Land application of biosolids is one potential source pharmaceuticals and personal care products (PPCPs) into agricultural soils. Degradation an important natural attenuation pathway that affects the fate transport PPCPs in soil system could alter process. The present study assessed effect individual mixture compound environments on biodegradation rate half-life three non-steroidal anti-inflamm...

Per- and polyfluoroalkyl substances (PFAS) have gained increasing attention due to the potential health risks that they present. Secondary sludge biosolids are known as notable PFAS emission routes environment. In this study, partitioning behavior of 14 were investigated across four secondary wastewater treatment types (activated sludge, trickling filter, biological nutrient removal, rotating c...

The development of nanotechnology has accelerated the use silver nanoparticles (AgNPs) in household chemicals and accumulation Ag sewage treatment systems. application sludge products to soils raises concerns over safety function biogeochemical cycles soil belowground ecosystem. Here, we assess potential risk transfer under AgNPs exposure its effects on trophic nitrogen (N) through a animal foo...

Biosolids contain a wide variety of organic contaminants that are known for their ability to inhibit PCR. During sample processing, these contaminants are coconcentrated with microorganisms. Elevated concentrations of these compounds in concentrates render samples unsuitable for molecular applications. Glycine-based elution and recovery methods have been shown to generate samples with fewer PCR...

Controlled-release Nitrogen Fertilizers (CRNFs) are an effective fertilization technique by minimizing nutrient loss and making (N) available to plants as they grow. Biochar-based CRNF (BCRNF) technologies have been demonstrated very promising in increase of corn yield. Despite the beneficial effects BCRNFs, their impacts on prokaryotic fungal soil communities not well evaluated. Different form...

The use of biological phosphorus removal by activated sludge has been shown to have adverse effects downstream in the solids handling processes of anaerobic digestion. From struvite formation problems within the digesters to increased polymer dosage and dewatered biosolids solids content. The fundamental cause is unknown however phosphorus removal prior to anaerobic digestion has been shown to ...
