“…With the continuous demand for urban development and the demolition of buildings, a large number of contaminated sites have been created causing serious environmental problems in China, due to the waste gas, wastewater, and waste residue emitted from the activities of industrial and mining production and also high regional background level. − These sites would pose a potential risk to human health and the ecological environment through the contamination of soil, sediment, surface water, groundwater, and air migration by hazardous chemicals, − such as heavy metals (e.g., Pb, Cd, Cr, Hg), metalloid (e.g., As), volatile organic compounds (VOCs), , semivolatile organic compounds (SVOCs), and pesticides. , It resulted in different exposure routes such as soil inhalation, surface and groundwater drinking, plant uptake, and accumulation in the food chain for different harmful contaminants. , Additionally, some chemicals in the contaminated soil can leach or enter the groundwater with seepage water, resulting in deterioration of groundwater quality over time and eventually leading to pollution. − …”

Contaminated soil and groundwater can pose significant risks to human health and ecological environments, making the remediation of contaminated sites a pressing and sustained challenge. It is significant to identify key performance indicators and advance environmental management standards of contaminated sites. The traditional study currently focuses on the inflexible collection of related files and displays configurable limitations regarding integrated assessment and in-depth analysis of published standards. In addition, there is a relative lack of research focusing on the analysis of different types of standard documents. Herein, we introduce a cross-systematic retrospective and review for the development of standards of the contaminated sites, including the comprehensive framework, multifaceted analysis, and improved suggestion of soil and groundwater standards related to the environment. The classification and structural characteristics of different types of files are systematically analyzed of over 300 national, trade, local, and group standards for the contaminated sites. It exhibits that trade standards are the main types and testing methods are the important format within numerical considerations of soil standards. The guide standard serves as a crucial component in environmental management for investigating, assessing, and remediating of contaminated sites. Future improvement plans and development directions are proposed for advancing robust technical support for effective soil contamination prevention and control. This multidimensional analysis and the accompanying suggestions can provide improved guidance for Chinese environmental management of contaminated sites and sparkle the application of standards in a wide range of countries.

“…Thirdly, simulation models are employed to estimate the emission characteristics, meteorological conditions, and chemical reactions of distinct pollution sources, predicting pollutant concentration distribution and the contributions of different sources [11,12]. Fourthly, compiling emission inventories for pollutants involves collating and analyzing data from sources such as ships and transportation for a comprehensive view [13,14]. Fifthly, source apportionment techniques help differentiate the impacts of different pollution sources, utilizing methods like chemical mass balance and positive matrix factorization [15][16][17][18].…”

Air pollution is a growing concern in metropolitan areas worldwide, and Shanghai, as one of the world’s busiest ports, faces significant challenges in local air pollution control. Assessing the contribution of a specific port to air pollution is essential for effective environmental management and public health improvement, making the analysis of air pollution contributions at a selected port in Shanghai a pertinent research focus. This study aims to delve into the distribution patterns of atmospheric pollutants in port areas and their influencing factors, utilizing a data-driven approach to unveil the relationship between pollution sources and dispersion. Through a comparative analysis of pollution levels in the port’s interior, surrounding regions, and urban area concentrations, we ascertain that carbon monoxide (CO) and nitric oxide (NO) are the primary pollutants in the port, with concentrations significantly exceeding those of the surrounding areas and urban area levels. These two pollutants exhibit an hourly pattern, with lower levels during the day and higher concentrations at night. Employing a random forest model, this study quantitatively analyzes the contribution rates of different factors to pollutant concentrations. The results indicate that NO concentration is primarily influenced by operational intensity and wind speed, while CO concentration is mainly affected by meteorological factors. Further, an orthogonal experiment reveals that maintaining daily operational vehicle numbers within 5000 effectively controls NO pollution, especially at low wind speeds. Additionally, humidity and temperature exhibit similar trends in influencing NO and CO, with heightened pollution occurring within the range of 75% to 90% humidity and 6 °C to 10 °C temperature. Severe pollution accumulates under stagnant wind conditions with wind speeds below 0.2 m/s. The results help to explore the underlying mechanisms of port pollution further and use machine learning for early pollution prediction, aiding timely warnings and emission reduction strategy formulation.
