The aquatic environment is known as an important sink for PFAS resulting in high concentrations in aquatic organisms. However  little is known about the developmental windows of sensitivity in which the PFAS chemicals are biologically active  in addition to the toxicity endpoints that best reflect chemical hazard. In this study  zebrafish Danio rerio were exposed to a 0.33% DMSO vehicle control  1uM chlorpyrifos CAS 2921 88 2 positive control  and eight concentrations 0 100 uM  half log dilutions of three environmentally relevant PFAS compounds in concentration response: PFOS CAS 1763 21 1  PFOA CAS 45285 51 6  and PFHxS CAS 355 46 4. There was also a group of unexposed zebrafish aliquoted from a single pool into all exposure plates to serve as a quality assurance measure. The goal of this study was to generate transcriptomic point of departure tPOD; a benchmark dose/concentration  based treatment level below which a concerted gene expression response is not observed estimates for zebrafish exposed to PFAS compounds as a health protective exposure level for risk assessment.

The aquatic environment is known as an important sink for PFAS resulting in high concentrations in aquatic organisms. However  little is known about the developmental windows of sensitivity in which the PFAS chemicals are biologically active  in addition to the toxicity endpoints that best reflect chemical hazard. In this study  zebrafish Danio rerio were exposed to a 0.33% DMSO vehicle control  1uM chlorpyrifos CAS 2921 88 2 positive control  and eight concentrations 0 100 uM  half log dilutions of three environmentally relevant PFAS compounds in concentration response: PFOS CAS 1763 21 1  PFOA CAS 45285 51 6  and PFHxS CAS 355 46 4. There was also a group of unexposed zebrafish aliquoted from a single pool into all exposure plates to serve as a quality assurance measure. The goal of this study was to generate transcriptomic point of departure tPOD; a benchmark dose/concentration  based treatment level below which a concerted gene expression response is not observed estimates for zebrafish exposed to PFAS compounds as a health protective exposure level for risk assessment.

The aquatic environment is known as an important sink for PFAS resulting in high concentrations in aquatic organisms. However  little is known about the developmental windows of sensitivity in which the PFAS chemicals are biologically active  in addition to the toxicity endpoints that best reflect chemical hazard. In this study  zebrafish Danio rerio were exposed to a 0.33% DMSO vehicle control  1uM chlorpyrifos CAS 2921 88 2 positive control  and eight concentrations 0 100 uM  half log dilutions of three environmentally relevant PFAS compounds in concentration response: PFOS CAS 1763 21 1  PFOA CAS 45285 51 6  and PFHxS CAS 355 46 4. There was also a group of unexposed zebrafish aliquoted from a single pool into all exposure plates to serve as a quality assurance measure. The goal of this study was to generate transcriptomic point of departure tPOD; a benchmark dose/concentration  based treatment level below which a concerted gene expression response is not observed estimates for zebrafish exposed to PFAS compounds as a health protective exposure level for risk assessment.
