ENVIRONMENTAL CHEMISTRY - G R O U P 2 -  MEMBERS Dan Japona Eliza Fe Luib Janine Bernandez Jeah Gegayon Josephine Albano Prency Rj Esmeralda Marjorie Galgo  WHAT IS ENVIRONMENTAL CHEMISTRY? it deals with the study of reactions, sources, transport, and effects, along with the fates of all the chemical species present in the soil, water, and air environments, ENVIRONMENTAL COMPONENTS ATMOSPHERE HYDROSPHERE LITHOSPHERE BIOSPHERE Presentation Design  ATMOSPHERE The layer of gases surrounding the Earth. Environmental chemistry focuses on air pollution, greenhouse gases, and the role of chemicals in climate change. HYDROSPHERE Includes all water bodies like oceans, rivers, lakes, and groundwater.  LITHOSPHERE Refers to the Earth's crust and soils. It includes studying soil contamination, nutrient cycling, and heavy metal pollution.  BIOSPHERE Encompasses all living organisms. This involves understanding bioaccumulation (chemicals in organisms), toxicity, and ecosystem health. air pollution water pollution TYPES OF ENVIRONMENTAL POLLUTION soil pollution Rimberio Co AIR POLLUTION The air we breathe can be affected by pollution from factories, cars, and other sources. Harmful gases, like carbon dioxide (CO₂) and methane (CH₄), trap heat in the atmosphere, causing the planet to warm up, which we call global warming.  CAUSES OF AIR POLLUTION Burning Fossil Fuels Burning fossil fuels releases many pollutants into the air. These pollutants include carbon monoxide, carbon dioxide, nitrogen dioxide, and sulfur dioxide.  BURNING FORESTS Millions of acres of forest have been cut and burned to make way for farming. Burning trees produces most of the same pollutants as burning fossil fuels.  AUTOMOBILES The gases emitted from vehicles such as jeeps, trucks, cars, buses, etc. pollute the environment. These are the major sources of greenhouse gases and also result in diseases among individuals.  AGRICULTURAL ACTIVITIES Ammonia is one of the most hazardous gases emitted during agricultural activities. The insecticides, pesticides and fertilizers emit harmful chemicals in the atmosphere and contaminate it.  WATER POLLUTION Water pollution occurs when harmful substances —often chemicals or microorganisms— contaminate a stream, river, lake, ocean, aquifer, or other body of water, degrading water quality and rendering it toxic to humans or the environment.  CAUSES OF WATER POLLUTION Sewage and wastewater Used water is wastewater. It comes from our sinks, showers, and toilets (think sewage) and from commercial, industrial, and agricultural activities (think metals, solvents, and toxic sludge).  OIL POLLUTION Big spills may dominate headlines, but consumers account for the vast majority of oil pollution in our seas, including oil and gasoline that drips from millions of cars and trucks every day.  SOIL POLLUTION Soil pollution happens when harmful chemicals like pesticides (used to kill bugs on crops) or fertilizers (used to help plants grow) get into the ground.  CAUSES OF SOIL POLLUTION Pesticides are chemicals designed to kill or control pests, including insects, weeds, and fungi, their excessive and improper use can contaminate the soil.  IMPROPER WASTE DISPOSAL Improper waste disposal, including the dumping of solid waste and hazardous materials in landfills, is a significant cause of soil pollution.  MINING ACTIVITIES Mining activities, such as the extraction of minerals and metals from the earth, can cause significant soil pollution.  CHEMICAL REACTIONS AND THEIR ENVIRONMENTAL IMPACTS Ozone Depletion Chemicals like chlorofluorocarbons (CFCs) react with ozone in the stratosphere, causing the depletion of the Acid Rain ozone layer. The ozone layer Greenhouse Effect Sulfur dioxide and nitrogen protects Earth from harmful Greenhouse gases like carbon oxides react with water in the ultraviolet radiation. dioxide, methane, and nitrous atmosphere to form sulfuric oxide trap heat in the acid and nitric acid, which fall to atmosphere, contributing to the ground as acid rain. Acid global warming. This can lead to rain can damage forests, lakes, climate change, sea level rise, and and buildings. extreme weather events  WHY IS - it understands how chemicals ENVIRONMENTAL behave in the environment, it find ways to reduce pollution, protect CHEMISTRY nature, and make sure that humans, animals, and plants can IMPORTANT? live in a healthy world. P o l l u t i o n c o n t r o l A n d R e m e d i a t i o n Presentation Design - FILTRATION AND SCRUBBING: REMOVING POLLUTANTS FROM AIR OR WATER BY TRAPPING THEM IN FILTERS OR USING SPECIAL SOLUTIONS TO CLEAN THEM. - CATALYTIC CONVERTER: A DEVICE IN CARS THAT CHANGES HARMFUL GASES FROM THE ENGINE INTO LESS HARMFUL ONES. WASTE WATER TREATMENT: CLEANING DIRTY WATER SO IT CAN BE SAFELY RELEASED INTO THE ENVIRONMENT OR REUSED. - BIOREMEDIATION: USING LIVING ORGANISMS, LIKE BACTERIA, TO BREAK DOWN AND CLEAN UP POLLUTION. - PHYTOREMEDIATION: USING PLANTS TO ABSORB OR REMOVE POLLUTANTS FROM SOIL OR WATER. - SOIL WASHING: USING WATER AND CHEMICALS TO REMOVE CONTAMINANTS FROM SOIL. THANK YOU
