Abstract

Large quantities of wastewater from industries and households were released to Wonorejo river in Surabaya East Coast area. The concentration of Cu at the Wonorejo Estuary reached 3.186 mg/L at brackish water in 2009 One of the inorganic pollutants that can be removed by mangrove is copper (Cu). The purpose of this research was to determine the potency of Cu accumulation byAvicennia marinathat was grown for ten years at Wonorejo Estuary. The sampling activities were conducted using a transect quadrat sampling method with a 10x10 m dimension. There were ten points of location sampling, the sediment and root ofA. marinasamples were collected in those location sampling. All samples of sediment and root were extracted before those samples were analyzed using an atomic absorption spectrophotometer (AAS). The calculation of the Bioconcentration Factor (BCF) was conducted using a equation formulation. The results showed that concentration Cu in sediment was 27 mg/kg until to 150 mg/kg. The Cu accumulation by roots ofA. marinareached 53 mg/kg until to 128 mg/kg. The BCF value inA. marinawere 0.91 to 3.22 In conclusion,A. marinashowed potential as a hyperaccumulator for Cu.

Highlights

Surabaya East Coast region has a ecosystem mangrove forest
According to EPA sediment quality standard [14], a non polluted area was below 25 mg/kg, a range for Cu slightly polluted area were 25 – 50 mg/kg and concentration value for Cu severely polluted area was upper than 50 mg/kg
According to Pollution Control Department of Thailand, the limit of Cu concentration for Cu polluted area was below 16 mg/kg [15]

Summary

Introduction

Surabaya East Coast region has a ecosystem mangrove forest. The Many species of mangrove can grow well at the mangrove forest. This area has high levels of salinity [1]. River mouth area Wonorejo has various types of mangroves. Mangroves have a tolerance high against heavy metals. Heavy metal accumulation occurs on the roots, stems and leaves of mangroves [4]. Heavy metal pollution in mangrove areas can be caused from urban waste, agricultural waste, effluent Wastewater Treatment Plants (WWTP), industrial effluent waste, use of ships and chemical spills [5]
