The Environmental Engineering Research (EER) is published quarterly by the Korean Society of Environmental Engineers (KSEE). The EER covers a broad spectrum of the science and technology of air, soil, and water management while emphasizing scientific and engineering solutions to environmental issues encountered in industrialization and urbanization. Particularly, interdisciplinary topics and multi-regional/global impacts (including eco-system and human health) of environmental pollution as well as scientific and engineering aspects of novel technologies are considered favorably. The scope of the Journal includes the following areas, but is not limited to: 1. Atmospheric Environment & Climate Change: Global and local climate change, greenhouse gas control, and air quality modeling. 2. Renewable Energy & Waste Management: Energy recovery from waste, incineration, landfill, and green energy. 3. Environmental Biotechnology & Ecology: Nano-biosensor, environmental genomics, bioenergy, and environmental eco-engineering. 4. Physical & Chemical Technology: Membrane technology and advanced oxidation. 5. Environmental System Engineering: Seawater desalination, ICA (instrument, control, and automation), and water reuse. 6. Environmental Health & Toxicology: Micropollutants, hazardous materials, ecotoxicity, and environmental risk assessment.
