background: given the increasing importance of suspended particles and reporting weather conditions in the amount of ultraviolet radiation in many countries, in this study, the data of the maximum amounts of pollution by suspended particles with the size of 10, 2.5 and1 microns (pm10, pm2.5, pm1) which were reported in 1-hour time-series and global ultraviolet index (uvi) were used to predict t...

background: noise pollution has a particular importance in quiet environments such as hospitals. the main objective of this study was to evaluate the effects of noise exposure on the auditory system, blood pressure and precision, concentration and other psycho-neural components. methods: this cross-sectional study was carried out in three large hospitals of shiraz, during the period of 2012 to ...

Noise is defined as unwanted sound. Environmental noise consists of all the unwanted sounds in our communities except that which originates in the workplace. Environmental noise pollution, a form of air pollution, is a threat to health and well-being. It is more severe and widespread than ever before, and it will continue to increase in magnitude and severity because of population growth, urban...

Cities and towns of the world are now facing enormous rise of noise pollution problem due to very high population rise, transport congestion and associated commercial and industrial activities. Burdwan, a district headquarter (100 km away from Kolkata) is one such town where noise pollution is very frequent. In order to assess noise level, noise data were collected from various places of the to...

the contamination of riverbed sediments by heavy metals has assumedserious problems due to their toxicity and accumulative behavior. the present studyinvestigated the concentrations of heavy metals from the bottom sediments of shitalakhyariver to understand the level of contamination and their distribution. the averageconcentrations of heavy metals al, k, ca, mg, fe, as, cu, co, cr, and zn are ...

Oceans represent more than 95% of the world’s biosphere and are among the richest sources of biodiversity on Earth. However, human activities such as shipping and construction of marine infrastructure pose a threat to the quality of marine ecosystems. Due to the dependence of most marine animals on sound for their communication, foraging, protection, and ultimately their survival, the effects o...

Noise features different characteristics that make it different from every other “classic” pollutant. Noise is invisible; it does not smell; it disappears when the source is turned off and leaves no traces in the environment. In addition, when people perceive something wrong about their hearing capacity, it is often long time after the beginning of noise exposure. This fact contributes to stren...

The environmental impact of wind power plants over their life cycle is divided into three stages: construction period, operation period and retired period. The impact is mainly reflected in ecological destruction, noise pollution, water pollution and the effect on bird migration. In response to these environmental effects, suggesting reasonable locations, reducing plant footprint, optimizing co...

Abuja the capital city of Nigeria has experienced rapid development and high influx of people with the implication of increased generation of noise. Hence the need to evaluate the noise pollution level of the city. Measurement of equivalent noise level was carried out in 35 locations around the city using a CR811C integrated sound level meter. Result showed that the day time mean equivalent noi...
