Use of Early Life-Stages of Zebrafish to Assess Toxicity of Sediments Contaminated by Organotin Compounds

2016

ABSTRACTThis study examined the response of early life-stages (ELS) of zebrafish to organotin-contaminated sediment from Lake Huruslahti (HL) in Central Finland. A dilution series (0, 10, 33, and 100%) of the native (HL) and the sediment spiked with tributyltin (TBT) determined a dose-response of zebrafish ELS to organotin-contaminated sediment. Sediment elutriates were assessed by bacterial bioluminescence assay and microscopical pathologies of 1–3 days post-fertilization zebrafish (1–3dpfZF). Brain aromatase (cyp19a1b) and tissue vitellogenin (vtg1) were assayed from early-juvenile zebrafish (20dpfZF) exposed to intact sediment. In vivo modulation of cyp19a1b and vtg1 transcripts in 20dpf…
