Toxicity Assessment of (4<i>Z</i>)-Lachnophyllum and (4<i>Z</i>,8<i>Z</i>)-Matricaria Lactones: Implications for Environmental Safety of Bioherbicides.

ABSTRACT: (4Z,8Z)-Matricaria lactone (MAT) and (4Z)-lachnophyllum lactone (LAC) are natural acetylenic furanones with bioherbicidal potential. This study evaluates their possibilities and ecotoxicological impact on aquatic (Aliivibrio fischeri, Raphidocelis subcapitata, and Daphnia magna) and terrestrial (Caenorhabditis elegans, Lepidum sativum) model organisms. MAT exhibited rapid degradation, with 90% decomposition within 24 h and over 98% by day 16, while LAC was more stable, degrading by only 8.5% in 24 h and 67% by day 16. Despite its rapid breakdown, MAT exhibited higher acute toxicity to A. fischeri (EC₁₀ = 0.063 mg L^-1; EC₅₀ = 0.642 mg L^-1) compared to LAC (EC₁₀ = 0.524 mg L<
