“…En Venezuela no existen regulaciones sobre los niveles de residuos de plaguicidas en suelo y los organismos multinacionales como OMS, FAO o la Unión Europea tampoco lo han establecido, por lo que es difícil establecer la forma en que estos residuos afectan la salud y calidad de vida de los trabajadores y habitantes de las zonas de producción agrícola. Dentro de este contexto, algunos autores han sugerido que la ingesta de polvo y suelo contaminado podría constituir un importante medio de exposición (Simcox et al 1995, Morgan et al 2014, Richards et al 2016 tendencia a jugar en el suelo y a llevarse las manos y otros objetos a la boca. Como término de referencia para la estimación del riesgo de exposición, se utilizan los ADI que comúnmente se emplean para los alimentos, en el entendido de que se refieren a la dosis diaria de una sustancia química que ingerida durante todo el periodo vital, parece no entrañar riesgo apreciable para la salud del consumidor, sobre la base de todos los hechos conocidos en el momento de la evaluación de la sustancia química por la Reunión Conjunta FAO/OMS sobre residuos de plaguicidas (EUFIC 2013).…”

Palabras clave: carbendazim, carbofurano, mancozeb, paraquat, agroquímicos RESUMEN La preocupación sobre la presencia de residuos de plaguicidas en suelos de uso agrícola es cada vez mayor debido a que constituyen un riesgo ambiental y una fuente de exposición humana. En este trabajo se determinó la presencia de estos residuos y el riesgo de exposición en la microcuenca Los Zarzales, municipio Rivas Dávila, Mérida, Venezuela. Se tomaron muestras de suelos en la etapa inicial, media y final de cultivos de ciclo corto, se extrajeron los principios activos y se analizaron por cromatografía líquida de alta resolución. El riesgo de exposición se estimó calculando la dosis de plaguicidas a través de la ingesta no dietética de suelo y polvo contaminado, según los criterios de la US-EPA. La mayor concentración y variedad de compuestos se registró durante la etapa media: 26 ± 7 mg/kg de residuos totales y 100 % de frecuencia de detección, destacando entre ellos paraquat (15 ± 7 mg/kg), carbendazim (8 ± 2 mg/kg), mancozeb (3.7 ± 0.7 mg/kg) y carbofurano (1.2 ± 0.5 mg/kg). Con base en estos valores, las dosis diarias calculadas fueron: 1.5, 0.8, 0.37 y 0.12 µg/día, respectivamente, todas las cuales resultaron estar por debajo de la ingesta diaria admisible establecida

“…The windbreaks were located around a variety of field crops and plantations, including: potato, carrot, peanuts, wheat and barley, vineyards, orchards and almonds (Table 1). nearby urban environments during dust storms [32,33]. These findings led us to suggest that using trees as windbreaks may not only reduce wind speed and filter out aeolian dust particles, but moreover and consequently, reduce pesticide dispersal.…”

Tree Belts for Decreasing Aeolian Dust-Carried Pesticides from Cultivated Areas

Abstract:The aim of this study was to investigate the function of tree belts in reducing the aeolian transport of dust particles carrying pesticides. The study examined the importance of the buffer zones created by commonly planted trees (Eucalyptus camaldulensis, Pinus halepensis (pine) and Ceratonia siliqua (carob)). The methods include analyzing the quantity and the chemical composition of pesticides carried by aeolian dust particles from the intensively cultivated fields and orchards, where pesticides were applied, towards the tree belts nearby. Eighteen different chemicals used as insecticides, fungicides and herbicides, were found both in the agricultural fields and in the adjacent tree belts, suggesting an important function of the trees. This ecological service has rarely been taken into consideration by management policies of tree plantings in farmland areas. To integrate this service into agriculture, especially in the case of agricultural fields and orchards, which are adjacent to populated areas, planting tree belts should be positively considered as a means for reducing aeolian dust and air pollution, mainly in order to reduce leakage of pesticides, which are a cause for significant health concerns.

“…This may be due to concentration of residues on the smaller fine particles as they present a bigger surface area and a higher organic carbon content. While the former insecticides are removed by rainfall, fipronil appears to be transformed to its biologically active intermediates on the pavement (Richards et al 2016).…”

With the exponential number of published data on neonicotinoids and fipronil during the last decade, an updated review of literature has been conducted in three parts. The present part focuses on gaps of knowledge that have been addressed after publication of the Worldwide Integrated Assessment (WIA) on systemic insecticides in 2015. More specifically, new data on the mode of action and metabolism of neonicotinoids and fipronil, and their toxicity to invertebrates and vertebrates, were obtained. We included the newly detected synergistic effects and/or interactions of these systemic insecticides with other insecticides, fungicides, herbicides, adjuvants, honeybee viruses, and parasites of honeybees. New studies have also investigated the contamination of all environmental compartments (air and dust, soil, water, sediments, and plants) as well as bees and apicultural products, food and beverages, and the exposure of invertebrates and vertebrates to such contaminants. Finally, we review new publications on remediation of neonicotinoids and fipronil, especially in water systems. Conclusions of the previous WIA in 2015 are reinforced; neonicotinoids and fipronil represent a major threat worldwide for biodiversity, ecosystems, and all the services the latter provide.
