A dry-cleaning plant used carbon tetrachloride (CCl4) as a cleaning solvent until it was shut down because CCl4 was found to cause cancer and had been leaking into the groundwater. The plant owner offered to switch to liquified carbon dioxide instead and was allowed to reopen. Within 6 months cancer cases returned to normal. Explain whether the use of liquified carbon dioxide is a long term, safer environmental alternative to CCl4.
