Acid lake samples (Dunas Lake) were collected during 19 months, and assessed with following treatments: water at local pH (±3.0) and samples with modified pH to 3.5, 3.8, 4.0, 4.3, 4.6, 5.0, 5.5, 6.0, and 6.5. Culture water samples with pH reduced to 3.0 were also assessed. Newborn P. reticulata were exposed during 96 h, and dead/immobile organisms were counted at various time intervals during exposure (short intervals in the beginning and long towards the end). Mean results of LT50 and confi­dence intervals from the Dunas Lake and control water with reduced pH were 1.36 (±0.48) h, and 1.03 (±0.50) h, respectively, with no statistical difference. Samples with increased pH showed a significant reduction in tox­icity, with no tox­icity detected at pH 6.0 and higher. Relationship between pH and lethal tox­icity for fingerlings of P. reticulata demonstrated that pH exerted a strong effect on the survival of this species at the Dunas Lake, explaining about 80% of the tox­icity observed.Submitted by JURANDI DE SOUZA SILVA (jssufba@hotmail.com) on 2012-06-01T14:30:31Z No. of bitstreams: 1 __onlinelibrary.wiley.co...4e8d12501ad7f56c6a402f78d6dbb.pdf: 217336 bytes, checksum: f496bda54deb2d83ceb3ae8136b0db77 (MD5)Made available in DSpace on 2012-06-01T14:30:31Z (GMT).
