На основе данных о содержании Fe, Zn, Cu, Cd, Ni в бурых водорослях-макрофитах Sargassum pallidum, S. miyabei и Stephanocystis crassipes как аккумулирующих биоиндикаторах, собранных в июле 2017 г. вдоль побережья Уссурийского залива, получено представление о состоянии прибрежных вод этого залива. Установлено, что найденные концентрации тяжелых металлов на большинстве станций находятся в пределах фонового диапазона для исследуемых видов в северо-западной части Японского моря. Показано также, что существенное превышение фона некоторых металлов, прежде всего Fe и Cu, наблюдается в водорослях импактных районов – мысов Геллера и Муравьиный в вершине залива, в бухтах Промежуточная и Десантная в городской зоне Владивостока. Based on the data on the content of Fe, Zn, Cu, Cd, and Ni in macrophyte brown algae Sargassum pallidum, S. miyabei, and Stephanocystis crassipes, as accumulating bioindicators collected in July 2017 along the coast of the Ussuri Bay, an impression on the conditions of the coastal waters of the Bay was gained. It was established that the concentrations of heavy metals at most stations are within the background range for the species under study in the northwestern part of the Sea of Japan. It was also shown that a significant excess of the background of some metals, primarily Fe and Cu, is observed in the algae of the impact areas – Geller Cape and Muravyiny Cape at the top of the Bay, in the Promezhutochnaya Bay and Desantnaya Bay in the urban zone of Vladivostok.

The Impact

As an external appendage, hair is exposed to multiple stresses of different origins such as particles and gases in air, or heavy metals and chemicals in water. So far, little research has addressed the impact of water pollution on hair. The present study describes a new ex vivo model that allowed us to document the adverse effects of water pollutants on the structure of hair proteins, as well as the protective potential of active cosmetic ingredients derived from a biomimetic exopolysaccharide (EPS). The impact of water pollution was evaluated on hair from a Caucasian donor repeatedly immersed in heavy metal-containing water. Heavy metal retention in and on hair was then quantified using Inductively Coupled Plasma Spectrometry (ICP/MS). The adverse effects of heavy metals on the internal structure of hair and its prevention by the EPS were assessed through measurement of keratin birefringence. Notably, the method allows the monitoring of the organization of keratin fibers and therefore the initial change on it in order to modulate the global damage in the hair. Results revealed an increasing amount of lead, cadmium and copper, following multiple exposures to polluted water. In parallel, the structure of keratin was also altered with exposures. However, heavy metal-induced keratin fiber damage could be prevented in the presence of the tested EPS, avoiding more drastic hair problems, such as lack of shine, or decrease in strength, due to damage accumulation.

The paper contains the study of heavy metals in three species - Sargassum miyabei , Sargassum pallidum , Cystoseira crassipes in the coastal waters of the Posyet Bay. The analysis of the spatial distribution of trace elements revealed the highest contents of zinc, copper and nickel in the Troitsa Bight, due to recreational pressure and a high concentration of nickel and cadmium in Sivuchya Bight that was caused by transboundary atmospheric transport. All of detected concentrations exceed natural background values for the North-Western part of the Sea of Japan. The authors show that there has been a distinct change in the environmental situation in the the Posyet Bay since 1998: the concentration of lead has sharply decreased, the content of zinc, copper and cadmium has decreased, it could be connected with influence reduction in the free economic zone, located on the Chinese side on the Tumannaya River.

Определены концентрации ртути в талломах массовых видов водорослей-биоиндикаторов родов Ulva lactuca, Ulvaria splendens, Sargassum miyabei, Sargassum pallidum, из прибрежных вод вокруг г. Владивостока Японского моря за летний период 2020 г. Содержание Hg варьируется от 5,8 до 41,4 нг/г сухой массы. Наибольшая концентрация наблюдается в ульве, отобранной из района бывшего полигона ТБО «Горностай», где ранее отмечались повышенные концентрации Cu, Pb, Fe, Zn. Отмечена тенденция уменьшения концентраций ртути в водорослях с июня по июль, как для ульвы, так и для саргассума. Водоросли вокруг Владивостока содержат очень низкие концентрации ртути и не превышают ПДК промысловых водорослей – 500 нг/г сухой массы. Полученные концентрации соответствуют величине Q1 – 25 процентилю общемировой выборки для зеленых и в основном Q1 для бурых, что говорит об отсутствии загрязнения ртутью литоральной зоны вокруг г. Владивосток в исследуемый период. The concentrations of mercury in mass species of algae - bioindicators of the genera Ulva lactuca, Ulvaria splendens, Sargassum miyabei, Sargassum pallidum, from coastal waters around Vladivostok, the Sea of Japan in summer of 2020 were determined. The Hg concentrations varies from 5.8 to 41.4 ng / g dry weight. The highest concentration is observed in the Ulva, taken from the area of the former landfill "Gornostay", where previously there were increased concentrations of Cu, Pb, Fe, Zn in algae. A tendency of a decrease in mercury concentrations in algae from June to July was noted for both Ulva and Sargassum in connection of atmosphera precipitations decreasing. Algae around Vladivostok contained very low concentrations of mercury and did not exceed the MPC for commercial algae - 500 ng / g dry weight. The obtained concentrations correspond to the value of Q1 - the 25th percentile of the global sample for green algae and mainly Q1 for brown ones, which indicates the absence of mercury contamination of the littoral zone around Vladivostok during the study period.

The features of pollution of aquatic environments (river and lake) in the area of impact of Grodnenskoe polymetallic mine, located in the water basin of the lake Baikal (Republic of Buryatiya) is considered. The main existing sources of pollution, the degree of toxicity and the scale of the impact on the drainage watercourses, as well as the peculiarities of transportation of pollutants were determined. Existing spatial zones of ecological risk for aquatic landscapes associated with modern geochemical impact of Kholodninskoe mine were revealed. Today, it is a part of the Kholodnaya River basin, which flows near the mine and receives water streams from abandoned tunnels. In the waters of these streams very high concentrations of pollutants (a number of heavy metals) have been revealed. They are hundreds and thousands times higher than the maximum permissible concentration. After the confluence of streams with the Chpolodnaya River pollution zone have been formed, within which the concentration of zinc in the waters of the river exceeds the normative values. For the TyyaRiver, which drains the ore body, but does not receive streams from the tunnels, significant excess of standards for the heavy metals content have not been found. Directly in the water area of the Lake Baikal, including the Gulf of Angarskiy Sor, where the Kholodnaya River flows, significant excess of permissible values was not identified, either. Based on the analysis of the selected samples, Conclusions based on the selected samples analysishave been made on specific featuresof current chemical elements migration in the «Kholodnaya River – Lake Baikal» system at the present level of economic activity, as well as the prospects for the future.

The Impact

Four salt-water marinas were studied in an attempt to ascertain their impact on water quality. Analyses of water, sediment and biological samples showed no evidence of dissolved oxygen depletion or nutrient enrichment of the water column and no nutrient enrichment, organic pollution, toxic pollution or bacterial degradation of the sediments. Analyses of organotin compounds from antifouling residues were inconclusive due to problems in interpreting the results and comparing them with overseas results. The major impact was found to be the build-up of heavy metals (Pb, Cu, Zn, Hg) and petroleum hydrocarbons. The accumulated levels of these, however, were similar to those in other areas affected by human activity and were not indicative of significant water pollution. Nevertheless, water quality within marinas can be improved and guidelines for marina construction were developed based on the results of this study and a literature review.

This paper discusses the derivation of environmental quality standards for coastal waters and the difficulties of using such standards for controlling industrial discharges. Attention is focused on the common List II substances, copper, chromium, lead, nickel, zinc and arsenic - and their effects on marine life. The adequacy of existing toxicity data is discussed and it is concluded that long exposure tests are required to provide information on sublethal effects. Such data are currently limited. It is also important that consideration be given to the effects that reducing salinities and increasing temperatures have in increasing the toxicity of these substances. The complexity of interpreting the results of laboratory toxicity data to coastal waters is discussed with reference to a study of the impact of an industrial discharge.
