“…In recent years, aquaculture has become a promising activity in the search for ways to meet world food demand, expanding the production of fish and evolving into an alternative to the currently stagnant fisheries industry (FAO 2007;Thomas et al 2012). In Brazil, the availability of dammed water resources from the construction of hydropower plants and large reservoirs to supply water for urban and agricultural purposes also allows the expansion of fish farming.…”

This paper estimated the mercury (Hg), emission factor, and mass balance from caged fish farming in the Castanhão Reservoir, NE Brazil, based on monitoring of a typical farm of Nile tilapia (Oreochromis niloticus). The total Hg input to the farm reached 1.45 gHg ha(-1) year(-1), from which 0.21 gHg ha(-1) year(-1) was exported out as fish biomass, ultimately resulting in an emission factor of 1.24 gHg ha(-1) year(-1) for the reservoir or approximately 8.27 mgHg ton fish(-1) year(-1) produced. Most of the input came from aquafeeds with concentrations varying from 1.4 to 31.1 ng g(-1), depending on the type of aquafeed. The Hg concentrations in fish were very low and varied from 1.0 to 2.9 ng g(-1). These values are two orders of magnitude lower than the legal limit for human consumption. The estimated total annual discharge of Hg from farming into the reservoir is 174 g for 18,000 tons of fish produced and may reach 387 g when the reservoir reaches its total capacity (40,000 tons), which is expected to occur in 2020. The mass balance, considering the deposition and accumulation rates, showed that approximately 40% of the total Hg input accumulate in farm sediments (0.72 g ha(-1) year(-1)), which is approximately 60% of the deposition rate estimated through the sediment traps and suggests that 0.54 gHg ha(-1) year(-1) could eventually be transported out of the farm to the reservoir. Notwithstanding these facts, the total annual input of Hg from fish farming to the Castanhão Reservoir is less than 1.0% of the total input from anthropogenic sources.

“…Al estar debajo de la superficie, el plaguicida puede difundirse hacia la superficie o ser transportado por la humedad del suelo antes de que pueda escapar hacia la atmósfera, provocando daños ambientales a largo plazo, dentro de los cuales están la degradación de los suelos, la contaminación irreversible de los mantos freáticos, aguas continentales y costeras, la acumulación de los plaguicidas en las cadenas tróficas y el desarrollo de resistencia en los organismos como insectos, hongos o roedores (Edwards, 1976;Miglioranza et al, 1999;Dan et al, 2001;Barry y Warren 2004;Vives et al, 2005;Albert et al, 1989;Jiménez et al, 2005;Helberg et al, 2005;Ólafsdóttir et al, 2005;Thomas et al, 2012;Morales et al, 2017;Varol et al, 2017).…”

“…Under the surface, the pesticide may spread to the surface or be transported by soil moisture before it can escape into the atmosphere, causing long-term environmental damage, including soil degradation, irreversible contamination of groundwater, inland and coastal waters, accumulation of pesticides in trophic chains and the development of resistance in organisms such as insects, fungi or rodents (Edwards, 1976;Miglioranza et al, 1999;Dan et al, 2001;Barry and Warren 2004;Vives et al, 2005;Albert et al, 1989;Jimenez et al, 2005;Helberg et al, 2005;Olafsdottir et al, 2005;Thomas et al, 2012;Morales et al, 2017;Varol et al, 2017).…”

ResumenRecientemente se han reportado residuos de plaguicidas en el ambiente como resultado de las aplicaciones de estos productos durante varias décadas. A nivel mundial se presentan problemas atribuidos a los efectos de la contaminación por plaguicidas sobre los recursos naturales; sin embargo, en México, no existen suficientes estudios de contaminación por plaguicidas. El objetivo fue evaluar la presencia de plaguicidas en suelos de siete localidades de cinco municipios de la Comarca Lagunera en el estado de Coahuila, se realizó un muestreo de suelos a cinco profundidades (0-8, 8-23, 23-38, 38-53 y 53-68 cm) a razón de una muestra compuesta por hectárea para determinar el grado de contaminación del suelo por plaguicidas. Se utilizó el método soxhlet para la extracción de plaguicidas en la muestra y un Kuderna Danish, para la concentración. Se utilizó un cromatografó de gases. Se encontró que el díeldrin fue el único plaguicida organoclorado presente en los suelos estudiados; las capas superficiales del suelo (0-8 y 8-23 cm) mostraron las mayores concentraciones de díeldrin. El AbstractPesticide residues have recently been reported in the environment as a result of applications of these products for several decades. Globally, there are problems attributed to the effects of pesticide contamination on natural resources; however, in Mexico, there are not enough studies of pesticide contamination. The objective was to evaluate the presence of pesticides in soils of seven localities of five municipalities of the Comarca Lagunera in the state of Coahuila, a soil sampling at five depths (0-8, 8-23, 23-38, 38-53 and 53-68 cm) at the rate of a composite sample per hectare to determine the degree of soil contamination by pesticides. The soxhlet method was used for the extraction of pesticides in the sample and a Danish Kuderna for the concentration. Gas chromatography was used. It was found that dieldrin was the only organochlorine pesticide present in soils studied; the superficial layers of the soil (0-8 and 8-23 cm) showed the highest concentrations of dieldrin. The organic matter content, clay percentage and pH of the soil were the most influential characteristics on 1692 Rev. Mex. Cienc. Agríc.

“…Therefore, increasing agricultural production has resulted in increasing number of aquatic systems being impacted by the contaminants present in wastewater releases (Figueiredo-Fernandes et al 2007). It is well known that the pesticide application could represent a contaminant source for the aquatic environment and thus, affect aquatic fauna and in particular, fish (Pathan et al 2010;Botaro et al 2011;Thomas et al 2012;Wang et al 2013;Agbohessi et al 2014;Karthigayani et al 2014;Barnhoorn et al 2015). Factors to be considered in this regard are pesticide persistence in the environment and their potential for bioaccumulation and biomagnification in the food chain (Muthukumarave et al 2013;Rathnamma and Nagaraju 2014).…”
