“…In comparison, under aerobic conditions, only carbon dioxide is formed. Previous researchers (Kadlec and Knight 1996;Scholz 2006;Mitsch and Gosselink 2007) pointed out that the aerobic respiration in wetland systems is far more effective with respect to organic matter degradation than anaerobic processes such as fermentation and methanogenesis.…”

“…Dissolved organic carbon comprises dissolved biochemical oxygen demand and other carbon components in solution. While dissolved organic carbon typically represents <1% of the total organic carbon in soil, it represents approximately 90% of the total organic carbon in surface waters (Kadlec and Knight 1996;Wynn and Liehr 2001;Reddy and Delaune 2008). Microbial biomass carbon occurs in heterotrophic micro-floral catabolic activities, transforming organic carbon (energy reserve of the ecosystem) back to inorganic carbon, and mineralizing particulate organic carbon and dissolved organic carbon (D'Angelo and Reddy 1999;Picek et al 2007).…”

“…Since 1980, treatment wetland systems have gained popularity, and have been applied successfully for the treatment of numerous waste streams (Kadlec et al 2000;Haberl et al 2003;Zhang et al 2005;Vymazal 2007) and runoff from urban areas (Scholz 2006), farm yards (Carty et al 2008), and log yards (Hedmark and Scholz 2008). The concept of constructed wetlands applied for the purification of wastewaters has received growing interest because most of these systems are easy to use, require only little maintenance and have low construction costs (Machate et al 1997).…”

“…1). The latter four are present in water, detritus, and soil (Kadlec and Knight 1996). Wynn and Liehr (2001) outlined a carbon cycle comprising the following key components: plant biomass, standing dead plants, particulate organic carbon, dissolved organic carbon, and refractory carbon (i.e.…”

“…In a wetland, organic carbon is converted into compounds including carbon dioxide and methane and/or stored in plants, dead plant matter, microorganisms, or peat. A significant part of the biochemical oxygen demand may be particle-bound and, therefore, susceptible to removal by particulate settling (Kadlec et al 2000).…”

Carbon Storage and Fluxes within Freshwater Wetlands: a Critical Review

We critically review recent literature on carbon storage and fluxes within natural and constructed freshwater wetlands, and specifically address concerns of readers working in applied science and engineering. Our purpose is to review and assess the distribution and conversion of carbon in the water environment, particularly within wetland systems. A key aim is to assess if wetlands are carbon sinks or sources. Carbon sequestration and fluxes in natural and constructed wetlands located around the world has been assessed. All facets of carbon (solid and gaseous forms) have been covered. We draw conclusions based on these studies. Findings indicate that wetlands can be both sources and sinks of carbon, depending on their age, operation, and the environmental boundary conditions such as location and climate. Suggestions for further research needs in the area of carbon storage in wetland sediments are outlined to facilitate the understanding of the processes of carbon storage and removal and also the factors that influence them.

The aquaculture industry is rapidly developing, generating a high amount of wastewater. Inland aquaculture effluents contain nutrients and other substances that can cause eutrophication and the emergence of resistive organisms if released into the environment. Hence, aquaculture wastewater should be treated appropriately for reuse in different applications or safely released into the environment, promoting a sustainable industry and a circular economy. The current review provides insight into aquaculture wastewater generation, constituents, and treatment through various technologies. This study’s treatment technologies could be classified as physical, chemical, and biological. SWOT analysis was conducted on each technology to provide an in-depth understanding of the advantages and drawbacks. Suggestions were also stated to shed light on the importance of a sustainable aquaculture industry and the means to transition toward a circular economy. Graphical abstract
