Contaminants Literature Reviews Samples For Students

Introduction

Many countries across the world are faced with the problem of water and soil contamination. The contaminations are caused by industrial effluents, military actions and agricultural activities among others. Human carelessness and ignorance also contribute significantly to water contamination. As a result, new biological, chemical and natural activities have been invented in order to control water contamination. One of the most successful measures used in control of water contamination is phytoremediation. It involves the use of plants to absorb pollutants from contaminated water found on the surface of the land and in the soil. This paper discusses the biological ...

Introduction
The Tokohuma earthquake in Japan occurred in 2011 on March. It occurred in the Pacific Ocean where it caused a huge tsunami that was very devastating. The earthquake was the largest ever recorded in Japan and the fourth largest in the world. It produced a tsunami of sixteen metres high. What’s more is that the tsunami hit Fukushima nuclear power plant in Japan that caused an explosion which produced radioactive contamination which spread over Japan and the surrounding areas affecting the air, soil as well as the water. This disastrous event had adverse effects on Japan as a country ...

Introduction

Pharmaceutical companies should create and follow a standard operating procedure by implementing a cleaning validation to ensure future patient safety. Validation has received great attention by the FDA in recent inspections. Manufacturers must validate their cleaning process to ensure compliance with GMP regulations 1. One of the main keys in the manufacturing of dosage formulation is to develop cleaning procedures that will remove all types of residues from the equipment and containers. The goal of Cleaning Validation is to ensure effectiveness in cleaning equipment, and to prevent pollution and cross contamination of drug products to ensure the quality, safety; efficacy and ...

Requirement for the Manufacture of Drugs concerning Public Safety

Abstract
The study will focus on pharmaceutical companies’ standard operation procedures. More in depth, the study will determine if cleaning validation and verification is a successful way to keep the quality of manufactured drugs at a high standard. The importance of the validation of a sterilization process will be examined. The study will list reasons for validation of sterilization through a set of regulatory expectations put in place by the FDA.
The regulatory expectations of the FDA will support the methods and analysis used to conduct this study. The study will also examine the success and failure of cleaning validation through ...

Introduction:

Clean non-polluted water is a major basic requirement for all the living things. Nowadays, its availability becomes a major problem in the ecosystem. This problem is expected to increase in the future due to population growth and industrialization processes. The processes discharge of domestic, industrial and agricultural wastes contribute largely to the contamination of existing natural waters in the environment. Therefore, at the present moment, it is important that the pathogens and pollutants are completely removed from the waste water to cater for the needs of domestic use, industrial use, and irrigation purposes. This paper discusses two processes of oxidation and ...

Introduction

Membrane filtration is a technique used to separate a liquid from any particles present in it. In membrane filtration, a liquid is passed through a semi-permeable membrane. The size of the pores on the membrane determines its permeability thereby enabling the membrane to act as a barrier to all particles larger than the pore sizes. Different approaches and systems can be employed in membrane filtration depending on the type and capacity of the liquid being purified but the overall goal is to obtain a clean liquid. Membrane filtration can be used in the treatment of wastewater, filtering milk during its processing among other applications. This ...

Introduction

Quality of air is a determinant in the quality of life, indoor air is important as people spend on average 80-90% of their lives in door (WHO, 2007). Indoor air quality began a long time but only been a health concern decades ago when awareness of contaminants presented in the air. The problem begins when the construction of building are highly insulated to conserve energy, which caused a trap to air intoxicants inside the building (E. Willard, 2005). This causes the exchange of outdoor to indoor to lessen and therefore the indoor air pollution builds up.

Indoor air quality is a complex issue as ...

Literature Review on Fracking

Introduction
The extraction of natural gas has been seen the much-needed reprieve in the face of increased energy demands globally. The natural gas present unexploited energy reserves that can be used to meet the energy deficits in the countries where there are natural gas deposits. Its extraction requires the use of advanced technologies. Fracking the main technology used in the exploitation of natural gas from the rocks beneath the earth’s surface where it is trapped. The biggest proportion of the new wells for the exploitation of natural gas (90%) utilizes hydraulic fracking as the technology of choice. While ...

Smart water networks take advantage of real time data, pumps and other essential distribution points to automate the process control schedules and support real time operations decisions. It is well understood that the drivers for smart water networks is not resistible. There is a compelling need to develop smart water and energy efficient systems that are at par with the rising demand and the diminishing water resources. The fact that infrastructures are rapidly deteriorating and the fact that water loss and leakage are relentless means that there is a need for intelligent systems that would detect, report, and prevent associated water ...
