Abstract
Monitoring of marine sediments as an indicator of heavy metal mercury pollution in waters has been conducted. This study used an observational design with an Environmental Risk Analysis approach with the objective of knowing the concentration of mercury (Hg) heavy metals and the risk of metal contamination in marine sediments. Sediment sampling was conducted at 10 points in 5 (five) urban villages of Makassar City. The results showed that the highest mercury concentration was in Cambayya Village at 1.871 mg / kg and the lowest mercury concentration was in Lae-Lae Island Kelurahan at 1,550 mg / kg. In general, the content of heavy metals mercury in marine sediments in coastal areas of Makassar City has exceeded the threshold of 0.13 mg / kg with the enormous environmental risk occurring in coastal areas of Makassar City due to exposure to mercury metals, ranging from 11-22 under the risk category high HQ> 10.Keywords : Risk Analysis, Sea Sediments, Mercury

Konsentrasi merkuri tertinggi berada di Kelurahan Cambayya yaitu 1,871 mg/kg dan konsentrasi merkuri terendah berada di Kelurahan Pulau Lae-Lae yaitu 1,550 mg/kg dan besar risiko lingkungan yang terjadi di wilayah pesisir Kota Makassar akibat paparan logam merkuri, berkisar antara 11-22 dengan kategori risiko tinggi HQ>10
Summary
Sekretariat Editorial: Kampus FKM UNISMUH PALU - Palu 94118, PENDAHULUAN Laut merupakan tempat bermuaranya berbagai saluran sungai sehingga laut menjadi tempat terkumpulnya zat-zat pencemar yang dibawa aliran air (Sandi Purnawan, 2013). Dampak dari aktivitas tersebut secara langsung dapat menyebabkan masuknya limbah ke dalam ekosistem perairan yang salah satunya adalah logam berat. Hasil pemeriksaan kualitas air laut yang dilakukan rutin oleh Balai Besar Kesehatan dan Keselamatan Kerja (K3) Makassar di Perairan Pantai Losari menyatakan bahwa pada tahun 2010, Merkuri (Hg) tidak terdeteksi.
