Objective To determine the content of BPA in food and assess the health risk of food exposure for the popula- tion in Guangzhou city. Methods The concentration of BPA in food was determined by LC-MS / MS , the BPA exposure and risk assessment was calculated in combination with dietary pattern. Results The BPA content in food ranged from 0. 17 ng / g to 7 ng / g , and the exposure to BPA in food was 1 531. 16 ng or 25. 52 ng / kg · bw · day. Conclusions BPA exposure in food was lower than the international limited dose ( 50 μ g / kg · bw / d ) and the risk level is not of a major concern in Guangzhou City.

Objective To determine the level of bisphenol A(BPA) in animal source foods in Wuhan urban area,investigate dietary pattern,calculate the BPA exposure level via animal source foods,and assess the health risk of exposure to BPA from animal source foods among local residents.Methods 78 samples containing 13 kinds of animal food were randomly selected,and the concentration of BPA was determined by LC-MS.338 people from 180 families were randomly chosen.What they ate in recent three days was reviewed,and the amount of animal source foods intake per capita was analyzed.The average BPA exposure was assessed through the concentration of BPA in the investigated samples and dietary data,and the BPA exposure risk level of the local residents were assessed via animal source foods intake.Results the concentration of BPA in animal source foods was between 0.0 to 11.7 ng/g.The intake of animal source foods was 277.48 g·d-1 per capita in dietary survey data analysis.The average daily intake(ADI) of BPA was 11.38 ng/kg bw/ day,which was obviously lower than the international limited dose(50 μg/kg/d).Conclusions Only micro-amount BPA in the majority of animal source foods in Wuhan could be detected,therefore,this would not affect adversely to the health of the local residents.

The financial crisis in Asia, beginning with pressures on the Thai baht and spreading to other countries in the region, has intensified the interest in impulse-contagion mechanism of financial crisis. In this article, first we discuss speculative attack, which is the main form of external impact to financial crisis. Then we construct the time and spatial contagion frame of financial crisis. Finally we analyze the general contagion mechanism of financial crisis systematically.
