Environmental Engineering Research (EER) is published quarterly by the Korean Society of Environmental Engineers (KSEE). EER covers a wide range of scientific and technological aspects of air, soil, and water management, with a particular emphasis on scientific and engineering solutions to environmental issues encountered during industrialization and urbanization. The journal focuses on interdisciplinary topics related to environmental pollution and its multi-regional/global impacts, including ecosystems and human health, as well as the scientific and engineering aspects of new technologies. The scope of the journal includes, but is not limited to, the following areas: 1. Atmospheric Environment and Climate Change: Global and local climate change, greenhouse gas control, and air quality modeling; 2. Renewable Energy and Waste Management: Energy recovery from waste, incineration, landfilling, and green energy; 3. Environmental Biotechnology and Ecology: Nanobiosensors, environmental genomics, bioenergy, and ecological engineering; 4. Physicochemical Technologies: Membrane technologies and advanced oxidation; 5. Environmental Systems Engineering: Desalination, Instrumentation, Control, and Automation (ICA), and reclaimed water reuse; 6. Environmental Health and Toxicology: Micropollutants, hazardous substances, ecotoxicity, and environmental risk assessment.
