In Australia, where many rivers have warmer temperature regimes, native fish species have been eliminated, and macroinvertebrate fauna have been drastically altered. Due to the sudden fall of water temperature the contraction on dam and bridge pylon may take place. In the United States, thermal pollution from industrial sources is generated mostly by power plants, petroleum refineries, pulp and paper mills, chemical plants, steel mills and smelters.
Heated water from these sources may be controlled with: Some facilities use once-through cooling OTC systems which do not reduce temperature as effectively as the above systems.
During warm weather, urban runoff can have significant thermal impacts on small streams, as stormwater passes over hot parking lots, roads and sidewalks. Stormwater management facilities that absorb runoff or direct it into groundwater, such as bioretention systems and infiltration basins, can reduce these thermal effects. Retention basins tend to be less effective at reducing temperature, as the water may be heated by the sun before being discharged to a receiving stream.
Noise pollution is excessive, displeasing human, animal, or machine-created environmental noise that disrupts the activity or balance of human or animal life. The word noise may be from the Latin word nauseas, which means disgust or discomfort. The source of most outdoor noise worldwide is mainly construction and transportation systems, including motor vehicle noise, aircraft noise, and rail noise.
Poor urban planning may give rise to noise pollution, since side-by-side industrial and residential buildings can result in noise pollution in the residential area. High noise levels can contribute to cardiovascular effects in humans, a rise in blood pressure, and an increase in stress and vasoconstriction, and an increased incidence of coronary artery disease.
In animals, noise can increase the risk of death by altering predator or prey detection and avoidance, interfere with reproduction and navigation, and contribute to permanent hearing loss.
There are many different types of noise pollution. There are man-made noises, such as those created by city traffic, construction sites, airports and subway terminals. In fact, most forms of transportation have an associated noise factor. The other type of noise that can be disruptive and irritating are environmental, such as a loud thunderstorm or the noise created by barking dogs and other animals.
Your mind just turns the noise down to a livable degree. Many types of manmade products and equipment cause noise pollution. For example, household appliances, televisions, electronic cooling fans, vacuum cleaners, and HVAC equipment all contribute to daily noise pollution. Even your pets may create a certain level of noise. Noise pollution effects both health and behavior. Unwanted sound noise can damage physiological and psychological health.
Noise pollution can cause annoyance and aggression, hypertension, high stress levels, tinnitus, hearing loss, sleep disturbances, and other harmful effects. Furthermore, stress and hypertension are the leading causes to health problems.
Chronic exposure to noise may cause noise-induced hearing loss. Older males exposed to significant occupational noise demonstratesignificantly reduced hearing sensitivity than their non-exposed peers, though differences in hearing sensitivity decrease with time and the two groups are indistinguishable by age A comparison of Maaban tribesmen, who were insignificantly exposed to transportation or industrial noise, to a typical U.
High noise levels can contribute to cardiovascular effects and exposure to moderately high levels during a single eight hour period causes a statistical rise in blood pressure of five to ten points and an increase in stress and vasoconstriction leading to the increased blood pressure noted above as well as to increased incidence of coronary artery disease. Noise pollution is also a cause of annoyance. A study by Spanish researchers found that in urban areas households are willing to pay approximately four Euros per decibel per year for noise reduction.
The effects of noise pollution on human health is a complex topic since not only does it have a physical effect, but also a behavioral and even mental effect. Noise can make a person nervous, antsy, irritable and, in some cases, angry. Some noises are cited as being responsible for aggressive behavior in some individuals. Noise can have a detrimental effect on animals, increasing the risk of death by changing the delicate balance in predator or prey detection and avoidance, and interfering the use of the sounds in communication especially in relation to reproduction and in navigation.
Acoustic overexposure can lead to temporary or permanent loss of hearing. An impact of noise on animal life is the reduction of usable habitat that noisy areas may cause, which in the case of endangered species may be part of the path to extinction.
Noise pollution has caused the death of certain species of whales that beachedthemselves after being exposed to the loud sound of military sonar see also Marine mammals and sonar. Noise also makes species communicate louder, which is called Lombard vocal response.
These unheard voices might be warnings, finding of prey, or preparations of net-bubbling. European Robins living in urban environments are more likely to sing at night in places with high levels of noise pollution during the day, suggesting that they sing at night because it is quieter, and their message can propagate through the environment more clearly.
The same study showed that daytime noise was a stronger predictor of nocturnal singing than night-time light pollution, to which the phenomenon is often attributed. Zebra finches become less faithful to their partners when exposed to traffic noise.
An important factor in applying these strategies is a computer model for roadway noise, that is capable of addressing local topography, meteorology, traffic operations and hypothetical mitigation. Costs of building-in mitigation can be modest, provided these solutions are sought in the planning stage of a roadway project. Altering flight paths and time of day runway has benefitted residents near airports. Accessed September 15, We will write a custom essay sample on Thermal Pollution specifically for you.
