Hydra toxicity and protection by montmorillonite clay and APMs at the 0.1% inclusion level against 40 ppm PCB 77(A), 30 ppm PCB 126 (B), and 30 ppm PCB 153 (C). Hydra media and toxin controls are included for comparison. APM sorbents completely protect (100%) against PCB 77. APM sorbents also protect against PCB 126 and 153. The protection percentages for PCB 126 and 153 at the endpoint are as follows: (B) APM-12N: 100%, APM-18N: 90%. (C) APM-12N: 33%, APM-18N: 50%. (* p ≤ 0.05, ** p ≤ 0.01).
