Vi nhựa được xem là một trong những chất ô nhiễm cần được quan tâm giải quyết hiện nay trên toàn thế giới do sự phân bố rộng rãi và tồn tại lâu bền trong môi trường. Tuy nhiên, có rất ít nghiên cứu về vi nhựa ở Việt Nam, dẫn đến không đủ nguồn thông tin phục vụ cho công tác quản lý, giám sát nguồn ô nhiễm này. Nghiên cứu này khảo sát hiện trạng ô nhiễm vi nhựa ở một hồ nội thành tại thành phố Đà Nẵng, Việt Nam. Mật độ vi nhựa ở hồ Công Viên 29/3 dao động từ 850 vi nhựa/m3 đến 1300 vi nhựa/m3. Trong đó, vi nhựa dạng sợi và dạng mảnh là hai hình dạng phổ biến nhất được ghi nhận (chiếm 98,5% trong tổng số vi nhựa đã xác định). Hơn 79% vi nhựa dạng sợi tại khu vực nghiên cứu có kích thước < 2 mm. Kết quả nghiên cứu góp phần cung cấp cơ sở dữ liệu có giá trị để hiểu hơn về tình hình ô nhiễm vi nhựa ở hồ đô thị của Đà Nẵng.
