Study of Eutrophication and Aquatic Plants Growths in Selected Lakes and Rivers of Puerto Rico

摘要

This study was conducted to identify the physical and chemical parameters which promote eutrophication and aquatic plants growths in the lakes of Puerto Rico. Five lakes were considered, all of them man-made reservoirs. The results showed that lakes with visible states of eutrophy had a cation ratio between 0.74 and 1.45, whereas those with no visible state of eutrophy had a cation ratio of 0.15-0.35. Nutrient enrichment was present in the eutrophic lakes, and all the sediments were enriched with nitrogen and phosphorus. The nitrogen was present in the organic form rather than as ammonia compounds.
