Survey on Radon Level, Environment and Workers Health in Greenhouse in Lanzhou (Education Papers posted on May 21st, 2015 )

OBJECTIVES①To investigate radon level and its affecting factors in greenhouse in suburb of Lanzhou, and then estimate the annual effective dose exposed to radon absorbed by growers. It was expected to provide measures for controlling indoor radon pollution.②To investigate indoor ambient in greenhouses and its effect on the Health of greenhouse workers in Lanzhou.METHODS 1 Spot investigation:①Three greenhouses were chosen to detect indoor temperature, relative humidity and radon concentrations by Model 1027 type radon monitor during nearly three months.②Two greenhouses were chosen randomly to detect indoor temperature, relative humidity, CO2 and NH3 concentrations during nearly three months. 2 Questionnaire: a questionnaire was carried out for 120 greenhouse workers and 100 controls to clarify the possible correlation between the greenhouse ambient and the workers Health.RESULTS 1 Spot investigation:①An average radon concentration of 132.77 Bq/ m3 in local greenhouses was observed, which is 3.38 and 5.60 times higher than local average indoor radon level and country average indoor radon level, respectively. Soils and rocks under and around the greenhouse as well as wall body are main source of indoor radon. High temperature and low humidity probably facilitated the movement of radon into greenhouses. Meanwhile, a diurnal fluctuation in indoor radon concentration was observed. Furthermore, the annual effective dose exposed to radon absorbed by growers was estimated. Thus, the results showed that growers in greenhouses absorbed much higher effective dose than other residents.②The indoor concentrations of CO2 and NH3 were 0.20±0.02% (0.15~0.24%) and 0.65±0.45mg/m3 (0.05~1.50 mg/m3), respectively. Higher indoor humidity and temperature differences were also observed. 2 Questionnaire: The greenhouse ambient has many adverse effects on joints, eyes and respiration for long-term growers.CONCLUSIONS①High radon exposure is probably potential Health risk ifconsidering combined effects of other adverse Environmental factors in greenhouses.②Higher ammonia level is observed in greenhouses besides temperature andhumidity. More attention should be focused on negative impact of greenhouseambient on growers health.

Comparison of Socio-Economic and Health Status of urban Residents in Chengdu (Education Papers posted on March 21st, 2015 )

Great achievements have been made in Economic and Social development in China over the past two decades. The living standard of the population has been improved remarkably. However, the income gap among different population groups has been widened in the same time. In 2005, the Gini Coefficient of income distribution of Chinese citizens has reached 0.45 which exceeds the alarming line of 0.4 being recommended worldwide. At present, urban poverty has become more prominent due to the great impact resulting from the transformation of Economic system in China. According to the report of Asia Development Bank, the Health condition of the poor urban citizens is generally worse than the general as a result of poor income and low consumption rates; the availability of Medical service for the poor urban citizens is lower than that for medium- and high-income urban inhabitants. All these problems are harmful for the overall improvements of the whole Health level. The problem of urban poverty has become an urgent challenge to the development of Chinese cities. It not only relates to the Social justice, but also affects the Social stability. There are lots of studies on the problem of poverty, with the focus on the definition of poverty, the identificaton of poverty standard and poverty line, the causation of poverty, the living condition of poor people, and the mechanism and strategies of poverty assistance. However, few studies paid attention to the study of health condition of poor urban people and the related influencing factors. The study on health condition of poor people and the availability of Medical service mainly concentrate in rural countries. With sponsorship of the project of Urban Community Health and Poverty supported

Research Objectives:This study described the Basic situation and Health status of Zhuzhou through the investigation, set the expected target of index system using the benchmarking method, identified key areas and projects of the construction, provided the evidence base for the design of Zhuzhou’s Health action outline; Based on the research of the Zhuzhou’s action outline making process, we explored and established a healthy urban action program formulation process, which can provide experience for other cities to develop health action outline for reference.Specific purposes are as follows:1、Analysis on the Basic Economic and Social health situation of Zhuzhou;2、 Analysis and determine the index system of the urban plan;3、 Analysis the surveyed data, to obtain the Basic value of the indexes;4、 Develop guidelines of healthy city for action in Zhuzhou.Data Resources and Methods:Data of this study include three components:1. Some data of this study was from family questionnaire for Zhuzhou to create a healthy city urban plan, the contents including:socioeconomic characteristics of the population; health status, physical examination and doctors’ visiting because of illness; smoking, alcohol consumption, exercise and other health related behavior. The field survey was done in August2012in Zhuzhou’s four areas, a total of1000households using household interview method and received997valid questionnaires.2. Some other data was from institute statistics of Zhuzhou, such as department of health, the center for disease control and prevention, family planning and other departments. We extracted some data from the institutional ones, as baseline value of this index system.3. Literatures. This study searched Google scholar using healthy city, goal setting and priority setting as subject terms for English literature, searched CNKI for Chinese literature using healthy city as subject term, and acquired lots of documents and materials.In this study, we adopted the surveyed method of households and institutions, in addition, we also adopted in-depth interview method, literature research method and expert consulting method.Main Results:1) Analysis the basic Economic and Social situation and health status in Zhuzhou. Through analysis the basic situation of Zhuzhou, we found Zhuzhou’s Economic development in forefront of Hunan province, the overall health level was higher than Hunan and national level; In recent years, through the efforts, Zhuzhou’s environment was also improved; The surveyed data shew that residents’ life behavior had large room for improvement. Zhuzhou’s health city construction will focus on improving the urban environment and advocating the good way of life behavior.2) Zhuzhou’s action outline of healthy city index system was developed. We constructed the indicator system by applying the method of literature research and expert consultation, combined with the availability and accuracy of the indexes, the feasibility of data collection, and predictability of indexes, ultimately determined index system included:11measures of economic and social environment such as “town dweller lowest life to ensure standard”,4measures of policy Management such as “cooperation of departments”,6measures of health indicators such as “average life expectancy”,9measures of health services such as “sports facilities per capita land area”,6measures of public opinion such as “civil satisfaction with public security”. There were a total of36indicators which fell into five categories.3) Analyzed the surveyed data and agencies” data, obtained the indexes” baseline values.”Town dweller lowest life to ensure standard” in2011was15%of wage standard, the rate of urban living garbage hazard-free treatment was100%, the rate of urban sewage concentrated was85%, and other indicators” baseline values from the index system. 4) Created a healthy city’s action outline (2012-2020) in Zhuzhou. This study adopted the method of benchmarking, with reference to healthy city index standards’ requirements, combined with the actual situation of Zhuzhou, set the healthy city index targets; Compared the indicators’baseline values and the expected targets, according to the multiple criteria decision analysis method, we sorted the existing problems, finally determined3tasks including “improving health environment”,”popularization of healthy life style” and “the task of building a healthy society”; Then we established powerful safeguard measures, the government as leader, coordination of departments, clearing each responsibilities, increasing government Investment, and etc.Conclusions:This paper studied the process of established Zhuzhou’s health city action outline, analysed the whole process. In the beginning of this study we decided to find current problems we were facing in Zhuzhou through analysis the basic situation, find the focus of health city construction; We constructed the index system of Zhuzhou healthy city using the literature research and expert consultation method, rather than Delphi method, so the scientific nature, the feasibility and reliability of index system need to be further verified; When using questionnaire and data we found that some data was missing or updated slowly, so it is necessary to set up health information Management system; This study also summarized the methods of setting goals and priority setting and we set target values of indexes and key areas scientifically, also we made the powerful safeguard measures.Suggestions:1) We should understand the health status of the city through field research and baseline data collection, which can provide evidence for setting appropriate expected targets;2) Set up a management system of health information, build a healthy city index system using scientific method, assess and update it regularly;3) Set a reasonable expected targets based on country’s requirements, combined with local actual situation;4) Using scientific methods to determine the priority in the construction field, formulate and improve relevant policies and priorities in the field of action items;5) Develop powerful safeguard measures, such as establish management system, fund input, etc;6) The construction of healthy city is a process, so we need to summarize periodically, step by step.

Comparative Analysis of Soil Microbial Flora of Diffrerent Forests in Tonglu and Tiantai of Zhejiang Province (Education Papers posted on February 25th, 2015 )

Soil microbe as an important component in forest ecosystem,which was used as an indicator to evaluate forest Health, plays an important role in energy flow of soil and progress of material cycle. Therefore, it was significant to investigate the effects of floristic changes in soil microbe of forest on the healthy development of forest ecosystems.In the present study, three woodlands were chosen from Tonglu, Zhejiang Province: Broadleaf forest (sample A), Masson pine-broadleaved mixed forest (sample B), and Masson pine plantation (sample C), and two woodlands were chosen from Tiantai:Masson pine forest (sample D) and Broadleaf forest (sample E), all of which were performed microbiotic comparative analysis. Microflora in 0~50 cm soil layers of aboved 5 woodlands was observed using morphological analysis combined with molecular biology identification. The main results were as followed:1. The results showed that the quantitative proportions of microorganism in 5 forests communities were:Bacteria was the main microbial group, followed by actinomycetes, and eumycete was smallest.2. There were significant differences with a vertical distribution in the quantity of soil microbe, the surface layer of which was significant higher compared to bottom layer, and all the vertical distributions of bacteria, fungi and actinomycetes had a gradually decreasing tendency with the increase of the soil depth.3. There were significant differences of the quantity of soil microbe and distribution of dominant species in different forests and different seasons suggesting that the season, the differences of forest vegetation and edaphic condition were the principal factors to affect the quantity of soil microbe.(1) The comparison of bacteria flora in 5 forests:The quantities of bacteria in 5 forests:There was three significant differences bacteria quantities between sample A and B、C in the surface layer, while no significant difference between sample D and E. There was significant differences bacteria quantities between sample B and A、C, and between sample D and E in the bottom layer, while no significant difference between sample A and C.The quantities of bacteria in the four seasons:in sample A and B germ had the maximum number in winter in two soil horizons. The surface layer of sample C and D, germ had the maximum number in winter and in the bottomsoil layer, the number reached its maximum in fall. In sample E surface layer, the peak of germ number appearred in spring and in bottom layer, it appearred in summer.The dominant species of soil bacteria were Lysinibacillus, Staphylococcus, Burkholderia, Arthrobacter, Paenibacillus, Micrococcus, Pseudomonas and Bacillus.(2) The comparison of fungi flora in 5 forests:The quantities of fungi in 5 forests:There was three significant differences bacteria quantities between sample A and B、C in the surface layer, while significant difference between sample D and E. There was significant differences fungi quantities between sample A and B、C in the bottom layer, while no significant difference between sample A and C, and between sample D and E.The quantities of fungi in the four seasons:in sample A, fungus’number had the maximum number in summer in two soil horizons, and fungus’number had the maximum number in fall in two soil horizons of sample B. The surface layer of sample C, fungus’number had the maximum number in summer and in the bottom soil layer, the number reached its maximum in fall. In sample D, the number reached its maximum in summer in two soil horizons. And in sample E, the fungus’number of two soil horizons reached its maximum in summer.The dominant species of soil fungi included Mortierella, Aspergillus,Penicillium, Trichoderma and Cladosporium.(3) The comparison of actinomycete flora in 5 forests:The quantities of actinomycete in 5 forests:There was significant differences bacteria quantities between sample A and B、C, and between sample D and E in the surface layer, while no significant difference between sample B and C. There was three significant differences actinomycete quantities between sample A and B、C, and between sample D and E. in the bottom layer.The quantities of actinomycete in the four seasons:in sample A, actinomycetes’number had the maximum number in summer in surface layer, while actinomycetes’ number of bottom layer had the maximum number in winter. Actinomycetes’number of sample B,it had the maximum number in winter, while the number reached its maximum in spring in bottom layer. The surface layer of sample C, Actinomycetes’ number had the maximum number in summer and in the bottom soil layer, the number reached its maximum in fall. In sample D, the number reached its maximum in winter. As for bottom layer, it was in sunmmer. And in sample E, the actinomycetes” number of two soil horizons reached its maximum in summer.The dominant species of soil actinomycete were Streptomyces, Nocardia,Micromonospora and Kitasatospora.
