Tracing device for new pollutants

The utility model relates to the technical field of environment detection, in particular to a tracing device for new pollutants. The new pollutant source tracing device comprises a detection unit, a floating plate and a plurality of floating units, the floating plate is of a circular structure, the diameter of the floating plate is larger than the two wavelengths of the maximum wave of the water area, the floating units are arranged at the bottom end of the floating plate, and the floating units are of annular structures with the diameters sequentially increased. The multiple floating units are sequentially arranged in a sleeving mode with the center of the floating plate as the circle center, the detection unit is arranged at the center of the bottom end of the floating plate and used for detecting new pollutants in a water area, and the tracing device for the new pollutants can stably float in a river, so that the reliability of the tracing device in the working process is improved, and the tracing device i
