MOBR is the study of synergistic effects meteorological, oceanographic, biological, and radiological parameters on each other to monitor state atmosphere, hydrosphere, lithosphere, biosphere in a particular marine environment.In our work, 24 data were collected assess ecosystems around Madras nuclear power plant.The results demonstrated significant influence sea level pressure surface air temperature, its role wind formation, control affecting current velocity, subsequent cover percentage living non-living organisms, biodiversity, as well seasonal behavior Uranium 238 (U-238) across various spheres.The observations highlighted key aspect area, which was predominantly covered by high sand ratios (76 88% during premonsoon monsoon seasons, respectively).This dominance impacted biodiversity significantly.Interestingly, highest values U-238 recorded sediment, dust, crabs, green algae season, with exception fish.This pattern result prevailing dominance.This considered first attempt infer interactions between (MOBR) ecosystems.

This study investigated the Spatio-temporal variations in physicochemical properties of surface seawater along northern Red sea.41 samples were gathered from Ras Gharieb, Hurghada, Safaga, and Qusier cities to measure conservative (temperature, DO, salinity, pH) parameters.In parallel, non-conservative parameters (ammonia, phosphorous, nitrite, nitrate) analyzed via a colorimetric-spectrophotometer instrument.Our findings revealed that physical fluctuated between 19.01 ± 0.75 -35.01 0.47 ºC, 5.05 0.54 -11.70 1.06 mg/l, 39.81 0.35 -42.31 0.50 ‰, 8.10 0.14 -8.50 0.44 for temperature, pH, respectively.While chemical ranged 0.12 0.06 1.53 0.20 mg/l ammonia, BDL 1.71 0.23 1.38 0.05 0.09 4.50 1.22 nitrate.Statistically, no discernible variation was detected among different seasons all measurements except phosphorous (P < 0.05).In addition, Pearson's correlation analysis showed some positive or negative relationships temperature salinity (r = 0.75), pH 0.50), phosphate 0.70), 0.73), nitrite nitrate 0.71), DO -0.73),DO -0.50),pH ammonia -0.71),as well as -0.55).These results indicate physico-chemical should be taken into account during development management strategies protect Egyptian marine environment, especially sea areas.

Utilizing fluctuation asymmetry to assess the effects of U-238 radioactivity on the marine ecosystem around the Madras nuclear power plant, India

Oceanological and Hydrobiological Studies, Journal Year: 2023, Volume and Issue: 52(4), P. 437 - 445

The monitoring of marine ecosystems is crucial due to the growing threat posed by nuclear power plants and other anthropogenic emissions. In our work, we used a straightforward low-cost biomonitoring technique called fluctuation asymmetry (FA) examine variation between left right sides (developmental instability) organisms’ traits that were influenced genetic environmental variables in early stages ontogenesis. specimens fish (Leiognathus sp.) crabs (Portunus sanguinolentus) collected seasonally as bioindicators determine effects Uranium-238 (U-238) radioactivity around plant. obtained results revealed FA values not considered typical (FA = 0) all seasons. Moreover, Leiognathus sp. exhibited insignificant for particular characteristic through different seasons, while significant occurred amongst characteristics themselves throughout same season. Inversely, four Portunus sanguinolentus displayed seasonal them all. Statistically, there was strong positive correlation (r 0.5, p < 0.05) U-238 flesh both organisms but it sign any radioactive pollution exists.
