Your post seems to off topic to the query, but I will answer it.
I don't believe that chlorine gas is the preferred method for control of zebra mussels as you suggest.
Personnel exposure concerns, insurance requirements, community safety issues and regulations have caused the majority of utilities to eliminate chlorine gas in ton cylinders and replace the gas with sodium hypochlorite bleach even though bleach is roughly 3 times the cost.
The ability of the Alkylbenzyldimethylammonium chlorides to control zebra mussels using only short exposures gives rise to a number of advantages over chlorine. These include:
[ul]
[li]Less chemicals released to the environment.[/li]
[li]Product concentrations can be monitored and verified during the entire application.[/li]
[li]Permanent installation of tankage, dikes, and feed equipment is generally not required.[/li]
[li]Reduced impact on entrained plankton.[/li]
[li]Costs are lower since far less chemical is required.[/li]
[/ul]
In general, I prefer to reference sources of factual information rather than just throwing out opinions. The reader is capable of reviewing the information and developing their own conclusions.
I am just a messenger. If you disagree with the papers, I suggest you contact the University of West Virginia and/or GE. I doubt that either of these organizations are selling Alkylbenzyldimethylammonium chlorides.
