食品中化学残留物的风险评估与管理
摘 要
食品中化学残留物的风险评估与管理是保障食品安全的重要环节。随着现代农业和食品工业的快速发展,农药、兽药及其他化学添加剂的使用日益广泛,导致食品中化学残留物的种类和浓度不断增加,对公众健康构成潜在威胁。本研究旨在通过系统性分析和定量风险评估方法,探讨食品中常见化学残留物的暴露水平及其对人体健康的潜在影响。研究选取了中国市场上常见的蔬菜、水果、肉类和水产品作为研究对象,采用高效液相色谱-质谱联用技术(HPLC-MS/MS)进行残留物检测,并结合蒙特卡洛模拟方法评估不同人群的暴露风险。结果表明,部分食品中的化学残留物浓度超过了国际安全标准,尤其是婴幼儿和孕妇等敏感人群的暴露风险较高。基于此,本研究提出了一套综合性的风险管理策略,包括加强源头控制、优化检测技术、完善法律法规以及提高公众意识等措施。

RISK ASSESSMENT AND MANAGEMENT OF CHEMICAL RESIDUES IN FOOD PRODUCTS
ABSTRACT
The risk assessment and management of chemical residues in food is an important link to ensure food safety. With the rapid development of modern agriculture and food industry, the increasing use of pesticides, veterinary drugs and other chemical additives leads to the increasing types and concentrations of chemical residues in food, posing a potential threat to public health. This study aims to explore the exposure levels of common chemical residues in food products and their potential impact on human health through systematic analysis and quantitative risk assessment methods. Vegetables, fruits, meat, and aquatic products common in the Chinese market were selected as the research ob jects, and high performance liquid chromatography-mass spectrometry (HPLC-HPLC-M S/MS) was used for residue detection, and Monte Carlo simulation was used to assess the exposure risk of different populations. The results showed that the concentration of chemical residues in some foods exceeded the international safety standards, especially in sensitive groups such as infants and pregnant women. Based on this, this study proposes a set of comprehensive risk management strategies, including strengthening source control, optimizing detection technology, improving laws and regulations, and public awareness raising measures.
