• Carbon footprint detector: an empirical approach for green and clean energy in smart cities  
  by Rohit Rastogi, Aditya Gola, Aditya Raj 
  Abstract: In the wake of high technology, carbon emission has increased that raises environmental degradation as a natural consequence. It threatens environmental sustainability and encourages persons and organisations to measure and minimise their carbon footprint. The article deals with designing and implementing a carbon footprint detector, a tool that attempts to measure and track carbon emissions according to the activities and patterns of consumption by users. It uses a combination of input data in terms of energy usage, kinds of transportation used, and product consumptions calculated for carbon equivalent emissions. The tool can also offer recommendations on how to reduce the overall carbon footprint in a household. Real-time feedback and historical data tracking help inform further, more sustainable choices. This detector acts as a very vital tool for raising awareness over some of the major behavioural changes that lead toward sustainability goals. Further, it gives simple solutions to solve excess carbon footprint at household levels.

• The confined spaces and their additional risks: the reality of condominiums in Recife and greater Recife  
  by Cláudia Cândida De Lima Eustáquio, Felipe Mendes Da Cruz, Rogério Pontes De Araújo, Augusto Cesar Cabral Santos 
  Abstract: Hazardous atmospheres pose significant risks to activities conducted in confined spaces, resulting in fatalities. The objective of this article is to investigate the atmospheric risks in confined spaces in condominiums, as well as to analyse the additional risks present in these locations, considered to be relevant. To this end, inspections were conducted in a commercial condominium and fifteen residential condominiums, applying a research checklist to characterise the confined spaces. A field experiment, using rapidresponse sensors, was also conducted to measure the presence of gases and the deficiency or enrichment of oxygen in the business condominium. Measurements of concentrations and oxygen levels analysed the gases O2, CO, CO2, H2S, and LEL and did not reveal the presence of harmful agents to the health, safety, and life of workers, according to the standard parameters. As for the residential condominiums, it was found that the risk of falls from height was very significant.
  Keywords: confined spaces; additional risks; hazardous atmospheres; atmospheric risks; rapid-response sensors.

• Flame retardant pollution and economic coordinated development based on risk assessment and PCA-MLR method  
  by Li Li, Liang Li 
  Abstract: This study proposes a pollution and health risk assessment method based on risk assessment and principal component analysis multiple linear regression for flame retardant pollution in economically developed areas. This method uses hazard index and carcinogenic risk to assess its health impact and extracts the main influencing components using principal component analysis. Experiments have shown that the content of flame retardants in soil has gradually increased along the river flow direction, with values of 189 ng/g, 122 ng/g, and 48 ng/g in urban, suburban, and rural areas, respectively. Decabromodiphenyl ether had the highest contribution rate to the flame retardant content in soil, with an average of 82.5%, which was 73.3% and 76.3% higher than pentabromodiphenyl ether and octabromodiphenyl ether. Therefore, this study can effectively evaluate the pollution situation of flame retardants in soil and promote the coordinated development of pollution control and social economy.

• Ecological Evaluation of Electromechanical Equipment Installation in Environmental Protection Engineering  
  by Lingjian Wang, Jian Li, Guohu Luo, Jinmei Guo, Qiuxiang Yu 
  Abstract: This study aims to improve the installation technology of environmental engineering electromechanical equipment, enhance installation quality and ecological environment management level. This study used data review, survey interviews, and other methods to preliminarily identify safety risk factors in the construction of mechanical and electrical installation engineering, and evaluated them using the LEC evaluation method. Based on this, this article constructs a safety risk assessment index system and evaluation standards for mechanical and electrical installation engineering construction, and verifies the feasibility and reliability of the risk assessment system through specific engineering project examples. The research results indicate that the newly developed integrated configuration system for electromechanical equipment can help improve the efficiency and professionalism of designer configuration scheme design, and promote sustainable development in the field of architecture.
  Keywords: Environmental protection engineering; mechanical and electrical equipment installation; ecological risk; risk assessment index system.
