Engineering a microbiosphere to clean up the ocean – inspiration from the plastisphere

Frontiers in Marine Science, Journal Year: 2023, Volume and Issue: 10

Published: Feb. 1, 2023

Plastic is a ubiquitous material that has become an essential part of our lives. More than one hundred million tons plastic accumulated in the world’s oceans as result poor waste management. This gradually fragments into smaller pieces known microplastics and nanoplastics. These small particles can cause significant damage to marine ecosystems, negatively impact human health. According recent review international patents, majority ocean-cleaning inventions are limited larger 20 μm. Furthermore, such technologies ineffective for nanoplastics, which measure less 1000 nm, or even fibrous plastics. Alternative solutions need be considered large-scale situ removal nanoplastics from ocean. In this perspective, we present concept engineering microbial ecosystem, term microbiosphere. The based on key observations have been made natural plastic-based ecosystems plastispheres. relate solid support material, self-sustainability, attachment plastic, degradation risk pathogenicity. Inspiration taken plastisphere whereby novel ecosystem could designed engineered bioremediation tool rid ocean micro- Such system outcompete pathogens potentially reduce infectious diseases.

Possible Future Risks of Pollution Consequent to the Expansion of Oil and Gas Operations in Qatar

Environment and Pollution, Journal Year: 2023, Volume and Issue: 12(1), P. 12 - 12

Published: Feb. 2, 2023

The air, water, and lands of the Arabian Gulf countries are exposed to contamination involving organic inorganic components resulting from industrial energy sector activities. In Qatar, marine life air primary elements ecosystem that pollution has negatively affected since discovery exportation oil gas. For example, mean concentration PM2.5 reached 105 µg/m3 in 2016. This poor quality been attributed several factors: dust storms, vehicle emissions, emissions. Marine around peninsula Qatar threatened by many factors, including discharge desalinated seawater, gas activities, impact climate change. Studies conducted after multiple major events showed levels various types pollutants were at acceptable levels. Some areas Gulf, such as coasts Saudi Arabia Bahrain, still considered chronically polluted need continual monitoring long term. review discusses status on Qatari coastlines reasons behind persistence current water. role microorganisms (bacteria, algae, fungi) a biological approach for environmental manipulation problems is discussed. agricultural possible sites due potential expansion energy, industry, construction sectors future. Currently, wastewater pumped deep into ground, seawater intruding main-land, which causing significant soils used cultivation crops. Possible measures reported, practical solutions future risks
