Significant lethal effects were observed for all species studied, with mass mortalities occurring during the warmest months of the year. Of the seven species examined, the copepods identified as estuarine species had steeper mortality curves and higher upper lethal thermal limits than the more neritic forms. The estuarine species have apparently evolved the ability to live in subtropical areas under temperature conditions very close to their upper thermal limits. Coastal species, on the other hand, exhibit a greater variation in temperature sensitivity so thermal additions in subtropical estuaries could be very significant in limiting their distribution and abundance.</p></div>","PeriodicalId":100482,"journal":{"name":"Environmental Pollution (1970)","volume":"20 1","pages":"Pages 3-19"},"PeriodicalIF":0.0,"publicationDate":"1979-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/0013-9327(79)90049-1","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"52961566","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

They were the most toxic of 21 tested materials likely to be present in used well-drilling fluids. Least toxic were bentonite, barite, and several organics. Simulated ‘13-lb’ drilling fluid was lethal at 1·8% concentration, used fluids from the Mackenzie delta at 0·83, 4·2, and 5·3%.</p><p>There was no consistent picture for joint action in mixtures. Used fluids were lethal at 0·71, 1·2, and 0·83 times the values predicted from an assumption of additive toxicity of approximated components. Those results were in statistical agreement with additivity. The LC50 of the simulated fluid was 1·5 times the value predicted from its seven components, significantly less-than-additive. When the seven most toxic components were added singly to simulated fluid, about half the results were not different from additive joint action. However, for every component plus fluid, there was antagonism in at least one of three proportions tested. Strongest antagonism was 3·7 times the predicted value for the surfactant B-Free added to fluid. Decreased toxicity may have resulted from sorption of components on bentonite, or different toxic mechanisms for fish. Six of the seven most toxic components lost toxicity upon ageing for 16 days in water, while B-Free increased sharply in toxicity.</p></div>","PeriodicalId":100482,"journal":{"name":"Environmental Pollution (1970)","volume":"19 4","pages":"Pages 269-281"},"PeriodicalIF":0.0,"publicationDate":"1979-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/0013-9327(79)90119-8","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"52961946","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
