Heavy metal Pb accumulation on tiger prawn (Penaeus monodon) body in different salinity levels

anglais. This research aimed to understand the implication of developing media salinity levels toward Pb metal accumulation concentrated on tiger prawn body (Penaeus monodon). The research was conducted at laboratory scale using complete random design with salinity treatments of 10, 15, 20, and 25 ppt repeated for three times. Every treatment unit was applicated with Pb heavy metal in compound form (CH3COO)2.Pb.3H2O in the amount of 2 mg/l. Pb accumulated concentration on tiger prawn body was analyzed by Atomic Absorption Spectrophotometer (AAS). Correlation of the treated salinity levels with Pb accumulated concentration on tiger prawn body was analyzed by regression. Research results showed that salinity significantly affected the Pb accumulation level. The higher salinities, the lower Pb accumulation concentration. Nevertheless, while part of the body which was most potential to accumulate Pb was the cirus viscerum, followed with exosceleton while the lowest was in the meat

indonésien. Penelitian ini bertujuan untuk mengetahui pengaruh tingkat salinitas media pemeliharaan terhadap konsentrasi akumulasi logam Pb dalam tubuh udang windu (Penaeus monodon). Penelitian dilakukan dalam skala laboratorium menggunakan rancangan acak lengkap dengan perlakuan salinitas 10, 15, 20, dan 25 ppt masing-masing diulang tiga kali. Setiap unit percobaan diaplikasikan dengan logam berat Pb dalam bentuk senyawa (CH3COO)2.Pb.3H2O sebesar 2 mg/l. Konsentrasi akumulasi Pb dalam tubuh udang windu dianalisis dengan Spektrofotometer Serapan Atom (AAS). Korelasi tingkat salinitas perlakuan dengan konsentrasi akumulasi Pb dalam tubuh udang windu dianalisis secara regresi. Hasil penelitian menunjukkan bahwa salinitas berpengaruh nyata terhadap tingkat akumulasi Pb. Semakin tinggi salinitas maka konsentrasi akumulasi Pb semakin rendah. Sedangkan organ tubuh yang paling berpotensi mengakumulasi Pb adalah organ dalam, kemudian exoskeleton dan terendah dalam daging
