The invention discloses a method for determining residual amount of metrafenone. The method is mainly used for determining the residual amount of metrafenone in cereal grains, animal-derived foods and other complex matrix food agricultural products. The method comprises the following steps: homogenizing and extracting residual metrafenone in a sample with acetonitrile or an acetonitrile solution containing 1% of acetic acid, performing purification and concentration by a C18 / PSA solid-phase extraction column, performing gas chromatography-negative chemical ionization-mass spectrometry (GC-NCI-MS) detection, establishing a standard curve for correction by adopting a blank matrix solution without a pesticide to be detected, and quantifying by an external standard method. According to the method, the average recovery rate is 83.9%-90.1%, the average relative standard deviation (RSD) is 4.0%-5.8%, the detection limit is lower than 0.67mu g / kg, and the method has the advantages of simplicity and convenience in operation, high speed, good impurity removal effect, high sensitivity, strong characteristic feature, good repeatability and accurate qualitative and quantitative properties. According to the method, the technical requirements on safety detection of corresponding products in European Union, United States, South Korea, Japan and other countries can be met, and a powerful technical support is provided for ensuring food safety of people in China and health development of export trades.

The invention discloses a sterilization rubber floor, which comprises a top layer and a bottom later, wherein the top layer and the bottom layer are mutually connected; the top layer is made of rubber which is formed by the following materials in parts by mass: 100 parts of oil-extended styrene butadiene rubber, 5-8 parts of zinc oxide, 1-3 parts of stearic acid, 2-4 parts of sulphur, 40-65 parts of furnace black N330, 1-4 parts of N-tertiary butyl-2-benzothiazole sulfonamide, 2-3 parts of metrafenone and 1-2 parts of bupirimate.
