ECOTOX, new questions for terrestrial and aquatic ecotoxicology

Aquatic and terrestrial mesocosms in amphibian ecotoxicology

Abstract. Aquatic and terrestrial mesocosms have been used successfully to examine ecological and ecotoxicological questions with amphibians. Mesocosms represent a bridge between the laboratory and the natural world, and allow for experimental research on factors that influence amphibian populations and communities. In this manuscript, we review the current literature utilizing mesocosms for ec...

Guidance Document on Aquatic Ecotoxicology

Ecotoxicogenomics: the challenge of integrating genomics into aquatic and terrestrial ecotoxicology.

Rapid progress in the field of genomics (the study of how an individual's entire genetic make-up, the genome, translates into biological functions) is beginning to provide tools that may assist our understanding of how chemicals can impact on human and ecosystem health. In many ways, if scientific and regulatory efforts in the 20th century have sought to establish which chemicals cause damage t...

AMEG: the new SETAC advisory group on aquatic macrophyte ecotoxicology

INTRODUCTION AND BACKGROUND Primary producers play critical structural and functional roles in aquatic ecosystems; therefore, it is imperative that the potential risks of toxicants to aquatic plants are adequately assessed in the risk assessment of chemicals. The standard required macrophyte test species is the floating (non-sediment-rooted) duckweed Lemna spp. This macrophyte species might not...

Toxicology and ecotoxicology of persistent organic microcontaminants in aquatic systems.

Persistent organic pollutants (POP) are a heterogeneous group of chemicals widely distributed in the aquatic environment. Some classes cause adverse effects in the biota at minute concentrations, persist in the environment for a long time, and bioaccumulate in animal tissues. Several strategies exist today to monitor their levels and evaluate their effects in the environment. Particularly, some...
