The direct impacts of climate change involve a multitude phenomena, including rising sea levels, intensified severe weather events such as droughts and flooding, increased temperatures leading to wildfires, unpredictable fluctuations in rainfall. This comprehensive review intends examine firstly the probable consequences on extreme drought, flood wildfire. subsequently examines release transformation contaminants terrestrial, aquatic, atmospheric environments response driven by change. While drought influence dynamics inorganic organic terrestrial aquatic environments, thereby influencing their mobility transport, wildfire results spread atmosphere. There is nascent awareness change's change-induced environmental scientific community decision-making processes. remediation industry, particular, lags behind adopting adaptive measures for managing contaminated affected events. However, recognizing need assessment represents pivotal first step towards fostering more practices management environments. We highlight urgency collaboration between chemists experts, emphasizing importance jointly assessing fate rigorous action augment risk strategies safeguard health our environment.

Influence of Hydrothermal Carbonization (HTC) Temperature on Hydrochar and Process Liquid for Poultry, Swine, and Dairy Manure

Environments, Journal Year: 2024, Volume and Issue: 11(7), P. 150 - 150

Published: July 14, 2024

Hydrothermal carbonization (HTC) is a promising technology for wet manure treatment by converting animal into valuable fuels, materials, and chemicals. Among other HTC process parameters, the temperature influences products most. As various manures have different compositions, it not certain how hydrochar liquid. To evaluate temperature’s effect on HTC, three (poultry, swine, dairy) were hydrothermally carbonized at temperatures (180, 220, 260 °C), solid liquid characterized their morphology, elemental ions. The carbon contents of reached as high 38.98 ± 0.36% 40.05 0.57% poultry swine manure, respectively, when these treated °C. Ammonium showed an around 30% increase in with temperature. In contrast, decreased 80%, dairy did any remarkable ammonium content. liquids from 220 °C most balanced distribution ions, 4970 673 ppm sodium, 4354 437 ammonium, 2766 417 potassium, 978 82 magnesium, 953 143 calcium, 3607 16 chloride, 39 7 phosphate. These results emphasize manure-specific effects both products, indicating need optimized strategies to enhance processes types manures.

Integrated metabolome and microbiome analysis reveals the effect of rumen-protected sulfur-containing amino acids on the meat quality of Tibetan sheep meat

Frontiers in Microbiology, Journal Year: 2024, Volume and Issue: 15

Published: Feb. 8, 2024

Introduction This study investigated the effects of rumen-protected sulfur-containing amino acids (RPSAA) on rumen and jejunal microbiota as well metabolites meat quality longissimus lumborum (LL) in Tibetan sheep. Methods By combining 16S rDNA sequencing with UHPLC-Q-TOF MS Pearson correlation analysis, relationship between gastrointestinal microbiota, muscle was identified. Results The results showed that feeding RPSAA can increase carcass weight, abdominal fat thickness (AP-2 group), back AP-3 group) water holding capacity (WHC), texture, shear force (SF) LL two groups also increased although fatty content brightness (L*) value significantly decreased AP-2 group. Metabolomics analysis further could influence purine metabolism, thereby affecting L* SF. In addition, beneficial for fermentation jejunum. both groups, abundance Prevotella 1 , Lachnospiraceae NK3A20 group UCG-003 ND3007 Eubacterium nodatum Mogibacterium jejunum increased. contrast, Turicibacter pathogens reduced. above microorganisms regulate by regulating (inosine, hypoxanthine, linoleic acid, palmitic etc.) metabolism. Discussion Overall, reducing levels crude proteins diet is likely to improve sheep, addition RPMET (AP-2) yielding best edible quality, possibly due its ability subsequently metabolites.

Phosphorus Fraction in Hydrochar from Co-Hydrothermal Carbonization of Swine Manure and Rice Straw: An Optimization Analysis Based on Response Surface Methodology

Water, Journal Year: 2024, Volume and Issue: 16(15), P. 2208 - 2208

Published: Aug. 4, 2024

Livestock manure and crop residues are significant sources of phosphorus. However, the ineffectiveness current processing technologies often leads to suboptimal recovery this phosphorus, causing considerable resource wastage environmental pollution. Recently, global research has increasingly been focused on organic waste materials using hydrothermal carbonization technology. This study investigated variations in phosphorus forms hydrochar produced from swine rice straw, employing diverse conditions applying Box–Behnken response surface methodology Hedley’s fractionation method. The results indicated that inorganic predominates hydrochar, with comprising 5–30% total Furthermore, found available content, as measured by NaHCO3 extraction, decreased reaction time temperature process increased. concentrations H2O-P NaHCO3-P fractions increasing times temperatures but increased a higher manure-to-straw ratio. Conversely, NaOH-P HCl-P showed an trend rising temperature, prolonging time, andusing high Consequently, offers vital theoretical practical insights into utilization livestock significantly contributing challenges management sustainability agriculture.
