Abstract Cities evolve through phases of construction, demolition, vacancy, and redevelopment, each impacting water movement at the land surface by altering soil hydrologic properties, cover, topography. Currently unknown is whether variable physical vegetative characteristics associated with vacant parcels introduced demolition may absorb rainfall thereby diminish stormwater runoff. To investigate this, we evaluate how lots modulate citywide partitioning synthesizing a novel field dataset across 500+ in Buffalo, New York, USA. Vacant lot infiltration rates vary widely (0.001 to 5.39 cm h −1 ), though are generally well-vegetated gently sloped. Extending estimates 2400 parcels, estimate that lands cumulatively infiltrate 51–54% additional annual volume as compared pre-demolition state, part reducing disconnecting impervious areas. Our findings differentiate purposeful landscapes can alleviate large fluxes into aging wastewater infrastructure.

Stormwater exposure can cause acute mortality of coho salmon (Oncorhynchus kisutch), and 6PPD-quinone (6PPD-Q) was identified as the primary causal toxicant. Commercial standards 6PPD-Q recently became available; their analysis highlighted a systematic high bias in prior reporting concerning 6PPD-Q. A commercial standard used to re-confirm toxicity estimates juvenile develop liquid chromatography-tandem mass spectrometry analytical method for quantification. Peak area responses were ∼15 times higher than those in-house standards, updated LC50 value (95 ng/L) ∼8.3-fold lower that previously reported. These data support relative comparisons occurrence while confirming substantial lethality While environmental concentrations are expected be lower, also more toxic calculated should categorized “very highly toxic” pollutant aquatic organisms. Isotope dilution-tandem methods enabled accurate quantification (limits <10 within samples.

Abstract Water pollution is a growing threat to humanity due the pervasiveness of contaminants in water bodies. Significant efforts have been made separate these hazardous components purify polluted through various methods. However, conventional remediation methods suffer from limitations such as low uptake capacity or selectivity, and current quality standards cannot be met. Recently, advanced porous materials (APMs) shown promise improved segregation compared traditional selectivity. These feature merits high surface area versatile functionality, rendering them ideal platforms for design novel adsorbents. This Review summarizes development employment APMs variety treatments accompanied by assessments task‐specific adsorption performance. Finally, we discuss our perspectives on future opportunities purification.

6PPD, a tire rubber antioxidant, poses substantial ecological risks because it can form highly toxic quinone transformation product (TP), 6PPD-quinone (6PPDQ), during exposure to gas-phase ozone. Important data gaps exist regarding the structures, reaction mechanisms, and environmental occurrence of TPs from 6PPD ozonation. To address these gaps, ozonation was conducted over 24–168 h were characterized using high-resolution mass spectrometry. The probable structures proposed for 23 with 5 subsequently standard-verified.
