Other claims from this paper (11)
- Observation Arsenic accumulated mainly in shoots.
- Observation Chromium accumulated mainly in roots.
- Intervention effect Chromium treatment significantly changed fresh weight, dry weight, relative water content, and plant height.
- Intervention effect Arsenic treatment did not significantly change the measured physical characters.
- Intervention effect Chromium accumulation caused dehydration of leaves.
- Intervention effect Chromium accumulation caused collapse of internal leaf structure.
- Intervention effect Chromium accumulation caused cellular breakdown of roots.
- Intervention effect Arsenic-treated ferns showed no significant structural changes in leaves, stems, and roots relative to controls.
- Intervention effect Clotted deposits occurred in roots and stems at the highest chromium concentration compared with controls.
- Intervention effect Clotted deposits occurred in roots and stems at the highest arsenic concentration compared with controls.
- Mechanism The authors interpret the absence of structural change as evidence that brake fern can take up, translocate and sequester arsenic.
