However, the effects on invertebrate species are HSP70 not yet fully understood. The aim of this study was to determine the biochemical responses of Arbacia lixula Marine invertebrates exposed to high-frequency noise. Protein concentration, enzyme activity (esterase, phosphatase and peroxidase) Noise and cytotoxicity in coelomic fluid were compared in individuals exposed for three hours to consecutive linear Acoustic stimulus sweeps of 100 to 200 kHz lasting 1 s, and control specimens. Sound pressure levels ranged between 145 and Physiological stress 160 dB re 1μPa.
