Increased tendency of relative fluorescence intensity (Ft/Fo value) at 300 μs and J step (2 ms) and a significantly (P < 0.05) increased Mo value (initial slope of fluorescence curve) were observed during 72 of diuron exposure in both species, whereas TBT did not increase those. These results strongly suggest that diuron efficiently blocked photosystem II-catalyzed photosynthetic electron transport at the secondary electron acceptor QB, which is original biological activity of diuron in diatoms. However, some parameters (e.g., φPo and φEo, Fv/Fo and PIABS,) were significantly (P < 0.05) decreased by TBT treatment. Although the mechanism responsible for the decrease is not clear, relatively severe reductions in levels of Fv/Fo (an indicator of water-splitting activity) by TBT treatment than diuron treatment suggest that TBT inhibits photosynthetic function via inhibition of photosynthetic oxygen evolving systems, a different mechanism than that of diuron. Moreover, present study suggested that PIABS derived from OJIP-test is a high sensitive biological marker for detecting the toxic effect of pollutants which inhibit photosynthetic function.","PeriodicalId":14585,"journal":{"name":"Japanese journal of environmental toxicology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85271811","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}

Fourto six-hour-old embryos after egg laying were obtained from the female’s brood chamber and immediately exposed to four or five level of different low-pH solutions for 120 hours. Embryonic toxicity was determined by evaluating inhibition of hatching and immobilization of the embryos following 72, 96, and 120 hours of exposure to low-pH solutions. Young(<24 hours following release from the female)and adults were also exposed to four or five level of different low-pH solutions for 48 hours. Low pH resulted in significant toxicity during embryonic development, as was indicated by inhibition of hatching and/or immobilization in embryos following exposure to pH 6.6 in soft water and to pH 6.0 in hard water. Immobilization was observed in young when subjected to solutions at/below pH 6.5 in soft water and at/below pH 5.2 in hard water. Adults were more tolerant to low pH in soft water than young or embryos, with the pH causing 50% immobilization in adults following 48-hour exposure 1.4 points lower than that which resulted in young or embryos 50% immobilization. The hardness of the water in low-pH solutions can influence the immobilization ratio of young. These observations suggest that the embryonic developmental test in early life stages allows for rapid and sensitive determination of low-pH toxicity.","PeriodicalId":14585,"journal":{"name":"Japanese journal of environmental toxicology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79047546","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}
