Aims of the journal are: discussion and exchange of ideas and information on complex environmental issues by significantly advancing our understanding of environmental hazards, processes, and impacts, and offer solutions to today's and future problems. Topics in the section "Source, transport and Fate" include: emerging contaminants; source characterisation; biotransformation; chemical/physical transformation; presence and activity of metabolites; soil and aquatic science; metal speciation; atmospheric science; and climate change. The section "Exposure and impacts" deal with topics like human and ecotoxicology; biological impact of nanoparticles in the environment; microbial resistance to antibiotics; environmental biology; endocrine disruption; environmental epigenetics; environmental and occupational health; food safety, environmental biotechnology, remediation. Topics in the section "Policy and legislation" include: quality assurance and control; legislative issues and guidelines; remediation; environmental data interpretation; environmental regulation. In "Novel Analytical Tools and Measurement Technologies" topics include recent developments in sampling technologies, neural networks, smart sensor technologies and signal capture and enhancement technologies. Others are multiplexed sensing, miniaturization technologies, intelligent packaging for continuous monitoring, novel materials with environmental applications and remediation processes. In the final section "Sustainable Solutions and Technologies " authors are encouraged to suggest how the effects of these contaminants can be negated or reduced by addressing alternative more sustainable or greener strategies at the sources of these contaminants by developing an alternative technology base that is inherently non-toxic to living things and the environment.
