Các khía cạnh thủy hóa học trong khu vực cải tạo, Sydney, Úc
Tóm tắt
Nghiên cứu hiện tại được thực hiện để điều tra ảnh hưởng của kích thước hạt biến đổi đến nồng độ của các kim loại vi lượng ô nhiễm do con người gây ra trong khu vực cải tạo gần cảng Jackson, Sydney, Úc. Ở các khu vực cải tạo bị ảnh hưởng bởi nước ngầm, nồng độ kim loại vi lượng trong đất bị ảnh hưởng lớn bởi tính không đồng nhất của các vật liệu thải được chôn tại hiện trường. Các tác động kỳ quặc của kích thước hạt biến đổi trong đất có thể được giảm thiểu bằng cách phân tích nồng độ ô nhiễm của vật liệu sau khi loại bỏ kích thước >2 mm trong mẫu. Một ví dụ từ cảng Sydney được sử dụng để chứng minh tính tương đồng giữa dữ liệu chuẩn hóa theo kích thước hạt và dữ liệu chuẩn hóa theo nguyên tố sử dụng Fe trong đất từ các khu vực cải tạo. Kết quả từ nghiên cứu hiện tại cho thấy sự phân bố theo chiều dọc của nồng độ kim loại vi lượng trong đất có sự tương đồng đáng kể giữa chuẩn hóa kích thước hạt và chuẩn hóa nguyên tố, sử dụng Fe.
