Article Synopsis
- Anthropogenic reactive nitrogen (Nr) emissions from agriculture and food consumption in city clusters, like the Yangtze River Delta, have negatively impacted water quality and availability from 2011 to 2020.
- A reduction of 12.1% in nitrogen-related grey water footprint (GWF) was observed, primarily due to less fertilizer use and fewer livestock; by 2020, human activities became the main pollution source.
- The study suggests significant spatial trends in GWF and highlights that enhancing nitrogen use efficiency and recycling rates could potentially lower the GWF by 39.6%, offering insights for sustainable nitrogen management strategies.
Intensive anthropogenic activities associated with the food production and consumption system (FPC) drive massive reactive nitrogen inputs to city clusters resulting in serious nitrogen (N) pollution. We conducted a substance flow analysis to examine N flows in the FPC within the Yangtze River Delta city cluster from 2011 to 2019. The total N input and output showed parabolic downward trends, with decreases from 4008.

The contents of 10 selected heavy metals (Cr, Mn, Ni, Cu, Zn, As, Ag, Cd, Hg, and Pb) were analyzed. The results showed that the content of each heavy metal element did not exceed the values for Soil Environmental Quality of Risk Control Standard for Soil Contamination of Agricultural Land (GB15618-2018) and Development Land (GB 36600-2018).
