Giant Snails to Control Air Quality
Giant African land snail

Giant African land snails will control the level of air pollution in St. Petersburg.
      
      These snails (Achatina fulica) are currently employed at the waste water processing plant. Three of them are breathing fresh air, and the other three receive a mixture of air with the plants waste discharge.
      
      Researcher from St. Petersburg Research and Development Centre of Ecological Safety have built an automated system of controlling snails well being. Difference in health of snails from the two groups will indicate the level of air pollution.
      
      This is not the first example of using living organisms as bioindicators: crawfish tell St. Petersburg scientists about water quality on citys intake facilities.
