Heavy metal accumulation and antioxidant properties of Nephrolepis biserrata growing in heavy metal-contaminated soil

by

FAZILAH ABD MANAN et al. View all

Hazardous Substances and Risk Analysis

Antioxidant defense mechanisms are crucial for plants to survive under stress conditions. We investigated the capacity of a wild fern species, Nephrolepis biserrata, growing in the vicinity of industrial land to accumulate heavy metals, and assessed its antioxidative response under metal stress. The...
