种养循环系统中典型有害物质对动物的危害研究进展

Hazards of Typical Hazardous Substances in Crop-Livestock Recycling System to Animals:A Review

种养循环系统是农业生态系统的重要组成部分,循环系统要素健康对于维护生态平衡和保障食品安全至关重要。然而,农药残留、重金属、微/纳米塑料以及抗生素及抗性基因等有害物质在这一系统中的累积和迁移,已成为一个不可忽视的问题,其对生物体的危害效应日益引起关注。众多研究揭示,这些有害物质可通过土壤-植物系统进入食物链,对人类和动物的健康构成潜在威胁。本文综述了当前种养循环系统的主要发展模式以及典型有害物质对动物生理代谢及健康的危害,旨在为开展种养循环系统中有害物质风险评估提供参考。

The crop-livestock recycling system is an important part of agricultural ecosystem,and the health of circulatory system elements is very important for maintaining ecological balance and ensuring food safety.However,the accumulation and migration of hazardous substances such as pesticide residues,heavy metals,micro/nano plastics,antibiotics and resistance genes in this system have become a problem that cannot be ignored,and their harmful effects on organisms have attracted increasing attention.Many studies have revealed that these harmful substances can enter the food chain through the soil-plant system,posing potential threats to human and animal health.This article reviews the main development patterns of the current crop-livestock recycling system and the hazards of typical hazardous substances on the physiological metabolism and health of animals,in order to provide a reference for the risk assessment of hazardous substances in the crop-livestock recycling system.
