Soil acidity/alkalinity is essential for farmers determining the profitability of planting certain types of crop in certain areas. Some plants grow well in slightly acidic soils while others prefer an alkaline environment.  While we think of the air around us as neutral, the atmosphere naturally contains acidic oxides of carbon nitrogen and sulphur. The concentrations of these acidic oxides have been increasing since the Industrial Revolution. Identify oxides of non-metals that act as acids

percent more for waste like zinc ash. Many other developing nations in Africa and Southeast Asia have stopped buying these hazardous wastes. According to Greenpeace, an international environmental organization, more than 100,000 tons of potentially toxic waste entered India in 1998-1999. Greenpeace has documented imports of more than 100,887 tons of hazardous and potentially hazardous wastes into India between 1998-1999. These include zinc ash and residues, used batteries, brass dross, copper cables

The Jasper County area has a history of lead and zinc mining dating back to the early 1900s. The first lead mining was approximately two miles east of Joplin at Leadville in 1848, with the Granby area as the largest Missouri producer from 1850‑1870 ("Missouri lead mining”). In 1850, commercial development

INTRODUCTION Health is always considered the most important factor for human’s lives. Without health, we cannot do anything. There are many factors in daily activities that can affect your health such as food, drinks, soil, water, air, or we can say the environment around us. Because the environment plays a vital role to human’s’ health, we are trying to do everything to conserve the environment. However, there are still some activities that we might think they are safe for us and the environment;

Proponents of a world-scale hydrogen economy argue that hydrogen can be an environmentally cleaner source of energy to end-users, particularly in transportation applications, without the release of pollutants like particulate matter and carbon dioxide. However hydrogen continues to have technical obstacles associated with it, including storage issues, due to the fact that hydrogen has a high energy density by weight, but has a low energy density by volume when not highly compressed or liquefied.

electrically based technologies were discovered. The nineteenth century began with a debate between Luigi Galvani, and Alessandro Volta regarding the source of electricity in Galvani’s famous frog experiment. These debates lead to the invention of the battery by Volta, and the invention of Volta’s. Volta’s discoveries would lead the way for Ohm’s law several years later. However, before that discovery was made Hans Christian Ørstead discovered electromagnetism, which was then used by André Marie Amperè
