For the purpose of exploring the evaluation model for the SCCIP, a method based on quantitative risk assessment was adopted for evaluating transport risk and to confirm reasonable safety transport capacity of chemical industrial park, and then by combining with the safety storage capacity, a SCCIP evaluation model was put forward. The SCCIP was decided by the smaller one between the largest safety storage capacity and the maximum safety transport capacity, or else, the regional risk of the park will exceed the acceptable level.The developed method was applied to a chemical industrial park in Guangdong province to obtain the maximum safety transport capacity and the SCCIP. The results can be realized in the regional risk control of the park effectively.展开更多

The aim was to determine which faecal DNA field preservation method best enhances PCR amplification success. Samples stored in ethanol showed a significantly higher amplification success of microsat ellite loci than samples stored in the other two media. In contrast, amplification success of a mitochondrial locus was similar among the samples stored in the three types of media. We reviewed twelve previous studies that employed different media for the storage of faeces, although patterns of success were not fully consistent among different media, ethanol storage was scored high est in the majority of these tests展开更多
