Pengumpulan data kematian dilakukan setiap jam selama 10 hari dengan mengamati jumlah telur yang mati disamping mengamati kematian juga tingkat kelangsungan hidup. Hasil analisis data mortalitas dengan nilai rata-rata dan standar deviasi didapatkan mortalitas embrio ikan medaka pada kontrol berbeda nyata dengan kelompok kontrol. Dampak toksikologi embrio lebih terlihat pada konsentrasi mortalitas yang lebih tinggi (2 mg/l) dibandingkan dengan konsentrasi yang lebih rendah (0,02mg / l). Insiden tertinggi sebesar konsentrasi deviasi standar (0,02mg / l).

Mortality data analysis results with the average value and standard deviation obtained mortality of medaka fish embryos at the control were significantly different from the control group. The embryo toxicological impact was more pronounced in higher mortality concentrations of (2mg/l) compared to lower concentrations (0.02mg/l).
