Abstract
Bees play a crucial role in maintaining ecological balance, contributing to biodiversity through pollination and significantly enhancing the agricultural productivity of various crops. However, the frequent use of pesticides in agriculture and surrounding areas has adversely affected the well-being of these essential pollinators. This study focuses on developing a miniaturized method for determining imidacloprid and thiamethoxam in stingless bee Tetragonisca angustula and the foraged pollen from their hives, with subsequent application to environmental samples. This approach efficiently monitors neonicotinoid levels in these matrices by significantly reducing sample mass and reagent usage. During method application, no thiamethoxam was detected, while residual levels of imidacloprid were found in both T. angustula (17.4 to 19.5 ng g−1) and pollen (7.4 to 11.9 ng g−1) samples. These findings highlight the applicability of the developed method for environmental monitoring and reveal the bioavailability of imidacloprid in hives near crop fields, contributing to the assessment of pesticide risk for these non-target organisms.
蜜蜂在维持生态平衡、通过传粉促进生物多样性和显著提高各种作物的农业生产力方面发挥着至关重要的作用。然而，农业和周边地区频繁使用农药对这些重要传粉媒介的健康产生了不利影响。本研究旨在建立一种小型方法，用于测定无刺蜜蜂及其蜂箱花粉中吡虫啉和噻虫嗪的含量，并将其应用于环境样品中。这种方法通过显著减少样品质量和试剂使用，有效地监测这些基质中的新烟碱水平。在方法应用过程中，未检测到噻虫嗪，而在家鼠（17.4 ~ 19.5 ng g−1）和花粉（7.4 ~ 11.9 ng g−1）样品中均发现吡虫啉残留。这些发现突出了所开发方法在环境监测中的适用性，揭示了吡虫啉在农田附近蜂箱中的生物利用度，有助于评估这些非目标生物的农药风险。
期刊介绍：
Water, Air, & Soil Pollution is an international, interdisciplinary journal on all aspects of pollution and solutions to pollution in the biosphere. This includes chemical, physical and biological processes affecting flora, fauna, water, air and soil in relation to environmental pollution. Because of its scope, the subject areas are diverse and include all aspects of pollution sources, transport, deposition, accumulation, acid precipitation, atmospheric pollution, metals, aquatic pollution including marine pollution and ground water, waste water, pesticides, soil pollution, sewage, sediment pollution, forestry pollution, effects of pollutants on humans, vegetation, fish, aquatic species, micro-organisms, and animals, environmental and molecular toxicology applied to pollution research, biosensors, global and climate change, ecological implications of pollution and pollution models. Water, Air, & Soil Pollution also publishes manuscripts on novel methods used in the study of environmental pollutants, environmental toxicology, environmental biology, novel environmental engineering related to pollution, biodiversity as influenced by pollution, novel environmental biotechnology as applied to pollution (e.g. bioremediation), environmental modelling and biorestoration of polluted environments.
Articles should not be submitted that are of local interest only and do not advance international knowledge in environmental pollution and solutions to pollution. Articles that simply replicate known knowledge or techniques while researching a local pollution problem will normally be rejected without review. Submitted articles must have up-to-date references, employ the correct experimental replication and statistical analysis, where needed and contain a significant contribution to new knowledge. The publishing and editorial team sincerely appreciate your cooperation.
Water, Air, & Soil Pollution publishes research papers; review articles; mini-reviews; and book reviews.
