Abstract

Fish play an important role in human nutrition and therefore need to be carefully and routinely monitored to ensure that there are no high levels of heavy metals being transferred to human through their consumption. This study has been carried out to determine level of heavy metals (Cu, Pb, and Cd) in water and angel fish, Chelmon rostractus collected from coast of Batam. We report levels of Cu, Cd and Pb in water and angel fish from Coast Batam using Atomic Absorption Spectroscopy (AAS). Level of heavy metals obtained in water and fishes were fluctuative. Cu was obtained in both, water and fish muscles. Level of Cu in fishes muscle still under the permissible limit, but it was exceeded permissible limit for water. Cd not detected in water, but it was obtained in fish muscles. Level of Cd in fishes from Tanjung Pinggir site was exceeded permissible limit. High level of Pb was found in water and fish muscles. Level of Pb in water and fish muscles were exceeded permissible limit. It is indicated that the coast Batam has contaminated with Cu, Pb and Cd. Key words: heavy metals, angel fish, marine pollution, Batam coastal

Abstract

b-cyfluthrin has been in agricultural use in the recent years for controlling Lepidopteran pest affecting leafy vegetables crops. The extensive use of synthetic pyrethroids like b-cyfluthrin has resulted in wide spread environmental contamination. A study on residue dynamic of b-cyfluthrin applied to kangkong-land has been conducted. Buldock 25 EC with maximum recommended dose was used. The analysis was performed on kangkong land while land without kangkong used as control. Extraction was carried out with the soxhlet method, while the cleaning up process was carried out with carbon-and-florisil-double-layered column. High resolution gas chromatography with Electron Capture Detector (ECD) was used to determine the concentration. On  kangkong-land with 14,52% organic matter, sorption of b-cyfluthrin was observed. Residue of b-cyfluhtrin on soil increased to 16th days. The dissipation rate on land without kangkong and kangkong-land are fast with dissipation rate 2,5 x 10-1 day-1  and 5,76 x10-1 day-1respectively. Organic matter play an important role in the dissipation rate of b-cyfluthrin residue in the tropical farmland of Indonesia.

Abstract

The objective of the present study was to analyze the metal content of copper and lead in Enhalus accoroides seagrass in Batam Island waters. Samples of seagrass (E. accoroides) were collected from six locations along the western region of Batam Island then dried and performed with acid destruction. The measurements of Cu and Pb in the samples were conducted by Atomic Absorption Spectrophotometer. The result showed that there was an increasing of copper and lead contaminant level on sample E accoroides during two periods in a year.  The Cu level ranged from 0.63 to 46.1 mg/kg, meanwhile, lead level ranged from  2.14 to 10.52mg/kg respectively. The highest accumulation of copper and lead were recorded on leaves, it was reached 10.81 mg/kg and 5.98mg/kg, respectively.Penelitian ini bertujuan menganalisis kandungan logam tembaga (Cu) dan timbal (Pb) pada lamun Enhalus accoroides di sepanjang perairan barat Pulau Batam. Sampel lamun dikumpulkan dari enam lokasi  kemudian dikeringkan dan dilakukan destruksi dengan asam. Penentuan kadar logam tembaga dan timbal dalam sampel dilakukan dengan spektrometri serapan atom. Hasil penelitian menunjukan adanya peningkatan kadar logam Cu dan Pb pada sampel lamun E. accoroides selama 2 periode sampling dalam 1 tahun. Kadar logam Cu dan Pb pada lamun secara berturut berada pada rentang 0.63-46.1 mg/kg dan 2.14-10.52mg/kg. Akumulasi logam Cu dan Pb dalam lamun E. accoroides tertinggi pada bagian daun sebanyak 10.81 mg/kg Cu dan 5.98 mg/kg Pb.
