摘要

在整个欧洲,欧洲野兔(Lepus europaeus)的数量一直在下降。这被认为是由于工业化农业的集约化和本地生物群落的丧失。接触杀虫剂也被认为是繁殖减少和人口减少的一个原因。本研究的目的是评估在丹麦的欧洲野兔中发现的杀虫剂的浓度和种类。采用多残留和特异制样方法,分别采用LC-MS/MS和GC-MS/MS对48份肺样品、51份毛皮样品、54份尿液样品和100份肝脏样品进行分析。在这些样本中检测到32种农药/代谢物:皮毛20种,尿液12种,肝脏11种,肺部5种。皮毛中检出最多的农药是戊康唑、苯硫胺和灭虫威,尿液中检出最多的农药是除草剂草甘膦及其代谢物AMPA和苯硫胺,肝脏中检出最多的农药是甲芬酮。肺样本中最常发现的农药是螺虫体-烯醇葡萄糖苷,螺虫体的代谢物,尽管它只存在于少数野兔中(6%)。检出的农药几何均值均在100 μg/kg以下:皮毛(4.59 ~ 67.4 μg/kg)、尿液(4.79 ~ 195 μg/mL)、肝脏(5.58 ~ 85.8 μg/kg)、肺部(8.35 ~ 26.6 μg/kg)。毛皮中杀虫剂的绝对数量很高,表明接触了新喷洒的田地。虽然农药的浓度普遍较低,但不能排除农药与其他环境挑战共同作用,因此从长远来看可能对野兔的生理和寿命产生影响。

Exposure of European hares (Lepus europaeus) to pesticides in Danish agricultural areas

Exposure of European hares (Lepus europaeus) to pesticides in Danish agricultural areas

Exposure of European hares (Lepus europaeus) to pesticides in Danish agricultural areas
There has been a decline in the population of European hare (Lepus europaeus) throughout Europe. This is considered to be due to the intensified industrial agriculture and the loss of native biotopes. Exposure to pesticides has also been mentioned as a reason for reduced reproduction and population decline. The objective of this study was to assess the concentrations and types of pesticides found in European hares in Denmark. A total of 48 lung samples, 51 pelt samples, 54 urine samples, and 100 liver samples were analyzed using multi-residue and specific sample preparation methods, followed by LC-MS/MS and GC-MS/MS. In these samples, 32 pesticides/metabolites were detected: 20 in pelt, 12 in urine, 11 in liver, and five in lung. The most frequently detected pesticides in the pelt were tebuconazole, boscalid, and prosulfocarb, in urine it was the herbicide glyphosate, its metabolite AMPA, and boscalid, and in the liver the most frequently detected pesticide was metrafenone. The most frequently found pesticide in lung samples was spirotetramat-enol glucoside, a metabolite of spirotetramat, though it was present in only a few hares (6 %). Geometric means of detected pesticides were generally below 100 μg/kg: in pelt (4.59–67.4 μg/kg), in urine (4.79–195 μg/mL), in liver (5.58–85.8 μg/kg), and in lung (8.35–26.6 μg/kg). The high absolute number of pesticides in the pelt suggests exposure through contact with newly sprayed fields. Although concentrations of pesticides were generally low, it cannot be excluded that pesticides act additively in combination to other environmental challenges and thereby in the long run may have an effect on the physiology and life span of hares.

期刊介绍: Environmental Pollution is an international peer-reviewed journal that publishes high-quality research papers and review articles covering all aspects of environmental pollution and its impacts on ecosystems and human health. Subject areas include, but are not limited to: • Sources and occurrences of pollutants that are clearly defined and measured in environmental compartments, food and food-related items, and human bodies; • Interlinks between contaminant exposure and biological, ecological, and human health effects, including those of climate change; • Contaminants of emerging concerns (including but not limited to antibiotic resistant microorganisms or genes, microplastics/nanoplastics, electronic wastes, light, and noise) and/or their biological, ecological, or human health effects; • Laboratory and field studies on the remediation/mitigation of environmental pollution via new techniques and with clear links to biological, ecological, or human health effects; • Modeling of pollution processes, patterns, or trends that is of clear environmental and/or human health interest; • New techniques that measure and examine environmental occurrences, transport, behavior, and effects of pollutants within the environment or the laboratory, provided that they can be clearly used to address problems within regional or global environmental compartments.
