causing deleterious effects on aquatic organisms and therefore, the concern of their effects
to aquatic organisms has been increased. In this study, acute toxicity of methylparaben
(MeP), ethylparaben (EtP), and propylparaben (PrP) was assessed in the marine copepod
Tigriopus japonicus. The acute toxicity assessment resulted in the median lethal
concentration (LC50) values of MeP, EtP, and PrP were 29,754, 11,659, and 113 μg/L …
