摘要
为了探究梅县区果蔬农药残留现状,该研究采用气相色谱法(GC)、高效液相色谱法(HPLC)等检测方法,对梅县区果蔬进行农药残留量检测分析。试验结果表明,大部分果蔬产品的农药残留量在安全范围内,其中蔬菜样品的合格率为93.5%,水果样品的合格率为85.7%。然而,仍有部分果蔬样品的农药残留检出率偏高,且超标情况较为严重。例如:柑橘类水果金柚中毒死蜱检出率最高,为16.1%;浆果类水果草莓中腐霉利检出率最高,为16.7%。令人担忧的是,在所有检出的蔬菜样品中,有10.5%的样品农药残留量超过了1 mg/kg。综上,梅县区大部分水果蔬农药残留量在安全标准范围内,但梅县区地处岭南丘陵地带,气候适宜,导致病虫害繁殖速度快,个别果蔬出现农药使用超标现象。该研究旨在通过对不同种类的果蔬农药残留水平进行评估,以期为食品安全监管提供有力支撑,确保广大民众能够享受到安全、健康的果蔬产品。
In order to explore the current situation of pesticide residues in fruits and vegetables in Meixian,this study used detection methods such as gas chromatography(GC)and high-performance liquid chromatography(HPLC)to detect and analyze pesticide residues in fruits and vegetables in Meixian.The experimental results show that the pesticide residues in most fruit and vegetable products in Meixian District are within the safe range,with a qualification rate of 93.5%for vegetable samples and 85.7%for fruit samples.However,there are still some fruit and vegetable samples with high pesticide residue detection rates,and the situation of exceeding the standard is relatively serious.For example,the detection rate of chlorpyrifos poisoning in Meizhou pomelo is the highest,at 16.1%;The detection rate of Fusarium oxysporum in strawberries is the highest,at 16.7%.It is concerning that 10.5%of all detected vegetable samples have pesticide residues exceeding 1 mg/kg.In summary,the pesticide residues in most fruits and vegetables in Meixian district are within the safety standard range.However,Meixian district is located in the hilly area of Lingnan and has a suitable climate,which leads to a fast reproduction rate of diseases and pests,and some fruits and vegetables have exceeded the pesticide usage limit.This study aims to evaluate the levels of pesticide residues in different types of fruits and vegetables,in order to provide strong support for food safety supervision and to ensure that the general public can enjoy safe and healthy fruit and vegetable products.
