Data for: Effects of pH and nitrites on the toxicity of a cypermethrin-based pesticide to zebrafish embryos

The aim of this study was to evaluate the influence of pH and nitrite concentrations on Barrage® toxicity using zebrafish (Danio rerio) as model organism and measuring lethal and developmental endpoints. Data provided refers to the observations of selected parameters in individual organisms. Mortality, development and hatching produced binomial data (0= not observed, 1= observed), while hear beats countings produced numeric data.
