severely high level of air pollution. This pollution is caused by emissions from road traffic‚ industries‚ and the energy sector. In 2005‚ over 200 cities in Ukraine exceeded the levels established by the World Bank health standards for annual concentrations of at least one pollutant. Nineteen cities exceeded health standards for three or more pollutants by at least a factor of 10. In comparison‚ the air pollution levels in the Los Angeles area‚ which has the worst overall air quality in the United

Position Paper 1: Global Climate Change – Is climate change a natural phenomenon or caused by man? There has been some discussion and debate over the causes of global climate change and particularly‚ the causative forces that have contributed to the measured increase in the mean atmospheric temperature over the last several decades. Many researchers and climatologists have concluded‚ using climate modeling systems that the main cause is anthropogenic (man caused). Other researchers have

Air is the fundamental necessity for human survival. But now we can’t ensure the air we breathe is clean and pollution-free‚ because the oxygen we need is being seriously polluted by smokestacks of factories‚ exhaust of transport vehicles‚ chemicals‚ volcanic activities‚ and most of these pollutants are contributed by human factor. In the paper‚ I will be focus on the air pollution caused by heavy road traffic‚ which almost everyone would realized every day. The fact is that there are too much old

Acids vs Bases In chemistry‚ when some elements are mixed‚ the compounds that are formed can be classified depending on its characteristics‚ just like acids and bases. Acids are defined as compounds that donate a hydrogen ion‚ H+‚ to another compound. Bases are the chemical opposite of acids. They both are different in many ways. One way in which acids and bases differ is the pH and the pOH. The pH is a number used to denote the hydrogen-ion concentration‚ or the acidity‚ of a solution. In the

There are four major factors when it comes to nature causing climate changes; volcanic eruptions‚ ocean currents‚ earth orbital changes‚ and solar variations. There are three major factors when it comes to humans causing climate changes; transportation‚ deforestation‚ and fossil fuels to generate energy. Volcanic eruptions can cause the climate to change. When a volcano erupts tiny particles called aerosols shoot into the atmosphere. These tiny particles reflect solar energy into space and cool
