industrialized world is facing today is the contamination of soil‚ groundwater‚ sediments‚ surface water and air with hazardous and toxic chemicals. The long-term production and use of different petroleum derivatives have caused widespreadcontamination of soil around facilities handling them (Barbee et al.‚ 1992). The need to remedy these contaminated environments has led to the development of a number of technologies such as bioremediation (Head‚ 1998)‚ that aim at the destruction and detoxificationof

Screening and identification of rhizobacteria isolated from heavy metal contaminated soils INTRODUCTION As a result of human activities such as mining‚ agriculture and industrial activity‚ heavy metal pollution has become one of the most serious environmental problems today. Elevated levels of heavy metals not only decrease soil microbial activity and crop production‚ but also threaten human health through the food chain. Soil microorganisms can degrade organic contaminants‚ while metals need immobilization

Soil Porosity and Permeability GEO 101 LAB – Earth Science July 26‚ 2014 Soil Porosity and Permeability The focus of week three’s lab in Earth Science is to figure out the porosity and permeability of four different soil types: gravel‚ sand‚ potting soil‚ and soil from my back yard. This lab is designed to look at the porosity and permeability of these four soil samples. Porosity is basically the measure of how much of the soil volume is open space. Permeability is the measurement of how long
