Nitrous oxide, commonly known as laughing gas, gained popularity in the medical field as an anesthetic. It also causes euphoria and acts as an anxiolytic in the human body. However, there is limited information available on its toxicity, particularly its neurotoxicity, which has been emerging in younger populations using it for recreational purposes. Here, we present a case of a young patient with subacute combined degeneration secondary to vitamin B12 deficiency from chronic use of nitrous oxide.

Mature compost can reduce gaseous emissions in composting, but its regulation mechanisms via biotic and abiotic functions are largely unknown. This study used fresh and inactivated mature compost as additives in kitchen waste composting to unveil the relevant mechanisms using metagenomic analysis. Results showed that mature compost reduce gaseous emission by improving physiochemical properties and inoculating functional microbes.

The mangrove ecosystems store a significant amount of "blue carbon" to mitigate global climate change, but also serve as hotspots for greenhouse gases (GHGs: CO, CH and NO) production. The CH and NO emissions offset mangrove carbon benefits, however, the extent of this effect remains inadequately quantified. By applying the 36 h time-series observations and mapping cruises, here we investigated the spatial and temporal distribution of GHGs and their fluxes in Dongzhaigang (DZG) bay, the largest mangrove ecosystem in China, at tidal and monthly scales.

Sulfur-siderite driven autotrophic denitrification (SSAD) has received increasing attention for nutrient removal in constructed wetlands (CWs). Nevertheless, its effectiveness in simultaneous water purification and greenhouse gases (GHGs) reduction remains obscure. In this study, three vertical flow constructed wetlands (VFCWs), filled with quartz sand (CCW), sulfur (S-CW), and sulfur-siderite mixed substrates (SS-CW), were constructed to investigate the underlying mechanisms of SSAD on water purification enhancement and GHGs reduction.

The increasing use of recreational nitrous oxide ([Formula: see text]O) in the Netherlands and its link to traffic accidents highlights the need for reliable detection methods for law enforcement. This study focused on ex vivo detection of [Formula: see text]O in exhaled breath and examining its persistence in the human body. Firstly, a low-cost portable infrared based detector was selected and validated to detect [Formula: see text]O in air.

Denitrification has been identified as a significant nitrate attenuation process in groundwater systems. Hence, accurate quantification of denitrification rates is consequently important for the better understanding and assessment of nitrate contamination of groundwater systems. There are, however, few studies that have investigated quantification of shallow groundwater denitrification rates using different analytical approaches or assuming different kinetic reaction models.
