The Empirical Relationship between Mining Industry Development and Environmental Pollution in China

Abstract

This study uses a vector autoregression (VAR) model to analyze changes in pollutants among different mining industries and related policy in China from 2001 to 2014. The results show that: (1) because the pertinence of standards for mining waste water and waste gas emissions are not strong and because the maximum permissible discharge pollutant concentrations in these standards are too high, ammonia nitrogen and industrial sulfur dioxide discharges increased in most mining industries; (2) chemical oxygen demand was taken as an indicator of sewage treatment in environmental protection plans; hence, the chemical oxygen demand discharge decreased in all mining industries; (3) tax reduction policies, which are only implemented in coal mining and washing and extraction of petroleum and natural gas, decreased the industrial solid waste discharge in these two mining industries.

An Evaluation Model for Urban Comprehensive Carrying Capacity: An Empirical Case from Harbin City

“…The primary indicator of social culture consists of 96 system elements, and its appraisal rate was 197 times, while the average appraisal rate was 2.05 times. The six system elements were resource awareness (33 times), environmental awareness (21 times), energy awareness (16 times), awareness of conservation (15 times), environmental protection (13 times), and energy conservation (11 times) [12,23,39].…”

“…Previous studies have contributed to the definition, implementation, and the evaluation of the carrying capacity to improve urban sustainable development, especially for coastal cities with their own rich economies and resources. However, problems such as haze weather, land subsidence, traffic congestion, and heavy metal pollution of soil have also occurred recently because of insufficient urban carrying capacities [12]. These issues arose because those urban carrying capacities could not meet the needs of urban development and human life [13] because the urban carrying capacity can be changed according to the resources and population.…”

Lala clam (Orbicularia orbiculata) shell as an eco-friendly adsorbent for Cd(II), Cu(II) and Pb(II) ions

“…Mining, batteries and plating manufacturing are the main sources of metal ions in industrial wastewater, which must be treated prior to discharge (Alharbi, Basheer, Khattab, & Ali, 2018). In 2014, approximately 2531.67 million tonnes of wastewater were discharged by the mining industry in China (Li, Lei, Ge, & Wu, 2017).…”

“…Various methods such as chemical precipitation, coagulation-flocculation, ion exchange and adsorption have been employed for sequestering heavy metals from aqueous solutions (Li et al, 2017). In developing countries, some aspects such as simple operation and low operational cost must be taken into consideration when a method is chosen to treat water (Aziz, Abdelmajid, Rachid, & Mohammadine, 2018;Saravanan et al, 2016).…”

The Research of Extracting Soluble Sylvite from Breeding Wastewater

“…In 2009, nationwide animal manure achieved 3.264 billion t, 1.6 times of industrial solid waste in the same term [2]. It is estimated that the amount would be as high as 4.244 billion t in 2020 [3].When the amount of livestock and poultry is grown, the influence is bigger, such as the waste water from the farm with many contamination could pollutes badly the clear water and cropland if waste water was push out direct without suitably management [4][5][6][7][8]. In the end, this is no more clear water for living and the cropland for food.…”
