Environmental Chemistry Letters is located at the interfaces of geology, chemistry, physics and biology. Articles are of high importance to the study of natural and engineered environments. Environmental Chemistry Letters publishes four-page articles of outstanding significance in the following fields Characterisation of natural and affected environments; Behaviour, prevention, treatment and control of mineral, organic and radioactive pollutants; Interfacial studies involving media such as soil, sediment, water, air, organism, and food; Green chemistry, environmentally friendly synthetic pathways, and alternative fuels; Ecotoxicology and risk assessment; Environmental processes and modelling; Environmental technologies, remediation and control; Environmental analytical chemistry, biomolecular tools and tracers e.g. stable isotopes
