Introduction

A quarry is like an open pit mine from where minerals are extracted that are mostly used in the construction of buildings and civil engineering works. Quarrying is a part of mining but is slightly different as it has a close connection with the society because different builder of a region requires material that is extracted in order to complete their work. There are not many restrictions for quarrying as it is open for all the contractors. Due to this reason all the managers and developers at different levels need to ...

Forces of nature shape the surface of the earth, but there are also the manmade industries that can largely reform and alter the landforms. Quarrying is also one of the men invented industry that has a different impact on the people and the environment at large. Focusing on the problems associated with the environmental effects, it can largely impact the health of the people through inhalation of dust and listening to loud, noisy sounds. Indirect problems of the quarrying include the calamities that can cause greater damages such as through land sliding and flash floods. Major negative effects of ...

Abstract

Purpose: To determine the extent to which the silica levels are above the safety levels outlined by the Occupational Safety and Health Administration in areas proximal to the natural gas development sites. Background: While studies have shown that the silica levels in the hydraulic fracturing sites are very high, there is paucity of information as to how far away from the sites the silica levels in the air are dangerously high. Methods: The study will employ a longitudinal design with the data being collected over a ten-year period. The samples will be collected in a linear direction. The samples ...

Introduction:

Occupational exposure to silica crystals has long been identified and recognized in most of the industries. There are various industries that involved the silica dusts, where some are highly exposed beyond the threshold limits for the substances. The problem with the occupational exposure of workers to silica crystals are often not taken seriously be employer and employee alike. Exposure to silica in the occupational environment results to health effects such as silicosis and other related diseases. People who are working with these crystals are prone to respiratory effects as well. There is a problem in the safety and health ...

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 ...
