Horticulture affects macroinvertebrate assemblages in adjacent streams (Buenos Aires, Argentina)

Abstract: The agrochemicals used on crops can reach watercourses, affecting water quality and biologic communities. The aim of this research was to study the effects of horticulture on the water quality and invertebrate assemblages of adjacent streams in Buenos Aires province, Argentina. Four streams draining horticultural basins were compared with another four considered less disturbed: two of the latter located in a Biosphere Reserve and the other two in extensive livestock-raising basins. Pesticides were detected in … Show more

“…Del Gato and the Carnaval RWs are in the agricultural area surrounding La Plata, the capital of the Province of Buenos Aires. This area is one of the main horticultural regions in the country (Baldini et al 2019) with a high productivity based on intensive use of fertilizers and pesticides along with greenhouse technology (Arias et al 2020). Downstream, the Carnaval and Del Gato streams run through densely populated areas and their channels have been heavily impacted by anthropic action.…”

“…The other RWs, Cajaravillas and Chubichaminí, are located in Magdalena, a rural area with extensive livestock grazing on natural grassland (0.7 cows per ha., Gómez et al in press). Freshwater systems surrounded by these grasslands are considered the reference for the region Arias et al 2020;). These RWs receive groundwater and surface water, with a greater volume being supplied by the former.…”

“…Diferentes autores han estudiado el ensamble de macroinvertebrados de la región pampeana en arroyos (Rodrigues Capítulo et al, 2001Cortelezzi et al, 2011;Ocon & Rodrigues Capítulo, 2012;Solis et al, 2016;Arias et al, 2020;Marrochi et al, 2021) y más recientemente en humedales (Rodrigues Capítulo et al, 2020a;Cortese, 2021;Solis et al, 2021;Altieri et al, 2022). Aunque parte de estos estudios han tenido en cuenta el análisis de los GFA, el estudio desde el enfoque de las redes tróficas ha sido menos considerado (López van Oosterom et al, 2013;Ocon et al, 2013;Marchese et al, 2014).…”

“…De la superficie cubierta por invernáculos, 45 % de los mismos se encuentran a una distancia menor a los 200 metros de algún arroyo. Además, la alta productividad del área está basada en el uso intensivo de fertilizantes y pesticidas que llegan a estos cuerpos de agua y afectan a la fauna (Sarandón, 2002;Arias et al, 2020). Los principales cultivos del cordón frutihortícola son: la lechuga, el tomate, el alcaucil, la acelga, la espinaca, el maíz dulce, el pimiento, el brócoli y el repollo; y dentro de los fertilizantes más utilizados se pueden mencionar la urea, el nitrato de amonio (UAN), el fosfato di amónico, el fosfato mono amónico y diferentes mezclas, además se aplican diferentes tipos de herbicidas, insecticidas y fungicidas (Sarandón et al, 2013).…”
