Toxicity of elevated partial pressures of carbon dioxide to invasive New Zealand mudsnails

0
The authors tested the efficacy of elevated partial pressures of CO2 to kill invasive New Zealand mudsnails. The New Zealand mudsnails were exposed to 100‐kPa at three water temperatures, and the survival was modeled versus dose as cumulative °C‐h. We estimated an LD50 of 59.4°C‐h for adult and juvenile New Zealand mudsnails. The results suggest that CO2 may be an effective and inexpensive lethal tool to treat substrates, tanks, or materials infested with New Zealand mudsnails. Environ. Toxicol. Chem. © 2012 SETAC
