Abstract: (98 Views)
Mining activities often cause environmental problems, such as noise pollution, which can endanger ecosystems and human health. This research aimed to study the extent of noise pollution resulting from stone quarry activities in a protected area. For this purpose, sampling was carried out in three directions—north, south, and east—up to a distance of 1 km (11 stations in each direction) and in the west up to a distance of 470 m (5 stations) from the Qanbari stone quarry over one year, from October 2022 to September 2023, between 9:00 and 11:00 a.m. Noise levels were measured using a Cirrus sound level meter (model CR:303), with five samples collected from each station, totaling 2,280 samples. A comparison of the mean sound intensity levels in the four directions—north, south, east, and west—against the international standard limit for daily noise set by the WHO for protected areas (45 dB) showed that the mean sound intensity levels in all directions exceeded the standard limit, indicating noise pollution. Correlation analysis results revealed strong negative correlations between distance and noise, as well as between elevation and noise. In other words, as distance and/or elevation above sea level increased, sound levels decreased. Based on the findings of this study, which highlight the positive effect of geological features such as mountains in reducing noise, it is recommended that land barriers in the form of embankments and hills covered with plants capable of high noise absorption be constructed within a one-kilometer radius of the quarry. Additionally, due to the continuous noise pollution caused by mining activities in the heart of the Basiran no-hunting area, it is suggested that mining operations that disturb wildlife quietness be banned by the Department of Environment. This measure could help increase wildlife populations and enhance the potential of the area to be designated as a fourth-level protected area under the supervision of the Department of Environment.
