摘要
目的,本文通过对市面上流通的竹木餐具进行检测分析,并参照相关国际标准与国标对检测结果进行分析,以评估国内竹木餐具的风险状况,为建立风险防范措施及优化现行标准提供理论依据。方法,本次监测通过二氧化硫、甲醛迁移量、三氯苯酚、五氯苯酚、溴硝醇五项指标(其中二氧化硫为国标,后四项为欧盟参考标准),对全国范围内的600批次样品进行风险分析,主要涉及理化、光谱和液相三个领域。结果,本次监测共发现问题样品13批次,问题发现率为2.2%。其中,二氧化硫问题11批次,甲醛问题2批次。二氧化硫最高检出值达1955 mg/kg,约标准要求600 mg/kg的3.3倍;甲醛迁移量最高检出值为55 mg/kg约为参考限值15 mg/kg的3.6倍。结论,国内市面上流通的竹木餐具存在二氧化硫和甲醛迁移量超标的问题,可能对消费者的健康造成不良影响。其中,二氧化硫属于严重超标,应该引起我们重视。
The purpose of this study is to evaluate the risk status of bamboo and wood tableware in China through the analysis of the test results of bamboo and wood tableware circulating on the market,and the analysis of the test results according to the relevant international and national standards.Also,this study provides theoretical basis for establishing risk prevention measures and optimizing current standards.Method:The monitoring was tested by five indicators:sulphur dioxide,formaldehyde emissions,trichlorophenol,pentachlorophenol and bromonitron.(sulfur dioxide is the national standard,the last four are the reference standards of the European Union).This risk analysis has 600 batches of samples nationwide,mainly including three fields:physicochemical,optical spectroscopy and liquid phases.Result:The monitoring found 13 batches of problem samples,the problem detection rate is 2.2.Among them,sulfur dioxide problem 11 batches,formaldehyde problem 2 batches.A maximum detection of sulphur dioxide is 1955mg/kg,which is 3.3 times than standard requirement.A maximum detection value of formaldehyde is 55 mg/kg,3.6 times than limited reference 15mg/kg.Conclusion:The excess of sulfur dioxide and formaldehyde in bamboo and wood tableware circulating in the domestic market may have harmful effects on consumers'health.Sulfur dioxide is a serious exceeding the standard,which should be paid attention to.
