Opis:
A good water quality is essential to sustaining the life of the organisms. The determination of water quality is needed as a direction to monitoring the water pollution. The purpose of this study is to examine the quality of the water and to determine the water pollution index based on the physicochemical parameters in Mimika waters, Indonesia. The sampling of water quality was carried out in October 2016 at six stations (Moga, Puriri, Inaoga, Keakwa, Atuka and Pomako waters). Then, the results were compared with the standard of sea water quality for biota marine based on the Decree of the Minister of Environment No. 51 year 2004. This study showed that the physicochemical parameters of the waters, such as water turbidity, BOD, NH3 and heavy metals (Hg, As, Cd, Pb, Cu, Zn, Ni and Cr), are still appropriate to the biota marine in all study stations. However, there is a parameter for which the quality standards were exceed in all locations, including water salinity for coral and seagrass, NO3, PO4 and H2S. The result of pollution index calculation at coastal waters Mimika are classified as lightly polluted (Keakwa and Pomako waters), and moderately polluted (Moga, Puriri, Inaoga and Atuka waters) with the pollution index values of 3.51 to 6.95. It is important to notice that the parameters of quality standards which had been exceed such as NO3, PO4 and H2S are the environmental parameter for nutrient elements and can trigger eutrophication in the waters.

Opis:
The total concentrations of BDEs in Baltic herring, caught in different years (2002–08) from various areas of the Baltic, and in Atlantic herring (2006) can be reasonably well described by a single concentration vs weight relationship. Samples collected a few years earlier and analysed by others show a slightly different relationship. This indicates that the weight of the fish is an important factor determining the level of contamination and that the contamination apparently did not increase between 1999 and 2008. However, two Baltic herring samples collected in 2007 contained, for reasons unknown, very high concentrations of BDE 209. The BDE profiles (concentrations scaled to a sum of 100) varied a great deal. It is impossible to determine how much of this variation is real and how much is caused by errors in the analyses. The concentration of the BDE 75 was much higher in the Atlantic than in the Baltic herring. Even after taking this into consideration, however, the BDE profile in Atlantic herring is different from the BDE profiles in Baltic herring.
