Hg and Se were present in all eggs analysed, but Cd was not detected. Hg was usually highest in booby eggs, and there was a southeast-to-northeast trend toward higher concetrations in this species; booby eggs from Midway contained the highest mean concentration of Hg (0·36 μg g⁻¹, wet weight). Se consistently occurred at lowest concentrations in booby eggs. When Se and Hg concentrations were expressed as nanomoles per gram, Se constituted 94–96% of the combined total at each location for shearwater and tern eggs. In booby eggs, the proportion as Se declined significantly (<em>α</em> = 0·05) from Oahu (93·4%) westward to Midway (85·9%). Although DDT occurred in most of the shearwater eggs from each site, it was not found in booby or tern eggs. DDE occured in all eggs, but mean concentrations did not exceed 0·6 μg g⁻¹. DDE concentrations were higher in eggs from the two south-eastern nesting sites and were consistently highest in shearwater eggs. PCBs were found in most of the shearwater and booby eggs, but were not detected in tern eggs. Other organochlorines usually occurred more frequently in eggs of shearwaters than in other species. The only exception were α-HCH and HCB, which occurred more frequently in booby eggs. Kepone, heptachlor epoxide, chlordane compounds, and toxaphene were not detected. Differences in residue concentrations seem to reflect differences in diets and seasonal movements of the birds, and perhaps other factors such as atmospheric and oceanic transport of chemicals and physiological differences among the species.</p></div>","PeriodicalId":100484,"journal":{"name":"Environmental Pollution Series B, Chemical and Physical","volume":"11 3","pages":"Pages 169-191"},"PeriodicalIF":0.0,"publicationDate":"1986-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/0143-148X(86)90022-4","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78382406","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}

When compared to a normally methylating control sediment, no significant differences were found in pH, E_h, microbial counts and methylating potential, but sulphide concentrations in Berry's Creek sediment were found to be unusually high. A causal connection between the elevated sulphide levels and low Hg methylation activity was established. In its current state, the contaminant poses little danger to biota, but a significant decline in sediment sulphide would be expected to increase the methylation and the biohazard of Hg.
