This paper summarized the features of mine environmental noise on working face, such as the variety of noise sources, the continuity of high intensity and slow attenuation in narrow space, etc.The main projects about noise forecasting and controlling on working face was emphatically expounded;the development status about mines machinery noise mechanism and environmental noise acoustic characteristics of space-time of these main research topics were also introduced.展开更多

Most of these chemicals are exposed into the natural environment during the life cycles of their production, transportation, storage, consumption, and as by-products and wastes. The rising rates of cancer, obesity, and infertility suggests that there are compounds recently introduced to the environment that have altered the chemistry of the human body, and it is only with the monitoring of xenobiotics such as Bisphenol A （BPA）, nonyphenols, estrogen （natural and synthetic） and other endocrine-disrupting compounds （EDCs） that patterns and links could be drawn. This paper investigates the safety, environmental and health （SHE） impacts caused by BPA, nonyphenols and estrogens. Derived from petroleum, bisphenol A is used in manufacturing plastic consumer products, including certain water bottles, in dental sealants for children＇s teeth, and in resins used to line tin cans. Nonyphenol is one of the by-products of alkylphenolpolyethoxilates which is widely used as nonionic surfactants. Synthetic estrogen used for birth control pills as well as natural estrogen excreted by women through urine enters the domestic wastewater streams. These compounds are considered to be EDCs and have severe SHE concerns. In this paper, the challenges of entry of these compounds （xenobiotics） into nature, health and environmental issues and their remediation have been reviewed in detail.展开更多

A key challenge in addressing the problem of food safety and protecting public health is building an integrated knowledge base to inform policy and strengthen governance. This requires breaking down the trans-departmental information barrier across the environment, food and health domains to ensure the effective flow of data and the efficient utilization of resources, and facilitate the collaborative governance of food safety. Achieving this will be crucial for the development of health and medical care in China in the era of big data. Currently, the information resources commanded by various departments are incomplete and fragmented. Data resources are also organized in vertical silos and there is a lack of data sharing within and across policy streams. To provide the basis for more effective integrated collection and analysis of data in future, this study summarizes the information resources of various departments whose work relates to interactions between environment, food and health, and presents measures to strengthen top-down design, and establish unified data standards and a big data sharing platform. It also points to the need for increased training of data analysts with interdisciplinary expertise.展开更多

It argues that it is misleading to extrapolate simply from levels of cadmium in soil to health risks, because the uptake of cadmium by crops and the health impacts of the metal are affected by multiple factors. These include not only background levels of cadmium and pollution from mining and industry, but also soil quality, climatic conditions and the type and variety of crops grown. Social and cultural factors, including dietary habits, other exposure sources, nutritional quality and general health status will also affect the intake of cadmium and the severity of health impacts. For these reasons we argue that interdisciplinary analysis is crucial to a better understanding of patterns of risk to health from cadmium pollution, and to the design of effective responsive measures.展开更多
