Real-Time Monitoring of Environmental Parameters in Abu Dhabi’s Coastal Waters Using Buoy Data: Insights and Implications for Sustainable Management

2025-05-05T09:26:33+02:00

The present study was carried out to study the hydrological parameters of Abu Dhabi coastal waters during January 2022 to December 2023 by using integrated real time buoy data which is an effective tool for early warning systems for conservation needs. The variations in temperature, salinity and pH were prominent in relation to stations and seasons. Pronounced changes were also observed in other parameters such as chlorophyll-a, DO and density of blue-green algae. Temperature and conductivity were found maximum at open sea coastal stations, Salinity and DO values were recorded maximum open sea coastal stations during winter month. Maximum value of pH, blue-green algal density and chlorophyll-a concentration was recorded during winter months. The spatial and seasonal variation of algal density was observed during August, June and February, which showed a strong positive correlation with the station S5 and S3, September, October, November and December had strong positive correlation with the station (S2, S8, S7, S1 and S9) and January and March had strong positive correlation with the station (S4 and S10). The findings of cluster, MDS and PCA analysis showed that variations in hydrological parameters significantly alter the Blue Green algal density. The findings of this study offer enhanced insight into how physico-chemical factors interact and vary over space and time, which is crucial for evaluating the effects of abiotic parameters. To help identify the seasonal variations, trends, and long-term changes in water quality, a long-term real time monitoring through buoy-satellite data needs to be carried out over a number of years.

Spatial Analysis of Chlorophyll-a and Its Correlation with Temperature, Phosphate, and Nitrate in Marine Waters of Abu Dhabi, UAE

Chlorophyll-a is a primary indicator of phytoplankton biomass and is an essential parameter for evaluating Marine Water Quality (MWQ). This study explored the relation between sea surface temperature (SST), Chlorophyll-a (Chl-a), Phosphate (PO₄), and Nitrate (NO₃) concentrations to support in the monitoring and evaluation of the marine environment. Monthly sampling was conducted at 22 ecologically important sites in the Abu Dhabi marine environment, encompassing eight categories, including confined areas, near desalination plants, natural habitats, port and marinas, near nuclear power plant, near public beaches, newly developed area and reference (offshore water). Results revealed Chl-a concentrations ranging from 0.2 to 62.8 µg/L (mean 2.05 µg/L), SST from 18.99 to 34.93 °C (mean 28.64 °C), PO₄ from 5.46 to 2967 µg/L (mean 182.67 µg/L), and NO₃ from 14.17 to 15 599.3 µg/L (mean 369.13 µg/L). Site 2 showed the highest mean Chl-a (24.26 µg/L), PO₄ (1329.36 µg/L), and NO₃ (4316.17 µg/L), while Site 13 had the highest mean SST (29.37 °C). Confined areas recorded the highest mean concentrations of Chl-a (7.47 µg/L), PO₄ (462.28 µg/L), and NO₃ (1332.02 µg/L), while reference areas showed the highest SST (29.06 °C). Statistical analysis correlation indicated that Chl-a positively correlates with PO₄ (0.603) and NO₃ (0.433) but negatively correlates with SST (-0.076). SST showed negative correlations with PO₄ (-0.188) and NO₃ (-0.167), while PO₄ and NO₃ had a strong positive correlation (0.714). These results provide valuable information into the physical and chemical parameters and their correlations in Abu Dhabi waters

The Effects of Plastic and Microplastic Waste on the Marine Environment and the Ocean

2025-03-17T23:12:16+01:00

Globally, plastic pollution is acknowledged as a serious human-caused problem for marine and coastal ecosystems. The main sources of these pollutants in the many ways they enter the ocean are land-based and sea-based. Megaplastic, mesoplastic, macroplastic, and microplastic are among the various sizes and kinds of plastic pollutants that are found in ecosystems. The water, sediment, and biota of marine and coastal environments are widely distributed with primary and secondary microplastics. The vast majority of consumer goods in use today are made of plastic. Every year, almost 280 million tons of plastic are manufactured worldwide, most of which wind up in landfills or the ocean. Plastics can be made from primary chemicals, usually coal, oil, or natural gas, or they can be made by converting natural resources. At least 267 species are impacted by plastic and microplastic globally, including 44% of all seabird species, 43% of all marine mammal species, and 86% of all sea turtle species. Through detrimental effects on human health, shipping, and fishing, this new pollutant has an impact on socioeconomic factors. At the international, regional, and national levels, current and enacted laws, policies, rules, and programs are essential to lowering the amount of plastic waste in the world’s oceans. Last but not least, the plastics industry should implement plastic recycling or upgrading programs to assume global responsibility for the end-of-life of their goods. The main objective of this paper is to show the impact of plastic and microplastic waste on the marine environment and oceans, and some ways to solve this problem.

An Overview of the Environmental Problems of the Used Waters Extracted from the Factories of the Olive Oil Production, and Their Treatment Methods

2025-02-26T18:33:43+01:00

The olive oil industry plays a crucial role in the agricultural economy, particularly in Mediterranean countries. Aligning the industry with the United Nations Sustainable Development Goals (SDGs) is essential for fostering sustainable agriculture, economic growth, and environmental protection. This paper explores how the olive oil sector in Albania contributes to the SDG 6: Clean Water and Sanitation which addresses the industry’s impact on water consumption and pollution. We conduct a survey in Elbasan country, related to the olive oil industry and its impact on the environment. The environmental audit of the Olive oil mill in Selita village result in water and soil pollution because of the septic tank wastewater treatment method applied to the olive oil effluent. In Albania we face this problems in many other olive oils factories. Based on the study results we proposed the mitigation measures to protect environment. We analyzed and proposed the best scenario to treat wastewater for olive oil mills in Elbasan County.

Efficiency Aspects of Durres Wastewater Treatment Plant

2025-02-09T16:29:52+01:00

The sewage system in the city of Durres has been a problem for both residents and ecosystems for years. Urban wastewater had direct effects into surface water, mainly in the Adriatic Sea, and this problem raised the need to build a wastewater treatment plant. The main purpose of this study is to give some aspects of the effectiveness of this wastewater treatment process which is one of the byproducts produced by human activity with a negative impact on all components of the environment. The study presents the description of the study area, the sewage system and the impact of this project on the environment. It is described the functioning of the urban wastewater treatment plant, the working methods followed, and the laboratory analyzes performed to maintain control of this process according to state-set standards. The discussion of the biological and chemical results obtained in the laboratory, are based on data obtained from: determination of wastewater and clean water entering the plant, the equivalent population to which this plant serves, the amount of phosphorus that has to be reduced, effectiveness of the process for total dissolved solids, as well as effectiveness of parameters on output and wetland.
