Heartbeat of Daphnia magna exposed to PFOS 48 h was stimulated significantly. 48h-EC50 was 79.35 mg L−1, the toxicity of PFOS was classified as intermediate. Intrinsic rate of natural increase was a sensitive parameter. Reproductive, antioxidant and neurological responses were significantly inhibited. At 8 mg L−1 concentration, most evaluated endpoints have sensitive effects.
