Multi-matrix baseline monitoring of toxic metals and targeted pesticide residues in a highland vegetable agroecosystem, southern Lao PDR: Implications for adaptive surveillance design
This pilot study in southern Lao PDR establishes a baseline for toxic metals and pesticide residues in highland vegetable agroecosystems, revealing undetected targeted pesticides due to potential analytical mismatches, low-level metal contamination varying by matrix and crop morphology, and the critical need for adaptive, context-specific surveillance strategies.
