“…Heavy metals and metalloids could enter various environmental media, including soil, dust, drinking water, ambient air and food (Granero and Domingo, 2002;Nadal et al, 2005;Wang and Stuanes, 2003), and they may enter the human body through dermal contact, inhalation and ingestion exposure from environmental media. Previous studies have conducted human health risk evaluations of heavy metals through various exposure pathways (Baastrup et al, 2008;Hough et al, 2004;Man et al, 2010;Mari et al, 2009), but little research on the key exposure route has been performed (Qu et al, 2012), with even less focus on coking plants due to the lack of systematic multipathway risk analyses.…”

• The concentration of heavy metals and metalloids in environment and children's blood are observed around the Chinese largest coking plant.• The health risk assessments of children are analyzed.• Foods from the coking plant are heavily contaminated by As, Cr and Se.• Food Ingestion pathway contributes most to children's average daily dose for most heavy metals and metalloids.• Higher potentially non-carcinogenic and carcinogenic risks happen to the local children. a b s t r a c t a r t i c l e i n f o Coking influences environmental quality and poses high risks to human health as large amounts of heavy metals and metalloids are emitted into the environment from coal during the coking process. Health risks depend heavily on multi-pathway and element-specific exposures, which have, unfortunately, been rarely studied. In this study, children's health risks and exposure levels to As, Se, and heavy metals (Pb, Cd, Cr, Ni, Co, Zn, Cu, Mn, V and Sb) in the water, soil, dust, air and locally produced food were studied based on field sampling and questionnaire-based surveys around the largest coking area in China. Human blood samples were collected and analyzed to indicate the exposure levels. The non-carcinogenic risks to children mainly resulted from Cr, Mn, Pb, As and Sb, the levels of which were 3 to 10 times higher than the acceptable levels (1.0 × 10 −6 ). The carcinogenic risks to children were 30 to 200 times higher than the safe level (1.0 × 10 −6 -1.0 × 10 −4 ), which could be attributed to Cr, As and Ni pollution. The estimated risks mainly came from the pathway involving the ingestion of locally produced food, accounting for more than 85% in total for most elements. For As, the food ingestion and air inhalation exposure pathways both contributed approximately 50%, respectively. The high risks in this study highlight the attention paid to the health of children who live in the vicinity of coking activities and the importance of site-specific multi-pathway health risk assessments and food safety to protect potentially exposed children.

“…Heavy metals have been found widely in various environmental media (including soil, water, air and food) around the world [5,15,16]. These species may enter the human body through inhalation of dust, direct ingestion of soil and water, dermal contact of contaminated soil and water, and consumption of vegetables grown in contaminated fields.…”

Heavy Metal Contamination of Water and Soil

Heavy metal pollution is becoming a serious issue in developing countries such as China, and the public is increasingly aware of its adverse health impacts in recent years. We assessed the potential health risks in a lead-zinc mining area and attempted to identify the key exposure pathways. We evaluated the spatial distributions of personal exposure using indigenous exposure factors and field monitoring results of water, soil, food, and indoor and outdoor air samples. The risks posed by 10 metals and the contribution of inhalation, ingestion and dermal contact pathways to these risks were estimated. Human hair samples were also analyzed to indicate the exposure level in the human body. Our results show that heavy metal pollution may pose high potential health risks to local residents, especially in the village closest to the mine (V1), mainly due to Pb, Cd and Hg. Correspondingly, the residents in V1 had higher Pb (8.14 mg/kg) levels in hair than those in the other two villages. Most of the estimated risks came from soil, the intake of self-produced vegetables and indoor air inhalation. This study highlights the importance of site-specific multipathway health risk assessments in studying heavymetal exposures in China.

“…The emissions of SO 2 , soot and dust declined gradually, but the total volume of waste gas was rising year by year. The average annual volume of waste gas emitted was 359.4 billion m 3 . In 2008, a multi-stage sequential extraction procedure was applied to study the particulate matter up to 2.5 micrometers in size (PM2.5) at different elevations [9].…”

A Study of Heavy Metal Pollution in China: Current Status, Pollution-Control Policies and Countermeasures

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.
