Pollution control in recycling of lead batteries Introduction: Lead is one the most successfully recycled material in the world. Over the years lead recycling has greatly matured as a result over half of the lead produced and used each year throughout the world has been used before in other products. Today over 80% of the lead is used in the making of lead-acid batteries which are theoretically speaking 100% recyclable. Lead recycling however has one critical problem‚ lead and the many of the

AIR QUALITY IMPACT ASSESSMENT REPORT OF THE PROPOSED BASE TRANSCEIVER STATION (BTS) October‚ 2012 1.0 Introduction The sources of ambient air pollution‚ especially in urban environments‚ are often quite diverse. These sources can be broadly classified as stationary‚ mobile and area emission sources. Emissions of pollution from these three classes of sources typically result in complex spatial and temporal distributions of ambient air pollution concentrations. Emission inventories form

1.) Explain why the following substances are added to soil by gardeners and farmers. a.) Lime CaO It increases the pH of soil.Soil that is too acidic presents two different problems for crops. First‚ the amount of necessary minerals in the soil such as potassium and calcium decreases. Second‚ aluminum and manganese levels increase to potentially toxic levels below a pH of roughly 5.5.Calcium oxide‚ addresses the problem. It reacts in water to release calcium ions and hydroxide ions‚ which raise

NO2 is of most concern; it is a highly reactive gas emitted from vehicles and power plants that also affects the respiratory system of sensitive people‚ such as elderly and children. Compliance with current NO2 standards has ensured the protection of individuals once affected by this highly volatile gas. Air pollutants usually do not affect only the air‚ but water and land as well. CO2 and NO2 also seep into the water and soil‚ altering plant and
