This review focuses on the behaviour of four psychoactive compounds (carbamazepine, tramadol, sertraline and citalopram) in the environment. The review presents how they may directly affect freshwater systems, soils and living organisms and to which extent. The transformation of these very stable compounds in soils were controlled by oxidation, demethylation, decarboxylation and hydroxylation. Sorption to organic matter and clay particles controlled their mobility. Despite their expected sorption in soils, sediments and sludge, all compounds can be taken up by plants and by fish. In plants, all compounds and several of their metabolites were found...

The development and provision of soil spectral library (SSL) could facilitate the application of near infrared (NIR) spectroscopy for economical, accurate, and efficient determination of soil organic matter (SOM). In this work, the performances of partial least squares regression (PLSR) and convolutional neural network (CNN) combined with the datasets of Zhejiang provincial SSL (ZSSL) and the feature subset (FS) were compared for the prediction of SOM at the target field. The FS dataset was chosen from ZSSL based on similarity to the spectral characteristics of the target samples. The results showed that compared with modelling using ZSSL, modelling...

The aim of this study is to present the seasonal variation of organic matter (OM), total organic carbon (TOC), total nitrogen (TN), and total phosphorus (TP) in the bottom sediments of Marchica Lagoon, a post-restorated lagoon located in the Moroccan Mediterranean, and to estimate the potential role of the geochemistry and granulometry of bottom sediments in the retention of old eutrophication. The organic index of bottom sediment was found generally higher in old-eutrophic and enclosed areas. The surface sediments show variable levels of OM, TOC, TP, and TN; high in some cases (12.3%, 6.71%, 0.70%, and 0.30% respectively). These high levels were recorded...

Soil rill erodibility (Kr) and critical shear stress (τc) are important parameters in some physical soil erosion models. In the present study, the temporal variations in Kr and τc by overland flow were investigated using undisturbed topsoil samples collected from three cropped plots (ryegrass, lucerne, and corn) and a fallow plot. In this study, the potential factors leading to these changes were examined from March to September 2022 in western Sichuan Province, China. The results revealed significant seasonal variations in Kr, τc, soil bulk density...

Plantain is the most important crop for the Peruvian Amazonian population, developed in recent alluvial soils rich in nutrients, but fragile and susceptible to degradation. Therefore, the impact of permanent cultivation was evaluated, through modelling, on indicators of recent alluvial soil quality and production in plantations of Musa paradisiaca L. var. Harton, in the Aguaytia River valley, Peru. The treatments were areas with permanent plantain plantations of 2 (T0), 15 (T1), 4 (T2), and 5 (T3) years of management, evaluating soil physicochemical indicators and plantain production indicators. The results show significant differences for all...
The effects of slope and altitude on soil organic carbon and clay content in different land-uses: A case study in the Czech RepublicOriginal Paper

Soil organic carbon (SOC) and clay, as indicators of soil fertility, are mainly used to determine the ability of soil to retain water and store the nutrients that are necessary for plant growth. However, the distribution of SOC and clay is influenced by topography and land-use. In the present study, the relationships between SOC, clay, altitude, and slope in the topsoil of two different districts in the Czech Republic including the Liberec (71 samples) and Domažlice (67 samples) districts were investigated. To analyse the relationships between slope and SOC, linear regression was used. Results showed that SOC content increased when slope, clay, or altitude...
