Objective To understand and master the dynamic changes and contributing factors to Guangxi rural drinking water quality. Methods No less than 25% of counties in Guangxi Zhuang Autonomous Region were randomly selected according to the proportional stratified sampling method to build the monitoring network for the dynamic monitoring of rural drinking water quality. The sampling time was arranged in the rainy (July or August) and dry season (March or November) in 2007 and 2008, respectively. The test methods were those documented in the standard (GB 5750-2006). Results The coverage rate of rural centralized water supply was 35.72% in 2008, higher than that in 2007 (31.80%) by 3.92%; the eligible rate of water quality in 2007 and 2008 were 20.57% and 24.59% respectively. The eligible rate of water quality in dry season was higher compared with that in the rainy season. Among all the monitoring indexes, the microbiological index ranked the lowest in terms of eligible rate, ranging from 34.76% to 80.68% for central water systems, and from 21.43% to 66.57% for non-central water supply. Conclusion Microbiological pollution is the main influencing factor for drinking water quality in rural areas in Guangxi Zhuang Autonomous Region.

Objective To know the environmental lead pollution status of rural areas around the mining area in Guangxi,2008.Methods From August to December,2008,the survey was carried out in 28 villages of 4 counties,which were located in basin of three rivers and their tributaries.Six lead-zinc-tin mines were situated in the investigated area.The local samples were collected,including 101 rice samples,30 paddy samples,59 vegetable samples and 45 samples of meat,viscera of poultry,5 fish samples,and 27 surface water samples,12 ground water samples,13 drinking water samples,29 cropland soil samples.The lead content of them were determined,the dietary survey on lead intake was performed among the residents living near the mining area also.Results 53.68%(102/190) of the crop samples revealed higher lead contents,which were over the standard limit,especially for rice(47.52%) and leafy vegetables(100%).The lead contents for five eggs samples,two peanuts samples and thirteen fresh corns were qualified.36%(102/190)of the samples of meat and viscera of poultry revealed higher lead contents,which were over the standard limit,especially for liver and chicken intestine.The lead intake only through rice and vegetables reached 4.55 mg in one week,which was over the tolerance dose by 0.52 times.Conclusion The lead intake of the residents living near the lead-zinc mining area are mainly from crop and vegetables and poultry.Environmental lead pollution is serious in the investigated area and must be controlled as possible as early.

Objective To know the current situation of drinking water quality and the influencing factors of provided for oneself water supply in rural schools in Guangxi.Methods According to the randomly proportionate stratification (economic,geography and topography etc.),43 and 50 counties were selected in 2007 and 2008 and the monitoring sites from 3 rural schools with provided for oneself water supply facility were taken out based on the proportion of water sources and technical patterns coverage in each county.The survey on water supply technical patterns,water sources and their coverage was conducted.One hundred and thirty,one hundred and fifty-three monitoring sites in rain season (July or August) and dry season (March or November) were monitored separately in 2007 and 2008.The monitoring results of drinking water were assessed according to Sanitary Standards for Drinking Water Quality (GB5749-2006).Results The groundwater was main drinking water source,which were 84.03% and 90.75% in 2007 and 2008.Most of water supply had not any water treatment,which was 75.86% in 2007 and 64.22% in 2008.The qualified rate in rain season (18.02%) was significant lower than dry season (31.80%) (P

Objective To investigate the quality of drinking water produced by safe drinking water projects in rural areas of Guangxi.Methods A survey of water quality was conducted from January to October 2008,in the drinking water projects funded by treasure bonds in 89 counties (cities and districts) of Guangxi.The water samples were collected from waterworks and tap water in dry season (March) and rainy season (July to August),respectively,and evaluated for aesthetic,microbiologic and chemical indexes.Results A total of 1 327 drinking water projects were surveyed.58.25% had a daily output under 100 tons,and only 2.71% had an output over 1 000 tons (enough for 10 000 persons).Only 12.28% adopted comprehensive water treatment process (i.e.coagulation,sedimentation,filtration and disinfection),whereas 62.85% did not provide any treatment.Up to 79.80% had no disinfection equipment and 90% failed to provide effective disinfection.25.21% and 21.48% of finished water,and 25.78% and 20.59% of tap water samples tested up to the standard respectively in the dry season and rainy season.Over 88% of water samples met the aesthetic,chemical and toxicological standards (100% up to standard for chronic,arsenic and fluoride),while 73.16%-80.78% met the standard for bacterial count,30.86%-36.17% for fecal coliforms and 41.86%-47.73% for thermotolerant coliforms.Conclusion The study results indicate that the inadequate supply of safe water,absence of water treatment facilities and poor drinking water quality have represented a potential health risk in Guangxi rural areas.

Laser tweezers Raman spectroscopy ( LTRS ) was used to study the inhibitory effect of indol on staphyloxanthin biosynthesis in Staphylococcus aureus cells and the dynamic changes of this pigment content inside bacterial cells during batch cultivation. The Raman spectra of Staphylococcus aureus cells cultivated for different time and exposed to various doses of indol were acquired. The intensity of 1523 cm-1 band was used for the quantification of staphyloxanthin, in the meantime, the pigment was measured by UV spectrometry. The experimental result showed that an excellent linear relationship existed between the intensities of Raman peak at 1523 cm-1 of bacterial cells and the pigment contents estimated by UV spectrometry, with a correlation coefficient of 0 . 9772 . The spectral data at population level as well as single cell level revealed that indol could inhibit the production of pigment in dose-dependent manner, and the pigment content in bacterial cells incubated with indol decreased by 70%. Under the batch growth condition, the pigment amount in Staphylococcus aureus cells reached the maximum value during the middle exponential growth phase ( 12 h ) and the heterogeneity of pigment content in bacterial cells within certain populations at various time points was relatively small, with RSDs of 39. 2% to 61. 1%. This investigation indicates that LTRS can be served as a reliable method for the analysis of staphyloxanthin content at single cell level.
