Bulk/wet deposition of trace metals to rural, industrial, and urban areas in the Yangtze River Delta, China.

The bulk depositions of trace metals to three land uses in the Yangtze River Delta are investigated based on the collected 154 precipitation samples from August 2015 to May 2017. The volume-weighted mean (VWM) concentrations of Ni, Cu, Zn, Cd, and Pb were 13.28, 5.

Detecting Sulfuric and Nitric Acid Rain Stresses on Quercus glauca through Hyperspectral Responses.

Acid rain, which has become one of the most severe global environmental issues, is detrimental to plant growth. However, effective methods for monitoring plant responses to acid rain stress are currently lacking. The hyperspectral technique provides a cost-effective and nondestructive way to diagnose acid rain stresses.

Dry Particulate Nitrate Deposition in China.

A limited number of ground measurements of dry particulate nitrate deposition (NO) makes it difficult and challenging to fully know the status of the spatial and temporal variations of dry NO depositions over China. This study tries to expand the ground measurements of NO concentrations at monitoring sites to a national scale, based on the Ozone Monitoring Instrument (OMI) NO columns, NO profiles from an atmospheric chemistry transport model (Model for Ozone and Related chemical Tracers, version 4, MOZART-4) and monitor-based sources, and then estimates the NO depositions on a regional scale based on an inferred model. The ground NO concentrations were first derived from NO columns and the NO profiles, and then the ground NO concentrations were derived from the ground NO concentrations and the relationship between NO and NO based on Chinese Nationwide Nitrogen Deposition Monitoring Network (NNDMN).

A Review of Spatial Variation of Inorganic Nitrogen (N) Wet Deposition in China.

Atmospheric nitrogen (N) deposition (Ndep), an important component of the global N cycle, has increased sharply in recent decades in China. Although there were already some studies on Ndep on a national scale, there were some gaps on the magnitude and the spatial patterns of Ndep. In this study, a national-scale Ndep pattern was constructed based on 139 published papers from 2003 to 2014 and the effects of precipitation (P), energy consumption (E) and N fertilizer use (FN) on spatial patterns of Ndep were analyzed.
