Insecticide resistance in malaria vectors threatens malaria prevention and control efforts. In Colombia the three primary vectors, Anopheles darlingi, An. nuneztovari s.l., and An. albimanus, have reported insecticide resistance to pyrethroids, organophosphates, carbamates, and DDT; however, the insecticide resistance monitoring is not continuous, and the data on the prevalence of resistance is scarce and geographically limited. We describe the resistance levels and intensity of previously detected resistant populations among primary malaria vectors from the most endemic malaria areas in Colombia. The study was carried out in 10 localities of five states in Colombia. Bioassays were carried out following the methodology of CDC Bottle Bioassay using the discriminating concentration and in order to quantify the intensity the specimens were exposed to 2, 5, and 10X discriminating concentrations. Five insecticides were tested: deltamethrin, lambda-cyhalothrin, alpha-cypermethrin, permethrin, and DDT. The results provide evidence of low resistance intensity and resistance highly localized to pyrethroids and DDT in key malaria vectors in Colombia. This may not pose a threat to malaria control yet but frequent monitoring is needed to follow the evolution of insecticide resistance.

“…El irca del departamento de Boyacá se mantuvo, durante cinco años, en un nivel de riesgo medio y bajo; esto pudo ser ocasionado por la escasa capacidad de gestión técnica y administrativa de los prestadores del servicio de acueducto [18] o por la alta rotación de personal que operaba las plantas de tratamiento y el bajo nivel educativo de los mismos [11].…”

“…En Colombia, los ministerios de Vivienda, Ambiente y Desarrollo Sostenible, de Salud y la Protección Social emiten normas que regulan las responsabilidades de los diferentes actores para poder ejecutar acciones de vigilancia de la calidad del agua para consumo humano. El departamento de Boyacá, a través de la Secretaría Departamental de Salud, ha desarrollado acciones de inspección, vigilancia y control relacionadas con la calidad del agua para consumo humano, con base en las competencias dadas por la Ley 715 de 2001 [8], en donde, según las diferentes categorías municipales, se asignan responsabilidades de acuerdo con lo previsto en el Decreto 1575 de 2007 [9] y la Resolución 2115 del mismo año [10,11], y dando cumplimiento a lo establecido en la Resolución 811 del año 2008, en donde se definen los lugares y puntos de muestreo para el control y la vigilancia de la calidad del agua para consumo humano [12].…”

“…Moreover, the scarcity and deterioration of water resources have been related to anthropological activities, for example, poor agriculture practices, livestock, and mining, along with accelerated industrial development and rapid population growth (Bwapwa, 2018). All these factors lead to health problems due to deficient water consumption (Guzmán et al, 2016). In developing countries, such as Peru, most diseases are caused by poor water supply (Ferro-Mayhua et al, 2019).…”

Mixed greywater treatment for irrigation uses

et al. 2020

Water contamination comes from many different sources, including, among others, factories, sewage treatment plants, mining activities (heavy metals), food-processing waste, agriculture runoff, animal waste, disposal of personal care products, and household chemicals. Therefore, the reuse of wastewater has become a fundamental strategy for sustainable water management and maintaining environmental quality. In this sense, this research presents a simple and economic alternative to solving the problems caused by greywater, resulting from laundry activities. This paper evaluates a mixed system for the treatment of greywater. The mixed system has physical filters that are composed of river stone, concrete, river sand, and coal. A bioremediation technique is also evaluated, involving two types of aquatic plants, watercress (Nasturtium officinale L.) and duckweed (Lemma minor L.). This study showed significant differences in pH reduction, from 9.56 to 7.50, total suspended solids (TSS), from 1742.00 mg/L to 298.50 mg/L, phosphates, from 1.12 mg/L PO43¯ to 0.31 mg/L PO43- , and chemical oxygen demand (COD), from 472.38 mg/L to 8.52 mg/L. Thus, the results indicate that this system is efficient for the reuse of grey water for irrigation uses. Moreover, each parameter, with the exception of dissolved oxygen and total suspended solids (TSS), meets the maximum limits set by the Environmental Quality Standards for Category 3: irrigation water for vegetables and animal beverages and the FAO irrigation water standards.
