Chapter1: General characteristic of impacted polar ecosystems -- Chapter2: Theoretical bases of geoecological risk assessment in technogenic conditions -- Chapter3: Geoecological risks in the gas industry -- Chapter4: Risk of human exposure to chemical substances in gas industry -- Chapter5: Geological risk management in Gazprom Dobycha Yamburg -- Chapter6: Biogeochemical technologies of remediation and diagnosis of contaminated soils of impacted polar ecosystems -- Chapter7: Biogeochemical technologies of recultivation of disturbed soils of impacted polar ecosystems -- Chapter8: Testing of nature-like biogeochemical technologies for recultivation of disturbed and polluted soils of impacted arctic ecosystem in the face of increasing continentality of climate.This monograph is devoted to full-scale geoecological risk assessment in gas industry impacted polar areas and the relevant risk management options using innovative nature-like biogeochemical technologies. Readers will discover more about geoecological risks during gas production, transportation, storage and refining. Chapters discuss in detail the geodynamic dangers associated with designing and building of main gas pipelines. The book has interdisciplinary appeal, and specialists and practitioners in environmental sciences, ecology, biogeochemistry and those within the energy sector who are interested in understanding ecosystems affected by anthropogenic impacts in severe climatic conditions will find it particularly engaging. Through this book, readers will learn more about recultivation of contaminated soils as well as health risk assessments of chemical substances associated with the gas industry. .
