Seawater reverse osmosis (SWRO) desalination facilities produce freshwater and, at the same time, discharge hypersaline brine that often includes various chemical additives such as antiscalants and coagulants. This dense can sink to sea bottom creep over seabed, reaching up 5 km from point. Previous reviews have discussed effects of SWRO on marine ecosystems, yet little attention has been paid impacts benthic habitats. review comprehensibly discusses fauna flora. We previous studies indicated a suite by organisms, including bacteria, seagrasses, polychaetes, corals. The within mixing zones range impaired activities morphological deformations changes in community composition. Recent modeling work demonstrated could spread beyond zone, for several tens kilometers impair nutrient fluxes sediment water column. also provide possible perspective brine's impact biogeochemical process zone subsurface.

Accumulation associated additives, polyphosphonate-based ferric-based coagulants porewater, may change redox hence, processes sediments. With demand drinking escalating worldwide, volumes are predicted triple during current century. Future efforts should focus development operation viable technologies minimize discharged environments, along with environmentally friendly additives. However, application these be partly subsidized governmental stakeholders safeguard coastal ecosystems facilities.

Seagrasses, which are considered among the most ecologically valuable and endangered coastal ecosystems, have a narrowly limited distribution in south-east Pacific, where Zostera chilensis is only remaining relict. Due to water scarcity, desalination industry has grown last decades central-north coasts of Chile, may be relevant address terms potential impacts on benthic communities due their associated high-salinity brine discharges subtidal ecosystems. In this work, we assessed ecophysiological cellular responses desalination-extrapolable hypersalinity conditions Z. chilensis. Mesocosms experiments were performed for 10 days, plants exposed 3 different salinity treatments: 34 psu (control), 37 40 psu. Photosynthetic performance, H2O2 accumulation, ascorbate content (reduced oxidized) measured, as well relative gene expression enzymes related osmotic regulation oxidative stress; these, at 1, 3, 6 days. showed decrease photosynthetic parameters such electron transport rate (ETRmax) saturation irradiance (EkETR) under treatments, while non-photochemical quenching (NPQmax) presented an initial increment subsequent decline levels increased with hypersalinity, dehydroascorbate psu, although decreased along experimental period. Increased salinities also triggered genes ion osmolyte syntheses, but salinity-dependent up-regulated mostly those reactive oxygen species metabolism.

Desalination residual brines are mostly discharged to marine environments, which can produce osmotic stress on sensitive benthic organisms. In this investigation, we performed transplantation experiments nearby desalination plants using two brown macroalgae species from a cosmopolitan genus: Dictyota kunthii (Chile) and dichotoma (Spain). Parameters related photosynthetic activity oxidative were evaluated at 3 7 days for D. , 6 ; each 2 different impacted sites 1 control. We observed that brine exposition both in Chile generated marked response reflected decrease of primary productivity (ETR max ), light requirement (Ek ETR an excessive thermal dissipation (NPQ especially days. similar impaired was recorded but only the highest influence site during day 3. Regarding stress, displayed high levels H O when exposed brine-influenced sites.

Seawater desalination by reverse osmosis is growing exponentially due to water scarcity. Byproducts of this process (e.g. brines), are generally discharged directly into the coastal ecosystem, causing detrimental effects, on benthic organisms. Understanding cellular stress response these organisms (biomarkers), could be crucial for establishing appropriate salinity thresholds brines. Early biomarkers can serve as valuable tools monitoring health status brine-impacted organisms, enabling prediction long-term irreversible damage caused industry. In study, we conducted laboratory-controlled experiments assess and molecular against brine exposure in two salinity-sensitive Mediterranean seagrasses: Posidonia oceanica Cymodocea nodosa. Treatments involved 39, 41, 43 psu, 6 h 7 days. Results indicated that photosynthetic performance remained unaffected across all treatments. However, under P.

Additionally, displayed an antioxidant at higher salinities accumulating phenolic compounds within ascorbate d; whereas predominant mechanisms were accumulation total radical scavenging activity, was evident after d brines exposure. Finally, transcriptomic analyses exposed psu days revealed a poor up-regulation genes associated with brassinosteroid abiotic response, while high down-regulation related primary metabolism detected. nodosa, up-regulated DNA repair, cell cycle regulation, reproduction, down-regulated mainly photosynthesis ribosome assembly. Overall, findings suggest critical salinity-damage threshold both seagrasses; despite moderate overexpression several transcripts confer salt tolerance, essential biological processes severely downregulated.
