Evaluation of the Aquatic Toxicity of Several Triazole Fungicides.

Fungicides play an important role in crop protection, but they have also been shown to adversely affect non-target organisms, including those living in the aquatic environment. The aim of the present study is to combine experimental and computational approaches to evaluate the effects of flutriafol, metconazole, myclobutanil, tebuconazole, tetraconazole and triticonazole on aquatic model organisms and to obtain information on the effects of these fungicides on , a freshwater plant, at the molecular level. The EC (the half-maximum effective concentration) values for the growth inhibition of in the presence of the investigated fungicides show that metconazole (EC = 0.

Assessment of the Effects of Chitosan, Chitooligosaccharides and Their Derivatives on .

Chitosan, chitooligosaccharides and their derivatives’ production and use in many fields may result in their release to the environment, possibly affecting aquatic organisms. Both an experimental and a computational approach were considered for evaluating the effects of these compounds on Lemna minor. Based on the determined EC50 values against L.

Evaluation of Ecotoxicology Assessment Methods of Nanomaterials and Their Effects.

This paper describes the ecotoxicological effects of nanomaterials (NMs) as well as their testing methods. Standard ecotoxicity testing methods are applicable to nanomaterials as well but require some adaptation. We have taken into account methods that meet several conditions.
