Asian green mussel is a marine animal that is used as food by most Indonesians. The mussels are widely cultivated in tropical countries such as Indonesia, Malaysia, Thailand, and other Asian countries. The mussel, known as perna viridis, is marine biota that is a filter feeder in the waters. Therefore, the quality of its meat is greatly influenced by the quality of the sea in its habitat. It is a food that is quite popular with the community but can endanger public health due to the accumulation of heavy metals. This study used a literature review by collecting data related to heavy metal concentrations in green mussel tissue in Indonesia. The results showed that the mussels from several sampling locations still exceeded the maximum acceptable limits of lead (Pb), mercury (Hg), and cadmium (Cd) concentration according to the standards of the food and drug administration of the Republic of Indonesia. Consumption of green mussels can increase health risks if you frequently consume them from cultivating or catching locations that have been contaminated with heavy metals.

Depending on the physiological process investigated heavy metal phytotoxicity can be either inhibitory or stimulatory. Photosynthesis and its partial light and dark reactions are inhibited; the activity of various enzymes, located in several cell compartiments, is increased. These enzymes are mostly induced since metals affect the transcription activity. They appear to be related to the plant defence against oxidative stress caused by metal phytotoxicity. Careful examination of the time course of this induction reveals differences in response between the metals applied

Objectives:The purpose of this study was to evaluate the heavy metal contamination level by analyzing heavy metals in sediments near Ieodo ocean research station located in southwestern Jeju Island. Methods:Sixteen sediments samples were collected from Ieodo ocean research station, and two and three sediment samples were collected from the southwestern region and between Ieodo and Jeju Island. These samples were used for heavy metal content analysis according to the marine pollution process test method, and contamination level of sediments was calculated using the measured heavy metal concentration. Results and Discussion:All heavy metals except Ni were evaluated as non-contamination level, and Ni was found to have high pollution level. According to the US Environmental Protection Agency guideline, samples 6, 9, 15, and 22 were classified as severe contamination, and according to the geoaccumulation index, samples 15 and 22 were classified as slightly contaminated for Ni. When classified by the Enrichment factor value, Ni contamination was categorized as moderately severe enrichment for samples 15 and 22. Using the potential ecological risk factor value, the ecological risks of the heavy metals in all samples were classified as low risk. The mean PEL quotient value for all six heavy metals in samples was a maximum of 0.60, indicating a 21% probability of toxicity for heavy metals in all samples.Conclusions:It was confirmed that there was no contamination by Cd, Cr, Cu, Pb, and Zn, but contamination by Ni was found to be a serious level. Compared with previous studies, the concentration of Ni in the Ieodo was found to be high, which may be due to the inflow of ocean research station or the Yangzu river runoff in China.
