The investigation area was divided into 5 zones as industrial zone, inner commercial, inner residence, Traffic Area, Park and Plaza, the soil and plants sample was collected according the Uniform distribution principle with GPS. The content of Cd in soil and plants was detected by ABS. The study showed that Cd concentration in soil was accumulated at a high level, the lowest is 3.38mg/kg and the highest is 8.32mg/kg, the soil is polluted severely, its content is more than III standard. Different area has different Cd content: industrial zone is the highest, 6.98mg/kg is at the top, Park and Plaza is at the lowest, the difference in the concentration is not very great, the city's pollution has been fairly well-distributed. The physics and chemistry characteristics of soil, such as pH, CEC and organic matter are the factors that influence the Cd concentration. The study showed that only pH has the significantly correlation with Cd concentration. Other rationalized in the Cd in the concentration is not obvious relevance. Cd concentration in plants is 0.53-0.84mg/kg. The positive relationship is significant between soil and plants about the Cd concentration.","PeriodicalId":6374,"journal":{"name":"2012 International Conference on Biomedical Engineering and Biotechnology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74220538","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper conducts research of spatial distribution of organic and inorganic carbon contents in sediments of Tai lake in China based on the data of geochemical survey in the early 2000s. Results show that the organic, inorganic carbon contents in surface sediments (0-20 cm) of the lake are 5.76±4.38, 1.42±1.40 g kg-1 and those in deep sediments (160-180 cm) are 2.30±1.39, 2.30±1.39 g kg-1, respectively. The organic carbon content in deep sediments is close to that in surface sediments, but inorganic carbon content is 1.62 times of that in surface sediments. The ranges and coefficients of variation of carbon contents in deep sediments show lower spatial variability due to limited human activity. This work provides valuable information regarding accurate distribution of organic and inorganic carbon in the surface and deep sediments of Tai lake, which may be useful to evaluate intrinsic pollution in the lake.","PeriodicalId":6374,"journal":{"name":"2012 International Conference on Biomedical Engineering and Biotechnology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73334713","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
