Abstract

The purpose of this paper is to know the content of heavy metal Pb in water, sediment and lindur (Bruguiera gymnorrhiza) at Ecotourism Mangrove Wonorejo Surabaya. The research methodology of this paper using descriptive quantitative method and with use water, sediment and lindur (Bruguiera gymnorrhiza) as the sample that taken at station I, II, III with 3 replications. Physical parameter including temperature, pH, and salinity were tested directly in the field, while the heavy metal content of Pb was tested using AAS method. Finding of the research showed that water, sediments and lindur (Bruguiera gymnorrhiza) in Ecotourism Mangrove Wonorejo has been contaminated by heavy metals Pb. Originality of this research explain that the average content of heavy metal Pb in water at station I 0,92 mg/L, station II 0,86 mg/L, and station III 1,08 mg/L, heavy metal concentration of Pb in water has exceeded the limit of the quality standard of water according to Decision of Environment Minister Number 51 of 2004 that is 0,05mg/L. The content of heavy metal Pb in sediments at station I 2,69 mg/Kg, station II 2,92 mg/Kg, and at station III 2, 98 mg/Kg, heavy metal Pb is still below the limit according to the government regulation of Indonesia Number 85 of 1999 is 5,0 mg/Kg. The average content of heavy metal Pb on lindur (Bruguiera gymnorrhiza) are at station I 0,13 mg/Kg (epidermis layer 0,10 mg/Kg, mesodermis 0,04 mg/Kg, and endodermis 0,26 mg/Kg), station II 0,15 mg/Kg (epidermis 0,13 mg/Kg, mesodermis 0,05 mg/Kg and endodermis 0.27 mg/Kg), station III 0,16 mg/Kg (epidermis layer 0,14 mg/Kg, mesodermis 0,06 mg/Kg and endodermis 0,29 mg/Kg), which has not exceeded the limit set by Directorate General of Food and Drug Administration Decree Number 03725/B/SK/VII/1989 of 2,0 mg/Kg.
