An in situ assay with the microalga Phaeodactylum tricornutum for sediment-overlying water toxicity evaluations in estuaries.

abstract：:The rapid development of new technologies such as transcriptomics, proteomics, and metabolomics (Omics) are changing the way ecotoxicology is practiced. The data deluge has begun with genomes of over 65 different aquatic species that are currently being sequenced, and many times that number with at least some level of...
