Impact of leachate on soil microbial diversity and its treatment

Scientia Agropecuaria, Journal Year: 2024, Volume and Issue: 15(2), P. 301 - 310

Published: May 13, 2024

This study analyzed the impact of leachate from a temporary landfill on soil microbial diversity in Tingo María, Huánuco region, Peru. Three treatments were used: untreated (S), addition stream water (T0), (T1), and treated by coagulation flocculation (T2), with 828.5 ml/week added three weekly doses. Soil samples collected Reserved Forest Universidad Nacional Agraria de la Selva. Twenty-one randomly distributed taken homogenized for analysis. quality parameters measured included sand, clay, silt, texture, pH, organic matter, nitrogen, phosphorus potassium. As microorganisms, viable aerobes, lactobacilli, actinomycetes, fungi, nitrogen-fixing bacteria, Escherichia coli quantified using specific culture counting methods each them. To evaluate diversity, equity indices (Shannon inverse Simpson), dominance (complementary Simpson Berger Parker) percentage composition microorganism per treatment used. An ANOVA was performed to estimate differences Tukey test at significance level α = 0.05. The showed that leachates affect reducing increasing certain species such as E. coli. They also alter physicochemical parameters, decreasing matter nitrogen but other elements could have implications health functionality.

Sustainable groundwater protection measures through life cycle assessment (LCA) in China: implications from published literatures

Human and Ecological Risk Assessment An International Journal, Journal Year: 2024, Volume and Issue: 30(5-6), P. 570 - 593

Published: July 2, 2024

The availability of groundwater is essential for agriculture, households, and industry. Concerns about its sustainability have been raised due to depletion pollution in various parts China. To address this, a life cycle assessment (LCA) the most suitable approach implementing integrated resources. This research aimed investigate LCA China by analyzing economic, environmental, social based on papers conducted between 1999 2022, providing insights into current state suggesting sustainable measures safeguarding resources specific regions industries study indicates that sector-wise should be taken ensure protection Intercropping drip irrigation systems can effective methods protecting agricultural sector. New power plants constructed water-rich southern regions, long-term water-saving implemented China's coal mining All water regional supply system reduce dependence groundwater. Furthermore, more needed all elements development provinces consume high amounts but limited storage capacity. These recommendations helpful policymakers promoting
