Cadmium in agricultural soils,vegetables and rice and potential health risk in vicinity of Dabaoshan Mine in Shaoguan,China

Soil cadmium(Cd)contamination resulted from mining and smelting is a major environmental concern,and health risk associated with Cd exposure to multi-media through muti-pathway is increasing.Cd concentrations in soils,vegetables and paddy rice were investigated,and potential non-carcinogenic and carcinogenic health risks exposure to Cd were estimated at six villages around the Dabaoshan Mine,South China.A total of 87 soil samples were found to exceed the China's maximum permission level(MPL)for Cd,while the highest value of 4.42 mg/kg was found near irrigation ditch associated with Hengshi River in Xinyi(XY)Village.Cd contents in vegetables and rice exceeded the maximum permissible concentration by more than five times in every village.Cadmium accumulation in plants is in the order of celery>lactuca sativa L>Chinese cabbage>Romaine lettuce>asparagus lettuce>mustard>cabbage mustard>cabbage.The mean hazard quotient(HQ)of all villages is in the range of [5.29,25.75],and the mean values of cancer risk for investigated areas are more than 10 times greater than the USEPA(2009)threshold limit value of 10-4.Moreover,human non-carcinogenic and carcinogenic risks are mainly attributable to paddy rice intake,followed by vegetables intake,soil ingestion,inhalation,and dermal contact.The results indicate that Cd has a huge potential risk on human health for the local residents.

Research on Financial Support of New Countryside Construction in China

The cpc＇s 13th Five-Year comprehensive plan put forward a major historic task of building a new socialist countryside. This is the comprehensive implementation of urban and rural development to increase industrial agriculture, move the city to support the countryside, accelerate urbanization and narrow the gap between urban and rural areas. To solve the ＂three rural issues＂, the comprehensive construction ofa well-offsociety, has a very important strategic role to ease the contradiction of China＇s rural and urban ecnomic structure. In the process of building a new socialist countryside, the financial policy, as an important means ofmacroeconomic regulation and control, should play a leading role in solving the effective allocation ＆funds. Due to various factors affected by the current supply of rural financial market constraints, system defects and environmental constraints, there is a large gap between the level of the existing rural financial services and the requirements of the new rural construction which is to be improved urgently.

Pesticide Contamination in Land Reform Settlements in Brazil： Empirical Evidences from Caiaponia, Goias State

Brazil is the largest consumer of pesticides worldwide. Public health studies in Brazil show that inadequate use of pesticides increases the incidence of accidents and contamination of poor rural communities. This study sought to identify factors that determine the occurrence of problems with pesticides in a typical Brazilian land reform settlement. The study was carried out in Caiaponia, Goias state. In the empirical analysis, the econometric model pro bit was used. The dependent variable was the existence of health problems in the family setting that are caused by pesticides. The independent variables were the family size; the attendance to any church, whether Catholic or Protestant; if farmers received any technical assistance; the current health condition of the family, and if there are exacerbated erosion problems on the farm. Data from 28 farmers were collected through a structured questionnaire. Among the main findings, larger families have a higher probability of accidents involving pesticides. The current healthy conditions of family and the problems of soiled gradation in the farm imply are duction in the likelihood of contamination with pesticides. These two results indicate that rural households that have good health condition and have experienced environmental degradation on their farm have higher environmental awareness.

Agriculture Development and Strategy in Scientific Concept of Development

This report presents the party＇ s congress in 2020 to ensure the completion of the goal to achieve a comprehensive well-off society, and build a moderately prosperous society that focuses on rural issues and bottlenecks. After the founding of New China＇ s rural issues, our country has gone through a period of free flow of urban and rural in urban and rural isolation period and the interaction period. Although the performance of the various period＇ s rural issues are not the same, but behind it there is a profound theoretical and practical logic. It is the cumulative long-term history of this issue to become ＂top priority＂ , the scientific concept of development is put forward to solve this problem, which is to expand the boundaries of knowledge, provide methodological guidance for us to solve rural issues. Therefore, to solve three agricultural issues to thoroughly implement the scientific concept of development, we must regard development as the top priority in governing and rejuvenating the party, adhere to the overall planning of urban and rural development, adhere to the overall rural economic and social development,, and adhere to a comprehensive, coordinated and sustainable development.

Pupil＇s Diet-Related Attitudes to Healthy Lifestyle

The main purpose of this article was to find out more about eating habits along with other habits, attitudes and activities of elementary school pupils. Another aim was to determine possible differences among pupils, depending on their sex, age and environment. Furthermore, based on the anthropometric data （body mass and height） and age, this article was to determine the nutritional status of pupils. The research was conducted via questionnaire constructed for the needs of this specific research. Six hundred and fifty-one pupils took part in this questionnaire in a ratio of 41：59 urban/rural and 51：49 girls/boys. Most of the interviewed pupils （73.88%） have normal body mass according to their age. The share of underweight and overweight pupils is bigger among the boys. Nutritional habits differ among pupils from the urban and rural areas, but they do not differ as much among boys and girls. In addition, their nutritional habits become worse as they grow up.

Access to Healthy Food Stores for Residents of Aboriginal Reserves in Rural British Columbia

The rate of food insecurity has increased tremendously over the past decade in Canada. This increase has been more pronounced in rural and remote areas especially among Aboriginal peoples. Substantial studies indicated that nearly half of the on-reserve Aboriginal households in British Columbia （BC） suffer from some degree of food insecurity. Despite the valuable research about obtaining traditional food, the issue of access to market food has been less discussed in the literature. The aim of this study was to assess the local food environment of on-reserve Aboriginal peoples by using a proximity-based approach tool in terms of access to healthy food stores such as supermarket and grocery stores. In the first stage, the addresses of all healthy food stores were geocoded into a map layer. Then the locations of Aboriginal reserves were geocoded to a separate map layer. In the second stage, using ＂Closest Facility Analysis＂ tool in ArcGIS Version 10.3, the distance based on a 15-minute driving time was measured from each reserve to the closest healthy food destination on CanMapRouteLogistics network. The results indicated that 25% of Aboriginal reserves did not have reasonable access to healthy food stores. We concluded that Aboriginal peoples in low access rural reserves with lower socioeconomic status are at potential risk of perpetuate food insecurity.

The Possibility of Agricultural Drainage Water Reuse in Agricultural Project

Agricultural drainage water in Ashkada-Barak agricultural project is a major source of wasted water, which amount to about 35 million liters per day. This huge sum of wasted water cause a formation of pools around the area and therefore a lot of environmental problems such as the proliferation of mosquitoes, and other health problems, while it can be reuse in a variety purposes such as agriculture, fish farming and drinking, so the goal of this research is to study quality of water and determine its suitability. Different samples were taken over a period of year for testing the most important elements of which were estimated concentrations of nitrate, nitrite and ammonia. The results show a presence of high concentrations of nitrogen compounds in studied water. Temperature had been identified as environmental factor dynamically controlled the process of nitrification.

Health and Labor Productivity among Female Farmers in Imo State, Nigeria

This study examined the impact of farmers＇ health on labor data was collected through a field survey of 290 rural households productivity of female farmers in Imo State, Nigeria. Primary Descriptive statistics and estimation of efficiency following maximum likelihood estimation （MLE） procedure available in Frontier 4.1 were used to analyze the data. Results from the analyses showed that malaria has the highest prevalence level among female farmers in the study area followed by typhoid fever. The causes of sicknesses vary from cold, stress, mosquito bites and bad drinking water. Furthermore, the results showed that sicknesses affect the productivity of farmers by reducing their work capacity. Also, the distance to source of drinking water from home, source of drinking water, age, body mass index of farmers are also found to significantly affect the physical work output of farmers in the study area. The result shows that the distribution of farmers was highly skewed with about 99% of the farmers having their efficiency above 0.61. This indicates that majority of the farmers are technically efficient in the allocation of resources to crop production, The result also shows that the average efficiency was about 82.9%. Thus, the farmers＇ level of efficiency can be improved if there is a shift in the fi＇ontier, i.e. if factors contributing to inefficiency are adequately controlled. The study recommends the need to invest more on human capital especially health for there to be an improvement in rural productivity. Also, rural development policies should include health policies especially for women since it has a great influence on the household and emphasis should also be on preventive rather than curative health services.

Analysis Method for Pesticide Residues in Biological Matrices： Gas Chromatography-mass Spectrometry

Pesticides have done a great service to human, but their use is not safe for public health. Apart from pesticides acute toxicity, their chronic toxicity can cause various problems for human health. The objective of this work was to validate a liquid-liquid extraction method, which allows a fairly reliable analysis of pesticides using gas chromatography-spectrometry mass （GC/MS） in toxicology laboratory at National Institute of hygiene, Rabat Morocco. The equipment required to perform these analyzes are the biological matrices （blood, gastric fluid）, in which the authors have doped the Organophosphorus pesticides such as Chlorpyrifos, Dichlorvos and Organochlorine pesticide： dichlorodiphenyltrichloroethane （DDT） and Heptachlor. After extracting the mixture with toluene, the supernatant was collected after centrifugation and concentrated in a small volume of 1.5 mL and then analyzed in GC/MS. After analyzing, the authors found that the yields of each pesticide in samples are significant; respectively they represented 73.4% of Chlorpyrifos, 70.8% of Dichlorvos, 47.8% of DDT and 71.6% of Heptachlor. The blood has a strong link with the most pesticides, where it＇s important to use the GC/MS to identify these products. The extraction with toluene was effective, especially to OP, but it＇s also sensitive to OC.

Evaluation of Pesticide Residues in Mango by a Multi-residue Analysis and GC/MS Triple Quadrupole

Mango fruit has a great national and international market, and Brazilian production is 1,900 thousand tons/year exporting to North America and Europe. However, the loss could occur during the production when it is affected by pests and climate conditions, so the increased use of chemical substances and their presence should be monitored. A task for governmental agencies, producers and food sales, attending the sanitary barriers requirements, is to distribute food free from contaminants, so laboratories involved in this type of work usually employ multi-residues analysis. The objective of this study was to evaluate the presence of pesticide residues in mango using QuEChERS method and mass spectrometry technique. Positive samples were compared with Brazilian maximum residues level （MRL） and the health risk exposure was evaluated using the acute dietary intake （ADI） parameter. A total of 20 samples were collected from January to March, in Sao Paulo city markets. The recoveries were in the range of 70% to 120%, and standard deviation was below 20%. The category of pesticides not permitted for the crop were found in l0 samples; eight samples presented pesticides below MRL and two samples above MRL for the fungicide procloraz. The ADI values were below 20% of ADI for an adult and the worst case was dimethoate with 69% of ADI for children. The time spent in monitoring studies and the viability of method chosen must be considered by pesticide residues laboratories during routine analysis of food quality control.
