Air quality[ change change source ] Pollution can be gas or liquid or solid. It can also be classified chemically, such as:
Effects of noise pollution Generally, problems caused by noise pollution include stress related illnesses, speech interference, hearing loss, sleep disruption, and lost productivity. Most importantly, there are three major effects we can look at: Hearing The immediate and acute effect of noise pollution to a person, over a period of time, is impairment of hearing.
Prolonged exposure to impulsive noise to a person will damage their eardrum, which may result in a permanent hearing impairment. Marine Animals Marine scientists are concerned about excessive noise used by oil drills, submarines and other vessels on and inside the ocean.
Many marine animals, especially whales, use hearing to find food, communicate, defend and survive in the ocean. Excessive noises are causing a lot of injuries and deaths to whales.
SONAR is the use of sound by submarines and other fishing vessels to deterring the depth of water, the closeness of an object, or detect movement of other objects in the water Many of these beached whales have suffered physical trauma, including bleeding around the brain, ears and other tissues and large bubbles in their organs.
There is no question that sonar injures and kills whales and dolphins. The physiological manifestations are headaches, irritability and nervousness, feeling of fatigue and decreases work efficiency. For example, being pounded by the siren of fire fighters, police or ambulance in your city all night everyday leave people especially elderly people stresses and tired in the morning.
Its is worth noting that these effects may not sound troubling, but the truth is, with time, the consequences can be very worrying.
The use of military sonar poses a deadly threat to whales and other marine mammals.Pollution is now a common place term, that our ears are attuned to. We hear about the various forms of pollution and read about it through the mass media.
Air pollution is one such form that refers to the contamination of the air, irrespective of indoors or outside. A physical, biological or. Air pollution can cause both short term and long term effects on health and many people are concerned about pollution in the air that they breathe.
These people may include: People with heart or lung conditions, or other breathing problems, whose health may be affected by air pollution. Air pollution is a type of environmental pollution that affects the air and is usually caused by smoke or other harmful gases, mainly oxides of carbon, sulphur and nitrogen..
Many of the world's large cities today have polluted air or low air quality.. Even 2, years ago, the Romans were complaining about the polluted air in their cities. At that time, the air was thick with smoke from fires.
An air pollutant is a material in the air that can have adverse effects on humans and the ecosystem.
The substance can be solid particles, liquid droplets, or gases. Two types of air pollution dominate in the U.S.: ozone and particle pollution 1.
These two pollutants threaten the health and the lives of millions of Americans. Thanks to the Clean Air Act, the U.S. has far less of both pollutants now than in the past.
Still, more than million people live in. The physical aspects of air pollution and its effects on society is the theme of this unit. A teacher would be free to approach the topic from several directions.
