In response to the international circulation and product standardization of pesticides used in environmental sanitation, this research addressed the formulation specification for environmental sanitation pesticides according to international standard to raise the quality of environmental sanitation pesticides and to assure users’ safety in using pesticides and prevention / treatment effect. This research uses the insecticide formulation and quality norm separately set up by World Health Organization, Food and Agriculture Organization of the United Nations and other international organizations for the basis of usage assessment. This year, 2005, the completed are listed below: 1. Setting up various formulation specification norms for environmental sanitation pesticides for the authorities to base on when executing examinations and registrations of the pesticides as a uniform registration principle. 2. The finished goods formulation list for environmental sanitation pesticides and also the classification examination techniques for solid formulations completed. 3. Setting up formulation specification norm for existing environmental sanitation pesticides and completing the assessment of resources and examination fee of the examination institutes. Shown by research investigation, there are 68 formulations of environmental sanitation pesticides presently in general use; their formulation names, codes and definitions can be used as the norm for application for examination domestically. In order to coordinate with international formulation classification of environmental sanitation pesticides, their formulation morphology and application methods were used for classification, i.e. separated into technical materials and finished goods formulations; while the finished goods preparations were separated into 3 kinds of solid formulation, liquid formulation and special formulation for convenience of organization and application purposes. Found by this research investigation, the resources of domestic examination institutes for environmental sanitation pesticides are insufficient and product formulation specifications are still unable of completely meeting current international specifications; so there are needs in active assistance work in the respects of examination institutes and product formulation specifications. Found through the investigation of willingness in applying for examination into environmental sanitation pesticides, existing examination institutes are mostly unwilling to participate in examination works. The main reasons are lack of equipment , manpower , market, examination method, and policy promotion. So, in establishing formulation norm specifications of environmental sanitation pesticides, development of various examination methods for physical – chemical properties of environmental sanitation pesticides should be listed as the priority of the government.
