Sustainable Application of Biosorption and Bioaccumulation of Persistent Pollutants in Wastewater Treatment: Current Practice

Processes, Journal Year: 2021, Volume and Issue: 9(10), P. 1696 - 1696

Published: Sept. 22, 2021

Persistent toxic substances including persistent organic pollutants and heavy metals have been released in high quantities surface waters by industrial activities. Their presence environmental compartments is causing harmful effects both on the environment human health. It was shown that their removal from wastewaters using conventional methods adsorbents not always a sustainable process. In this circumstance, use of microorganisms for uptake can be seen as being an environmentally-friendly cost-effective strategy treatment effluents. However, spite confirmed potential remediation pollutants, are yet applied at scale. Thus, current paper aims to synthesize analyze available data literature support upscaling microbial-based biosorption bioaccumulation processes. The sources microbial mechanisms pollutant significant results revealed so far scientific identified covered review. Moreover, influence different parameters affecting performance discussed systems also very important designing processes highly considered. analysis performed offers perspective making decisions scaling-up efficient operation, life cycle assessment point view wastewater bioremediation. This since sustainability through standardized methodologies such (LCA), hasn’t analyzed literature.

Role of the Synergistic Interactions of Environmental Pollutants in the Development of Cancer

GeoHealth, Journal Year: 2022, Volume and Issue: 6(4)

Published: April 1, 2022

Abstract There is a growing awareness that the large number of environmental pollutants we are exposed to on daily basis causing major health problems. Compared traditional studies focus individual pollutants, there relatively few how mixtures interact. Several have reported relationship between and development cancer, even when pollutant levels below toxicity reference values. The possibility synergistic interactions different could explain low concentrations can cause These intricate molecular occur through wide variety mechanisms, our understanding physiological effects still limited. purpose this paper discuss recent reports address possible types promote cancer development. Our literature suggest key biological pathways frequently implicated in such processes. include increased production reactive oxygen species, activation by cytochrome P450, aryl hydrocarbon receptor signaling, among others. We need understand pathological vulnerability not only relation basic genetics gene expression, but also terms measurable exposure contaminants. mention for significant improvements future using multitude disciplines, as high‐throughput study models, better tools quantifying patients, innovative pharmacological toxicological studies, high‐efficiency computer analysis, which allow us analyze mechanisms mixtures.

The effects of exposure to environmentally relevant PFAS concentrations for aquatic organisms at different consumer trophic levels: Systematic review and meta-analyses

Environmental Pollution, Journal Year: 2022, Volume and Issue: 315, P. 120422 - 120422

Published: Oct. 13, 2022

Per-and polyfluoroalkyl substances (PFAS) is a collective name for approximately 4700 synthetic chemicals ubiquitous in the aquatic environment worldwide. They are used wide array of products and found living organisms around world. Some PFAS have been associated with cancer, developmental toxicity, endocrine disruption, other health effects. Only fraction currently monitored regulated presence effects on many largely unknown. The aim this study to investigate environmentally relevant concentrations at different consumer trophic levels through systematic review meta-analysis. main result shows that up 13.5 μg/L adverse body size variables secondary consumers. However, no significant liver or gonad somatic indices neither fecundity were found. In addition, results show there large research gaps environments concentrations.

Abstract The existence of thousands per- and polyfluoroalkyl substances (PFAS) evidence that some cause adverse health effects has created immense need to better understand PFAS toxicity move beyond one-chemical-at-a-time approaches hazard assessment for this chemical class. zebrafish model enables rapid large libraries PFAS, powerful comparison compounds in a single vivo system, evaluation across life stages generations, led significant advances research recent years. focus review is assess contemporary findings regarding toxicokinetics, apical outcomes, potential modes action using the model. Much peer-reviewed literature focused on small subset structural subclasses, such as perfluoroalkyl sulfonic acids carboxylic acids. However, data more diverse structures are enabling prioritization concern. Structure-activity comparisons utilization modeling ‘omics technologies have greatly contributed our understanding growing number will surely inform predictive capabilities many future.
