| description | BACKGROUND, GOAL AND SCOPE: Cleaner CRYSTAL Simple Green (SG) was used for the cleanup of the oil spill in the Baltic Sea near Lithuania in 2001. No scientific data are available on the effects and consequences of its application for local aquatic life. The aim of this study was to determine and compare sublethal effects of a) solution SG; b) crude oil alone; c) SG in combination with oil on rainbow trout Oncorhynchus mykiss at different stages of its development in laboratory conditions.
Laboratory studies were performed on adult rainbow trout (4-day duration) and on yolk-sac larvae (25-day duration) evaluating their biological parameters. Concentrations of water-soluble and thin-dispersed fractions of petroleum hydrocarbons were measured using gas chromatography.
SG solution (0.5 mg/l) did not affect the survival of larvae and adult fish, and no significant changes were determined in respiratory parameters of the exposed lar vae and adult fish. The most expressed alterations were found in morphological parameters (a decrease in the average body mass) of larvae and in haematological indices (a decrease in the leukocyte count) of adult fish at the end of the tests. Crude oil (1610 mg/l) did not affect the survival of adult fish during the 4-day exposure. An increase in larvae mortality rate (approximately 36%) was recorded at the end of the tests. A significant decrease in the average body mass and heart rate of larvae as well as in gill ventilation frequency of larvae and adult fish were determined. SG combined with oil induced an increase in larval mortality approximately 46% of individuals died at the end of the tests. No mortality was recorded in adult fish. The average body mass and heart rate of larvae were significantly decreased. Marked changes were also found in respiratory parameters (gill ventilation frequency of larvae and adult fish significantly decreased, while 'coughing' rate increased). A 1-day, 2-day exposure of fish to SG combined with oil induced a significant decrease in the leukocyte count of adult fish, which was also determined at the end of the tests. The augmentation of adverse impact could be explained by the data obtained from our studies. When SG was added into dilution water with crude oil the concentration of petroleum hydrocarbons in the mixture increased 3 approximately 4.5 times after 24 h and 96 h, respectively.

To diminish the negative impact of oil spill cleanup using chemicals on aquatic ecosystems, it is recommended to carry out more comprehensive studies of their effects and after-effects in laboratory conditions using a wide scale of local aquatic organisms. The selected species of the most sensitive aquatic organisms should include those which are unable to escape the impact of combined action of oil and cleaners. Special attention should be directed to the research of effects of these pollutants on studied organisms at their most sensitive stages of life (reproduction, hatching, early stages of development), as after-effects of exposure to pollutants may be observed in future generations.</description><identifier>ISSN: 0944-1344</identifier><identifier>EISSN: 1614-7499</identifier><identifier>DOI: 10.1065/espr2005.04.245</identifier><identifier>PMID: 15986996</identifier><language>eng</language><publisher>Germany: Springer Nature B.V</publisher><subject>Adults ; Animals ; Aquaculture ; Aquatic ecosystems ; Aquatic life ; Aquatic organisms ; Body mass ; Comparative studies ; Crude oil ; Developmental stages ; Ecosystem ; Environmental cleanup ; Fish ; Fish oils ; Gas chromatography ; Hatching ; Heart Rate ; Hydrocarbons ; Laboratories ; Larva - growth & development ; Larvae ; Leukocytes ; Mortality ; Oil spills ; Oncorhynchus mykiss ; Oncorhynchus mykiss - physiology ; Petroleum ; Petroleum - toxicity ; Petroleum hydrocarbons ; Pollutants ; Respiration ; Salmon ; Sublethal effects ; Surface-Active Agents - toxicity ; Toxicity Tests ; Trout ; Ventilation ; Water Pollution - prevention & control ; Yolk</subject><ispartof>Environmental science and pollution research international, 2005-01, Vol.12 (3), p.136-139</ispartof><rights>Ecomed 2005</rights><lds50>peer_reviewed</lds50><woscitedreferencessubscribed>false</woscitedreferencessubscribed><citedby>FETCH-LOGICAL-c415t-500158ecb5c88e866e30bac4205c8ac07f517c90eacdb5f527fbe53a46b573483</citedby></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><link.rule.ids>314,780,784,27924,27925</link.rule.ids><backlink>$$Uhttps://www.ncbi.nlm.nih.gov/pubmed/15986996$$D View this record in MEDLINE/PubMed$$Hfree_for_read</backlink></links><search><creatorcontrib>Vosyliene, Milda Z</creatorcontrib><creatorcontrib>Kazlauskiene, Nijole</creatorcontrib><creatorcontrib>Joksas, Kestutis</creatorcontrib><title>Toxic effects of crude oil combined with oil cleaner simple green on yolk-sac larvae and adult rainbow trout Oncorhynchus mykiss</title><title>Environmental science and pollution research international</title><addtitle>Environ Sci Pollut Res Int</addtitle><description>BACKGROUND, GOAL AND SCOPE: Cleaner CRYSTAL Simple Green (SG) was used for the cleanup of the oil spill in the Baltic Sea near Lithuania in 2001.
