We used flow cytometry to quantify the phagocytosis of fluorescent microspheres by hemocytes exposed in vitro to increasing levels of various metal compounds (AgNO<sub>3</sub>, CdCl<sub>2</sub>, CH<sub>3</sub>HgCl, HgCl<sub>2</sub> and ZnCl<sub>2</sub>). In some species, low doses of mercury (organic and inorganic) and Zn suggest a hormesis-like stimulation of phagocytic activity. At higher levels of exposure, all metals tested induced a significant dose-related inhibition of hemocyte phagocytosis. The species-specific sensitivity of the assay was determined by comparing the in vitro exposure using the metal concentration inducing a 50% suppression (EC<sub>50</sub>) of the phagocytic activity. Different species expressed different levels of sensitivity. Our results show the variability of the toxic response of different species within a group of similar organisms. It also highlights the need to consider species-species differences in ecotoxicological risk assessment.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Phagocytic activity of marine and freshwater bivalves: in vitro exposure of hemocytes to metals (Ag, Cd, Hg and Zn)","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":"Hemocyte; Phagocytosis; Cytometry; Bivalve; Metals","Notes":null,"AnaPub":2002,"MonPub":null,"DateUpdate":"2003-03-18","DateCreate":"2003-03-18","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000176053900006","VABBcode":null,"OpenAcc":0},"refs":null,"anarec":{"AnaID":33248,"PubliDate":2002,"Pagination":"189-200","XtraPublOfAnaID":null,"ISBN":null,"Volume":"58","Issue":"3-4","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":42203,"SerRR":"Aquatic Toxicology.
