Wetlands (Wilmington)

Department of Physical and Environmental Sciences, University of Toronto Scarborough, Toronto, ON Canada.
There are increasing global efforts and initiatives aiming to tackle climate change and mitigate its impacts via natural climate solutions (NCS). Wetlands have been considered effective NCS given their capacity to sequester and retain atmospheric carbon dioxide (CO) while also providing a myriad of other ecosystem functions that can assist in mitigating the impacts of climate change. However, wetlands have a dual impact on climate, influencing the atmospheric concentrations of both CO and methane (CH).

The modern metallurgical industry produces approximately 90% of the volume of all produced steel; for this, integrated technology based on fossil materials such as coal, fluxes, and especially iron ore is used. This industry generates large amounts of waste and by-products at almost all stages of production. Alternative iron and steel production technologies based on iron ore, methane, or pure hydrogen are also not waste-free.

However, the simultaneous removal of pollutants and reduction of greenhouse gases (GHG) emissions from high-strength wastewater containing high levels of organic matter and ammonium nitrogen (NH-N) has not get been investigated. The influent COD concentration affected the efficiency of nitrogen removal, GHG emissions and the presence of iron from iron ore, but the COD and TP removal efficiencies remained unaffected.

Investigating responses of soil greenhouse gas (GHG) emissions to vegetation restoration is important for global warming mitigation. On the Loess Plateau, a wide range of vegetation restoration strategies have been implemented to control land degradation. However, the thorough quantification of soil GHG emissions triggered by different modes of vegetation restoration is insufficient.

Stimulant laxatives (especially bisacodyl and sodium picosulfate) are frequently found to be adulterated into slimming foods, causing health-threatening effects to consumers. Sensitive, accurate, easy-to-operate and portable multiplex analytical techniques are still desired for the rapid screening of stimulant laxatives in slimming foods. In this work, a highly sensitive dual-modal colorimetric/photothermal lateral flow immunochromatographic assay (LFIA) was established based on facilely prepared concentrated gold nanoparticles (cAuNPs).
