Última Acute toxicity tests of a textile mill wastewater effluent and a "detergent wash" with a Hermit crab (Climbinarius Africanus) (Aurivillius) OceanDocs Ajao, E.A.. Bioassay tests were conducted with wastewater effluents from a textile mili and a detergent packing plant using the hermit crab. Clibinarius africanus. (Aurivillus) as experimental animal. LC50 values were evaluated using static testing procedures for 24, 48 and 96 hour. For the textile effluent, means of 79.0, 50.24 and 51.81 percentage effluent by volume were obtained in respect of crabs in the “medium” weight range (0.3 – 0.7grams) for the test periods. For the “detergent wash”, 95.16, 85.00 and 82.33 percentage effluent by volume represented means of values obtained for “small” size crabs (weight range 0.08–0.24 grams) and 96.0, and 81.50 percentage effluent by volume for ‘medium’ size crabs for 24, 48 and 96 hour respectively. Spearman’s Rank... Tipo: Report Palavras-chave: Pollutants; Water pollution; Pollutants; Water pollution; Http://aims.fao.org/aos/agrovoc/c_6076; Http://aims.fao.org/aos/agrovoc/c_8321. Ano: 1985 URL: http://hdl.handle.net/1834/2440 etude quantitative et qualitative des métallothioneines chez la daurade <"Sparus aurata"> exposée aux metaux lourds OceanDocs Jebali, J.; Ghedira, J.; Bouraoui, Z.; Ameur, S.; Gherbej, H.; Boussetta, H.. Dans l’environnement marin, les éléments traces peuvent s’accumuler dans les organismes à des concentrations supérieures à celles présentes dans l’eau. L’étude de la distribution tissulaire des métaux traces au niveau des organismes qui y sont exposés, constitue un aspect très important pour la compréhension de leur devenir. En outre, le suivi de la réponse biologique spécifique de ces organismes sentinelles aux xénobiotiques complète et consolide l’analyse chimique. Ce travail vise à étudier la distribution tissulaire des métaux traces et des métallothionéines (MTs) chez la daurade «Sparus aurata » traitée par un métal essentiel (le cuivre) et un métal non essentiel (le cadmium) à une concentration de 500µg /Kg de poids frais pendant 48 heures....

Ano: 2009 URL: http://hdl.handle.net/1834/3780 Determination of persistent organic pollutants in water of new Damietta harbour, Egypt OceanDocs Hamed, M.A.; Said, T.O.. Persistent organic pollutants (POPs) which include chlorinated pesticides and petroleum hydrocarbons were determined in water samples collected from Damietta Harbour during 2005. Concentration of total pesticides ranged from 0.02 to 0.07 ng/L and from 1.09 to 201.82 ng/L during winter and summer seasons, respectively. The increasing order of total pesticides was: THCHs < TC < total DDTs with concentrations ranged from 0.004-3.20 ng/L, 0.001-3.93 ng/L and 0.002-194.68 ng/L, respectively in the area of study. The average concentrations of total petroleum hydrocarbons were below the admissible environmental levels. They ranged from 2.17-72.89 µg/L and from 5.67-87.56 µg/L during January and July 2005, respectively. However, concentrations of PAHs were...
