Spatial analysis connects excess water pollution discharge, industrial production, and consumption at the sectoral level

Abstract

Linking of ‘consumption-industrial production-surface water deterioration’ is essential for industrialised economies to understand the mechanism of industrial water pollution. However, such a connection may mislead policy decisions if sectoral details are lacking. This study investigated excess pollution discharge from 11,094 industrial enterprises comprising 22 economic sectors through setting discharge thresholds on 1338 water function zones in Jiangsu Province, the most industrialised province in China. We further evaluated the contribution of final consumption in Chinese provinces to excess pollution discharge in Jiangsu via a national multi-region input–output table. Notably, despite typically heavy polluting sectors contributing the maximum excess pollution discharge, high-tech manufacturing sectors had a higher level of risk for excess pollution discharge. This was attributed to the spatial agglomeration of these sectors, with enterprises typically located in industrial parks. The increasing final consumption of specific sectors in both Jiangsu and other provinces may further drive excess pollution discharge in Jiangsu.

Large Virtual Transboundary Hazardous Waste Flows: The Case of China

“…In response, the Chinese government has taken measures, such as enforcing the ban on informal operations via Central Environmental Inspections and strengthening data quality management at multiple stages of data collection. Currently, the CESD is regarded as the best available and the most reliable data reflecting hazardous waste generation in China. − With the development of China’s whole life cycle management of hazardous waste, such uncertainties will be gradually reduced.…”

Selective dye adsorption by pH modulation on chemically modified nanopolyaniline by N-grafting of maleic acid

“…The TEM image was obtained using a JEOL TEM2100plus. 1 H NMR spectra were recorded with a JEOL (400 MHz) and a Bruker Avance III (400 MHz) spectrometer using DMSO-d 6 as the solvent. An Agilent Carry 100 spectrophotometer was used for recording the UV-vis spectra in the range of 200-800 nm.…”

“…The industrial revolution and technical development have led to the introduction of numerous industrial effluents into the ecosystem, producing environmental effects. 1 The progress of the dyeing and textile industries has led to the discharge of large amounts of toxic materials into the water system, which causes a series of environmental issues. Among the various organic toxic materials, the release of synthetic dyes into the hydrosphere represents a significant cause of water contamination due to their contumacious character, which introduces undesirable pigments into aquatic bodies, which in turn reduces light penetration and disrupts photochemical and natural cycles of aquatic life.…”

Mangifera indica stone-assisted layered double hydroxide biocomposites: efficient contenders for reactive dye adsorption from aqueous sources

“…As a result of industrialization, urbanization, increase in population size and over-exploitation, the quality of the world's water supply has declined significantly in recent decades. [1][2][3][4][5] The main sources of water pollution are agricultural run-off, sanitary waste and, most importantly, industrial discharges. A wide range of harmful chemicals and compounds, including dyes, [6][7][8] pesticides, [9][10][11] heavy metals, [12][13][14] endocrine disruptors, 15,16 etc., have recently been found in toxic concentrations in drinking water around the world.…”
