 Objective: Ulva reticulata is a marine edible green seaweed widely distributed along the coastal lines of India. The present study was designed to screen the phytochemicals and evaluate heavy metals content of U. reticulata collected from Rameshwaram, Tamil Nadu, India, in the perspective of assessing their therapeutic value and/or safety in relation to its uses.Method: The seaweed sample was subjected to extraction with solvents of different polarities (methanol, ethanol, acetone, chloroform, and petroleum ether) and screened for phytochemicals according to standard methods. Heavy metal analysis was also performed with the dried sample powder using inductively coupled plasma optical emission spectrophotometer (ICP-OES).Result: Preliminary phytochemical analysis revealed the presence of reducing sugar, proteins, flavonoids, glycosides, alkaloids, and anthraquinones. ICP-OES indicated the seaweed to contain relative amount of heavy metals in the order of iron (Fe) > chromium (Cr) > Zinc (Zn) > nickel (Ni) > copper (Cu) > lead (Pb) - cadmium (Cd) and is within the permissible limits set by the WHO/FAO, except Fe and Cr.Conclusion: The different solvent extracts of U. reticulata showed the presence of the number of phytochemicals. Furthermore, the present study has revealed the presence of heavy metals in U. reticulata which can be a representative picture of the dissolved metals in the aquatic phase.

Madura strait receives waste disposal from various activites in the mainland, making it vulnerable to contamination of harmful pollutants. Some of the harmful pollutants are heavy metal Pb and Cd. The high concentration Cd and Pb give negative impacts to the biota including bivalves. This study was conducted to assess the distribution of heavy metals Pb and Cd in the waters and their accumulation in bivalves Anadara nodifera, Meretrix lyrata, and Solen lamarckii in coastal waters of the West Madura Strait. Heavy metal analysis refer to APHA 2012 using AAS. The results showed that concentration of Cd and Pb in water were below the quality standards, while in sediment were above the standard (Cd of 7.20 mg/kg and Pb of 62.06 mg/kg). The concentration of Cd in bivalve were different among the species tested A. nodifera of 6.10 mg/kg, M. lyrata of 3.65 mg/kg, and S. lamarckii of 2.74 mg/kg, as well as Pb concentration A. nodifera of 60.10 mg/kg, M. lyrata of 51.48 mg/kg, and S. lamarckii of 45.29 mg/kg). These results indicated that the three shells have exceeded the maximum limit of heavy metal contamination in food (Cd of 1.0 mg/kg and Pb of 1.5 mg/kg). Keywords: bivalve, heavy metal, Madura Strait

Most of coastal waters of West Sumbawa are wave-exposed areas. As part of Alas Strait this region is located between Lombok and Sumbawa Island. On the land and coastal areas, mineral mining (i.e. gold) activities are operated massively by large private company (i.e. PT. Newmont Nusa Tenggara) and traditional mining by local communities. These activities (especially for traditional mining) are expected to increase the content of heavy metals in the marine and coastal waters surrounding. A residual of mining processing will produce heavy metals disposal. In this study, the distributions of heavy metals (i.e. Hg, Cr6+, Cu, As, Ni, Zn, Pb, and Cd) were measured in the water column and bed sediments of coastal waters of West Sumbawa. This study was conducted during dry season in July 2011. The results show the heavy metal concentrations in water column were mainly within the permissible limits (based on Keputusan Menteri Lingkungan Hidup No. 51, 2004). Except for Cu, the concentration was highest found on most of the stations. The heavy metal contents in bed sediment were low, but varied among sampling points. Furthermore, Cu content in bed sediment also found remarkably high (101,7 mg/Kg) with additionally Zn content was closed (10,6–105,5 mg/Kg) within the permissible limits (based on criteria by Australian and New Zealand Environment and Conservation Council – ANZECC, 2000).

The presence of heavy metals in coastal waters is a threat to the wealth of coastal ecosystems because they are toxic. The people activities of Makassar City are centered in the coastal area so that they have the potential to produce heavy metal pollutants that can escape into coastal waters. This study aimed to determine the distribution of heavy metal concentrations in the sediment and water column and to determine the contamination factor. The research location is along the coast of Makassar City by determining the location of the observation based on potential sources of input, namely ports, river estuaries, and tourism activities. The research method used survey methods with in-situ measurements (oceanographic parameters) and ex-situ (heavy metal concentrations) and data presentation using tables, graphs, and analysis of variance test results. The concentration of heavy metals Pb, Cd, and Zn in the sediment were higher and significantly different (p <0.05) compared to the water column, while Cu not different. There was no significant difference in the concentration of heavy metals (p> 0.05) spatially (ports, river estuaries, tourist sites). Heavy metals in the sediments did not exceed the quality standard, while several heavy metals in the water column exceeded the quality standards, namely Pb and Cd. The contamination level of heavy metal pollutants studied in the coastal waters of Makassar City was low (CF <1), and if sorted, a pattern of heavy metal was Cd> Zn> Pb> Cu. Keberadaan logam berat di perairan pesisir merupakan ancaman bagi kekayaan ekosistem pesisir sebab bersifat toksik. Aktivitas masyarakat Kota Makassar berpusat di daerah pesisir sehingga berpotensi menghasilkan bahan pencemar logam berat yang dapat lepas ke perairan pesisir. Penelitian ini bertujuan untuk mengetahui distribusi konsentrasi logam berat di sedimen dan kolom air serta menentukan faktor kontaminasi. Lokasi penelitian di sepanjang pesisir Kota Makassar dengan penentuan lokasi pengamatan berdasarkan potensi sumber masukan yaitu pelabuhan, muara sungai, dan aktivitas wisata. Metode penelitian menggunakan metode survey dengan pengukuran secara insitu (parameter oseanografi) dan exsitu (konsentrasi logam berat) serta penyajian data menggunakan tabel, grafik, dan hasil pengujian analisis varians. Konsentrasi logam berat Pb, Cd, dan Zn pada sedimen lebih tinggi serta berbeda secara signifikan (p<0,05) dibandingkan dengan kolom air sedangkan Cu tidak berbeda. Tidak terdapat perbedaan konsentrasi logam berat yang nyata (p>0,05) secara spasial (pelabuhan, muara sungai, lokasi wisata) Logam berat pada sedimen tidak melampaui baku mutu sedangkan pada kolom air terdapat beberapa logam berat yang melampaui baku mutu yaitu Pb dan Cd. Tingkat kontaminasi bahan pencemar logam berat yang diteliti di perairan pesisir Kota Makassar termasuk rendah (CF<1) dan bila diurutkan maka ditemui pola Cd>Zn>Pb>Cu.
