Hasil menunjukkan bahwa kandungan logam Pb lebih tinggi dibanding logam Cr dalam P. viridis dengan konsentrasi berturut-turut (3,876-4,117) mg/kg untuk logam Pb dan (0,179-0,283) mg/kg untuk logam Cr. Batas maksimal konsumsi kerang hijau yang aman dikonsumsi perminggu dari Perairan Morosari untuk individu dengan berat badan 60 kg yaitu 0,364 kg/minggu untuk logam Pb dan 4,94 kg/minggu untuk logam Cr.
