“…The polychlorinated biphenyls (PCBs) with a high chlorination degree (congeners 138, 153, and 180) were quantifiable, in comparable concentrations in all three samples. These results correspond with the prevailing contamination of bats with POPs like PCBs, DDE, or lindane that has previously been shown in bat liver samples, despite their prohibition decades ago [ 60 ].…”

Bats are the second largest mammalian order and are an endangered species group with a strong need for contamination monitoring. To facilitate non-invasive monitoring of the ecological burden in bat populations, a multiresidue method for the simultaneous quantification of 119 analytes including pesticides, persistent organic pollutants (POPs), active pharmaceutical ingredients (APIs), polycyclic aromatic hydrocarbons (PAHs), UV blockers, plasticizers, and other emerging pollutants in bat guano with gas chromatography tandem mass spectrometry (GC-MS/MS) was developed. Sample preparation and clean-up were performed with a modified QuEChERS approach based on DIN EN 15662. The method uses 1.00 g bat guano as sample with acetonitrile and water for liquid-liquid extraction. Phase separation is assisted by citrate-buffered salting out agent. For clean-up of the extract, primary secondary amine (PSA) was combined with graphitized carbon black (GCB). The lower limits of quantification (LLOQ) ranged between 2.5 and 250 µg kg−1. Linearity was shown in a concentration range from the respective LLOQs to 1250 µg kg−1. The median of the mean recovery was 102.4%. Precision was tested at three concentrations. Method and injection precision were adequate with a relative standard deviation (RSD) below 20%. Furthermore, the comparative analysis with LC-MS/MS demonstrated the reliability of the results and provided a valuable extension of the analytical scope. As proof of concept, three guano samples from a German nursery roost of Myotis myotis were analysed. The results show a time-dependent change in contaminant concentration, highlighting the strong need for non-invasive contamination monitoring of whole bat populations. Graphical Abstract

“…Moreover, previous studies have shown that bats are highly exposed to various environmental pollutants, including e.g. heavy metals, organochlorine contaminants, parabens and pesticides, and bat guano is an appropriate matrix for such studies [71][72][73].…”

“…blood, urine, tissues, hair), that require animals to be captured or killed, feces samples may be gathered without significantly interfering with animal's life. Moreover, previous studies have indicated that bat guano may be an appropriate matrix to study the exposure of this animal group to various substances polluting the natural environment, such as parabens, pesticides and heavy metals [71][72][73]. Undoubtedly guano analysis also has its drawbacks such as impossibility to assign samples to certain animals, and therefore the animal's age, sex, and health status cannot be determined, and these parameters often affect the degree of exposure to environmental pollutants [98,99].…”

Benzophenones (BPs) are substances used in the production of sunscreens, cosmetics, and personal care products. However, there is a lack of knowledge of BPs in wild animals. Therefore, the study aimed to assess the concentration of selected BPs commonly used in the cosmetic industry in guano samples collected from 4 colonies of greater mouse-eared bats (Myotis myotis). Liquid chromatography with tandem mass spectrometry (LC-MS/MS) was used to determine guano concentrations of benzophenone 1 (BP-1), benzophenone 2 (BP-2), benzophenone 3 (BP-3) and benzophenone 8 (BP-8). BP-1 levels above the method quantification limit (MQL) were noted in 97.5% of samples and fluctuated from <0.1 ng/g to 259 ng/g (mean 41.50 ng/g, median 34.8). The second most common was BP-3, which fluctuated from <0.1 ng/g to 19 ng/g (mean 6.67 ng/g, median 5.05), and its levels higher than MQL were observed in 40% of samples. BP-2 and BP-8 concentrations did not exceed the method detection limit (0.04 ng/g) in any analyzed sample. There were visible differences in the BP-1 and BP-3 levels among the studied bat colonies. Mean BP-1 concentration fluctuated from 11.23±13.13 ng/g to 76.71±65.51 ng/g and differed significantly between the colonies. Mean BP-3 concentration fluctuated from 5.03±6.03 ng/g to 9.18±7.65 mg/g, but it did not differ significantly between the colonies. The results show that guano is a suitable matrix for the assessment of wildlife exposure to BPs. This could be particularly advantageous in protected species, where not disturbing and stressing the animals are crucial.

The problem of contaminated sites is a hot and difficult issue in global environmental sustainable development. Because the contaminated site carries a large number of harmful substances (heavy metal ions, organic polycyclic aromatic hydrocarbons, toxic gases, etc.), it brings great security risks to the environmental ecological security and people's health. Effective identification of the characteristics of contaminated sites and understanding of the research status and development trend of contaminated sites are of great significance to environmental sustainable development and environmental governance and restoration. Based on Web of Science database, this study systematically, quantitatively and visually analyzes the research status of contaminated sites by bibliometrics and knowledge graph technology. The results show that bibliometrics and knowledge graph are effective in information retrieval and visualization. It can display the information of different scales and different times in the study of contaminated sites, and find the distribution characteristics of popular keywords. The cluster cases of this study show that the problems of contaminated site research mainly focus on suspended particulate matter pollution, water pollution, heavy metal pollution, organic pollution, pollution reduction and bioremediation technology research. In the future, the hot issues of contaminated site remediation and environmental sustainable development will focus on strengthening the research of microbial remediation technology, nanomaterial technology, composite material adsorption technology and so on.
