Microbiology and Process Analysis laboratory 25/10/2013 Group 1 Microbiology laboratory Abstract The lab exercises were divided into three different analysis; microscopy‚ soil microbiology and bacterial growth. The main aim of laboratory work with Escherichia coli and soil sample was to introduce students to bacterial growth in pure culture and soil microbial flora. The experiment of bacterial growth in pure culture using optical density

Water Polution definiton: Water pollution is the contamination of water bodies (e.g. lakes‚ rivers‚ oceans‚ aquifers and groundwater). Water pollution occurs whenpollutants are directly or indirectly discharged into water bodies without adequate treatment to remove harmful compounds. Water pollution affects plants and organisms living in these bodies of water. In almost all cases the effect is damaging not only to individual species and populations‚ but also to

CHAPTER 1 INTRODUCTION‚ OBJECTIVES AND OUTLINE OF THE THESIS -49- -50- Abstract As marine environments are under increasing anthropogenic pressure‚ there is a need for decision support systems (DSSs) and management tools that allow to tackle some of the environmental problems associated with this pressure and to allocate the different uses in a sustainable way. Most marine management tools are built around the Driver-Pressure-StateImpact-Response (DPSIR) framework‚ where indicators

WATER POLLUTION IN CHINA River like blood in Roxian‚ Guangxi About one third of the industrial waste water and more than 90 percent of household sewage in China is released into rivers and lakes without being treated. Nearly 80 percent of China’s cities (278 of them) have no sewage treatment facilities and few have plans to build any and underground water supplies in 90 percent of the cites are contaminated. Water shortages and water pollution in China are such a problem that the World Bank

Science Folio Chapter 5 B6D5E1 Title: Importance of maintaining the cleanliness of air Introduction The atmosphere of Earth is a layer of gases surrounding the planet Earth that is retained by Earth’s gravity. The atmosphere protects life on earth by absorbing ultraviolet solar radiation‚ warming the surface through heat retention (greenhouse effect)‚ and reducing temperature extremes between day and night. One of the most important factors drawing international attention which is

Land degradation will remain an important global issue for the 21st century because of its adverse impact on agronomic productivity‚ the environment‚ and its effect on food security and the quality of life. Productivity impacts of land degradation are due to a decline in land quality on site where degradation occurs (e.g. erosion) and off site where sediments are deposited. However‚ the on-site impacts of land degradation on productivity are easily masked due to use of additional inputs and adoption
