Moreover, hepatic vitellogenin, a precursor of yolk protein that is specific to females, were examined in male and female Java-medaka collected in the same area. 17B-estradiol and estrone concentrations were less than 6.1 ng/L and 127 ng/L, respectively. The highest 17B-estradiol equivalent activity, 284 ng/L, was detected by in vitro assay in Sungai Kuyoh, which was adjacent to a sewage plant. 17B-estradiol and estrone concentrations were not equal to their estrogenic potentials determined by in vitro assay implying the presence of other estrogenic chemicals in these waters. Hepatic vitellogenin concentrations of both male and female java-medaka were the same to laboratory-cultured individuals. Although relatively high estrogen concentrations were detected in some waters of Malaysia, these were not high enough to induce hepatic vitellogenin in male fishes. Further research, however, is necessary to cover more number of sampling sites.","PeriodicalId":14585,"journal":{"name":"Japanese journal of environmental toxicology","volume":"12 1","pages":"141-147"},"PeriodicalIF":0.0,"publicationDate":"2006-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85081086","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}

The aim of the study was to evaluate experimentally the change in toxicity of oil when mixed with bioremediation agents and fertilizers used on oiled shores to enhance oil biodegradation under actual environmental conditions prevailing at the oiled site before considering any large-scale application. The protocols were designed to use three marine species at different trophic levels, i.e. diatoms Skeletonema costatum, rotifers Brachionus plicatilis, and red sea bream Pagrus major, and to carry out algal growth inhibition, zooplankton acute immobilization, and fish acute toxicity tests. The agents tested are: Inipol EAP22, oleophilic fertilizer; Terrazyme, bioaugmentation agent; and Super IB/Linstar, slow-release fertilizer. While Super IB/Linstar did not enhance the toxicity of oil, clear suppression of diatom cell growth was observed when 100 ppm of Inipol EAP22 was added to oil.
