We examined toxin uptake and release in marine mussels for both particulate and dissolved phases of the hepatotoxin microcystin, produced by the freshwater cyanobacterial genus <i>Microcystis</i>. We also extended our experimental investigation of particulate toxin to include oysters (<i>Crassostrea</i> sp.) grown commercially for aquaculture. California mussels (<i>Mytilus californianus</i>) and oysters were exposed to <i>Microcystis</i> and microcystin toxin for 24 h at varying concentrations, and then were placed in constantly flowing seawater and sampled through time simulating riverine flushing events to the coastal ocean. Mussels exposed to particulate microcystin purged the toxin slowly, with toxin detectable for at least 8 weeks post-exposure and maximum toxin of 39.11 ng/g after exposure to 26.65 μg/L microcystins. Dissolved toxin was also taken up by California mussels, with maximum concentrations of 20.74 ng/g after exposure to 7.74 μg/L microcystin, but was purged more rapidly. Oysters also took up particulate toxin but purged it more quickly than mussels. Additionally, naturally occurring marine mussels collected from San Francisco Bay tested positive for high levels of microcystin toxin. These results suggest that ephemeral discharge of <i>Microcystis</i> or microcystin to estuaries and the coastal ocean accumulate in higher trophic levels for weeks to months following exposure.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Evidence of freshwater algal toxins in marine shellfish: Implications for human and aquatic health","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":"Microcystin","OtherDescriptors":null,"Notes":null,"AnaPub":2016,"MonPub":null,"DateUpdate":"2018-02-13","DateCreate":"2017-02-21","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000388780400006","VABBcode":null,"OpenAcc":1,"DOI":"10.1016/j.hal.2016.09.007"},"refs":null,"anarec":{"AnaID":283590,"PubliDate":2016,"Pagination":"59-66","XtraPublOfAnaID":null,"ISBN":null,"Volume":"59","Issue":null,"BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":45642,"SerRR":"Harmful Algae.
