This Editorial introduces a series of papers on 'Progress in ecotoxicology, environmental chemistry and ecology' and was initiated in the context of the Joint SETAC GLB/GDCh Annual Meeting 2013 at the University of Duisburg-Essen. According to the title of the conference 'Ecotoxicology in an urban context' (Ökotoxikologie im urbanen Raum), a couple of conference contributions dealing with the o...

An improved knowledge and understanding of the fundamental biological requirements is needed for many of the species of fish held in captivity and, without this knowledge it is difficult to determine the optimal conditions for laboratory culture. The aim of this paper is to review the key issues concerning environmental enrichment for laboratory-held fish species and identify where improvements...

Analytical monitoring surveys routinely confirm that organisms in the environment are exposed to complex multi-component pharmaceutical mixtures. We are hence tasked with the challenge to take this into consideration when investigating the ecotoxicology of pharmaceuticals. This review first provides a brief overview of the fundamental approaches for mixture toxicity assessment, which is then fo...

The primary purpose of ecotoxicology is to provide a means of predicting the probability of harm from the use of chemicals or other environmental stressors (e.g., heat or suspended solids) upon complex natural systems. Although this statement may appear platitudinous, an examination of toxicological literature involving non-human species shows an inordinate preoccupation with studies of dose-re...

Due to the rapid advent in genomics technologies and attention to ecological risk assessment, the term "ecotoxicogenomics" has recently emerged to describe integration of omics studies (i.e., transcriptomics, proteomics, metabolomics, and epigenomics) into ecotoxicological fields. Ecotoxicogenomics is defined as study of an entire set of genes or proteins expression in ecological organisms to p...

Community ecotoxicology is defined as the study of the effects of contaminants on patterns of species abundance, diversity, community composition, and species interactions. Recent discoveries that species diversity is positively associated with ecosystem stability, recovery, and services have made a community-level perspective on ecotoxicology more important than ever. Community ecotoxicology m...

Gene expression is a unique way of characterizing how cells and organisms adapt to changes in the external environment. The measurements of gene expression levels upon exposure to a chemical can be used both to provide information about the mechanism of action of the toxicant and to form a sort of "genetic signature" for the identification of toxic products. The development of high-quality, com...
