Well, we are all hearing about global warming these days very frequently. This global warming is the effect of increased concentration of GHG (Green House Gases) due to burning of fossil fuels & deforestation.

The temperature difference between the last Ice Age and now is about 5° Celsius. Average world temperatures rose by 0.7° Celsius in the 20th century, according to the U.N.’s Intergovernmental Panel on Climate Change (IPCC). Global average temperature is forecast to rise 4°C (7.2°F) toward the end of the 21st century, and this is a mere 90 years away. Even if began today, and stopped most of our greenhouse gas emissions overnight, we would still see a temperature rise of around 2°C (3.6°F) by 2090-2100.

Metal fabrication refers to the processes and activities that can alter the shape of the metal by removing or deforming the metal from it. There are several processes that play an important role in the manufacturing of complex metal parts. After cutting the metal stock it is cut and shaped as per desired specifications while it is cooled to take the specified shape. However, most of these methods have impact on the environment. Metal working fluid and scrap contains dangerous constituents and toxic substances that may end up in solid waste, wastewater and air emissions.

Fluid substitutions like process modifications, vegetable based fluid like maintenance and operation changes, low-volume applicators including the use of sumps, disinfectants and sumps can all decrease the production of waste from metal working fluids.

Water pollution is a major problem in the United States. All over the world, water pollution is increasingly becoming a major public health concern as statistics shows rising level of pollution in major waterways.  Since sustenance of life on earth depends on water, water pollution is a major threat to life on earth.  As more waterways become polluted, the amount of clean water available for domestic use is decreasing at an alarming rate.  Most source of pollution emanates from human effort to make their lives better, but animal, on land and in ocean, becomes the major culprit of the rising level of water pollution. For example, recent studies have revealed that whales have a higher concentration of carcinogenic chemicals which are endangering their lives.  Water pollution is particularly dangerous because all these chemical pollutants may end up in our bodies, which will come with devastating health consequences.

Lead is one of the common and dangerous water pollutants. Lead pollution is made worse by the fact that it may be difficult to monitor as the sources cannot be easily detected.  It cannot be detected unless complex laboratory testing is carried out, since it cannot be smelt or tasted. In most countries, lead pollution is major problem that is affecting the quality of drinking water.
