“…It's important to understand that no ltration method can completely remove all radioactive pollutants, as stated by Buesseler (2020). Tritium, carbon-14, cobalt-60, and strontium-90 are among the isotopes found in the Fukushima nuclear disaster's treated e uent (Maki et al, 2019). Tritium stands out owing to its unusual properties as a helium isotope that doesn't readily absorb into biological things and its very short half-life of slightly over 12 years (Eidemüller, 2021).…”

The dissemination of treated nuclear wastewater from the Fukushima Daiichi nuclear power plant into the Pacific Ocean has raised profound ecological and public health concerns. This study examines the sociological effects of nuclear waste discharges on marine ecosystems and human communities, with a particular emphasis on the Fukushima event. Utilizing a combination of existing literature review and secondary data analysis, this study explores the distribution of radionuclides in marine settings, their accumulation in the marine food chain, societal hurdles and the associated health risks for humans. Besides that, the positive nature of coefficients demonstrates that each area measured—health, environment, social, and marine life—worsens with higher volumes of discharged water, highlighting the importance of international standards and effective environmental governance in controlling and reducing the effects of nuclear pollutants. The findings also indicate that the spread of radionuclides, notably tritium and carbon-14, presents sustained ecological and health risks, exacerbated by their long-term presence in the environment and propensity to bioaccumulation. In conclude, Fukushima incident starkly demonstrates the prolonged and intricate effects of nuclear waste discharges on marine ecosystems and human health. Therefore, regulatory enhancements are necessary to uphold strict safety standards and ensure international accountability, thereby boosting public confidence and conforming to global best practices in nuclear safety and environmental protection.

“…Another study carried out by Maki et al [13] aimed to forecast the total energy consumption of a WWTP and the consumption in different processes, using a Markov switching model. The data were collected by applying several sensors connected to a WWTP energy distribution network in Japan and transmitted over a 3G line.…”

Forecasting Energy Consumption of Wastewater Treatment Plants with a Transfer Learning Approach for Sustainable Cities

et al. 2021

A major challenge of today’s society is to make large urban centres more sustainable. Improving the energy efficiency of the various infrastructures that make up cities is one aspect being considered when improving their sustainability, with Wastewater Treatment Plants (WWTPs) being one of them. Consequently, this study aims to conceive, tune, and evaluate a set of candidate deep learning models with the goal being to forecast the energy consumption of a WWTP, following a recursive multi-step approach. Three distinct types of models were experimented, in particular, Long Short-Term Memory networks (LSTMs), Gated Recurrent Units (GRUs), and uni-dimensional Convolutional Neural Networks (CNNs). Uni- and multi-variate settings were evaluated, as well as different methods for handling outliers. Promising forecasting results were obtained by CNN-based models, being this difference statistically significant when compared to LSTMs and GRUs, with the best model presenting an approximate overall error of 630 kWh when on a multi-variate setting. Finally, to overcome the problem of data scarcity in WWTPs, transfer learning processes were implemented, with promising results being achieved when using a pre-trained uni-variate CNN model, with the overall error reducing to 325 kWh.

“…The contributions are 80-85% from increasing recycling rates and 10-15% from RPF technology implementation. Maki et al, (2019) apply a Markov switching model to predict future energy demand of one wastewater treatment plant so that necessary energy conservation measures can be taken. A case study approach was employed to examine the effectiveness of this model in the Shinchi wastewater treatment plant in Shinchi town, Fukushima Prefecture, Japan.…”

Rapid urbanization brought many environmental issues, leading to an urgent need on urban environmental governance. This special issue aims to focus on such a topic so that cities can accelerate their transition to equitable, sustainable, and livable Cities. Twenty-six papers were selected in this special issue, with different foci on different topics in different cities. These papers can be categorized into the following: reviews, policy orientations, metric and indicators, consumer behaviors and lifestyles, innovative designs and implementations, and tools. These papers discuss various topics related with urban environmental governance and can provide valuable insights to those city managers so that they can improve their environmental governance and move their cities toward post-fossil carbon societies. By summarizing the key contributions of these papers, an integrated framework on effective urban environmental governance is proposed so that cities can increase their resources efficiency, reduce overall waste production, and respond global climate change.
