Riverbanks are an important source of plastic pollution. However, the current assessment methods for riverbank litter are based on a point-based sampling which is time consuming and limited in scope. To quickly assess hotspot areas and litter compositions in larger areas, this study developed a new citizen science bicycle survey for riverine debris. Covering 281.5 km of the Tamsui river system in Taiwan, the new methodology was tested at one of the most plastics polluted rivers in the world. The results revealed an average litter density of 15.3 m3/km at the river mouth and of 0.2 m3/km to 2.8 m3/km along the riverbanks further upstream. The coastline was mainly polluted by derelict fishing gear whereas single-use plastics and illegally dumped waste dominated the upstream areas. A correlation between litter and population density could not be identified, but it was noted that litter hotspots occur at cut banks and near mangrove vegetation. Overall, the new methodology proved suitable to collect large quantities of data for scientific purposes and to quickly detect litter accumulations prior to clean-up activities.

The microplastic pollution and its effects on ecosystem in the marine environment has been well studied over the past decade. In contrast, the impact of microplastic pollution in freshwater environments was understudied, e.g., only a few studies examined the amount and distribution of microplastic in rivers, as well as the contribution of rivers to the microplastic pollution in oceans. In this study we investigated the microplastic pollution in the Tamsui River and its tributaries in northern Taiwan. We collected samples with a manta net from the Tamsui River, the Dahan River, the Keelung River and the Xindian River every two weeks over a time period of three months in 2018. Additionally, we took samples from the Xindian River during a heavy rain event in February 2019. Microplastic particles in the size range of 0.3–5 mm were visually identified. Unknown particles were identified using FTIR spectroscopy. The extracted particles were counted and classified according to their shape and color. We found microplastic of varying amounts in each of the samples, which indicates a wide spread pollution in the Tamsui River and its tributaries. The amount varies between rivers and ranges in average from 2.5 ± 1.8 particles per m3 in the Xindian River to 83.7 ± 70.8 particles per m3 in the Dahan River. Our data shows a positive correlation between precipitation and amount of microplastic particles found in the rivers. Moreover, in each river we could observe a large spatial and temporal variation of the microplastic amount between the left, middle and right sections of the stream. Due to this heterogeneous distribution of particles, we suggest that samples for microplastic analysis should be taken from multiple places across a river, as well as over a certain period to account for the heterogeneous microplastic distribution in the river water.

Plastic pollution is a rapidly worsening environmental problem, especially in oceanic habitats. Environmental pollution with microplastic particles is also causing food consumed by humans to be increasingly polluted, including table salts. Therefore, we present the first study which focuses only on table salt products purchased in Taiwan which we examined for the presence of microplastics. We used Fourier transform infrared spectroscopy to identify the polymer type of each particle. Within 4.4 kg of salt, we detected 43 microplastic particles which averages to 9.77 microplastic particles/kg. The identified polymer types were, in descending abundance, polypropylene, polyethylene, polystyrene, polyester, polyetherimide, polyethylene terephthalate, and polyoxymethylene. We combined our novel results with those of previous studies to provide the first global review of microplastic contamination of table salts. We found that 94% of salt products tested worldwide contained microplastics, with 3 out of 27 polymer types (polyethylene terephthalate, polypropylene, polyethylene) accounting for the majority of all particles. Averaging over seven separate studies, table salts contain a mean of 140.2 microplastic particles/kg. With a mean annual salt consumption of ~3.75 kg/year, humans therefore annually ingest several hundred microplastic particles from salt alone.

Environmental pollution with plastic is a growing problem worldwide. This study investigates the microplastic and mesoplastic pollution of Xialiao Beach in northern Taiwan. Sand from the surface (1 cm depth) was collected in a systematic manner. A total of 80 samples were taken along four transects, and plastic particles (≥1 mm) were extracted and quantified. In total, 1939 microplastic particles were recovered, with an average of 96.8 particles per 1 m2. Statistical analysis showed that the backshore had significantly more microplastic particles than the supra littoral or intertidal. Extrapolating the numbers of plastic particles found, approximately 6.8 million plastic particles (≥1 mm) weighing about 250.4 kg should be found in the surface layer of Xialiao Beach. Resampling curves were created from the data set, which showed that at minimum 20 samples should be taken to adequately estimate the mean particle abundance.

Sedimentary deposits of past extreme events such as tsunamis, typhoons, or floods on coastal plains are important records for understanding such events and for hazard preparation of future similar events. On the coastal Ilan Plain in northeastern Taiwan, there has been no report for any of these types of event deposits. Toward this end, this study aims to identify event deposits on the Ilan Plain with geomorphic and sedimentological analyses. North of the Lanyang River, we identified one event layer that was likely produced by a flood/river channel avulsion event. South of the river, we also found an event that was probably a flood that covered the area without significant erosion, consistent with the well-preserved beach ridges and inter-ridge lowlands of the area. Our experiences in the Ilan Plain area suggest that it is important to search for sites with high potentials of event layer deposition and preservation, as well as with multiple ways to distinguish the sources of the deposits in future similar studies.

Man-made coastal debris pollution is a growing concern for Taiwan. In 2004, Taiwanese environmental organizations led by the “Society of Wilderness” began gathering data on 19 categories of debris items collected during cleanup events. We present our analysis of the resulting 12-year dataset collated from 541 events held between October 2004 and December 2016. In total, 904,302 items weighing 131,358.3 kg were collected, and 63.6% and 27.2% of items were made of either plastic or plastic mixed with other materials, respectively. The five most commonly recorded debris categories were plastic shopping bags, plastic bottle caps, disposable tablewares, fishing equipment, and plastic drinking straws. We estimated that during the 12-year period on average between 3.7 and 7.9 million items weighing 560–1110 metric tons polluted Taiwan's coastline. We offer recommendations for improving the quality of data collected during Taiwan's cleanup events and report some policy changes due partly to previous reports of this dataset.

Continuous sedimentation and detailed stratigraphy are key parameters for a complete paleo-earthquake record. Here, we present a new paleoseismological study across the main strike-slip fault branch of the Dead Sea fault in Lebanon. We aim to expand the current knowledge on local paleoseismicity and seismic behavior of strike-slip plate boundary faults and to explore the limitations of paleoseismology and dating methods. The trench, dug in the Jbab el-Homr basin, reveals a succession of remarkable, very thin (0.1 to 5 cm) palustrine and lacustrine layers, ruptured by at least 17 earthquakes. Absolute ages of 4 samples are obtained from three luminescence-dating techniques targeting fine-grain minerals. Blue-green stimulated luminescence (BGSL) on quartz and post-infrared infrared-stimulated luminescence at 225 °C on polymineral aliquots led to consistent ages, while ages from infrared-stimulated luminescence at 50 °C on polymineral aliquots appeared underestimated. The quartz BGSL ages are 26.9 ± 2.3 ka at 0.50 m depth and 30.8 ± 2.9 ka at 3.65 m depth. During this time period of 3.9 ka ([0; 9.1 ka]), 14 surface-rupturing events occurred with a mean return time of 280 years ([0; 650 years]) and probable clustering. This return time is much shorter than the 1127 ± 135 years return time previously determined at the Yammouneh site, located 30 km south. Although fault segmentation and temporal variations in the earthquake cycle remain possible causes for such different records, we argue that the high-resolution stratigraphy in Jbab is the main factor, enabling us to record small deformations related to smaller-magnitude events that may have been missed in the rougher strata of Yammouneh. Indeed, focusing only on larger events of Jbab, we obtain a mean return time of 720 years ([0; 1670 years]) that is compatible with the Yammouneh record.

The open mine Schöningen is well known for its well-exposed Tertiary and Quaternary sediment sequences and outstanding archaeological find horizons. During mining activities in 2008 and 2009 a lacustrine, glacial and glaciofluvial sequence, as well as loess deposits of the YoungerMiddle to Late Pleistocene were exposed at the archaeological site Schöningen 12 II (so-called "DB-Pfeiler"), a former dam of the German Railways embankment. Chronometric ages for deposits in Schöningen are sparse. The age and correlation of the archaeological horizons of the ReinsdorfInterglacial and related deposits are under debate. Samples for pollen analysis were taken from interglacial lacustrine sediments, whereas samples for luminescence dating were collected from unconformably overlying glacial, glaciofluvial, and loess deposits, to obtain depositional ages, toreconstruct the interglacial environmental conditions, and for biostratigraphical correlation. The palynological results of the interglacial lacustrine deposits at site Schöningen 12 II allow a detailed correlation with the Reinsdorf Interglacial pollen zonation of site Schöningen13 II of the southern mining area. Luminescence dating results of the overlying glacial and glaciofluvial deposits provided only minimum ages, which contradictory to previous chronometric data indicate a deposition prior to MIS 9, whereas the upper part of the sequence (fine-grained basinfill) has most likely been deposited prior to MIS 6. Deposition of the loess on top of the sequence took place during MIS 2 (Weichselian, LGM).

Plastic pollution is now ubiquitous in the world's oceans, and studies have shown macroplastic and microplastic pollution of beaches in several East Asian countries. However, to our knowledge, no study of microplastic pollution has been conducted in Taiwan yet. Therefore, we collected sand samples from four beaches along the northern coast of Taiwan in 2015 and extracted microplastic particles using a saturated NaCl solution. Microplastic particles were identified using synchrotron-based FTIR spectroscopy. We recovered 4 to 532 particles from eight 0.0125m(3) samples, with a total of 1097 particles weighing 0.771g. A negative trend between the size of the particles and their numbers was documented. We thus established that microplastic pollution was ubiquitous along Taiwan's northern coast. Future research should more comprehensively sample beaches around the entirety of Taiwan's coast, and special emphasis should be placed on identifying different sources and movements of microplastic.

In the last few decades optically stimulated luminescence (OSL) dating has become an important tool in geochronological studies. The great advantage of the method, i.e. dating the depositional age of sediments directly, can be impaired by incomplete bleaching of grains. This can result in a scattered distribution of equivalent doses (DE), leading to incorrect estimation of the depositional age. Thoroughly tested protocols as well as good data analysis with adequate statistical methods are important to overcome this problem. In this study, samples from young fluvial sand and flood plain deposits from the Elbe River in northern Germany were investigated to compare its depositional ages from different age models with well-known historical dates. Coarse grain quartz (100–200 μm and 150–250 μm) and polymineral fine grains (4–11 μm) were dated using the single aliquot regenerative (SAR) dose protocol. The paleodose (DP) was calculated from the DE data set using different approaches. Results were compared with the development of the Elbe River, which is well-documented by historical records and maps covering the last 1,000 years. Depending on the statistical approach it can be demonstrated that depositional ages significantly differ from the most likely depositional age. For the investigated coarse grain quartz samples all ages calculated from the MAM-3UL, including their uncertainties, are within the historical documented age. Results of the polymineral fine grain samples are overestimating the historically documented depositional age, indicating undetectable incomplete bleaching. This study shows the importance of using an adequate statistical approach to calculate reliable OSL ages from fluvial sediments.

Während in den Lössgebieten Mitteleuropas die Lössstratigraphie und die menschliche Besiedlung der Lössgebiete sowohl eiszeitlich wie auch im Holozän gut bekannt sind, liegen zu den Sandlössgebieten der Altmoränengebiete keine neueren Erkenntnisse zur zeitlichen Stellung der Sedimente oder zur Siedlungsgeschichte und zum Einfluss auf die Bodenentwicklung vor. In der Arbeit werden aus einem Sandlössgebiet in der Lüneburger Heide zwei Bodenprofile vorgestellt deren Gliederung einen Einblick in die Genese der vergangenen 10 000 Jahre erlaubt. Die Profile wurden sedimentologisch, pedologisch und palynologisch untersucht und charakterisiert. Die Datierung der Profile erfolgte mittels optisch stimulierter Lumineszenz (OSL) und Radiokarbondatierung. Die Ergebnisse legen einen menschlichen Einfluss auf die Böden ab dem späten Neolithikum nahe. Darunter sind Erosions- und Akkumulationsprozesse und insbesondere eine Anreicherung mit organischem Material zu fassen. Erstmals können mit dieser Studie Datierungen von Sedimenten und Böden des Altmoränengebietes präsentiert werden.

Earthquakes that trigger tsunamis are of great geological, ecological and socio-economic importance. The knowledge of the recurrence interval of these events will give information about the hazard for a region. Coastal sediments on the Andaman Islands located in the eastern Bay of Bengal were investigated to find evidence for palaeotsunamis and palaeoearthquakes. Fieldwork was conducted on Red Skin Island and North Cinque Island, south of South Andaman. Sediment material from event-layers was dated by optically stimulated luminescence and radiocarbon dating method. The results show evidence possibly for one earthquake at about 1,000 or 3,000 years before the present together with deposits from possible tsunamis and storms. The complex pattern of co- and post-seismic uplift and subsidence of the Andaman Islands is reflected in the investigated sections and made it possible to reconstruct an event-history for the last 3,000 years.
