Acid rain is caused by sulfur and nitrogen compounds emitted from both natural and man-made sources reacting with water, oxygen, and hydroxyl radicals in the atmosphere to form acids. When the acids fall to Earth as rain, snow, fog, hail or dry deposition, it makes lakes and streams acidic. Acid rain damages trees and other vegetation, buildings and statues, and is harmful to aquatic organisms. It also leaches nutrients from soils. The main causes of acid rain are emissions of sulfur dioxide and nitrogen oxides into the air from coal burning power plants and other industrial processes, as well as natural sources like volcanoes. Acid rain is deposited through both wet deposition processes like rain and snow, and dry deposition

RTM I_biofilm
This document outlines a group project to model biofilms in two systems - a marsh and a pipe. For each system, the group developed a conceptual 1D model of the biofilm with key assumptions. The models include equations describing oxygen, nitrate and biomass concentrations over time, accounting for photosynthesis, aerobic respiration and denitrification. The models were implemented and results showed higher biofilm accumulation where nutrients were abundant.
Chemistry of Coal
This document discusses different types of pollution from coal burning and methods to reduce emissions. It defines pollution and asks the reader to name pollutants for air, water and land. When coal is burned, it releases nitrogen, carbon, hydrogen, oxygen, phosphorus and sulfur (NCHOPS) which form various air pollutants. These pollutants can produce acid rain when it rains. Methods to reduce NCHOPS emissions include preventing their formation during combustion and removing them from flue gases using various scrubber technologies. However, there are tradeoffs between pollution reduction and energy costs.

Continuous casting-tundish technology
This document discusses the process of continuous casting of steel. It begins with an overview of steel composition and the continuous casting process, which solidifies molten metal directly into final form. Most metals are produced this way, including over 500 million tons of steel annually worldwide. The document then describes the steelmaking processes of basic oxygen furnaces and electric arc furnaces that prepare the molten steel. It focuses on the design, functions, and importance of tundishes in continuous casting, which hold molten steel and facilitate inclusion removal before casting. Key aspects of tundish design like features, insulation, nozzle placement, and refractory lining application are explained.
Sources Of Air Pollutants
The main sources of air pollutants are both natural and man-made. Naturally, carbon monoxide is produced by methane oxidation and bacterial decomposition. Oxides of nitrogen occur through lightning and bacteria. Sulfur dioxide forms from volcanic activity and bacteria. Particulates originate from sandstorms, volcanoes and fires. Volatile organic compounds are emitted by vegetation, bacteria, and methane-producing animals. Man-made sources include fossil fuel and industrial combustion, vehicular exhaust, smelting, and petroleum extraction/refining which release carbon monoxide, nitrogen oxides, sulfur oxides, particulates, and volatile organic compounds into the atmosphere.
Mechanisms of reactions causing pollution
The document discusses the various mechanisms that lead to ozone depletion and acid rain formation in the atmosphere. It describes the roles of free radicals like hydroxyl, chlorine, and nitrogen oxides in catalyzing the breakdown of ozone through cycles like the HOx, NOx, and ClOx cycles. It also outlines the chemical processes through which nitrogen and sulfur oxides in the atmosphere are converted to nitric and sulfuric acids that cause acid rain.
Acid Deposition
Acid deposition, also known as acid rain, occurs when pollutants like sulfur dioxide and nitrogen oxides mix with water vapor and fall back to Earth as rain, snow, or other forms of precipitation with a pH lower than 5.6. There are two main types of acid deposition: wet deposition where the pollutants mix directly with precipitation, and dry deposition where gases and particles fall under gravity. Sulfur dioxide and nitrogen oxides undergo chemical reactions in the atmosphere to form sulfuric and nitric acids, the main contributors to acid rain. To reduce sulfur dioxide emissions, coal power plants in the US use flue gas desulfurization systems that can remove up to 95% of sulfur gases through reactions with lime

Outdoor air pollution comes from a variety of natural and human-made sources. Major pollutants include carbon monoxides, nitrogen oxides, sulfur dioxides, particulate matter, ozone, and lead. Photochemical smog forms when nitrogen oxides and volatile organic compounds react with sunlight. Acid deposition occurs when sulfur and nitrogen pollutants are transformed and deposited, damaging forests, soils, and aquatic life. Solutions involve reducing emissions through improved energy efficiency, pollution controls on industries and vehicles, and transitioning to cleaner fuels.

atmospheric chemistry
This document is an assignment submitted by Asma Sattar to Ma'am Sobia in the Department of Environment Science at GCUF.

Photochemical smog develops when primary pollutants like NOx and VOCs from fossil fuel combustion interact with sunlight. This produces secondary pollutants like ozone and PAN. For photochemical smog to form, sunlight, NOx, VOCs, and temperatures over 18°C are needed. Reactions between these pollutants produce the toxic components of smog. Acid rain forms from SO2 and NOx emissions reacting with water and oxygen in the atmosphere to produce sulfuric and nitric acid. This acid rain damages ecosystems and infrastructure. Topography and temperature inversions can trap smog near the ground.
