Suburbanization entails the shift of the human population from the urban centers to the suburban regions leading to a phenomenon known as the urban sprawl. Many Americans now opt to reside in satellite communities otherwise known as suburbs commuting to and fro their workplaces using automobiles. The NPR report provides a vivid example of a family that left the city to live in the suburbs to avoid the rising costs of accommodation. Although it appears as if the move by the household and millions of other American families is a wise choice financially, it has serious implications on the ...

National Ambient Air Quality Standards (NAAQS) gets set up by the EPA by the Clean Air Act. The six principle pollutants entail the photochemical oxidants, lead, carbon monoxide, ground-level ozone, sulfur oxides as well as nitrogen oxides. Regulation of surface level ozone reduces the impact and other pollution damages on crops. Likewise, photochemical oxidants prompted particular action from the commission under NAAQS to develop standards that controlled coarse and fine atmospheric particles in the air. Also, the oxidants had the ability to poison agricultural foods just like lead. Therefore, the optimal level for lead is now at 1.5 mew-grams ...

Fuel Cell Technologies in Passenger Cars

Fuel Cell Technology The last decade is characterized by the rapid development of research activity in the field of fuel cells, thus, creating the conditions for their uptake in electric systems. The basic fuel cells’ operating principle has been known for 150 years. However, a variety of technical and financial problems had kept them on the margins of technological applications (Brandon & Hart, 1999). The basic difference between a fuel cell and batteries is that while batteries store energy, fuel cells directly convert a fuel’s chemical energy into electricity by an electrochemical reaction (i.e. Without requiring combustion or movement ...

Definition of Coatings

Coating is the process whereby one material is used to continuously cover another surface. According to Dewo et al. (2015), coating is a surface modification approach that involves the addition of a new material onto the surface of a substance or element that is at risk of corrosion.

Formula: Rusting of Iron.

iron + oxygen + water ==> hydrated iron(III) oxide (RUST) 4Fe(s) + 3O2(g) + xH2O(l) ==> 2Fe2O3.xH2O(s)

Different Types of Coatings

The process of coating utilizes multiple films of coatings as primers and top layers. The purpose of each layer is particular; however, the layers often interact with one another (Özçam et ...

Relationships between society and nature have become much more complicated in the conditions of scientific-technical progress. People received the opportunity to influence the course of natural processes, have subdued the forces of nature, began to master almost all of the available regenerative and non-renewable natural resources, but to pollute and destroy the environment. Air pollution has remained the major problem in the modern society. It is defined as the introduction by man into the environment of substances or energy liable to cause hazard to human health, harm to living resources and ecological systems. (Tiwary, Colls, & Colls, 2010) Artificial (anthropogenic) ...

Literature review

In the history of the construction of sea structures in oil exploration, load and corrosion together with how those structures will be maintained have always posed a scientific nightmare. Chamberlain, Adam and other authors in a scientific journal illustrate that for a good design of an onshore structure, there should be a right proportion of the ingredients in order for the structure to give maximum life service. They all agreed that in order to achieve this, keen interest should be paid to the permeability, strength, and durability of the mixture. Finally, they added that for effective control of corrosion, ...

Air pollution impacts the human health and the environment in various ways - by direct and immediate threat (smog, etc.) to the slow and gradual destruction of the body's various life-support systems. In many cases, air pollution negatively affects the structural components of the ecosystem to such an extent that the regulatory processes are not able to return to their original state and thus the homeostasis mechanism fails. The atmosphere is the air shell of the Earth. Air quality involves the totality of its properties, reflecting the level of exposure to physical, chemical and biological factors on humans, plant ...

Geology of Mars

Similar to Earth, all of the planets, including Mars, are defined by geologic processes. Of course, these geologic processes and conditions differ among the planets depending on various factors, such as the relative distance to the sun, composition of the planet, vulnerability to impacts and collisions, etc. Of all the planets, Mars is the closest to Earth-like conditions (Head 1). On the surface of Mars, as well as all of the telluric planets, the most abundant minerals are silicates. On Mars, the origins of most of the silicates are of basaltic to andesitic basaltic. On its surface, the main ...

Introduction

Air pollution involves the introduction of particulates and other biological molecules in the atmosphere, resulting in the death of humans, other living things and damage to other resources such as crops. It involves the interaction of different pollutants which eventually affect the environment, health, and even the climate. These pollutants are emitted almost from all economic and social activities. The most cases of air pollutants are; Sulphur Dioxide, Nitrogen Oxides, Particulate Matter, Ozone, Ammonia, Non-methane volatile organic compounds, carbon dioxide, lead, heterocyclic, chlorinated hydrocarbons, phenol and Methane amongst others. Emission of many air pollutants has decreased across Europe as ...

The purpose of this research is to know the properties of oxygen and to prepare different oxides, acids and bases. Experiments Carbon is reacted with oxygen in order to form carbon dioxide. Sulphur is reacted with oxygen in order to form sulphur dioxide and calcium is reacted with oxygen in order to form calcium oxide. As calcium is metal, the formed metal i.e. the calcium oxide is a metallic oxide. On the other hand, as carbon and sulphur are non – metallic, therefore, the formed oxides i.e. carbon dioxide and sulphur dioxide are also non – metallic oxides. If non – metallic ...

Introduction

Air pollution is defined as the introduction of biological molecules, particulates, and other harmful substances into the air in sufficient quantities such that they cause damage to the health of living organisms including human beings, plants, and animals and may sometimes cause death. These pollutants may also cause harm to property resulting in corrosion of buildings and causing them to crumble or destroy the environment by introducing foul odors and reducing visibility. Two different types of air pollution exist: natural or artificial, depending on the causative factors. Air pollutants are also classified into primary and secondary sources. Primary sources ...

According to EPA (2016), environmental management involves the development of systems aimed at reducing environmental impacts of various activities. In the Brundtland commission report (WCED), sustainable development has been described as development aimed at meeting the current needs of the present generation. However, as the current generation focuses on meeting their own needs, their activities should not compromise the capability of future generations to also meet their own needs. Available evidence suggests that the future generation would have challenges meeting their own needs if the current generation fails to adopt sustainable practices. The sustainable development incorporates the triple line: ...
