Contaminants spreading around in air can travel large distances in a short time. The main construction contaminants that spread around by wind include: PM10 (particulate matter with diameter less than 10 microns generating polluted dust pahs bound to particulate matter, vocs (volatile organic compounds asbestos, gases such as carbon monoxide, carbon dioxide, and nitrogen oxides. Water Pollution the surface water runoff and groundwater at and close to a construction site become polluted with various materials used in the construction work. As described for air pollution above, the following construction contaminants can pollute the water: vocs, paints, clues, diesel, oils, other toxic chemicals, and cement. The immediate effect is creating turbidity in the runoff water and affected surface and groundwater (since some of the runoff water may infiltrate in subsurface reaching groundwater. In fact both groundwater below your home and surface runoff close to your home may constitute a source of pollution emanating from construction sites. Domestic animals and pets may drink contaminated water and soil may become contaminated too.

Construction reviews sites are found both within urban and rural areas, often in the close proximity of homes. Due to their proximity to homes and the materials used, construction sites may generate home pollution. This involves air, water, soil, and/or noise pollution. Additionally, construction work may reveal existing subsurface pollution. In such situation, construction work is stopped and costly remediation is needed. Thus, construction work may generate construction pollution problems affecting both home owners and construction site owners. Moreover, construction workers (especially in the past) may be exposed to pollution.

5-Electronic scrap The main problems that the technological industry presents to the environment are two: The shelf life of line manufactured products is relatively short. This has accelerated growth and must be constantly innovated to not be out of the market, since products are generally obsolete and discarded, regardless of whether they work or not. Thus, like plastic, electronic scrap accumulates day by day massively on planet earth, in addition to electronic devices have harmful materials for health and the environment, such as lead and mercury. 6-Deforestation Deforestation is 100 man-made. The indiscriminate cutting of trees for economic purposes seems to have no limits. Some consequences of deforestation: Floods : trees absorb large amounts of water, thus avoiding overflows of rivers and watersheds. Destruction of biodiversity : many species of plants and animals are in danger of extinction due to the alteration of their natural habitat.
Climate change : Trees absorb the greenhouse gases that cause global warming, in addition to blocking the rays of the sun at daytime. While wood is a necessary resource in everyday life, in order to avoid problems in the future, replanting should be a legal obligation every time a tree is cut. 7-Laws and education The laws governing massive polluters (factories) have not been enough to curb the devastation of the environment and the natural destruction of particular areas of planet earth. On the education side, just the last two decades began to take action on the issue accordingly. A person in many cases contaminates without having a minimum awareness of the grain of sand that is contributing to the global damage of the planet. Laws and education have a profound impact on this cause.
Noise, unlike the two previous cases and most forms of pollution, is not something that prevails in time and presents a problem by accumulation. However, it has other ways of affecting the environment. Excessive sound disturbs normal living conditions in a particular area, and this has consequences, especially in terms of health, both for animals and for humans. Animals that have the most acute auditory sense, depend almost 100 of this to locate their prey and communicate. An alteration of the sonic waves is a total confusion for them, and interrupts their normal habits of life.
In both cases (animals and humans excessive noise not only affects the hearing ability, but also causes other health damages (physical and psychological damage). Again, urban areas and cosmopolitan cities are the areas most affected by noise pollution; transport, together with any machine that uses an exploding engine (for example, lawn mowers) play an important role in this type of pollution. Unlike the items listed above, the water contamination can occur both naturally and by acts of man, although the latter has greater responsibility for. Water pollution from natural sources may be due to: Climatic factors. Ashes of a volcano. However, these natural causes do not pose a greater danger and imbalance on a global scale. And as far as man is concerned, the causes are practically innumerable, the ocean has become a dump of all kinds since industrialization, added to the water that flows into rivers and seas from urban areas and chemical and radioactive waste from factories. Water pollution affects not only the aquatic ecosystem, but all living beings on the planet.

Then, a serious problem arises in the long term. Burying plastic is not the best option, as it is not a biodegradable material. Of course, the idea that the ocean can swallow it is also ruled out. Then, the best option to avoid the accumulation over the centuries of this synthetic material would be the burning. Burning the plastic would help free the earth and oceans from having to take over tons of this material, essays but in turn, would be contributing again to the first item in the listing, which is the emission of toxic gases. Keeping in mind that virtually every element of everyday use is made of plastic due to the low cost of manufacturing, it is a very difficult problem to solve. 3-Annoying noises, sound pollution (or noise pollution ) is not a minor issue.
1-Automotive industry, in every city, especially the cosmopolitan ones, vehicles of daily use produce different types of gases harmful to health and the environment, such as: Carbon dioxide. These gases and particles contribute to air pollution. Vehicle transportation is essential in the daily life of people, and necessary because of current economic and industrial movements. Even so, measures can be taken to reduce the impact of pollution, such as using bicycles to travel short distances or essay using public transport. The idea of the use of electric cars for the future, free of pollutant emissions for the environment, has now come into force. 2-Proliferation of plastic, the creation of plastic has its origins in 1907 in New York. Since then, it has been part of a countless number of products on the market. The main problem with plastic is that it takes many years to decompose (on average, five hundred years). Added to that, its low cost of production, so its proliferation is inevitable.
to stop polluting activities. The causes of environmental pollution are very varied, and most are due to the activity of man. We live in a consumer society, where the useful life of a physical product is very limited, and soon, it becomes trash that contributes as a further element to pollution. Many of the products are non-biodegradable materials and this is a long-term problem, since this type of material does not decompose easily and is usually used daily (plastic, metal, glass, batteries, etc.). Completely eliminating the use of practices and materials responsible for the causes of environmental pollution is practically impossible, as they were created with the aim of making life easier for people. The solution to these problems must be others, such as the recycling. Often one tends to believe that large factories are the highest responsible for the causes of environmental pollution, but this is half-right, since current overpopulation is a very influential factor.
In addition environmental pollution spoils the natural beauty of our planet. Pollution is as complicated as serious problem. Automobiles are polluting the air but they provide transportation for the people. Factories pollute the air and the water but they provide jobs for people and produce necessary goods. Fertilizers and pesticides are important for growing crops but they can ruin soil. Thus, people would have to stop using many useful things if they wanted to end pollution immediately. Most night people do not want that of course. But pollution can be reduced gradually.

But until now pollution plan was not such a serious problem. People lived in uncrowned rural areas and did not have pollution — causing machines. With the development of crowded industrial cities which put huge amounts of pollutants into small areas, the problem has become more important. Automobiles and other new inventions make pollution steadily worse. Since the late 1960's people have become alarmed with the danger of pollution. Air, water, and soil are necessary for existence of all living things. But polluted air can cause illness, and even death. Polluted water kills fish and other marine life. On polluted soil, food can not be grown.
