“…Este herbicida tiene una alta solubilidad en agua y es ampliamente usado en el control pre o post emergente de hierbas, principalmente en cultivos de maíz y caña de azúcar. Su baja af inidad de adsorción en el suelo y sus recomendaciones de aplicación en zonas de riego o con altas probabilidades de lluvias, favorece la posibilidad de detección en las aguas superf iciales de la cuenca debido a procesos de escorrentía superf icial (Sandoval-Carrasco et al, 2013;Shattar et al, 2017).…”

The application of chemical products for pest control is one of the most widely used methods in agriculture worldwide despite their adverse effects on humans and the environment. This is a topic of interest due to the growing number of chemical products and their toxicity. The objectives of this research were to identify the most commercialized pesticides in the Ayuquila-Armería River basin (Mexico) and to determine their concentration in the surface water of the basin. The hypothesis of this work was that the current system of agricultural production in the basin is causing degradation of water quality due to the presence of a wide variety of pesticides. For the f irst objective, we visited 27 outlets of pesticides located in the main municipal capitals within the basin, obtaining a total of 143 commercialized active ingredients, mainly of chemical origin. For the second objective, we carried out two samplings in the dry season and two in the rainy season, in 30 sites distributed within the basin. The sampling sites were chosen in a directed way according to the problem of existing contamination and trying to cover the largest agricultural areas within the basin. The analyses were carried out through liquid chromatography coupled to mass-mass spectrometry. The results showed that 66% of the samples contained at least one pesticide. The most frequent pesticides were ametrine, dimethoate and diazinon. The sites that presented the highest number of pesticides in the four samplings were Palo Blanco, Antes Manantlán, Tuxcacuesco and Ayuquila. The sites near the area of intensive agriculture had a higher number of pesticides than those located in areas with rainfed agriculture. This study is the f irst to analyze the presence of pesticides in surface waters of the basin.

“…Also [56], used a commercial montmorillonite as a study sample, with an average pore size of 65.74 Å and a total pore volume of 0.27 cm 3 /g. These authors [57] benefits of a commercial montmorillonite pillarization with titanium oxide in pharmaceuticals adsorption and the values obtained for montmorillonite before and after modification were 65 and 216 m 2 g -1 of surface area and 0.001 and 0.08 cm 3 g -1 of micropore volume, respectively.…”

“…Shattar et al also investigated how the natural montmorillonite can be utilized in the ametryn removal by adsorption [59]. They reported an upsurge in the ametryn adsorption upon raising the initial concentration as well as operating temperature, with basic medium derailing the adsorption process, producing maximum monolayer adsorption capacity of 188.81 mg/g.…”

Background The need for environmental protection and remediation processes has been an increasing global concern. Pesticides are used as biological agents, disinfectants, antimicrobials, and also in a mixture of some chemical substances. Their modes of application are through selective dispensing and attenuation processes which act upon any pest that compete with the production, processing, and storage of foods and also in agricultural commodes. The pests might comprise weeds, insects, birds, fish, and microbes. Main body Pesticides are commonly found in water surface, landfill leachate, ground water, and wastewater as pollutant. An overview of recently studied adsorption processes for the pesticide elimination from polluted water has been reported in this study utilizing activated carbon, clay materials, biomass materials, metal organic frame work, graphene, and carbon-based materials as well as agricultural wastes as adsorbents. The risk assessment and cost analysis of adsorbents were also provided. Conclusion Evidences from literature recommend modified adsorbent and composite materials to have a prospective use in pesticide removal from wastewater. The adsorption data obtained fitted into different isotherm and kinetic models and also the thermodynamic aspect have been discussed. Graphical abstract
