Abstract

Penelitian ini bertujuan untuk mengkaji perubahan struktur histologis organ insang, hati dan ginjal ikan nila akibat dari paparan merkuri. Penelitian dilakukan dari bulan Februari hingga Juni 2013. Ikan nila berukuran panjang 11-13 cm dengan bobot rata-rata 20 gram dipaparkan pada konsentrasi sub kronik merkuri klorida (0,164 mgL-1) selama 56 hari. Pembuatan preparat histologis hati dan dilakukan dengan metode histoteknik menggunakan pewarnaan Haemotoxylin dan Eosin. Hasil penelitian menunjukkan adanya pengaruh negatif pada hati dan ginjal ikan nila akibat dari paparan merkuri. Paparan merkuri pada organ insang menyebabkan terjadinya perubahan struktur histologis berupa perbesaran sel organ (hypertrophy), penambahan jumlah sel (hyperplasia) pembengkokan lamela sekunder (curling of secondary lamella), penghimpitan lamella sekunder (fusion in secondary lamella)  dan kematian sel  (neukrosis). Perubahan histologis pada organ hati berupa perbesaran sel organ (hypertrophy), penambahan jumlah sel (hyperplasia), penciutan inti  sel (shrinkage of hepatocytes), pendarahan (hemorage), dan kematian sel (neukrosis).Kata kunci: merkuri klorida, histologis, hypertrophy, hyperplasia, neukrosis.

Abstract

The source of iron in waters can come from human activities that carry out activities such as waste disposal in household and industrial activities. Green mussels containing iron are very dangerous for the shells themselves and for human health if consumed in excess. This study aims to analyze the concentration of iron in green mussel meat, determine the safe limit of green mussel meat for consumption by humans, and calculate the value of bioconcentration factors. This research was conducted in the sea of Tanjung Mas, Semarang. Samples taken in the form of green mussels, sediments, and water were then analyzed for iron concentrations with Atomic Absorption Spectrophotometer. The results of the study showed that the range of iron concentration values in green mussels from July to November was 39–283,97 mg/kg. The range of MTI values for adults was 1.18–4.92, while for children the range was 0.24–0.98. The value of the bioconcentration factor of green mussels and water was 3271–24839, while the value of the bioconcentration factor of green mussels and sediments was 0.010–9.647.

Abstract

Cadmium metal is dangerous for green mussel organisms because it can interfere with fertility. Green mussels are organisms widely distributed, can survive in poor environments, and sedentary organisms. Green shellfish is a filter feeder and is used as a bioindicator to monitor the concentration of Cd metal in the waters. The research objective was to measure the concentration of Cd metal in sea water, sediment, and green mussel meat in the waters of Tambak Lorok and Morosari. The Cd metal contents of seawater, sediments, and green mussels were measured using Atomic Absorption Spectrophotometer. The results showed that Cd metal concentrations in seawater in May, July, and August 2018 in Tambak Lorok and Morosari waters were below the detection limit (0.001mg/L); 0.002 mg/L; and 0.002 mg/L, respectively. The concentrations of cadmium in sediment in May, July, and August in Tambak Lorok waters were below the detection limit (0.004 mg/kg); 0.0023 mg/kg; and 0.0021 mg/kg, respectively, and in Morosari waters were below the detection limit (0.004 mg/kg); 0.002 mg/kg; and 0.0114 mg/kg, respectively. Cd metal concentrations in green mussel meats in May, July, and August in Tambak Lorok waters were below the detection limit (0.01mg/kg); 0.0060; and 0.1277 mg/kg, respectively, and in Morosari water were below the detection limit (0.01mg/kg); 0.0067 mg/kg; and 0.0493 mg/kg, respectively. Cd metal concentrations in sea water and green mussels in the waters of Tambak Lorok and Morosari were below the quality standard and the concentrations of Cd metal in seawater, sediments, and green mussel meat in the waters of Tambak Lorok and Morosari were not significantly different.

Abstract

AbstractWaste produced by industrial activities in Donan River can be a heavy metal which is one source of harmful pollutant to the aquatic environment. This study was conducted monthly from August 2015 to January 2016 at the waters of the Donan River estuary. The aims of this study were to analyze the content of heavy metals Pb, Hg, Cd and Cu in whiting fish muscle and determine the tolerance limit to consume fish containing the heavy metals. Commonly, the average content of heavy metal in the whiting fish muscle based on Atomic Absorption Spectrophotometry (AAS) reading exeded the standard limit determined, but there are also some fish whose heavy metal still below the standard limit. The values of heavy metal in the fish muscle range <0,005-9,19 ppm (Pb); 304,50-4535,22 ppb (Hg); 0,11-0,56 ppm (Cd); and 0,36-1,39 ppm (Cu). The maximum weight limit of fish muscle for adults (50 kg) and children (15 kg) are 17,64 g muscle per week and 5,29 g muscle per week, respectively.
