Abstract

In the past 30 years, China’s economy has experienced rapid development, which led to a vast increase in energy consumption and serious environmental pollution. Among the different types of pollution, heavy metal pollution has become one of the major environmental issues in China. A number of studies show that high level of heavy metal exposure is a frequent cause of permanent intellectual and developmental disabilities. In recent years, some traditional pollutants, such as sulfur dioxide and carbon dioxide, have been put under control in China. However, heavy metal pollution, which poses even greater risks to public health and sustainable development, has yet to gain policymakers’ attention. The purpose of this paper is to explore effective countermeasures for heavy metal pollution in China. The present study reviews the current status of China’s heavy metal pollution and analyzes related public policies and countermeasures against that pollution. It also presents a few recommendations and measures for prevention of heavy metal pollution.

Highlights

  • Heavy metal pollution is an inorganic chemical hazard, which is mainly caused by lead (Pb), chromium (Cr), arsenic (As), cadmium (Cd), mercury (Hg), zinc (Zn), copper (Cu), cobalt (Co), and nickel (Ni) [1]

  • The purpose of this paper is to explore effective measures to reduce levels of heavy metal pollution through analyzing the status of heavy metal pollution and policies related to pollution control

  • Yangtze River basin is a principle region for heavy metal pollution control and waste water discharged in this area accounted for 17.8% of the national total discharges

Summary

Introduction

Heavy metal pollution is an inorganic chemical hazard, which is mainly caused by lead (Pb), chromium (Cr), arsenic (As), cadmium (Cd), mercury (Hg), zinc (Zn), copper (Cu), cobalt (Co), and nickel (Ni) [1]. In the past 30 years, China’s economy has experienced rapid development. It led to a huge increase in energy consumption and environmental pollution. Among various types of pollution, heavy metal pollution is a crucial environmental problem. Some traditional pollutants, such as sulfur dioxide and carbon dioxide, have been put under control, but heavy metal pollution, which poses even greater risks to public health, have yet to gain policymakers’ attention. In China, the environmental pollution caused by heavy metals has become increasingly prominent.
