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 in the leaves, indicating the mobility and transformation of the compounds within the plant systems. Factors that control the compounds mobility in plants were found to be the pH of soils and the xylem flow. As for fish, many of the compounds were found in the brain and muscles of fish, some of which, depending on the species, affected the behaviour of the fish. The implications of these compounds so widely present in the environment indicate the need for certain measures to be put into place to prevent these compounds from continuously entering plant and animal systems.

China Title: Strategies and methods for predicting soil organic matter at the field scale based on the provincial near infrared spectral database Abstract: 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 using FS can greatly improve the prediction accuracy of the PLSR model, but the impact on the performance of the CNN model was limited. The method of mean squared Euclidean distance (MSD) was an effective way for determining the optimal spiking sample size for the PLSR model only using the spectral data of the spiking subset and the prediction set. The PLSR model combined with the FS dataset and the spiking subset determined by MSD achieved the optimal prediction results among all developed models, which is an accurate and easy-to-implement solution for the SOM determination based on ZSSL.

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 in the central part of the lagoon and in areas subjected to high anthropogenic pressure, including wastewater discharges. Our results indicated that sediments are an excellent immobilizer of organic matter (C, N, and P), although, there was no correlation between sediment grain size and organic matter content. The absence of correlation might be explained by currentology and hydrodynamics, but also by the bathymetry of the lagoon. Therefore, sediments must be implicated in any lagoon restoration strategy and the site development plan.

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 (SD), soil cohesion (SC), and soil water-stable aggregate (WSA). The Kr values were significantly lower, whereas τc values were slightly higher for cropped plots when compared to that for the fallow plot. The mean Kr values for cropped plots were 4.51~17.26 times lower than that for the fallow plot. In contrast, the mean τc values for the cropped plots were 1.03~1.08 times higher than that for the fallow plots. The results also indicated a negative correlation of Kr with SD, SC, WSA, soil organic matter content (SOC), and root weight density (RWD), while a positive correlation of τc with SD, SC, WSA, and RWD. Furthermore, an exponential decrease in Kr was observed with an increase in SD, SC, WSA, SOC, and RWD. An increase in SD, SC, WSA, and RWD of the experimental plots led to a further increase in τc.

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 yield and soil indicators evaluated, except for bulk density (Bd), clay fraction, soil organic matter (OM) and N. The modelling determined a significant positive impact on Bd and a significant negative impact on pH, P, pseudostem diameter and height, commercial fingers and bunch weight. In conclusion, the modelling shows trends of quality and yield reduction in 15 years of permanent management of plantain Var. Harton, and compromises the sustainability of the agroecosystem in the medium term.

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 increased; however, there were no significant correlations between SOC and clay in both districts. Clay increased with decreasing slope, but clay and altitude were not correlated well in both areas. Then, study areas were divided into three land-use types including arable land, forest, and complex system of agriculture, parcels, and forests. Consequently, the correlations between SOC and slope and clay and slope were generally improved, indicating the importance of land-use on SOC and clay content. Additionally, using multiple regression with several topographic factors can provide a better prediction of SOC and clay content in each land-use for both districts, indicating the complex effects of topography on SOC and clay.
