Abstract:
... Land application of microplastic-based biosolids leading to microplastic (MP) contamination in the terrestrial and aquatic ecosystems is largely unknown. Through this report we aim to provide an insight on the current status of MP based biosolid application and identify its potential risks to human and ecological health whilst providing solutions to mitigate them. Complex nature of the soil matrix ...
... There is widespread contamination by per- and polyfluoroalkyl substances (PFAS) across the globe, with adverse effects on human and environmental health. For human exposure, drinking water and dietary exposure have been recognized as important PFAS exposure pathway for the general population. Several documented cases of dairy milk contamination by PFAS have raised concerns over this exposure pathw ...
... Antimicrobials may reach the soil environment from a variety of sources and pathways, including land application of human biosolids and animal manure. Once in soil, antimicrobials can affect the abundance and activity of soil microorganisms and exert selection pressures that enhance the emergence and spread of antimicrobial resistance (AMR). To mitigate the spread of AMR it is important to underst ...
... Literature review provides extensive studies focused on the life cycle assessment of wastewater treatment plants. However, few studies have a mitigation perspective, especially concerning water–energy–nutrient nexus or resource recovery systems for warm-weather countries. In this context, this paper aims to evaluate 10 wastewater treatment plants, based on an upflow anaerobic sludge blanket follow ...
... Elevated human exposure to metals and metalloids (metal(loid)s) may lead to acute sickness and pose a severe threat to human health. The human body is exposed to metal(loid)s principally through food, water, supplements, and (occasionally) air. There are inherent background levels of many metal(loid)s in regional soils as a consequence of geological sources. Baseline levels coupled with anthropoge ...
... Phosphorus is a nutrient that is essential to nature and human life and has attracted attention because of its very limited reserves. Dwindling phosphorus reserves and soaring prices have made the recovery of phosphorus from waste biosolids even more urgent. Waste activated sludge, as the final destination of most of the phosphorus in human domestic and industrial water, has been considered as a r ...
... BACKGROUND: Human wastewater biosolids, hereafter referred to as biosolids, are produced in significant quantities around the world and often applied to an extensive land mass including agricultural fields, forests, mine lands, and urban areas. Land-application of biosolids has been reported in peer-reviewed and non-peer-reviewed work to change soil organic carbon stocks in varying amounts. Determ ...
... Prevalence of antibiotic resistance in the environment is of critical concern from a public health perspective, with many human impacted environments showing increased incidence of antibiotic resistant bacteria. Wastewater treatment environments are of particular interest due to their high levels of antibiotic residuals, which can select for antibiotic resistance genes in bacteria. However, wastew ...

... Bisphenol A (BPA) is an industrial chemical that has been identified by some jurisdictions as an environmental concern. In 2010, Canada concluded that this substance posed a risk to the environment and human health, and implemented actions to reduce its concentrations in the environment. To support these activities, a multimedia analysis of BPA in the Canadian environment was conducted to evaluate ...
... Plasticizers, due to the widespread use of plastics, occur ubiquitously in the environment. The reuse of waste resources (e.g., treated wastewater, biosolids, animal waste) and other practices (e.g., plastic mulching) introduce phthalates into agroecosystems. As a detoxification mechanism, plants are known to convert phthalates to polar monophthalates after uptake, which are followed by further tr ...
... Aqueous film-forming foam, used in firefighting, and biowastes, including biosolids, animal and poultry manures, and composts, provide a major source of poly- and perfluoroalkyl substances (PFAS) input to soil. Large amounts of biowastes are added to soil as a source of nutrients and carbon. They also are added as soil amendments to improve soil health and crop productivity. Plant uptake of PFAS t ...
... Wastewater treatment plants are known to contribute to microplastic (MP) pollution in freshwater and terrestrial environments, but studies on MP abundance in sludge are scarce. This study aimed to (i) conduct a literature review to assess the number and extent of MPs in sludge worldwide, (ii) determine extraction and analytical techniques used to isolate and identify these materials, and (iii) ass ...
... Pharmaceuticals are a class of biologically active compounds used in human and veterinary medicine, while some of them may be applied for feed production and plant growth stimulation. To systemise the knowledge on pharmaceuticals in plant and soil environment, a literature review was performed. Active substances of pharmaceuticals and their metabolites are typically released into the environment t ...
... Halogenated compounds such as polychlorinated biphenyl (PCBs) and polybrominated diphenyl ethers (PBDEs) enter wastewater treatment plants (WWTPs) via the sewage system. These organic contaminants partition between the aqueous and the biosolid phase, where the former is discharged as wastewater effluent. Biosolids from a WWTP provide a hydrophobic surface for adsorption and thus the presence and p ...
... Human enteric pathogens are a major global concern, as they are responsible for thousands of preventable deaths every year. New pathogens in wastewater are constantly emerging. For example, SARS-CoV-2 has been recently detected in domestic sewage and primary sludge. Knowledge about the reduction of viruses in wastewater treatment and their partitioning between the treated liquid effluent versus th ...
... The objective of this study was to describe the epidemiological and molecular surveillance of rotaviruses in tap water, recycled water, and sewage sludge in Thailand from 2007 to 2018. Three hundred and seventy tap water, 202 recycled water, and 72 sewage sludge samples were collected and processed to detect the rotavirus VP7 gene using RT-nested PCR. Rotavirus G genotypes were identified by DNA s ...
... Reclamation of highly degraded mine lands to a sustainable environmental quality has become a major policy concern in many countries with a long mining tradition. This paper reports the soil quality status of a historical mine site fifteen years after its reclamation, using indicators of chemical reactivity, soil fertility and health, and discusses the progress and effectiveness of the implemented ...
... Soil dwelling organisms, plants and many primary consumers in food webs face the challenge of exposure to contaminants of emerging concern (CECs) present in terrestrial systems, including thousands of substances derived from pharmaceutical and personal care products (PPCPs). The recent increase in the consumption of modern human or veterinary drugs has resulted in a surge of anthropogenic pharmace ...
... Autothermal thermophilic aerobic digestion (ATAD) is a microbial fermentation process characterized as a tertiary treatment of waste material carried out in jacketed reactors. The process can be carried out on a variety of waste sludge ranging from human, animal, food, or pharmaceutical waste where the addition of air initiates aerobic digestion of the secondary treated sludge material. Digestion ...

Abstract:
... With rates of community‐associated Clostridium difficile infection (CA‐CDI) increasing worldwide, potential reservoirs/sources of C. difficile in the community are being sought. Since C. difficile is found in animal manure and human biosolids, which are composted for agricultural purposes, composted products could be a source. In this study, the presence of C. difficile in composted products, and ...
