Abstract

The incorporation of lambda-cyhalothrin (LC) in lipid nanoparticles (LN) could be a sustainable strategy to increase its efficacy and decrease its hazard to the environment. The purpose of the present work was to perform the interaction between LC and LN after nanoencapsulation and to evaluate their effect on species from different aquatic trophic levels such as Aliivibrio fischeri, Raphidocelis subcapitata, Lemna minor, and Daphnia magna. LN loaded with LC (LN-LC) were produced by green and simple methodology without organic solvents using Precirol ATO5® and Capryol 90® as solid and liquid lipids, respectively, and soy lecithin and TEGO® Care as emulsifiers. The physicochemical interaction between LC and LN was assessed by differential scanning calorimetry (DSC), Fourier-transform infrared (FTIR), and X-ray, confirming that LC is associated with the lipid lattice of nanoparticles, characterized by an amorphous matrix. The data from biological tests showed no or low toxicity of LN-LC on the selected aquatic organisms. Thus, encapsulation in lipid-based nanoparticles may be a promising and sustainable choice for using this insecticide in agricultural practices, reducing its environmental risk.

期刊介绍： Aquatic Toxicology publishes significant contributions that increase the understanding of the impact of harmful substances (including natural and synthetic chemicals) on aquatic organisms and ecosystems. Aquatic Toxicology considers both laboratory and field studies with a focus on marine/ freshwater environments. We strive to attract high quality original scientific papers, critical reviews and expert opinion papers in the following areas: Effects of harmful substances on molecular, cellular, sub-organismal, organismal, population, community, and ecosystem level; Toxic Mechanisms; Genetic disturbances, transgenerational effects, behavioral and adaptive responses; Impacts of harmful substances on structure, function of and services provided by aquatic ecosystems; Mixture toxicity assessment; Statistical approaches to predict exposure to and hazards of contaminants The journal also considers manuscripts in other areas, such as the development of innovative concepts, approaches, and methodologies, which promote the wider application of toxicological datasets to the protection of aquatic environments and inform ecological risk assessments and decision making by relevant authorities.
