Guide for Ecological Considerations for the Use of Oil Spill Dispersants in Freshwater and Other Inland Environments, Lakes and Large Water Bodies

Работа посвящена теме устранения загрязнения акватории морей нефтепродуктами в условиях сложной ледовой обстановки. Приведены различные способы очистки водных пространств от нефти и нефтепродуктов, дан сравнительный анализ их особенностей и недостатков. Описана проблема очистки водоемов от нефтепродуктов при наличии колотого и сплошного льда. Предложена новая технология использования сорбента в таких специфических условиях. Представлена сконструированная авторами установка, которая подключается к стандартным судовым системам и позволяет без их затратной модернизации эффективно бороться с нефтеразливами в низкотемпературных широтах. Ключевые слова: новая технология использования сорбента, арктический шельф, боновые заграждения, разлив нефти, диспергенты, сорбент, пульпа, струйный смеситель : This work is focused on the problem of eliminating the pollution of the seawater with oil products in difficult ice conditions. Various methods of cleaning water spaces areas from oil and oil products are presented, and a comparative analysis of their features and disadvantages is given. The problem of cleaning water bodies from oil products in the presence of crushed and solid ice is described. A new technology for using the sorbent in such specific conditions has been proposed. An installation designed by the authors is presented, which is connected to standard ship systems allows to effectively deal with oil spills in low-temperature latitudes with no need for high-cost modernization. Keywords: Arctic shelf, booms, oil spill, dispersants, sorbent, pulp, jet mixer

The risk of infestation of the population by the opisthorchiasis causative agent in the middle and lower reaches of the Iset River was estimated. Areas with the highest risk of peoples infection by Opisthorchis felineus’ metacercaria are identified. These territories are confined to the zones of removal of the opisthorchiasis causative agent, which are river beds and large water bodies that constantly connect with rivers. Steady risk of infection of the population is determined by the loimopotential of the opisthorchiasis natural focus. The general infestation of juveniles fishes in the middle and lower current of the Iset River made 9,9 %, annuals – 21,5 %, two-year-olds – 19,5 %.
