Abstract

The oil pollution of whiting, horse mackerel, shrimp and algae; Ulva lactuca, Ceramium rubrum, Cystoseira barbata were investigated after Nassia tanker accident. The higher oil contamination was found in shrimp as 253.98 µg/g one month after and in the algae Ulva lactuca as 175.53 µg/g at four months after the accident. We propose algae and shrimps as the best means to monitor oil pollution in seawater.
