System dynamics model of financial and monetary mechanism are established on the basic of qualitative research in financial and monetary theory, by applying system dynamics to financial and monetary law of movement, development and change in economic system and simulating this law. With it, we can analyse the interrelations between finance and banking; analyse the quantity of money demanded by the economic system, determine the most desirable quantity of money demanded by the economic system; find out the extent to which financial and banking influence other economic variables, such as national income, market demand and price, etc., and propose methods and means to control them. This model provided a new method of research to secure a fine circle of finance and banking in economic system, and promote national economy of our country to develop in a continuous, stable and harmonious way. 展开更多

The environmental and health impacts from the massive discharge of chemicals and subsequent pollution have been gaining increasing public concern.The unintended exposure to different pollutants,such as heavy metals,air pollutants and organic chemicals,may cause diverse deleterious effects on human bodies,resulting in the incidence and progression of different diseases.The article reviewed the outbreak of environmental pollution-related public health emergencies,the epidemiological evidence on certain pollution-correlated health effects,and the pathological studies on specific pollutant exposure.By recalling the notable historical life-threatening disasters incurred by local chemical pollution,the damning evidence was presented to criminate certain pollutants as the main culprit for the given health issues.The epidemiological data on the prevalence of some common diseases revealed a variety of environmental pollutants to blame,such as endocrine-disrupting chemicals(EDCs),fine particulate matters(PMs)and heavy metals.The retrospection of toxicological studies provided illustrative clues for evaluating ambient pollutant-induced health risks.Overall,environmental pollution,as the hidden culprit,should answer for the increasing public health burden,and more efforts are highly encouraged to strive to explore the cause-and-effect relationships through extensive epidemiological and pathological studies. 展开更多
