Modelling anthropogenic deposits in 3D geological models
-
While geological models traditionally focus on the natural status of the underground, the shallow subsurface has been significantly altered by human activities over centuries. Particularly in urban contexts, ground has been raised, reworked, filled-in or disturbed in other ways. The rationale behind these alterations is as varied as the characteristics of the associated anthropogenic deposits: large-scale structures such as residential and industrial areas built on extensive sheets of filling materials or reclaimed lands are intertwined with smaller-scale features related, for example, to road and railway infrastructures, dikes or landfills. Their composition is equally diverse, ranging from displaced natural materials, such as crushed rocks, gravel, sand or clay, to artificial substances like recycled steel slags, concrete or rubble, or mixtures of these. Gaining knowledge on the presence and characteristics of such deposits is highly relevant, as their physical and chemical behaviour may differ significantly from those of natural deposits. The significance of anthropogenic deposits is increasingly recognized in urban geology. Resolving the geometry and properties of the urban shallow subsurface is essential for anticipating associated risks, for example dealing with pollution, ground stability or distorted water infiltration patterns. Anthropogenic deposits are, however, often scantily archived in permit documentation or represented on (geological) maps. Within the GSEU (Geological Service for Europe) project, the GSB is contributing to the task to develop a common, international vocabulary to describe all aspects of anthropogenic deposits, allowing standardised representation and characterisation in geological models. In parallel, VITO is developing shallow subsurface urban models for the Flemish government (VPO) within the VLAKO-framework, such as the published model of the Antwerp harbour and city. As the anthropogene inherently is part of these models, we are always aiming to better incorporate these deposits into the models. However, modelling the anthropogene presents unique challenges due to its high-resolution variability, scarcity of input data, and dynamic nature. It requires an approach that differs radically from traditional geological modelling techniques, in which depositional concepts related to the sedimentational or structural environment can be incorporated. In this presentation we will outline how we integrate various 1D, 2D and 3D sources to identify and characterize anthropogenic deposits and incorporate these insights in a 3D geological model of the anthropogene. This methodology is applied to the urban periphery of Brussels, where a new 3D geological model is being developed to support infrastructure projects and urban planning with special focus on the ring road (R0) of Brussels. Secondly, we will evaluate current lithological standards, vocabulary and stratigraphic approaches to characterize anthropogenic deposits. We will discuss their applicability in Flanders with practical examples from the periphery of Brussels. Ultimately, improving the representation of the anthropogene in geological models will significantly enhance their utility for urban planning, environmental management, and the sustainable utilization of the subsurface in urban areas.

Molecular methods for the detection and identification of parasitoids within larval wheat midges
-
Three species of cecidomyiid midges (Diptera: Cecidomyiidae) cause significant yield losses on wheat in Europe: Sitodiplosis mosellana (Géhin), Contarinia tritici (Kirby) and Haplodiplosis marginata (von Roser). Eggs and young larvae may be parasitised by a complex of hymenopteran parasitoids belonging to the Pteromalidae and Platygastridae families which contributes to natural pest control. We have developed molecular tools for detecting and identifying seven parasitoid species previously encountered in Belgium inside individual wheat midge larvae. Barcode DNA sequences from COI, 18S and 28S genes were obtained from the midges and parasitoid species. Each of the three genes allowed all the species to be distinguished although 18S was the only one displaying a barcoding gap, both between parasitoids and midges, and at the species level. Based on the 18S gene, we developed a TaqMan assay to assess parasitism in midge larvae, regardless of the midge and parasitoid species. Next, two group-specific PCR primer pairs were generated, allowing the separate amplification of midge DNA or parasitoid DNA in parasitised individuals and subsequent identification by Sanger sequencing. Finally, species-specific primers were designed to identify six parasitoid species by simple PCR amplification. These tools were successfully applied to assess the parasitism rate of S. mosellana larvae in seven Belgian fields.

Monitoring the trade in exotic animal products through DNA barcoding of passenger-imported meat
-
The INTERCEPT-project seeks to propose a robust framework for the long-term monitoring of (exotic) animal product imports into Belgium, highlighting the legal and illegal aspects of the trade and its implications for public and animal health. INTERCEPT aims to move towards a centralised database by integrating data from various federal services and agencies to gain a better overview of the trade and to promote the dissemination of crucial information among federal services, agencies, and stakeholders. The project also aims to introduce a secure and efficient sampling method for officials, along with a laboratory species identification pipeline by researchers, which will enable rapid DNA-based identification of illegally imported meat. During the project, meat intercepted from passengers luggage at Brussels Airport is sampled, identified using DNA barcoding and screened for pathogens. At present, 424 specimens have been sampled, of which 315 have been identified so far. About 40% were derived from non-domesticated species, including meat from 10 CITES-listed species. Among the seized wild meat samples, greater cane rat (Thryonomys swinderianus) and African brush-tailed porcupine (Atherurus africanus) were predominant. Six specimens (5%) were misidentified as domestic meat upon seizure, while DNA analyses revealed a wild species. Inversely, twelve specimens (6%) were misidentified as wild meat, while DNA analyses revealed a domestic species. By fostering collaboration among scientific institutions and federal agencies, this initiative aims to inform border control measures, and will support future research into diseases carried by both domestic and exotic meat, allowing better characterisation of the health risks associated with the illegal import of meat from third countries.

Monitoring the wild meat trade through DNA barcoding and pathogen screening of passenger-imported meat
-
The INTERCEPT project maps the current situation of monitoring (exotic) animal product imports from third countries into Belgium, highlighting both the legal and illegal aspects of the trade and its implications for public and animal health. Recommendations are being drafted to move towards a more robust framework for long-term monitoring including a centralized database that integrates data from various federal services and agencies to gain a better overview of the trade and to promote the dissemination of crucial information among federal services, agencies, and stakeholders. The project also aims to introduce a secure and efficient sampling method for officials, along with a molecular species identification pipeline for researchers, which will enable rapid DNA-based identification of illegally imported meat. During this project, over 600 specimens have been sampled from intercepted meat from passenger’s luggage at Brussels Airport, of which more than 500 samples have so far been identified using DNA barcoding and screened for orthopoxviruses. Metagenomic DNA and RNA sequencing is ongoing for a selection of samples pooled per DNA-confirmed species, preparation method (raw vs. cooked), and, when possible, region of origin. By fostering collaboration among scientific institutions and federal agencies, this initiative aims to inform border control measures and will support future research into pathogens carried by both domestic and exotic meat, allowing better characterisation of the health risks associated with the illegal import of meat from third countries.
