“…The first intended attempts at channel engineering in Czechia were documented during the 17th century ce and they aimed to improve channel navigation (Dreslerová et al, 2004) or flood protection (Elznicová et al, 2021). Subsequently, channel straightening and the complete conversion of floodplains into crop fields and built‐up areas followed during the period of industrialisation in the last century (Dreslerová et al, 2004; Faměra et al, 2021; Kalicki et al, 2020; Wolf et al, 2021). Similarly, many weirs were built along the Jizera River, which have definitely suppressed the fluvial dynamics.…”

“…Regarding the possible human influence on fluvial systems in Central Europe, changes in land use since the Neolithic spread of agriculture and, most importantly, in the Middle Ages (Broothaerts et al, 2021; Brown et al, 2018; Dotterweich, 2008; Notebaert et al, 2018; Słowik et al, 2021; Stolz et al, 2013) led to the erosion of agriculturally fostered soil and hence a change in sediment delivery over several millennia. Furthermore, prior to direct channel engineering during the industrial period that included embankments and flow manipulation (Faměra et al, 2021; Gibling, 2018; Kalicki et al, 2020; Matys Grygar et al, 2011), the construction of watermills, fortifications, bridges, related weirs and mill canals represented an important anthropogenic factor that has directly influenced floodplains since the Middle Ages (Brown et al, 2018; Buchty‐Lemke & Lehmkuhl, 2018; Gibling, 2018; Houben et al, 2013; Lewin, 2010; Maaß & Schüttrumpf, 2019). The typical consequences of these activities were a reduction of former multiple‐channel systems to single‐thread streams (Lewin, 2010), a reduction of the channel number of braiding rivers (Stecca et al, 2019) and a decrease in sinuosity of meandering channels (Vayssière et al, 2020).…”

The Jizera River in Czechia is a typical mid-sized Central European watercourse. Its floodplain shows a morphological contrast between the laterally stable low-sinuous current channel and preserved palaeomeanders. The aim of this paper was to date and explain the obvious metamorphosis of the channel pattern from meandering to low-sinuous. We analysed the morphology of the lower river reach using a digital terrain model (DTM) and historical maps from the 1840s. Furthermore, the floodplain architecture was described based on the DTM, geophysical imaging (ground penetrating radar, GPR), sediment lithology and anthropogenic contamination using geochemical proxies, and optically stimulated luminescence (OSL) dating. The geochemical proxies were processed using log-ratio methods from the compositional data analysis toolbox. According to our results the Jizera River showed signs of systematic lateral floodplain reworking during the Late Holocene with only minor aggradation, although parts of the catchment are covered by easily erodible loess.Interestingly, vertical aggradation did not show a significant increase during the last millennium. In the main study area, this limited vertical aggradation resulted in the preservation of palaeomeander fragments and palaeochannel belts with 100-200 m mean width in the 300-600 m wide floodplain, which are recognisable in the topography and in subsurface GPR imaging. This channel meandering took place between around 4 and 1.2 ka, and the transition towards the laterally stable modern channel with low sinuosity occurred around 1.2 ka. This timing indicates a climatic rather than anthropogenic impact, which was rather weak around that time. One likely cause for this transition was the influx of material from ravines incised into the sandstone valley edges during past climatic extremes. Subsequently, the re-establishment of a meandering pattern was possibly prevented by a combination of low fluvial activity and the construction of weirs that reduced stream power.

Leafy vegetables cultivated in kitchen gardens and suburban areas often accumulate excessive amounts of heavy metals and pose a threat to human health. For this reason, plenty of studies have focused on low accumulation variety screening. However, identifying specific leafy vegetable varieties according to the foliar uptake of air pollution remains to be explored (despite foliar uptake being an important pathway for heavy-metal accumulation). Therefore, in this study, the lead (Pb) and cadmium (Cd) contents, leaf morphology, and particle matter contents were analyzed in a micro-area experiment using 20 common vegetables. The results show that the Pb content in leaves ranged from 0.70 to 3.86 mg kg−1, and the Cd content ranged from 0.21 to 0.99 mg kg−1. Atmospheric particles were clearly scattered on the leaf surface, and the particles were smaller than the stomata. Considering the Pb and Cd contents in the leaves and roots, stomata width-to-length ratio, leaf area size, enrichment factor, and translocation factor, Yidianhongxiancai, Qingxiancai, Baiyuanyexiancai, Nanjingjiangengbai and Sijixiaobaicai were recommended for planting in kitchen gardens and suburban areas as they have low accumulation characteristics. Identifying the influencing factors in the accumulation of heavy metals in vegetables through foliar uptake is important to help plant physiologists/environmentalists/policy makers to select suitable varieties for planting in air-polluted areas and thus reduce their threat to human health.

Searching for a sustainable solution to increasing chemical pollution

The growing world population and the development of civilization put pressure on the environment. Irreversible climate changes, biodiversity loss, ocean acidification, land and water degradation, and food scarcity took place. Climate changes affect human health through extreme atmospheric phenomena or indirect effects of ecosystem disruption. The intensification of natural disasters increases the risk of technical failures, and the growing production and release of larger quantities and more new chemical compounds, with different hazard potentials, exceeds the environment’s adaptability and societies’ ability to monitor changes and conduct safety assessments. The article reviews the knowledge and approach to the possibility of reducing the risks and effects of events resulting from chemical pollution. As stated, prevention of further environmental degradation and increased preparedness for natural disasters caused by climate change is critical to public safety and requires contingency plans to continuously adapt to the changing frequency, intensity, and scale of natural disasters.
