Effects of three tebuconazole nanopesticides on the survival of Daphnia magna

Abstract

The growing pressure to reduce excessive pesticide use has led to exploring novel formulation methods, including nanoparticle carriers for active substances.

Release and stability of two tebuconazole nanoformulations in different aquatic media

“…25 Similarly, in the case of polymeric nanoparticles within the ADaM medium (used for cultivating/ecotoxicity tests of Daphnia magna), there was a notable preservation of their colloidal properties over a 48-hour period. 27 This consistent maintenance of colloidal stability plays a significant role in ensuring uniform and continuous exposure of aquatic organisms to the nanoparticles leading to more reliable and accurate assessments of their ecotoxicological effects, as it minimizes variations in nanoparticle behavior that could otherwise skew the results. 25 Poly-ε-caprolactone (PCL) is recognized for its biocompatibility and biodegradability, making it a widely utilized polymer in diverse fields such as medical, pharmaceutical, packaging, and cosmetic industries.…”
