TL;DR: The results improve the understanding of P and its labile components within a spatially explicit context and distinguish P-enriched areas from unaffected ("natural") areas and intermediate zones that are currently undergoing change as P is mobilized and translocated.

TL;DR: The Bt fermentation process using sludge as raw material was successfully scaled up and resulted in high productivity for toxin protein yield and a high protease activity.

TL;DR: In this article, the United States Environmental Protection Agency (USEPA) stated that no specific protections against SARS-CoV-2, the virus that causes COVID-19 infections, are recommended for employees involved in wastewater management operations with residuals, sludge, and biosolids at water resource recovery facilities.

TL;DR: Soil test data showed that there was no heavy metal accumulation in the biosolids-amended soil even after 10 years of biosolid application, and bacteriological levels of the soil and groundwater samples were close to the background level and below the permissible limits, respectively, thereby showing no pathogen contamination.

TL;DR: The United States regulations are designed to protect human health by minimizing the contact of humans with pathogenic microorganisms, such as enteric viruses or Ascaris sp. as discussed by the authors.
