KONSUMSI IKAN LAUT KADAR MERCURY DALAM RAMBUT DAN KESEHATAN NELAYAN DI PANTAI KENJERAN SURABAYA (Sea Fish Consumption, Degree of Mercury Content in Hair, and Fisherman Health at Surabaya Kenjeran Beach, Indonesia)

Abstract

ABSTRAK

Pantai Kenjeran di Surabaya mempunyai banyak fungsi baik sebagai tempat rekreasi, perikanan serta tempat pembuangan limbah dari kota Surabaya. Studi sebelumnya telah menjelaskan bahwa pantai Kenjeran telah tercemar khususnya Hg. Polutan ini telah diindikasikan terdapat dalam ikan yang dikonsumsi masyarakat sekitar. Penelitian ini mengkaji dampak mengkonsumsi ikan dari Kenjeran kaitannya dengan kesehatan masyarakat yang menkonsumsi ikan. Peneliltian ini rnengambil sample 70 orang yang mengkonsumsi ikan dan 45 orang sebagai kontrol grup. Dalarn penelitian ini rambut responden diambil dan dikaji dengan Atomic Absorption Spectrophotometer (AAS). Penelitian ini menghasilkan bahwa responden yang mengkonsumsi ikan sebanyak rata-rata 99,11 gram/hari mempunyai kadar Hg dalam rambutnya sebesar 0.511 ppb. Penelitian ini mengindikasikan gejala-gejala penyakit yang terjadi pada mereka yang rnengkonsumsi ikan antara lain ginjal, pusing-pusing, tumor, pendarahan gusi, dan gangguan penglihatan. Penelitian ini rnenyimpulkan adanya korelasi yang signifikan antara responden yang mengkonsumsi ikan yang tercemar dengan kadar Hg dalam rambutnya.

ABSTRACT

Surabaya Kenjeran Beach, as a part of Eastern coastal area at East Java, functions as a sea recreation place and fishing. The condition of Surabaya Kenderan Beach is polluted by Hg as observed by previous researchers. They suggested that water, sediment, and fish from Kenjeran beach were already contaminated by Hg at dangerous level. Fisherman communities is one of the group which have a risk of getting affected by methyl Hg, because they usually consume fish from sea. This research is to study the relationship between consumption of sea fish and degree of Hg in fisherman’s hair, to measure the average degree of Hg in their hair and then to compare it with limit value. It is also studying the health disorder that likely appears as a result of Hg poisoning. This research took place at Kenjeran district, Bulak sub district, Surabaya. The number of samples for group who affected by Hg are 70 persons and controlled group are 45 person. Respondent’s hair (research subject) was taken and then observed by Atomic Absorption Spectrophotometer (AAS) No Flame. In conclusion, statically there is a significant relationship between the consumption of sea fish and the degree of Hg in hair. The average degree of Hg in the affected group’s hair is higher than that of the controlled group. However, it does not exceed the limit value recommended by the National Research Council (NRC). Also, there is significant relations between degree of Hg in hair and healthy disorder sigh (subjective symptoms).
