Researchers used high performance liquid chromatography and untargeted metabolomics by Fourier-transform ion cyclotron resonance-mass spectrometry to highlight the critical role of root exudates in ...

Food additives are chemical substances added to improve organoleptic characteristics, in this context, there are several synthetic dyes, such as sunset yellow, tartrazine, erioglaucine, allura red, ...

Changes in the molecular composition of dissolved organic matter (DOM) and its light-absorbing component (CDOM) along the river–coastal ocean continuum are crucial for better understanding the source ...

PFAS, a family of thousands of human-made chemicals, are everywhere, and some of them are known to be harmful for our bodies and the environment. Even more frightening is how little we know about ...

APCI(+)FT-ICR MS; paraffin; HTGC; GC×GC-MS; NMR Five paraffin standards, named standards P1-P5, containing carbon numbers ranging from C 5 to C 120 (analytical grades with purity higher than 99.5%) ...

Three humic brown-water lakes (DOC concentration range 21.2–23.7 mg C L −1; Specific UV absorbance at 254 nm (SUVA 254) range 3.3–4.1 L mg C −1 m −1), Lumpen, Ramsjön, and Övre Långsjön, were sampled ...
