Abstract
Toxicological Effects of a Post Emergent Herbicide on Spirodela polyrhiza as a Model Macrophyte: A Comparison of the Effects of Pure and Nano-capsulated Form of the Herbicide
Highlights
Aquatic environment is exposed to various organic pollutions such as different classes of pesticides
The absorbance of the herbicide at 236 nm in the plant growth medium was increased during the experiment (7 d) (Fig. 4)
The findings showed that by a gradual release of the herbicide from its nanocapsules, the amount of released Gallant Super (GS) was gently increased in the treated solution during 7 d
Summary
Aquatic environment is exposed to various organic pollutions such as different classes of pesticides. One of the major causes of environmental contaminations is the wide application of herbicides and their continuous discharge to the aquatic environments via surface runoff [1]. This group of contaminants can pose an important threat and stress factor to the aquatic environment and endanger human and ecosystems' health [2]. Encapsulation of herbicides as a controlled release technology can be an effective tool for reduction of environmental contaminations [3, 4]. One of the main reasons of environmental contaminations is the broad application of herbicides Controlled release technologies such as encapsulation of herbicides are as an effective tool to reduce environmental contaminations. The aim of the present study was successful nanocapsulation of Gallant Super (GS), its characterization and compare the physiological responses of Spirodela polyrhiza L. upon exposure to GS and its encapsulated form
