Effect of acetochlor on S. costatum cell morphology (IMAGE)
Caption
The effects of three pesticides on S. costatum cell morphology were observed after exposure to different concentrations of acetochlor. a-e: The microalgae were exposed to 0, 0.01, 0.025, 0.1 and 0.25 mg/L acetochlor for 96 h respectively. The microalgal cells showed abnormal cell division and morphology (d) or cell shape disappeared completely and became a ‘cluster’ (e), when S. costatum was exposed to 0.1 or 0.25 mg L-1 acetochlor, respectively. The result indicated that the cell membranes of the microalgae were damaged by acetochlor. Photo credit: Qiulan Chen.
