Low concentrations of all the 3 chemicals had a stimulating effect. At a certain concentration of each chemical, an inhibitory effect became apparent in both assimilation and dark fixation tests. At higher concentrations the inhibitory effect was total in the assimilation, but the dark fixation values did not decrease zero. There was no clear differences in the susceptibility of vernal, early summer and late summer phytoplankton communities to the toxicants, except that the vernal phytoplankton community seemed to be less susceptible to ionic copper than the other communities. This may depend on differences in the species composition between the vernal and summer communities.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Effects of toxicants on brackish-water phytoplankton assimilation","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"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":1972,"MonPub":null,"DateUpdate":"2015-12-23","DateCreate":"2009-06-23","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":0},"refs":null,"anarec":{"AnaID":138278,"PubliDate":1972,"Pagination":"1-19","XtraPublOfAnaID":null,"ISBN":null,"Volume":"55","Issue":null,"BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":121814,"SerRR":"Commentationes Biologicae.
