Essays on Sulphur

Abstract

The ecological settings in an ecosystem change from time to time. The changes in the ecological settings are brought about by a plethora of factors. Through evolution, the organisms that live in the ecosystem also change to adapt to the aforementioned ecological changes. The adaptation of the organisms to the ecological changes yields variations because different organisms and even organisms of the same species are exposed to the elements to different levels. Man has a significant role to play in the ecological changes. Through his economic activities, the effect on ecosystems has been both positive and negative. Urbanization as ...

The laws meant that the Bowen plant of the Southern Company had to reduce the amount of sulphur dioxide released during the production of electricity. Prior to the enactment of the laws, Bowen’s sulphur dioxide emissions amounted to thirty tons an hour (Reinhardt 2). This amount translated to an annual emission of 262800 tons assuming 8760 hours in a year. Between 1995 and 2000 during the first phase of the implementation of the laws, the plant would only be allowed annual emissions of 254,580 tons of sulphur dioxide. This translates to hourly emissions of 29.06 tons (Reinhardt ...

Introduction

Globally, clean air is a critical resource for the general public health while a clean environment is one of the essential elements required for the establishment of sustainable societies. Human beings breathe the air around them and thus air pollution or any pollution manifested in any other form to the environment directly affects their overall health and wellbeing. This has the implication that public authorities at international, national and local levels have the responsibility of protecting the quality of the air through development of regulations that regulate the use of products and materials that have the potential of causing ...

Introduction

Mustard gas, or sulphur mustard is a chemical term for an agent that causes burning of the skin, respiratory tract and eyes. Mustard gas can be captivated into the body via ingestions, inhalation or by getting in touch with the school or students with the eyes or skin. Mustard gas is delivered in a vapour or liquid form, and it burns the skin, windpipe, eyes, and lungs. The physical result depends upon the exposure level and might appear after few hours or in some cases it is sooner. Although mustard gas is lethal in high volume, blister agents are ...

Jack London's ‘To Build a Fire’ takes place within the sub- freezing Yukon of Alaska. The stories protagonist is an unnamed man who, besides the admonition of an experienced old man of Sulphur Creek decides to brave the merciless elements to meet his friends at a camp. Alongside him is his companion a large wolf dog. Readers are introduced to the setting at the beginning of the story as it states “day had dawned cold and gray” he continues with the statement “there seemed to be an indescribable darkness over the face of things” (London 64). This presents as ...

Material extraction

The mining and extraction of copper has several impacts on the environment. The extraction of copper is done in several steps and process using different technologies and mechanisms. The copper element is extracted from its ore through heating the ore using carbon. This process releases carbon dioxide gas into the atmosphere. It is a well known fact that carbon dioxide gas is a greenhouse gas which result into global warming. The result of the extraction is copper full of impurities. The impure copper is then placed under further treatment to eliminate the presence of the impurities. In most cases, ...

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 ...

Travelling to another planet is referred to interplanetary spaceflight. The term is usually used when travelling to a planet within the same planetary system (Fisher 1). The human race has made tremendous strides in space exploration. Man has made it to the moon and back, which was a great achievement for science as well as the human race. Man may not have stepped onto another planet yet, but significant achievements have been made in interplanetary exploration. There have been explorations using probes that have flown by every planet in the solar system. The New Horizons recently flew by the ...

Purpose

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 ...

Charlotte Perkins Gilman was an outstanding American writer and a huge supporter of women’s rights that reflected in her literary works. One of her most famous one is the short story “The Yellow Wallpaper” that is written in the form of a diary of a young lady, who was diagnosed with a mental disease and spent a time living in a room with yellow wallpaper that led to her demise. The story can be viewed as semiautobiographical, as Gilman wrote it after she had a postpartum psychosis. In her story she uses figurative language to reveal the theme ...

Abstract

In most parts of the Arab countries, the limited resources of water pose adverse constraints to both the social and economic development, while also threatening the people’s livelihood. The available surface water keeps on declining, and the ground water over-pumping that goes beyond the natural recharge rates has continued to cause great negative impact in the lowering of water table. Over-pumping of ground water also increases ground water salinity, ground water depletion, and ecological degradation (SCENR 5). The outcome prompted the Qatar government to start regulating its water resources as a measure ...

As Shanghai embraces the 21st century, it faces more challenges – environmental, social and economic. Rapid urbanization and economic growth has led to a high growth in population in urban areas with deleterious effects on sustainability and environment. All the factors are really interconnected and though this growth has benefited Shanghai and its people – by reducing poverty and increasing home incomes; one needs to evaluate the other effects of this development. Old problems typically ...

History of the UK Oil & Gas Industry

It was in the year 1975 that Hamilton Brothers, a small entrepreneurial entity of the United States, which was working in the Argyle field, succeeded in bringing British oil ashore for the first time, and this was almost immediately followed by the BP excavation that resulted in huge quantities of oil being discovered in the Forties field.

Progress made by the industry since the 1970s

Oil discovery in the North, grew leaps and bounds as several other companies from other nations like the EU, United States and many other domestic UK firms leased out many sectors of the North Sea for excavating oil. Slightly around the late ...

Incineration is a modern combustion technology where harmful wastes are transformed into gases and incombustible solid waste (Hester & Harrison, 1994). It is commonly used in burning municipal and industrial wastes. During incineration, there are factors that affect the quantities and composition of gases emitted. In considering the incinerator design, operation, and waster properties, the factors are (Rand et al., 2000): physical and chemical properties of waste; Combustion efficiency; and residency time. Physical and chemical properties of waste determine the composition of gases emitted in the sense that if sulphur was a constituent in the waste, then the expected ...
