Selling empty pesticide packaging to reuse/recycling business has been increased in all over the country. Subject to the resource conservation and global climate change, this could be defined as sustainable or green consumption for the most beneficial use of natural resources. However, on the point of environmental and public health, this is the way to disperse harmfulness of pesticide into non-target areas. Human and environmental health risk of exposure due to pesticide residue in such packaging waste could be a co-incident. This paper was aimed to determine a practical model for pesticide packaging waste management appropriate for Thailand based on the context of country＇s circumstances and the best practices reported around the world. Establishing some necessary components has been proposed, i.e. multiple rinse method applied by farmers conscientiously, central collecting site driven by local community, waste recovery program offered by pesticide production enterprises, and sanitary glass bottle washing plant registration and regulations launched by the government. In conclusion, governmental initiative and all stakeholders including in pesticide packaging waste supply chain should be encouraged to contribute their participation towards sustainable management.展开更多

The original combination patterns of all the units which illuminate the changes from stable state to destroyed state are given. All these patterns can direct the earthquake prediction practice in this region.展开更多

Through the analysis, the possible impacts of extreme space weather on the future ultra-high voltage （UHV） grid, the security of large-scale power system in China are expounded, and the research suggestions coping with the strong solar storms are proposed.展开更多
