Pearl Farming Micro-Nanoplastics Affect Oyster Physiology and Pearl Quality [PDF]
Environmental Science & Technology, 2023 Abstract Pearl farming is crucial for the economy of French Polynesia. Nonetheless, rearing structures contribute significantly to plastic waste, and the widespread contamination of pearl farming lagoons by microplastics has raised concerns about risks to the pearl industry. This study aimed to evaluate the effects of micro-nanoplastics
