The discharge of nutrients and organic pollutants is increasing at an alarming rate, driven by the rapid development of human activities. This growing pollution is contributing to significant environmental issues, including eutrophication, making the treatment of wastewater essential before its release into the environment. Prior to being released into water bodies, treated wastewater must undergo rigorous laboratory analysis. For this reason, analysis using standard methods was carried out at the Laboratory Waterworks in Debrecen on multiple samples taken from various wastewater treatment plants in Hungary. The primary objective of this research was to assess the quality of effluents from (14) wastewater treatment plants and investigate their efficiency by measuring various physicochemical and microbiological parameters as indicators. The microbiological indicator monitored was the heterotrophic count (HPC) by estimating its total number. The results revealed that substantial removal efficiencies were demonstrated by parameters including total nitrogen (TN), chemical oxygen demand (COD), and biochemical oxygen demand (BOD5), with reductions averaging 91%, 92%, and 87%, respectively. However, the reduction in nitrogenous compounds (nitrite NO2? and nitrate NO3?) was limited, indicating areas for process improvement. Recommendations for enhancing treatment efficiency are proposed to optimize the overall performance of the wastewater treatment plants.

Role of Microplastics in Global Warming and Climate Change: A Review / Md. Sohel Parvez, Hadayet Ullah, Omar Faruk, Edina Simon, Herta Czédli

Megjegyzések:
Microplastics (MPs) have become an important concern among scientists and policymakers all around the globe. Despite this, the contribution of MPs to global warming and climate change, a significant aspect of the issue, has been overlooked. Continuous greenhouse gas (GHG) emissions resulting in climate change have long been a major issue with apparent consequences. Climate change and plastic crises are threatening our planet, and the co-occurrence of both would be catastrophic. This article addressed the links between microplastic pollution and climate change; how MPs contribute to climate change by interacting with water, air, and soil; and recommendations to address the issues together. Throughout their lives, plastics emit GHG. MPs in water impede the climate change mitigation potential of the ocean in different ways; they hamper photosynthesis and carbon sequestration by phytoplankton and the Blue Carbon Ecosystem. MPs induce GHG emissions from the soil. Airborne MPs have the potential to aid in cloud formation and interfere with atmospheric cooling. Climate change-induced extreme events redistribute MPs in the environment, causing the pollution to increase vertically and horizontally, which then aggravates the situation in a feedback loop. The evidence acquired in the study implies that MPs and climate change are inextricably linked and that MPs play a vital role in fueling climate change. This bridges the gap between MPs and climate change issues that were previously regarded separately. Due to the linkages between these intertwined challenges, integrated and holistic research and policy measures are required to address both crises concurrently.
