Toxic Effects of Crude Oil Combined with Oil Cleaner Simple Green on Yolk-sac Larvae and Adult Rainbow Trout Oncorhynchus mykiss (4 pp)

Abstract

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.

Toxicity of crude oil and fuel oil on the embryonic development of the Large Yellow Croaker (Larmichthys crocea)

“…In this study, we found the heartbeat become more slow and stop finally with the concentration oils, and the group of TJ014 were more serious than -20 (Table 1), The heart rate became slow significantly of rain trout (Oncorbyncbus mykiss) at the yolk-sac larvae stage when stressed by crude oil or crude oil combined with oil cleaner simper green [29], from studied with Prestige oil spill on the medaka, the abnormalities included pericardial edemas with accompanying tubular hearts, hemostasis and bradycardia [9]. Vertebral abnormality was familiar phenomena on the fish which lived in the oil spill waters, we found spinal curvatures was general in the embryonic development when eggs were exposed to oil pollution (Table 1), the incidence of vertebral abnormality in larval rainbowfish (Melanotaenia fluviatilis) exposed to water accommodated fractions for 96 hours as one-hour-old embryos were high when the TH concentration increased [26], the phenomena also found in the other pollutants like PBDEs and permethrin [19,10].…”

“…Previous studies have focused on all aspects of aquatic organisms stressed by oil and correlative production, for instance, the survival [11,6,26,4,17,16,29,27,15], morphological parameters like as a decrease in the average body mass, heart rate, gill ventilation frequency and time to hatch [29,9,15], hematological physiological parameters like as erythrocyte, leukocyte counts, haemoglobin concentration, haematocrit level, plasma osmolarity, plasma Na + and K + , plasma chloride concentration and cortisol [29,15,28], biochemical parameters like as glutathione-S-transferase, catalase, superoxide dismutase, glutathione reductase, selenium-dependent glutathione peroxidase, glutathione, glutathione disulfide, aspartate aminotransferase, gamma-glutamyl transferase, acyl-CoA oxidase, plasma glucose, ethoxyresorufin-O-deethylase and alanine transaminase activity [24,2,32,20,22,21,8,3,28], histological parameters like as the liver and gills [22,21,28] and molecular level changes like as micronucleus frequency, DNA repair, cytochrome P4501A, DNA adducts, DNA single strand breaks, microsatellite and AFLP loci [1,18,5,25,14].…”

Research Into the Effect of Heavy Metals and Their Binary Mixture on the Cardio-Respiratory System of Fish Larvae / Sunkiųjų Metalų Ir Jų Binarinio Mišinio Poveikio Žuvų Kardiorespiracinei Sistemai Ankstyvojoje Ontogenezėje Tyrimai

“…Toksikologiniams tyrimams dažniausiai pasirenkamos žuvys, kadangi jos yra geriausiai ištyrinėti vandens organizmai, be to, daugybė tyrimų rodo, kad žuvys ankstyvuoju vystymosi laikotarpiu yra labai jautrios teršalams Svecevičius et al 2003;Kazlauskienė et al 2004;Vosylienė et al 2005).…”

Genotoxicity and Immunotoxicity of Wastewater Effluents Discharged from Vilnius Wastewater Treatment Plant

“…Crude oil immunotoxicity, genotoxicity and cytotoxicity were reported in different fish species -rainbow trout (Oncorhynchus mykiss), Atlantic cod (Gadus morhua), turbot (Scophthalmus maximus), perch (Perca fluviatilis) etc. (Vosylienė et al 2005;Baršienė et al 2006a, b;Bolognesi et al 2006), and mussels . Increased genotoxicity and cytotoxicity induced by petroleum refinery effluents were shown in fish also (Çavaş & Ergene-Gözükara 2005).…”
