“…Highway construction is a long-term and large-scale project, which has many effects on the air in the construction process, mainly in the following aspects: first, a large amount of dust will be generated in the process of subgrade excavation and backfilling; second, a large number of raw materials will be used in the construction process, such as lime, fly ash, steel bar, sandstone, cement, asphalt, etc In the process of loading, unloading, transportation and mixing, a lot of dust will be generated, which will cause environmental pollution [3]. At the same time, some chemical reactions will be generated after mixing, which will release harmful gases, thus affecting the air quality and causing environmental pollution.…”

As an important link between urban and rural areas, low-grade highway bears the dual functions of internal distribution traffic and transit traffic. At the same time, low-grade highway also has problems such as complex traffic composition, weak infrastructure and so on. Its environmental protection management ratio is relatively weak in the whole process of construction, which brings many environmental problems and affects ecological benefits. In order to reduce the impact of low-grade highway construction on the surrounding township environment during the construction period and maintain the integrity of the surrounding ecological environment, it is necessary to pay more attention to the environmental problems during the construction period. This paper studies and analyzes the framework system of environmental protection management in the construction period of low-grade highway. Combined with the requirements of environmental protection management in the construction period of highway, it expounds the impact of the construction period of highway on the environment, the existing problems and current situation of environmental protection management, introduces the contents of environmental protection management, and analyzes the framework system of environmental protection management. Based on this, this paper analyzes the impact of low-grade highway construction on the ecological environment, and puts forward the corresponding countermeasures. 1

“…The monitoring of air quality in any given environment is very important, especially environment where certain occupational activities like construction activities which promote poor air quality due to the release of microscopic particles into the ambient air. Research has shown that the major cause of occupational related diseases emanate from air pollution in the work environment.What constitutes the major causes of air pollution during construction activity include fumes from vehicles, emission of dust, as well as acoustic pollution from vehicular movements [1]. Investigation of the impact of construction activity on the ambient air quality revealed that during construction activity, the concentration of airborne particles of 10micrometres increased by 15μgm -3 compared to when there was no construction activity [2].…”

This study considered occupational air pollution index (API) and the effects of meteorological variables for two seasons at selected construction sites in the cities of Owerri and Port-Harcourt. Suspended microscopic particles of the size range 2.5µm and 10 µm generated at the construction sites were collected on filter papers and their concentrations were determined on a monthly basis for 2 seasons (wet and dry seasons). The results showed that air pollution of the selected construction sites were relatively poor. The highest API values recorded during the study for PM2.5 and PM10 at Owerri construction site were 314 and 155, while that of Port-Harcourt were 216 and 106 respectively. Comparing the values of API between Owerri and PortHarcourt construction sites for the period under study, air pollution index at Owerri construction site was higher than that of Port-Harcourt. This difference in API could be attributed to the volume of work and meteorological conditions of the selected construction sites. Occupational exposure to poor air quality has been identified as the cause of increased ischemic heart disease, respiratory problems, and even death among construction workers and workers in other industries, hence the need to ensure air quality monitoring and improvement in our environment and industries.

“…1 Corresponding author: serdariaziev@gmail.com Particles of road dust are in a turbulent flow and have aerodynamic diameter from a few nanometers to tens of µm ( Fig. 1) [2,3]. The settling process of small weighted particles by gravity in a turbulent flow is composed from two processes: a) continuous subsidence of some parts down, inside carrying them pulsating moles, and b) random in direction, frequency and amplitude of particles movement with descents and rises along with carrying them pulsating moles [4].…”
