Kajian Mikroplastik Pada Kerang Hijau (Perna viridis) dari Lokasi Budidaya dan Pasar di Kota Semarang Serta Efektivitas Depurasinya
AI summary Read the abstract
Researchers analyzed microplastic abundance and characteristics in green mussels (Perna viridis) from four sites in Semarang, Indonesia, finding contamination across all locations up to 14,469 particles per kilogram, and demonstrating that a 96-hour seawater depuration process reduced microplastic content by 88.28%.
Penelitian ini bertujuan untuk menganalisis kelimpahan dan karakteristik mikroplastik (MP) yang terakumulasi pada kerang hijau (Perna viridis) dari empat lokasi di Kota Semarang, serta mengevaluasi efektivitas depurasi dalam mengurangi kandungan MP. Penelitian dilakukan menggunakan metode deskriptif-analitik dan eksperimental. Sampel kerang dibedakan berdasarkan ukuran (kecil 2–5 cm dan besar >5 cm), masing-masing sebanyak 15 ekor dari setiap lokasi. Mikroplastik dianalisis menggunakan mikroskop stereo melalui teknik pencacahan visual, berdasarkan bentuk, warna, dan ukuran partikel. Depurasi dilakukan terhadap 15 ekor kerang dari lokasi budidaya Tambak Lorok selama 96 jam menggunakan sistem sirkulasi air laut yang telah didesinfeksi, dengan pengamatan setiap 24 jam. Hasil penelitian menunjukkan bahwa kelimpahan MP tertinggi pada kerang kecil ditemukan di BTL ST.3 (13.892,97 ± 6700,45 partikel/kg) dan pada kerang besar di PTL (14.469,49 ± 746,38 partikel/kg). Bentuk MP yang teridentifikasi meliputi fiber, film, fragmen, dan pelet, dengan warna dominan merah, cokelat, biru, dan hitam. Proses depurasi menunjukkan penurunan jumlah partikel MP dari 44 menjadi 6,8 partikel/kerang, dengan efektivitas sebesar 88,28% pada jam ke-96. Hasil ini menunjukkan bahwa kerang hijau di seluruh lokasi telah terkontaminasi MP, namun kandungannya dapat dikurangi secara signifikan melalui proses depurasi

Researchers examined the presence of microplastics in human blood samples from healthy adult volunteers, detecting polymer particles in a majority of participants at low concentrations. Polyethylene terephthalate, polyethylene, and polymethyl methacrylate were identified, providing the first direct evidence that microplastics circulate in human blood and potentially reach tissues via the bloodstream.

AI summary Read the abstract
Two microplastic analysis methods — filtration and non-filtration approaches — were compared for quantifying microplastic concentrations in green mussel (Perna viridis) tissue from 99 samples. The comparison aims to identify the most reliable and reproducible analytical method for monitoring microplastic contamination in shellfish.
Microplastic Concentration in Green Mussels (Perna viridis) in the Waters of Mandalle, Pangkajene Islands, South Sulawesi
AI summary Read the abstract
This Indonesian-language study measured microplastic concentrations in green mussels (Perna viridis) collected from waters off South Sulawesi, Indonesia. Microplastic particles were found in all mussel samples examined, reflecting contamination in the surrounding marine environment. As filter feeders and commonly consumed seafood, mussels are important indicators of microplastic exposure for local communities.
