Atmospheric nitrogen deposition (AND) may lead to water acidification and eutrophication. In the five months after December 2019, China took strict isolation and COVID-19 prevention measures, thereby causing lockdowns for approximately 1.4 billion people. The Danjiangkou Reservoir refers to the water source in the middle route of South-to-North Water Diversion Project in China, where the AND has increased significantly; thus, the human activities during the COVID-19 period is a unique case to study the influence of AND to water quality. This work monitored the AND distribution around the Danjiangkou Reservoir, including agricultural, urban, traffic, yard, and forest areas. After lockdown, the DTN, DON, and Urea-N were 1.99 kg · hm−2 · month−1, 0.80 kg · hm−2 · month−1, and 0.15 kg · hm−2 · month−1, respectively. The detected values for DTN, DON, and Urea-N in the lockdown period decreased by 9.6%, 30.4%, and 28.97%, respectively, compared to 2019. The reduction in human activities is the reason for the decrease. The urban travel intensity in Nanyang city reduced from 6 to 1 during the lockdown period; the 3 million population which should normally travel out from city were in isolation at home before May. The fertilization action to wheat and orange were also delayed.

“…This means that our measurements are in line with the values found in the same region and can be compared to the high deposition rates measured in Indonesia, China, Vietnam, Thailand, Japan, and Malaysia. As a comparison, in Europe wet N deposition ranges between 0.5 and approximately 20 kg ha -1 year -1 (Thimonier et al 2019, Zhang et al 2021. The primary source of NH4 + is agriculture, and the main source of NO3is the emission of NOx by industries and vehicles (Aderson and Dowing 2006).…”

“…Asia is now the global hotspot of N deposition. Since the early 2000s, the highest rates of global N deposition have been documented in various regions of Asia, including China, India (Gao et al 2020;Zhang et al 2021), Japan, and South Korea (Hu et al 2019). Some parts of Indonesia, China, Vietnam, Thailand, and Malaysia are hotspots of wet N deposition (24-102 kg N ha−1 yr−1) in Asia (Zhang et al 2021).…”

Effects of artificial nitrogen deposition on the forest floor and soil chemistry in chestnut-leaved oak (Quercus castaneifolia) plantation in northern Iran

et al. 2022

Human demand for food and energy has led to significant changes in the level of reactive nitrogen (Nr) released to the atmosphere and then deposited in the biosphere. This study aimed to investigate artificial N deposition's impact on the forest floor and soil chemical properties in an oak (Quercus castaneifolia C. A. Mey) plantation in the north of Iran. Twelve plots of 200 m2 (20 m × 10 m) were set up in the study area. Four N treatments were considered: zero (control), 50 (low), 100 (medium), and 150 (high) kg N ha−1 year−1. The total N, P, K, and organic C (OC) of the forest floor were measured. Soil N, available P, available K, pH, EC (Electrical Conductivity), OC, microbial biomass C (MBC), and urease enzyme activity were measured in the 0-10 cm depth. The concentration of total N and P of the forest floor was significantly higher in the high N treatment. The total concentration of N (+36%), the urease activity (+44%), and EC (+12%) of soil increased with raising the high-N treatment compared to the control, but the MBC (-20%), available P (-28%), and available K (-15%) were significantly reduced in the high-N nitrogen treatment.

“…The change process of various N elements in the sediment–water interface includes adsorption, sedimentation, biological nitrification, denitrification, assimilation, absorption, ammonization, and anaerobic ammonia oxidation reaction [ 15 ]. Moreover, wet and dry deposition in recent years has become an important contributor to the watershed in many parts of the world, particularly nitrogen by wet deposition [ 16 , 17 ]. P in the watershed mainly enters the soil through fertilization [ 18 ], and then part of the solution in the soil enters the plant through plant absorption, forming biologically bound organic P. Another part of the phosphate solution in the soil can be transformed between the adsorbed and free state by over-adsorption and desorption [ 19 , 20 ].…”

The impact of rainfall on water quality may be more important in semi-arid regions, where rainfall is concentrated over a couple of months. To explore the impact of rainfall changes on water quality, e.g., nitrogen (TN) and phosphorous (TP), the diversion from Luan River to Tianjin Watershed in the northern semi-humid area was selected as the study area. TN and TP concentrations in rivers and the Yuqiao Reservoir during the three-year high-flow season (2019–2021) were analyzed. The response relationship and influencing factors among the watershed’s biogeochemical process, rainfall, and water quality were clarified. The results showed that rainfall in the high flow season mainly controlled the river flow. The concentration of TN and TP in the inflow rivers is regulated by rainfall/flow, while the concentration of TN and TP in the water diversion river has different variation characteristics in the water diversion period and other periods. The lowest annual concentrations of TN and TP were observed in the normal year, while the highest annual concentration was observed in the wet year, indicating that the hydrological process drove the nutrient transport in the watershed. For the tributaries, the Li River catchment contributed a large amount of N and P to the aquatic environment. For the reservoir, the extreme TN concentrations were the same as the tributaries, while the extremes of TP concentrations decreased from the dry year to wet year, which was in contrast to the tributaries. The spatial variation of TN and TP concentrations in the reservoir showed that the concentration decreased following the flow direction from the river estuary to the reservoir outlet. Considering climate change, with the increase of rainfall in North China in the future, the TN and TP transport fluxes in the watershed may continue to increase, leading to the nitrogen and phosphorus load of the downstream reservoir. To ensure the impact of the increase of potential N and P output fluxes in the watershed on the water quality of the reservoir area, it is necessary to strengthen the effective prevention and control of non-point source pollution in the watershed.
