Randomized trial investigates biochar's effects on reducing pesticide uptake in lettuce, suggesting improved food safety.

This research aims to examine the effectiveness of biochar in reducing cypermethrin and deltamethrin uptake in lettuce.
Applied rice straw-derived biochar in varying concentrations (0%-1%) to contaminated sandy loam soil.
Measured the impact on growth metrics such as shoot length, soluble proteins, and chlorophyll levels.
Assessed pesticide concentrations in plants and evaluated health risk factors related to cypermethrin and deltamethrin.
Biochar application at 0.5% increased shoot length by 35%, soluble proteins by 43%-47%, and chlorophyll a by 34%.
Reduced malondialdehyde levels indicated lower oxidative stress, with pesticide uptake reduced to 0.05-0.06 mg kg⁻¹ at 1%.
Cypermethrin posed lower short-term (0.12) and long-term (0.14) risks compared to deltamethrin.
