Steroid hormones are micropollutants that contaminate the water worldwide and exhibit a significant threat to human health environment even at low concentrations. among most common endocrine disruptors investigated due their widespread use as active ingredients in hormonal treatments natural secretions. Three main types of steroids critical for development multiorgan homeostasis estrogens, progesterone, androgens. The sources steroid livestock excretion, veterinary medicines, agricultural runoff, pharmaceuticals. When they reach environment, effects on detrimental. Therefore, this review discusses sources, efficiency available wastewater treatment techniques remove these from wastewater, potential environmental risks, international standards regulate them. This concludes different emerging hybrid approaches show best efficiencies hormone removal wastewater. Moreover, studies have focused estrogen, but equal attention research should also be given progesterone androgen. national need more detailed guidelines encourage advanced systems. Overall, many modern technologies treatments, there is still gap make them sustainable, environmentally safe, cost-efficient.

Advanced adsorbents for ibuprofen removal from aquatic environments: a review

Environmental Chemistry Letters, Journal Year: 2023, Volume and Issue: 22(1), P. 373 - 418

Published: Aug. 25, 2023

Abstract The presence of pharmaceuticals in ecosystems is a major health issue, calling for advanced methods to clean wastewater before effluents reach rivers. Here, we review adsorption remove ibuprofen, with focus on ibuprofen occurrence and toxicity, adsorbents, kinetics, isotherms. Adsorbents include carbon- silica-based materials, metal–organic frameworks, clays, polymers, bioadsorbents. Carbon-based adsorbents allow the highest from 10.8 408 mg/g activated carbon 2.5–1033 biochar. Metal–organic frameworks appear promising due their high surface areas tunable properties morphology. 95% published reports reveal that kinetics follow pseudo-second-order model, indicating predominantly governed by chemical adsorption. 70% disclose Langmuir model describes isotherm, suggesting involves monolayer

The Multifaceted Effects of Non-Steroidal and Non-Opioid Anti-Inflammatory and Analgesic Drugs on Platelets: Current Knowledge, Limitations, and Future Perspectives

Pharmaceuticals, Journal Year: 2024, Volume and Issue: 17(5), P. 627 - 627

Published: May 14, 2024

Non-steroidal anti-inflammatory drugs (NSAIDs) are among the most widely utilized pharmaceuticals worldwide. Besides their recognized effects, these exhibit various other pleiotropic effects in several cells, including platelets. Within this article, multifaceted properties of NSAIDs on platelet functions, activation and viability, as well interaction(s) with established antiplatelet medications, by hindering agonists’ pathways receptors, thoroughly reviewed. The efficacy safety adjunctive therapies for conditions involving inflammation also discussed. Emphasis is given to potential commonly administered such ibuprofen, diclofenac, naproxen ketoprofen, alongside non-opioid analgesic antipyretic medications like paracetamol. This article delves into mechanisms action against different activation, aggregation overall highlighting additional health-promoting agents, without neglecting induced drugs’ side-effects platelets’ functionality thrombocytopenia.
