Figure 2

Alterations in the dissolved organic matter (DOM) characteristics as observed by (left) Fourier transform ion cyclotron mass spectrometry (FTICR MS) and (right) 1H nuclear magnetic resonance (NMR) spectroscopy. Top: hierarchical cluster analysis (HCA; A) and principal component analysis (PCA; B) of four pristine control DOM (cf. Figs 4A and S1). Bottom: HCA (C) and PCA (D) of the control, effluent and downstream DOM (cf. Figs S6–S9). Colour code: green, control DOM; red, aquaculture effluent DOM; blue, DOM downstream of the aquaculture.
