Gridded dataset of industrial aquatic heavy metal emissions in China (1998-2010)

Introduction

The high-resolution grid dataset of industrial aquatic heavy metal emissions in China during 1998-2010 was constructed using a bottom-up approach. The emissions of five types of industrial aquatic heavy metals, including Hg, Cd, Cr(VI), Pb, and As, were calculated based on the monetary outputs of industrial enterprises and the corresponding emission coefficients. Subsequently, the heavy metal emissions of each enterprise were spatialized onto grid maps at the scale of 1 km×1 km to construct the grid emission dataset. The environmental impacts of industrial aquatic heavy metal emissions, including human health impacts and ecosystem quality impacts, were estimated based on ReCiPe2016.

The grid dataset can provide detailed information on the spatial distribution of industrial aquatic heavy metal emissions that can be used to refine aquatic heavy metal pollution control in China. It can also be used to analyze the environmental impacts and socioeconomic drivers of industrial aquatic heavy metal emissions.
