This study identifies the most relevant bands within a hyperspectral data cube for turbidity prediction in inland water. Nine machine learning regressors Cat Boost, Decision Trees, Extra Trees, Gradient Boost, Light Gradient Boost (LightGBM), Recursive Feature Elimination (RFE), Random Forest, Support Vector Regressor (SVR), and Xtreme Gradient Boost (XGBoost) have been used to compute the feature importance of the hyperspectral bands for predicting turbidity. Random Forest has outperformed the other models with a mean absolute percentage error (MAPE) of 1.61%, and the R² of the linear fit is 0.96. Band 77, with a central wavelength of 1067.61 nm, is the most dominating band regarding feature importance. We have also developed a novel framework for turbidity prediction: Stacked Ensemble with Machine Learning Regressors on Optimal Features (SMOF). It employs a stacking ensemble of the nine regressors mentioned above with Random Forest as both base and meta-model, leveraging feature selection outputs. With this framework, the MAPE (%) reached 1.21, while the R² stood at 0.95. The present study also presents a simple statistical algorithm to detect noisy bands in the Hyperspectral Precursor of the Application Mission (PRISMA) data cube. The approach assesses quadrat-wise intra-band spatial coherence using Renyi's entropy thresholding for noisy band segregation. Radiometric calibration error and absorption due to water vapour are the two primary sources of noise within the data cube. Moreover, this research implements the open-source Water Colour Simulator (WASI) to simulate inland water spectra with varied proportions of turbidity. Overall, the study presents an approach to identify noisy bands and integrates the potential wavelengths for turbidity prediction of inland waters.</p>","PeriodicalId":545,"journal":{"name":"Environmental Science and Pollution Research","volume":" ","pages":""},"PeriodicalIF":5.8,"publicationDate":"2024-11-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142708506","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Consequently, this study was undertaken to investigate the impact of seed priming with cold plasma (CP), iron (Fe), and manganese (Mn) nanoparticles (NPs) on salinity modulation in hemp plants, aiming to improve seed germination, plant growth, and biochemical attributes. A pot experiment was conducted with salinity at three levels (0, 60, and 120 mM NaCl) and seed priming at five levels (control, 60 s CP, 90 s CP, 50 mg L^-1 Fe NPs, and 50 mg L^-1 Mn NPs). The results showed that salinity at 120 mM decreased germination percentage (GP, 34%), germination speed (GS, 61%), seedling vigor index (SVI, 47%), shoot weight (38%), root weight (15%), chlorophyll (Chl) a + b (31%), and relative water content (RWC, 24%) while increasing malondialdehyde (MDA, 48%) and proline (39%). Seed priming with CP, Fe NPs, and Mn NPs increased plant weight, GP, GS, SVI, RWC, and Chl but decreased MDA accumulation. Fe NPs and salinity at 60 mM led to high levels of total phenolic content and total flavonoid content, which represent 29 and 44% increases, respectively, compared to the control.

These are harmful to living beings even at lower concentrations as they persist in the body for years and lead to the development of severe diseases. Therefore, the present work was designed to develop a rapid and field-applicable cell-based assay for quick detection of lead and cadmium in biofluids using an RNA biomarker. The RNA biomarker was identified by analyzing the impact of these heavy metals on the gene expression of candidate genes using HepG2 cells. The results showed that the gene expression of AhR pathway-related genes, apoptosis-related genes, MAPK1, and HMOX1 were significantly increased after lead and cadmium treatments (P < 0.05). Interestingly, the gene expression of HMOX1 was increased linearly up to fivefold in a dose and time-dependent manner in the case of both heavy metals which also correlated with an increased secretion of bilirubin from the cells after 6 h treatment. Therefore, the RT-LAMP assay was developed for lead and cadmium toxicity using HMOX1. The positive amplification was visualized in the form of color change of HNB dye from violet to blue in 30 min. Additionally, standard curves were also prepared for the RT-LAMP color change after treatment with different concentrations of lead and cadmium for their quantification in unknown samples. The developed RT-LAMP assay was also validated using lead and cadmium-spiked milk samples. The ROC curve analysis showed 100% sensitivity and specificity for both heavy metals above their MRL value in infant milk substitutes and infant foods.

Understanding the effects of heavy metals on the structure and function of the small intestine, the principal organ responsible for protein digestion and absorption, is therefore crucial. This study investigated tree sparrow nestlings at three developmental stages (3, 6, and 12 days old) in Liujiaxia (LJX), a comparatively unpolluted area, and Baiyin (BY), a heavy metal polluted area, to elucidate the factors and mechanisms by which heavy metals affect nutrient absorption. We compared heavy metal accumulation levels, structural integrity, and protein digestion and absorption functions of the duodenum, jejunum, and ileum. The increase of fluctuating asymmetry and decrease in body condition in tree sparrow nestlings were found to be associated with environmental heavy metal accumulation in the small intestine. Structural impairments of villi and crypts were observed in the duodenum and jejunum of tree sparrow nestlings at 3-, 6-, and 12-day-old in the polluted site BY. Conversely, structures related to the ileum were elevated, and the small intestine of nestlings at all stages exhibited abnormally elevated protein digestibility but diminished absorption of amino acids. However, there was no significant difference in small peptide absorption.

The surface morphology of the film has been studied using the contact mode atomic force microscope (AFM) technique and the average surface roughness was determined to be 36.4 nm. Then, this film was exposed to the vapors of methanol, ethanol, 2-propanol, and 1-butanol with various concentrations varying between 50 and 400 ppm. In addition, studies on response time and repeatability of the sensors have also been carried out. Films exhibit maximum sensing response to methanol vapor while the lowest sensitivity of the film towards 1-butanol has been observed. After an exposure time of 10 min, the frequency shift of 415 Hz was recorded for 400 ppm methanol vapor concentration, while a frequency shift of 215 Hz was observed for the same concentration of 1-butanol. The sensor was 1.30 times more sensitive to methanol vapor than ethanol and 2.00 times more sensitive to methanol than to 1-butanol.
