WATER QUALITY ASSESSMENT USING WATER QUALITY INDEX: A CASE OF THE RAY RIVER, VIETNAM
نویسندگان
چکیده
Sông Ray là một trong những hệ thống sông chảy qua tỉnh Đồng Nai và Bà Rịa - Vũng Tàu. Nước có tầm quan trọng việc phục vụ sinh hoạt, công nghiệp nông nghiệp. Tuy nhiên, hiện nay chất lượng nước ngày càng ảnh hưởng nghiêm bởi các hoạt động vui chơi giải trí, du lịch, chăn nuôi, phân bón thuốc trừ sâu. Do đó, nghiên cứu nàyđược thực với mục đích xác định đánh giá thông số hóa lý trọng. Mẫu được thu kỳ 4 tháng năm 2019 (tháng 3, 6, 10, 12) giữa hai mùa khô mưa bao gồm 13 như nhiệt độ, pH, độ đục, oxy hòa tan (DO), amoni (NH4-N), nitrat (NO3-N), nitrit (NO2-N), photphat (PO4-P), tổng rắn lơ lửng (TSS), sắt (Fe), nhu cầu học (COD), (BOD5) coliform. Phương pháp tích mẫu dựa theo phương chuẩn Andrew, 1995. Kết quả sau đợt cho thấy tại vị trí M2, M3 (mùa khô) M9, M10 mưa) bị ô nhiễm nặng nhất. Ngoài ra, chỉ WQI cao hơn mưa. Vì vậy, ý nghĩa kiểm soát quản môi trường mặt ở Việt Nam.
