The recovery of degraded areas is imperative for the sustainability mining activities. main action implemented to improve chemical, physical and biological conditions soils, tailings sterile deposits incorporation organic material. Biosolids (hygienized sewage sludge) are among materials that can be applied. However, considering health risk they represent, not all suitable receiving this waste....

Complaints from the public due to odor emissions are one of the biggest problems associated with any biosolids land application program. Chemical additives to reduce or mask odors are one option for producers; however, many chemicals are too expensive or are too unstable to use safely. This project provides a preliminary evaluation of nitrate or nitrate + anthraquinone as additives in controlli...

In Ireland, the land application of biosolids is the preferred option of disposing of municipal sewage waste. Biosolids provide nutrients in the form of nitrogen, phosphorus, potassium and increases organic matter. It is also an economic way for a country to dispose of its municipal waste. However, biosolids may potentially contain a wide range of pathogens, and following rainfall events, may b...

Numerous halogenated organic compounds have been identified as pollutants of concern. Those with high persistence and hydrophobicity may concentrate in biota, sediments, and wastewater sludge. Nonetheless, the release to the environment of many remains largely unrecognized. Stabilized sewage sludge (biosolids) is increasingly being land-applied as a soil amendment. However, understanding the ri...

ABSTRACT Objective This study was aimed at evaluating pertinent physicochemical and microbiological (bacteria and parasites) parameters regarding the biosolids produced by the San Fernando wastewater treatment plant (WWTP) in Itagui, Antioquia, Colombia. Methods Twelve samples were collected and evaluated every month from January to December during 2010. The chemical, physical and microbiologic...

The fate of the endocrine disrupting compound 4-nonylphenol (NP) in an agricultural soil amended with biosolids was assessed in a greenhouse study. A biosolids with a total NP concentration of 900 mg kg(-1) was incorporated into the 4 cm surface layer of soil columns at an agronomic rate equivalent to 1.7 kg m(2). Half of the columns were planted with Triticum aestivum L., red hardy winter whea...

The novel coronavirus, SARS-CoV-2, which has caused millions of death globally is recognized to be unstable and recalcitrant in the environment, especially way it been evolving form new highly transmissible variants. Of particular concerns are human-environment interactions handling reusing environmental materials, such as effluents, sludge, or biosolids laden with SARS-CoV-2 without adequate t...

The impact of repeated application alkaline biosolids (sewage sludge) products over more than a decade on soil concentrations nutrients and trace metals, potential for uptake these elements by crops was investigated analyzing soils from farm fields near Oklahoma City. Total, extractable (by the Modified Morgan test), water-soluble elements, including macronutrients were measured in biosolids-am...

Background: Myelin Oligodendrocyte Glycoprotein (MOG)-induced experimental autoimmune encephalomyelitis (EAE) is the most commonly used mouse model for multiple sclerosis (MS). During the of progression of EAE, microglia, the immunocompetent cells of the brain, become activated and accumulate around demyelinated lesions. Microglial activation is mediated by the extracellular protease tissue Pla...
