Pollution And Its Consequences

June 30th, 2015 -- Posted in Environment | No Comments »

Any contamination of the resources, natural or artificial, can be called as pollution. There were no such issues in the ancient times when the man was content with what he had, and he relied on the natural resources. With the advent of technology and owing to the population growth and civilization, the demand and consumption have increased manifold necessitating the invention of alternatives and substitutes. As a result, the chemicals and synthetics are extensively used in every sphere of daily life. Pollution takes place continuously in different ways, affecting our environment and life. In order to understand this man-made hazard, the common types of pollution and their consequences are listed hereunder.

Air pollution: The most critical type that directly harms our respiratory system. Air is polluted by the entry of chemicals, dust, heat and noise from various sources. The smoke and gaseous effluents emanating from the factories, vehicles, power plants and other installations like the air-conditioners and refrigerators form the major source of air contamination. The invisible radiations from the nuclear plants and the microwave towers are the hi-tech pollutants silently harming all life forms. The insecticide sprays made in the agricultural farms affect the people living in the vicinity. Smoking of tobacco products also pollutes the air.

Water pollution: This occurs in the water held in the surface and underground structures. The flow of sewerage water and effluents from various sources like buildings, factories, etc. contaminates the water bodies such as rivers, ponds, tanks and dams. The seepage of effluents and wastes from tanneries and chemical industries spoils the water aquifers. Excessive of groundwater results in the sea water intrusion. Oil and chemical spills from marine vessels, and fallen aircraft cause the destruction of the coral reefs and other flora and fauna in the oceans. Pumping of waste and fuels leaks from the nuclear reactors make the seawater unsafe for its inhabitants.

Land: The effluents released by different manufacturing and residential units stagnate and affect the quality of the soil. Use of fertilizers and pesticides renders the soil unfit for farming operations in the long run. Even the construction of dwelling units is impossible when the soil strata get affected by the surface pollution.

Heredity: The development of genetic engineering and medical techniques has altered the basic nature of many things around us. Plastic surgery, Liposuction, Test-tube baby, Cloning, Stem-cells, GM crops, etc. are examples to quote.

Consequences of Pollution: The effects of pollution are of the immediate and far-reaching nature, and are innumerable. The important ramifications are listed below.

1) The health concern is the foremost. Genetic mutation, physical deformities and new diseases and disorders are the fallout of the toxins, new pathogens, heat, and radiation.

2) Climatic change causes the glaciers and continental icebergs melt, leading to the inundation of the land areas from the surging sea level.

3) Earth’s heritage is gradually altered and lost. Many species of plants, insects, and animals become extinct. For instance, Sparrow once a common sight in many places has become a rarity.

4) Degradation of soil and water quality leads to reduced land availability for food production and consumption.

5) Life on earth is becoming precarious though its standards said to be high.

Adopting the organic farming and reliance on the Nature for sustenance alone can save from the vagaries of pollution. However, this is possible only if we adopt a change in the mindset to live within our means by controlling the ever-growing aspirations.

Vapor Intrustion – what is it?

June 19th, 2015 -- Posted in Environment | No Comments »

Vapor intrusion occurs when volatile chemicals migrate from contaminated groundwater or soil into a building. Volatile chemicals can emit vapors that may migrate through the subsurface and into indoor air spaces of overlying and nearby buildings in ways similar to that of radon gas seeping into homes (see text box). Most volatile chemicals are volatile organic compounds (VOCs), but some semivolatile organic compounds (SVOCs), such as petroleum products, and inorganic constituents, such as elemental mercury and radon, can emit vapors leading to vapor intrusion.
In extreme cases, the vapors may accumulate in homes and other occupied buildings to levels that may pose near-term safety hazards (e.g., explosion), acute health effects, or odor problems. Typically, however, the chemical concentration levels with vapor intrusion are low, and the odor unnoticeable. Depending on site-specific conditions, the vapors may not be present at concentrations detectable by analytical instruments. In buildings with low concentrations of volatile chemicals, the main concern is whether or not the chemicals pose an unacceptable risk of chronic health effects due to long-term exposure to these low levels. A complicating factor in evaluating the potential risk from chemical exposure due to vapor intrusion is the common presence of some of the same chemicals from sources with the building (e.g., household solvents and paints, gasoline, drycleaned clothing, and cleaning agents) that may pose, separately or in combination with vapor intrusion, a significant human health risk.

Vapor intrusion is a standard consideration during investigations at hazardous waste sites, especially those related to the Resource Conservation and Recovery Act (RCRA); underground storage tanks (USTs); and the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA or “Superfund”).

Keeping Water Clean With Turbidity Curtains

June 11th, 2012 -- Posted in Environment | No Comments »

Nowadays, it is becoming increasingly common for construction projects to be built alongside water. These locations are popular for many types of buildings, from apartment blocks to vacation homes. Yet building close to bodies of water can result in negatively affecting the water. This is why floating turbidity curtains should be employed whenever work will be carried out near to water. The overall goal being to prevent anything harmful from contaminating the water and in turn potentially ruining living organisms and plants.

Silt curtains, also known as silt barriers, provide a multitude of benefits to the environment. Once installed, there is no reason to worry about debris spoiling the surrounding water at all. It is important to understand that small amounts of debris will not cause detrimental harm to the water, as usually the water itself can quickly correct this issue and return to its natural state. However, when these quantities of debris begin to increase, the water alone cannot resolve the situation, and certainly not efficiently. Read the rest of this entry »

Green power applications: a solution for the environment?

February 21st, 2012 -- Posted in Environment | No Comments »

When thinking about environment, one of the most delicate subject is related to the energy we all use. Lately, specialists have found several alternative methods in order to minimize the pollution. Green power application seems to be one of the best ways to replace normal electricity. For example, green power application refers to renewable energy, which is considered as non-conventional one. Solar energy, wind energy, bio-energy and hydropower are just a few types of energy included in the green power application program. There are special systems that convert natural forces into usable energy. There for, the wind, the Sun, the water, these are all elements can be used in order to create a new world.

Solar energy as part of green power applications program

Solar energy is a part of the green power application. The best part about it is that it can not end and it’s for free. There are certain regions in the world where people understood this is a perfect way to create energy, so the solar energy is used for everything. Even if there are some money to spend in the first place for the system that converts the energy to be built, the investment is completely worthy.Indiais one of the best examples to offer in this case.

Global warming – people’s responsibility

February 15th, 2012 -- Posted in Environment | No Comments »

Global warming refers to the increase of the temperatures and ice-melting due to several factors created by the human being. This has become a serious problem for people in general because everybody can see the effects through changes such as the seasons that can not be separated anymore or the level of the water from any sea. In the last 100 years the temperatures have increased with about 0.8 degrees. The Arctic region is the most dangerous because if the glaciers will melt, the world will change its appearance.

What effects can cause global warming?

In time, scientists have made research about the causes of global warming and the result leads to the fact that the human being is responsible. Greenhouse gases lead to wear thin the ozone coating. Combustion of fossil fuels in cars, factories and electricity production are very dangerous and affect the whole world. The principal negative gas is carbon dioxide, which is also called CO2. Also, global warming is caused by actions taken in the agricultural domaine: fertilizers are used in order to help some plants grow, but they affect people by causing changes, such as global warming.

How green are you ?

January 22nd, 2012 -- Posted in Environment | No Comments »

Everyone wishes for a green tomorrow but, in order to have that, shouldn’t we start working on it today (there is nothing we can do about yesterday, unfortunately)? Also, a green planet requires for each one of its inhabitants to live green. So I am asking you: how green are you?

There are plenty of articles written about how to have a ‘green’ house or, even better, how to have an entire city ‘green’. But it all begins from the persons. If we manage to adapt our habits and our way of thinking to a more healthy way of living, then we might be able to get together in a big ‘green’ city. But this requires a bit of effort from each one of us.

How can we do this? Well… Read the rest of this entry »

Eco cars or green vehicles

January 10th, 2012 -- Posted in Environment | No Comments »

 

Everybody heard lately about eco cars, but what is one exactly? Well, an eco car or green vehicle how people calls it, is a friendly vehicle with the environment because it produces less harm in comparison to the normal automobiles. This type of eco car is powered by alternative fuels which scientists worked at for a few years, in order to reduce negative effects on environment. In the eco car series are included the following: hybrid electric vehicles, plug-in hybrid electric vehicles, battery electric vehicles, compressed-air gas vehicles, clean diesel and others too. It seems that there is a solution for everything and responsible people have found some to replace the normal cars which produce a high level of pollution. Also, there are green cars with high fuel economy and the drivers don’t have to think that much about the costs of driving such a vehicle.

When and how did the first eco car appeared?

Everything began long time ago, when people were talking about the Stanley Motor Carriage Company, which produced Stanley Streamer from 1896 to 1924. Between 1832 and 1839 was invented the first crude electric carriage and soon electric cars began to appear in Europe due to the fact that they were quieter and smoother than other cars. By the end of XVII century, the idea spread in America too. Eco cars reappeared in the late 1950s and early 1960s and the first one came as the Vespa 400, produced in 5 years (1956-1961). There were 28.000 models sold that time. Several eco cars with small engines were designed in the 1960s, including the Austin Healey Sprite. Read the rest of this entry »

EU Battery Directive: Types of Battery Covered

July 19th, 2011 -- Posted in Environment | No Comments »

The Batteries Directive (91/157/EEC) was adopted by the European Union in March 1991. The Directive introduced restrictions on the use of mercury in most batteries and also encouraged the collection and recycling of disused batteries.

On the 26th September 2008, however, a new battery directive (2006/66/EC) came into force which repealed the previous Directive. The reason behind the change was that it was found that the majority of the objectives of the first Directive were not achieved as most portable batteries were still sent to landfill (although some countries did have efficient collection schemes in place) rather than being collected and recycled.

Portable

Portable batteries are used by both consumers and by industry. These are sold as individual batteries and also in equipment. Primary batteries reach end-of-life (when discharged) before the equipment and so many waste primary batteries will be available for recycling. Rechargeable batteries are sold as individual batteries or in electrical equipment and so many will reach end-of-life when the equipment’s life ends. As a result, the user will remove some and others would be removed by WEEE recycling schemes. Therefore any system for collection of portable batteries will need to account for all of these routes.

How to Recycle Metal and Metal Products

April 11th, 2011 -- Posted in Environment | No Comments »

The scrap metal industry is, admittedly, getting very popular, especially for amateurs (Which I suspect you may be). Don’t worry! I was too, but I wrote down these 10 simple things quickly, saving you some embarrassing moments!

    Know The Metals

    The metal scrap industry is full of all types of metals, of all types of grades, and every type of “flavour”. It is your job as a scrap metal “artist” to know the difference between red brass and yellow brass… (hint hint It’s the color!) but also much more subtle things like the difference between 304 and 316 stainless steel. You will learn very quickly by taking things to a scrap yard. Ask questions, and be curious! Scrap yard crew are the best people to ask, and should be more than willing to help.

How Sustainable Are Your Shoes?

March 9th, 2011 -- Posted in Environment | No Comments »

Ethical and eco fashion have become big news in recent years with plenty of coverage of the environmental and ethical impacts of clothes manufacture and waste. But shoes and their sustainability is something that is not considered so often.

Have you ever considered how sustainable your shoes are? As a fashion item, whilst we expect our shoes to look great and be comfortable and functional, they are often considered throw away products which are discarded after just a few wears purely because they have gone out of fashion. The most sustainable shoes are not only incredibly comfortable but are also well made so that they will last for a long time. Classic and versatile styles are also the most sustainable as they won’t go out of fashion.
