“…The reciprocal changes in the cellular and collagen fractions in the hearts of WSF of dilbit-exposed sockeye suggest that xenobiotics can also act as a remodeling stimulus in the teleost compact myocardium. These changes may be driven by a WSF of dilbit-induced reduction in blood oxygen carrying capacity [34][35][36], impaired cardiac function [11,16,[37][38][39], and/or a direct PAH-induced transcriptional response in pathways regulating cell growth, proliferation, and structure [27,37,40]. Of particular interest are the concentrationdependent responses that were opposite in sockeye exposed to either 3.5 mg/L or 66.7 mg/L total PAH in WSF of dilbit.…”

Diluted bitumen (dilbit; the product of oil sands extraction) is transported through freshwater ecosystems critical to Pacific salmon. This is concerning, because crude oil disrupts cardiac development, morphology, and function in embryonic fish, and cardiac impairment in salmon can have major consequences on migratory success and fitness. The sensitivity of early life-stage salmon to dilbit and its specific cardiotoxic effects are unknown. Sockeye salmon parr were exposed to environmentally relevant concentrations of the water-soluble fraction (WSF) of dilbit for 1 wk and 4 wk, followed by an examination of molecular, morphological, and organismal endpoints related to cardiotoxicity. We show that parr are sensitive to WSF of dilbit, with total polycyclic aromatic hydrocarbon (PAH) concentrations of 3.5 µg/L sufficient to induce a liver biomarker of PAH exposure, and total PAH of 16.4 µg/L and 66.7 µg/L inducing PAH biomarkers in the heart. Furthermore, WSF of dilbit induces concentration-dependent cardiac remodeling coincident with performance effects: fish exposed to 66.7 µg/L total PAH have relatively fewer myocytes and more collagen in the compact myocardium and impaired swimming performance at 4 wk, whereas the opposite changes occur in fish exposed to 3.5 µg/L total PAH. The results demonstrate cardiac sensitivity to dilbit exposure that could directly impact sockeye migratory success. Environ Toxicol Chem 2017;36:354-360. © 2016 SETAC.

“…Monitoring of water objects is the collection, processing and delivery of information obtained for the purpose of regular monitoring of hydrological, hydrogeological, hydrogeochemical, sanitary-chemical, microbiological, parasitological, radiological and Toxicological indicators of timely revealing of negative processes, assessment and prediction of waste system recommendations on prevention and elimination of the adverse effects of the proposed action on water resources management. Various types of monitoring of water bodies are considered in [1,2,3,4,5,6], the negative impact of human activity on the state of the Caspian Sea was studied in [7,8,9,10,11,12], in the article [5] recommendations for improving environmental monitoring at the interstate level are proposed. This indicates the relevance of further study of the legal regulation of the ecological state of the Caspian Sea.…”

Information obtained as a result of monitoring of water bodies is taken as a basis for legal regulation of economic activities related to environmental pollution. In the context of a globalized economy, the strengthening of environmental protection measures in one of the neighboring countries often leads to the fact that the next plant will be built across the border, and its impact on the environment on a global scale will be the same. In this study, the authors studied the problem of finding new ways to solve the environmental problems of the Caspian Sea. The Caspian Sea belongs to Kazakhstan, the Russian Federation, Turkmenistan, Azerbaijan and Iran. to solve the environmental problems of the Caspian Sea, it is necessary to unify the environmental legislation of these countries, similar to the unification of the environmental legislation of the European Union countries.

“…Water soluble fractions of crude oil are a complex and toxic mixture of hydrocarbons that aquatic organisms directly encounter in oil spills. It plays an important role in the toxicity of crude oil to aquatic organisms (Lari et al, 2015). The fractions of oil that are most bioavailable to marine biota such as teleosts are the dissolved hydrocarbons, which include the polycyclic aromatic hydrocarbons (PAHs).…”
