This study evaluates the reasons and factors making soil pollution by poly- perfluoroalkyl substances (PFASs) a wicked problem, reflecting upon nature, persistence, mobility, bioaccumulative properties of these compounds. The current regulation trends in production use such are also explored. highlights conflict between need for phasing out PFASs their indispensable role many strategic applications. We summarize knowledge on complex chemical to highly variable soils, mechanisms partitioning transport soil, exposure pathways humans. In particular, we focus that lead PFAS accumulation edible parts cultivated plants present some potential sustainable management practices could result risk mitigation environmental remediation actions. stemming from merging theoretical considerations pragmatic approaches mitigating problems related agricultural soils. highlight importance co-creation processes adoption solutions vast polluted areas make impacted populations discouraged, like being front an ‘untameable beast’, leading protests irrational behavior. our opinion, this might engage population more optimistic strategies tackle soliciting authorities stakeholders implement beyond actual practice supporting new policy development.

Treated sewage sludge, or biosolids, are used worldwide to improve soil quality and fertility due their high organic matter content micro- macronutrients. However, biosolids also introduce contaminants into the environment. This review assessed recent publications on occurrence, environmental fate, transportation mechanisms of 419 emerging concern (CEC) across four matrices: soils, dust. Among these, 229 CECs were positively detected at least once. The focuses various CECs, including 18 therapeutical classes pharmaceutical products, personal care products (parabens chlorophenolic antimicrobials), hormones, plastic-related compounds (bisphenols phthalates), rubber antioxidants (substituted diphenylamines para-phenylenediamines), neonicotinoid insecticides. Phthalates dominate biosolid composition, accounting for over 97% total weight investigated, followed by pharmaceuticals (1.87%), (0.57%), hormones (0.09%), (0.07%), bisphenols (0.05%). 50 most prevalent include phthalates [e.g., di (2-ethylhexyl) phthalate-DEHP, butyl benzyl phthalate-BBzP], antifungals (e.g., miconazole-MCZ, ketoconazole-KTZ), antimicrobials triclocarban-TCC, triclosan-TCS), fluoroquinolone antibiotics ofloxacin-OFL, ciprofloxacin-CPF), cardiovascular medications telmisartan-TMS, propafenone-PPF), analgesics salicylic acid-SA, naproxen-NPX), mestranol-EEME, progesterone-P), antidepressants sertraline-SRT, amitriptyline-AMT), lipid regulators fenofibrate-FNF). Analytical techniques like matrix-assisted laser desorption/ionization mass spectrometry imaging (MALDI-MSI) have emerged as a valuable tool qualitative analysis, allowing identifying in biosolids. fate transport dynamics studied influenced physicochemical properties (water solubility, volatility, degradation time, sorption capacity, bioaccumulation potential) conditions (temperature, pH, moisture content). Furthermore, characteristics, such matter, microbial activity, play key roles adsorption, degradation, persistence environments. Additionally, wastewater treatment processes impact transformation removal affecting partitioning between treated effluents sludge.
