Mesocosms Laboratory Experiments to Tackle China's "Green
Monster" Toxic Cyanobacterial Blooms

Four out of five of China's largest lakes as well as vast number of its smaller lakes
and reservoirs are under siege of rapidly proliferating toxic cyanobacterial blooms
(Picture 1); largely attributable to nitrogen and phosphorus over-enrichment
resulting from its accelerating urban, agricultural and industrial expansion.
Researchers from the Universities of NC-Chapel Hill, Texas, Northeastern, Wright,
and Tennessee, Knoxville, are working with Chinese collaborators at the Nanjing
Institute of Geography and Limnology Chinese Academy of Science, employing
outdoor mesocosms (Picture 2) in which nutrient manipulations (additions and
reductions) are conducted to determine which nutrients are controlling or "limiting"
blooms and to establish specific nutrient-bloom thresholds as a guideline for setting
nutrient reduction targets. They are also investigating cyanobacterial and
associated microbial community functional and compositional responses to these
manipulations, and the roles of sediments as "internal" stores of nutrients. This
work is supported by the US and Chinese National Science Foundations and the
Chinese Ministry of Science and Technology. For more information, please contact

Algal Indicators in Streams: A Review of their Application in Water
Quality Management of Nutrient Pollution

On June 27th, US EPA published a summary paper that describes the use of
algal indicators to develop water quality diagnostics for nutrient pollution in the
United States and reviews scientific developments in the application of algal
indicators across the world. Water quality managers can use this paper to better
understand when and how to utilize algae as indicators of nutrient pollution in
stream ecosystems.
