Essays on Leaching

The environment is everything that surrounds us. It involves not only the natural elements that the word “environment” entails but also people and the man-made components of the world. Nor is the environment restricted to the outside, it also involves the indoor sections in which we live and work. The environment, therefore, is much more than simply the ozone layer and the ocean. It is the soil, air, water, lands, animals, houses, restaurants factories and all that they contain. Anyone who uses pesticides indoors or outdoors, in a city or a country, needs to consider the way that pesticide ...

Introduction

In 2014 Flint Michigan found itself captured in the national headlines after high levels of trihalomethanes (THMs) and lead concentrations were found in the water system. This was after a terrible decision was made by the Flint Michigan city council of switching the water supply from a Detroit plant treated water system to the local Flint River water supply. The decision was made because the city council officials believed that the new proposed water system would assist in saving a lot of money little did they know that they would cause a significant problem to the society. Soon after ...

Increasing concentrations of nitrogen in the environment, a phenomenon called as nitrogen saturation occurs when the inorganic nitrogen levels exceeds the demand by organisms and plants. Increased concentrations of nitrogen have detrimental impact on the air quality, owing to the oxidizing capacity of nitrogen oxides and their function in the formation of ozone layer . Excessive nitrogen deposition causes an increase in foliar nitrogen content, which subsequently leads to increase in tree growth . Other negative effects on the ecosystem are frost-hardiness in conifer trees in the presence of large doses of nitrogen. Excessive nitrogen concentrations may also lead to tree ...

As seen in the excerpt above, the process of gold mining is associated with very adverse impacts on the natural environment. The impacts that the mining causes on the environment later affects living organisms and human beings. These results have made it necessary for the government, nongovernmental organizations and stakeholder in the mining industries to come together and mitigate the adverse effects caused by the process of gold mining. This paper discusses the role of the government and nongovernmental organizations in reducing the negative impacts that gold mining causes on the environment (Angell & Klassen, 1999). The government is the ...

Metallurgy

Definition of Metallurgy

Metallurgy is "the science and study of the behaviors and properties of metals” (Tom Bertone Consulting, 2012) and the procedures involved in the extraction of metal from ore. In particular, it deals with the properties of metals and alloys. Metals are characterized as having the capability of conducting electricity and heat (“Metallurgy,” 2011). They are hard and are dense under room temperature. Alloys, on the other hand, are combinations of metals. An example of an alloy is steel, which is a combination of carbon and iron, although vanadium and chromium may also be added. Other examples ...
