Acute Toxicity of Pyrithione Photodegradation Products to Some Marine Organisms
We evaluated the acute toxicity of zinc pyrithione and copper pyrithione, used as antifouling booster biocides, and their six main photodegradation products to three marine organisms, representing three trophic levels: an alga (Skeletonema costatum), a crustacean (Tigriopus japonicus), and a fish (Pagrus major). The acute toxicity values of the pyrithiones for S. costatum, T. japonicus, and P. ...
متن کاملAcute and chronic toxicities of zinc pyrithione alone and in combination with copper to the marine copepod Tigriopus japonicus.
Zinc pyrithione (ZnPT) is a widely used booster biocide in combination with copper (Cu) in antifouling paints as a substitute for tributyltin. The co-occurrence of ZnPT and Cu in coastal marine environments is therefore very common, and may pose a higher risk to marine organisms if they can result in synergistic toxicity. This study comprehensively investigated the combined toxicity of ZnPT and...
متن کاملA novel bioassay for evaluating the efficacy of biocides to inhibit settling and early establishment of marine biofilms.
This paper presents a novel assay that allows a quick and robust assessment of the effects of biocides on the initial settling and establishment of marine photoautotrophic biofilms including the multitude of indigenous fouling organisms. Briefly, biofilms are established in the field, sampled, comminuted and re-settled on clean surfaces, after 72h chlorophyll a is measured as an integrating end...
متن کاملThe comparison of acute toxicity rate of Zinc and Copper sulfate on Caspian beluga
In the present study histological effects of copper and Zinc sulphate on, 250 Caspian beluga (Huso huso) fingerlings were studied. In this regard, fish of treatment groups were exposed to 0.1, 0.2, 0.4, 0.6, 0.7 and 0.8 mg/l of copper and 5, 25, 50, 75, 80 and 85 mg/l of Zinc sulphate during 4 days respectively. Behaviours and clinical signs of fish were recorded during the experiment. Samples ...
متن کاملP-41: Investigation of Correlation be tween Zinc, Copper and Iron Concentrations in Blood Serum, Testicular Tissue and Epididymal Tissue of Rams and their Associations with Serum Luteinizing Hormone Concentration
Background Correlation between metals may be useful in predicting toxicity to various biologically important organisms. The purpose of the current analysis was to evaluate the association of levels zinc, copper and iron in the ram blood serum, testicular tissue and epididymal tissue, and correlations of these elements to luteinizing hormone were investigated. MaterialsAndMethods Testis and bloo...
