma Área de Ocupação (AOO) de 304 km². As queimadas ocorrem em ambos os Parques e promovem declínio da qualidade do habitat. O uso turístico e o manejo de pasto realizado no entorno destas unidades aumentam a susceptibilidade dessas áreas, pois pode haver incêndios acidentais e intencionais que podem ser ainda intensificados pelos efeitos das mudanças climáticas. Por se aproximar de Em Perigo pelo critério B2b(iii), Delomys altimontanus foi categorizada como Quase Ameaçada (NT).

“…OCPs can be divided into two categories: one is chlorobenzene and its derivatives, such as dichlorodiphenyltrichloroethane (DDTs), hexachlorocyclohexane (HCHs) and hexachlorobenzene, and the other is organochlorine pesticides based on cyclopentadiene, including chlordane, heptachlor, endosulfan and so on [2][3][4][5][6][7][8][9]. OCPs have the characteristics of low volatility, stable chemical properties, not easy to decompose, long residue period, insoluble in water, soluble in fat and organic solvents, high persistence, bioaccumulation and biotoxicity [10][11][12][13][14][15]. Organochlorine pesticides are chemically stable and persist in the environment for a long time, with high residue, high enrichment and strong toxicity to organisms.…”

“…Although OCPs were widely banned in the 1970s and 1980s, they were still common in soil and groundwater [2][3][4][5], surface water [6][7][8][9], the atmosphere [17,18], ocean [19][20][21][22][23], river sediments [24], lakes [25], lake sediments [26], marine sediments [27], wetlands [28], snow [29], agricultural areas [30] and other environments. OCPs in animals [11,12], plants [12,13] and other organisms were detected, and human health was affected [14,15]. The related study focuses on spatial distribution, source identification, ecological effect, determination methods [31][32][33], degradation and removal methods [34][35][36], monitoring [37] and transport simulation [38,39], which is a hotspot in the field of environmental study.…”

Being a famous hometown of vegetables in China, Shouguang City has a long history of vegetable cultivation and is a comprehensive national commodity base for vegetables and fruits. In recent decades, with the expansion of agricultural production, the use of pesticides is increasing. Although organochlorine pesticides (OCPs) have been banned, there are still some residues in soil, groundwater and other media. The study on the migration of the OCPs in soil and groundwater is of great importance for the maintenance of food security. Using methods of hydrogeological survey, laboratory testing and numerical simulation, the spatial distribution characteristics, sources and pollution degree of OCPs in soil and groundwater were analyzed, and the migration and transformation of OCPs in soil–groundwater was dynamically simulated and predicted. The study showed that there were many kinds of OCPs residual in the soil environment. The hexachlorocyclohexane (HCHs) in the topsoil of the study area were mainly due to the use of lindane, and the main source of dichlorodiphenyltrichloroethane (DDTs) in soil was the use of DDTs in history. The contents of HCHs, DDTs and hexachlorobenzene in the topsoil of the study area were at a low level, while the content of endosulfan metabolite endosulfan sulfate was comparatively higher. In recent years, the content of organochlorine pesticides in soil has generally decreased. The indexes of OCPs in groundwater can meet the Standards for Drinking Water quality of China. It was predicted that the HCH pollutants would mainly be distributed in Gucheng Street, Shangkou Town, and its south area where the concentration exceeds 3 ng/L exceeds that of 240 km2. DDT pollutants would mainly be distributed in the east and north of Shouguang City, where the concentration beyond 0.6 ng/L exceeds that of 200 km2. Endosulfan sulfate pollutants would mainly be distributed in the Gucheng Street Office, Shangkou Town, and its south area where the concentration exceeds 1.5 ng/L will exceed that of 150 km2. Hexachlorobenzene (HCB) pollutants would mainly be distributed in Fengcheng in the west of Shouguang City and Nancha River in the northeast, where the concentration exceeds 0.2 ng/L will exceed that of 200 km2. The study enriched the monitoring data of OCPs in agricultural planting areas and provided reference for source analysis, migration prediction, and pollution prevention of OCPs.
