Abstract
BackgroundChemicals have deleterious effect on the environment. The wide use of nanomaterials as products for plant protection, fertilizers, and also in water purification leads to the release of these materials to the environment. Terrestrial gastropods including snails and slugs have the ability to accumulate heavy metals in their bodies. The present study evaluates the toxic effect of zinc oxide nanoparticles on the terrestrial slug Lehmannia nyctelia. Zinc oxide nanoparticles (ZnO NPs) were prepared by thermal decomposition method. ZnO NPs are characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), and ultraviolet-visible spectroscopy (UV). Slugs were treated with three different concentrations of ZnO NPs.ResultsA total of three animals died by the end of the experiment. Many histological alterations were detected after exposure to different concentration of ZnO NPs.ConclusionsThe obtained histological alterations prove the toxic effect of ZnO NPs on the animal under study.

Summary
Chemicals have deleterious effect on the environment. The wide use of nanomaterials as products for plant protection, fertilizers, and in water purification leads to the release of these materials to the environment. The present study evaluates the toxic effect of zinc oxide nanoparticles on the terrestrial slug Lehmannia nyctelia. Zinc oxide nanoparticles (ZnO NPs) were prepared by thermal decomposition method. Slugs were treated with three different concentrations of ZnO NPs. Molluscs are considered as one of the important animals in the food chain and noticed as agricultural pests. Toxic chemicals produce harmful effect on terrestrial gastropods at the cellular level (Boer et al, 1995; Hernadi et al, 1992). The common method to control this slug is the chemical molluscicides. The chemical molluscicides may cause undesirable side
