Abstract
Penelitian ini bertujuan untuk mengetahui adanya cemaran logam Timbal (Pb) dan jumlah cemarannya pada spesies ikan Petek dan ikan Teri di kawasan laut Teluk Palu. Metode yang digunakan adalah destruksi kering (dry ashing) kemudian dianalisis secara kualitatif menggunakan pereaksi : (1) KCN ditambah Ditizon 0,005%, (2) Serbuk KI dan (3) Serbuk Na2CO3, serta uji kuantitatif dengan metode Spektrofotometri Serapan Atom pada λmaks 217 nm. Hasil penelitian didapatkan bahwa pada pengujian kualitatif ikan positif mengandung logam timbal (Pb). Hasil pengujian kuantitatif didapatkan kadar rata-rata logam timbal (Pb) adalah : (1) Ikan Petek di lokasi Taman Ria 0,757 mg/kg ; (2) Ikan Petek di lokasi sekitar Muara Sungai Palu 1,752 mg/kg ; (3) Ikan Petek di lokasi sekitar Pantai Talise 0,719 mg/kg ; (4) Ikan Teri di lokasi Taman Ria 1,989 mg/kg ; (5) Ikan Teri di lokasi sekitar Muara Sungai Palu 2,075 mg/kg dan (6) Ikan Teri di lokasi sekitar Pantai Talise 1,655 mg/kg. Kadar logam timbal (Pb) pada kedua ikan tersebut telah melampaui nilai batas maksimum berdasarkan SNI 7387:2009 yaitu 0,3 mg/kg.
