“…Fang Fang [10] et al, compared the manual monitoring with the online monitoring equipment, and concluded that the manual monitoring method was reliable, the monitoring data was authentic and credible, and had a good correlation with the online data, which provided a technical basis for the government to enforce the law on the online monitoring data of dust, and played a guiding role. Urban dust monitoring is of great significance for the prevention and control of air pollution and the reduction of respiratory diseases [11] [12].With the deepening of the concept of green site, the requirements of the construction site are becoming more and more strict, and the civilized construction such as dust monitoring and control, noise control, and site environment has been paid more and more attention. In many studies, although the current urban dust monitoring has been greatly developed, there are still some problems such as insufficient monitoring in some places and delayed transmission of monitoring data.…”

Construction site dust is one of the main sources of urban air pollution. In order to improve urban air quality and reduce the probability of respiratory diseases among construction workers, effective measures must be taken to control construction site dust. Dust monitoring is an important measure to reduce construction pollution to the surrounding environment. Vigorously developing dust monitoring is the only way to build a civilized construction and green city. Improving dust monitoring at urban construction sites has important practical significance for urban air quality control and accurate treatment of dust at construction sites. Dust monitoring can improve the appearance of the city, increase the investment of investors, and promote the economic development of the city. At the same time, it can also increase the living comfort and happiness index of residents, so dust monitoring is very necessary. In this paper, the research status, necessity and development benefits of urban construction site dust monitoring are expounded, then sort out the key points of dust monitoring technology, and give some suggestions to the possible problems in the existing technology to ensure the smooth implementation of dust monitoring. And put forward the proposal with the dust treatment and control from construction unit, construction unit and supervision unit three aspects to help reduce the construction of dust pollution.

“…The contribution of coal-red sources to PAHs is less than that of automobile sources and natural gas sources, due to the local government's achievements in coal substitution. However, the contribution of coal sources to PAHs in winter has signi cantly increased because coal is still the primary fuel source in this area, which is used in power plants and central heating system (Zhang et al 2021). In addition, the contribution of coal sources in spring was also relatively high, which is related to the six-month heating season in Shihezi.…”

In this study, we investigated the occurrence of particulate matter (PM2.5)-bound polycyclic aromatic hydrocarbons (PAHs) in the atmosphere in Shihezi, China and estimated their incremental lifetime cancer risk (ILCR). In addition, the potential sources of PM2.5-bound PAHs were statistically estimated using principal component analysis and positive matrix factorization. The backward trajectory was employed to determine the potential source area using the HYSPLIT software. Concentrations of PM2.5 and 16 PM2.5-bound PAHs ranged from 4.32 μg/m3 to 114.67 μg/m3 and 6.26 ng/m3 to 114.79 ng/m3, respectively, with the highest PAH concentrations occurring in the winter. Three principal components were analyzed by PCA, namely a combination of coal combustion sources and vehicle emissions, fugitive dust, and industrial emissions. Five sources were analyzed by positive matrix factorization (PMF) including coal combustion, vehicle emissions, fugitive dust, industrial emissions, and natural gas emissions. Risk assessment analysis showed that source-specific lung cancer risk assessment was in the 10-6–10-5 range, which constitutes a cancer risk that exceeds the guideline safety value (10-6) according to the U.S. Environmental Protection Agency. It is necessary to take measures to reduce the concentration of PM2.5-bound PAHs in order to reduce human health hazards.

“…-10 for high-traffic region and 2.89 × 10 −11 to 3.71 × 10 −10 for industrial region, which lower than in this study. Moreover, some previous studies reported that the ILCR model analysis of PAHs inhalation was negligible human health risk [7], [17], [25], [37], which could be explained by cancer risk levels for ingestion and dermal contact route including the different dermal exposure area, exposure duration, and ingest a variety of contaminated dusts as a result of hand-to-mouth actions [38]. Childhood, on the other hand, is an especially sensitive stage of development, with cancer risks up to an order of magnitude higher per year of exposure than in adults [39].…”

BACKGROUND: A city's industrial area's air quality has become a major priority. PM2.5-bound polycyclic aromatic hydrocarbons (PAHs) are one of the most common pollutants in urban-industrial area, and can be linked to health problems. AIM: This study aims to 1) investigate PM2.5 and PAHs emitted from roadside area (RS) and industrial estate (IE) in Rayong city 2) assess the inhalation of PM2.5 and PAHs on the human health of the age group. METHODS: PM2.5-bound PAHs were investigated and thier carcinogenic risk was evalued in this study. PM2.5 samples were collected on quartz filters contained in a mini-volume air sampler and analyzed for PAHs by GC-MS. RESULTS: The average PM2.5 concentrations at RS and IE were 43.3±26.8 and 40.4±21.7 µg/m3, while the values of total PAHs in both sites were 1.68±1.53 and 1.34±1.22 ng/m3, respectively. However, it was found that the PM2.5 and PAHs values were not significantly different (p>0.05). The results revealed that the individual lifetime cancer risk (Ric) of PM2.5 values for children and adults at both sites indicated acceptable cancer risk (10-6 to10-4). According to the incremental lifetime cancer risk (ILCR) values of PAHs for different age groups, exposure to PAHs in PM2.5 through the inhalation pathway was a negligible (<10-6). CONCLUSION: As a result, the PM2.5 concentrations have substantial implications for Rayong city’s environmental management and protection, relating to car emissions and coal combustion.
