Today, noise pollution is an increasing environmental stressor. Noise maps are recognised as the main tool for assessing and managing environmental noise, but their accuracy largely depends on the sampling method used. The sampling methods most commonly used by different researchers (grid, legislative road types and categorisation methods) were analysed and compared using the city of Talca (Chi...
Agriculture is one of several industries that face criticism today because of its impact on the environment. Pollution prevention technologies can go a long way toward addressing these concerns. They could also benefit producers as they represent a move toward efficiency. The most common environmental pollutants from crop production are sediment, nutrients, and pesticides. This article results ...
Introduction: Application of agricultural machineries such as tractor has been yielded a considerable development in different agricultural activities and productions. However, noticeable health problems such as noise pollution impact the users of these off-road vehicles. The purpose of this study was to determine the noise level induced by agricultural tractors and to evaluate the driver’s noi...
Underwater noise pollution is an increasing environmental problem which might affect communication, behaviour, fitness and consequently species' survival. The most common anthropogenic noises in aquatic habitats derive from shipping. In the present study we investigated the implications of noise pollution from a ship on the sound detectability, namely of conspecific vocalizations in the Lusitan...
In recent decades, population growth and progress of technology have shaped large and compact urban settlements. Existence of huge transportation systems and developed urban infrastructures are among the most important properties of modern cities. In spite of prompt transit and facilitated daily activities, development of transportation systems causes many problems, including traffic, air and n...
Whole-metagenome sequencing (WMS) has emerged as a powerful tool to assess potential public health risks in marine environments by measuring changes in microbial community structure and function in uncultured bacteria. In addition to monitoring public health risks such as antibiotic resistance determinants, it is essential to measure predictors of microbial variation in order to identify natura...
background: noise pollution is currently a major health risk factor for workers in industries. the aim of this study was to investigate noise pollution and implement a control intervention plan for blast furnace in a steel industry. methods: the measurement of sound pressure level (spl) along with frequency analysis was done with the sound-level-meter cell-450 . personal noise exposure was perf...
BACKGROUND Noise pollution is currently a major risk factor in industries in both developed and developing countries.The present study assessed noise pollution in the knitting industry in Iran in 2009 and presented a control method to reduce the rate of noise generation. METHODS The overall noise level was estimated using the network environmental noise assessment method in Sina Poud textile ...
Sound travels very efficiently underwater, so the potential area impacted can be thousands of square kilometers or more. Anthropogenic activities such as commercial shipping, recreational activities, drilling, seismic exploration or energy production (hydroelectric power plants), have made underwater noise pollution an increasing and perhaps dominant factor in the aquatic environment. Nowadays,...
Façades cover a significant amount of surfaces in cities and are constant interaction with the acoustic environment. Noise pollution is one most concerning burdens for public health wellbeing; however, façade performance generally not considered outdoor spaces, contrast to indoor spaces. This study presents systematic literature review examining 40 peer-reviewed papers regarding effects façades...
