This study was carried out on the digestive gland on monthly samples coming from stations located near the industrial outfall of Morocco-phosphor III and IV factories, at Jorf-Lasfar and on samples made at reference station, as well as in digestive gland mussels experimentally contaminated with cadmium chlorate. At the same time, measurements of cadmium content in the tissues of the digestive gland were carried out, and, in sea-water, main spatio-temporal fluctuations of temperature and pH were analysed. Amylase activity showed seasonal variations with a maximum in summer-autumn period at the reference station. Amylase activity decreased in mussels coming from polluted stations and seemed to be inversely proportional to cadmium accumulation in tissues, particularly in winter. Similar, results obtained from experimental mussels showed that this activity decreased when concentration and duration of exposure to Cd increased.","AbstractOtherLang":"La variation de l'activité de l'alpha-amylase a été étudiée en fonction du degré de pollution métallique chez <i>Mytilus galloprovincialis</i>. Cette étude a été faite au niveau de la glande digestive des moules de taille 30-40 mm, d'une part, à partir des prélèvements mensuels provenant des stations avoisinant les rejets industriels de l'usine Maroc-phosphore III et IV dans la région de Jorf-Lasfar et d'autre part, sur des moules contaminées au laboratoire par du chlorure de cadmium. Parallèlement, nous avons réalisé le dosage du cadmium au niveau de ces mêmes glandes et effectué la mesure des paramètres physico-chimiques de l'eau de mer des différentes stations étudiées. La mesure de la température et du pH révèle une eau réchauffée et acide surtout au niveau de la station 53 située au voisinage immédiat du rejet principal. L'étude comparative de l'activité amylasique montre une variation saisonnière avec un maximum en été - automne. Si on considère les stations les plus proches de la source de pollution, cette activité présente une baisse significative par rapport à celle des animaux provenant des sites non ou peu pollués. Cette baisse est d'autant plus grande que l'accumulation du cadmium dans les mêmes conditions est plus importante, particulièrement en hiver. D'autre part, les résultats obtenus à partir des moules traitées au laboratoire montrent que l'activité de cette enzyme diminue lorsque la concentration et la durée d'exposition au cadmium augmentent.","BibLvlCode":"AS","StandardTitle":"Effet du cadmium sur l'activité de l'alpha-amylase chez <i>Mytilus galloprovincialis</i> = Effect of cadmium on alpha-amylase activity in <i>Mytilus galloprovincialis</i>","OrigTitleLangCode":"fr","OrigTitleLangCodeExtended":"fre","OrigTitleLangID":22,"DateLastModified":{"date":"2024-12-10 01:33:17.368041","timezone_type":1,"timezone":"+01:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":1998,"MonPub":null,"DateUpdate":"2001-04-03","DateCreate":"2001-03-27","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":0},"refs":null,"anarec":{"AnaID":7125,"PubliDate":1998,"Pagination":"51-61","XtraPublOfAnaID":null,"ISBN":null,"Volume":"8","Issue":"1-2","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43514,"SerRR":"Marine Life = Vie Marine.
