Comparing Ocular Toxicity of Legacy and Alternative Per- and Polyfluoroalkyl Substances in Zebrafish Larvae.

Studies comparing the ocular toxicity potential between legacy and alternative PFAS are lacking. To address this research gap, zebrafish larvae were exposed to both legacy PFAS (i.e.

Size-dependent seizurogenic effect of polystyrene microplastics in zebrafish embryos.

The effects of polystyrene microplastic (PS-MP) size on neurotoxicity remain to be evaluated at various microsizes, and the seizurogenic effects of PS-MPs are unknown. This study aimed to evaluate the swimming behavior of zebrafish larvae under light-dark transitions after exposure to four PS-MP sizes (i.e.

A benzothiazole-based fluorescent and colorimetric probe for the detection of ClO and its application to zebrafish and water sample.

A benzothiazole-based fluorescent and colorimetric chemosensor BZD ((E)-2-(benzo[d]thiazol-2-yl)-5-((4-(diethylamino)-2-hydroxybenzylidene)amino)phenol) was applied for detecting ClO. BZD showed fluorescence quenching and color variation for ClO via oxidative reaction between ClO and the imine bond. It could effectively detect ClO over various competitive analytes.
