| Los bioensayos con microalgas como bioindicadores de ecotoxicidad son útiles para evaluar el impacto ambiental provocado por las descargas de productos químicos y el vertido de efluentes. Siendo el fitoplancton el primer eslabón de la cadena trófica en los ecosistemas acuáticos, cualquier alteración de la composición de la comunidad microalgal, producto de estrés toxicológico, modifica la estructura y la función de todo el sistema. El Río Chubut, en Argentina, abastece de agua a varias localidades; se utiliza para el riego de superficies cultivadas y la generación de energía eléctrica. Su curso puede recibir filtraciones, impactando en la calidad higiénico-sanitaria de sus aguas. En el Valle Inferior del río Chubut (VIRCH) se utilizan diversos pesticidas... |

| 1 The waste waters of the sugar industry, have constituted the main organic focuses of pollution of the Cuban coastal waters, during the years 1958 to 1991 worked around 160 sugar mill factories with a production average between 3,5 and 8,0 million metric ton sugar cane. During the last years this industry sensibly diminished its activity being considered the production of residual in 70 %, only working 25 % of the factories installed in Cuba, implying certain reduction of the sea impact. This report tries to interpret by means of toxicity bioassays the effects of waste waters of this industry on the survival of the spiny lobster Panulirus argus. Being that the values of LC50 were of 6,7; 5,6; 3,2 and 2,7 % for 24, 48, 72 and 96 h to the contact of... |

| Many organic and in organic contaminants originated from human activities are deposited and concentrated in aquatic sediments. The purpose of this review article is to analyze and discuss, the objectives, procedures and applications of bioassays on the triad of marine sediments, aiming at a reflection on the possibility of implementing regulations on the environmental monitoring of these studies in our country, so as to improve the environmental quality and its management on coastal zones. The main objective is to highlight the understanding of the adequate application and interpretation of bioassays. A summary of reports is presented, knowledge and analysis concerning marine sediments including, the chemical analysis, the direct determination of... |
