0000001453 00000 n Wastewater discharged from factories and establishments is often discharged into public water areas such as rivers, and sometimes reaches underground water. Aquatic organisms are often sensitive to even small temperature changes. Humans who come in contact with polluted waters and affected fish can also experience harmful symptoms. \_ρ+�����o���� �W�7�k$d���`-샃p=���� ��G��s�����>���!����(q7q�x�x�����o���"�!

Once the oil is in the water, there are three types of methods for dealing with it: 1. Inadequate collection and treatment of wastewater, which contaminates surface waters and aquifers and threatens public health and the environment. d) … To increase air emissions, water pollution and land contamination are the main objectives of environmental pollution. endstream endobj 235 0 obj <> endobj 236 0 obj <>/Type/Page>> endobj 237 0 obj <> endobj 238 0 obj <> endobj 239 0 obj <>stream Water pollution includes any contaminant that gets into lakes, streams, and oceans. Real estate prices along the Gulf have declined precipitously. By linking the exposure to health outcomes, new exposure-response relationships are determined of health effects for different popultion Groups (e.g. When the relief wells entered the original borehole, specialized liquids were pumped into the original well to stop the flow. A surprising number of beaches are closed because of possible health hazards each year. xref Freshwater and ocean pollution are serious global problems that affect the availability of safe drinking water, human health, and the environment. This means that one or more substances have built up in water to the extent of causing problems to people, animals and plants. It was not until July 15, nearly three months after the accident, that the well was successfully capped. Darker blue regions of the oceans indicate that organic particulates are high and may lead to a dead zone. A large proportion of the fish we rely on for food live in the coastal wetlands or lay their eggs there. Islands and marshlands around the Gulf have many species that are already at risk, including four endangered species of sea turtles (Figure below). Radioactive substances from nuclear power plants, medical and scientific sources. .�O7s�2�tN�K Add maps, tables, and bright colors to catch reader’s attention. x�b```�"VƝ� cg`a����z�ۤ��5Z"�3��CxBZ�0b�2! What is the leading cause of death for children around the world? Distinguish between oligotrophic and eutrophic lakes and explain how humans induce artificial eutrophication. Objectives of Water Pollution Control... Systems designed to remove waterborne wastes from communities, industries, and so on while protecting the health of people and the environment. Mercury, a potent neurotoxin, has been flowing into the San Francisco Bay since the Gold Rush Era. Removal: Oil is corralled and then burned; natural gas is flared off (Figure below). About 50% of all infectious diseases are caused by water pollution. A dead zone is an area of hundreds of kilometers of ocean without fish or plant life (Figure below). 0000000016 00000 n It is an Act to provide for the prevention and control of water pollution and the maintaining or restoring of wholesomeness of water for the establishment, with a view to carrying out the purposes aforesaid, of Boards for the prevention and control of water pollution, for conferring on and assigning to such Boards powers and functions relating thereto and for matters connected therewith. Describe why conserving water and protecting water quality is important to human health and the environment. Water pollution is a major environmental issue in India. Working on oil platforms is dangerous and workers are exposed to harsh ocean conditions and gas explosions. Chapter 10 - Framework for Water Pollution Control 10.1 Introduction 10.2 Initial analysis of water quality problems 10.3 Establishing objectives for water pollution control 10.4 Management tools and instruments 10.5 Action plan for water pollution control 10.6 References Case Study I - The Ganga, India I.1 Introduction I.2 The Ganga river Chemicals, such as sulfur, from burning fossil fuels. 0000022044 00000 n Photo by CC0 on Canva. age, education, ethnicity, gender, lifestyle, and working life vs. retirement conditions) related to air pollution for the individual chemical air pollutants. Burning the oil can reduce the amount in the water. Most rivers, lakes and surface water in India are polluted due to industries, untreated sewage and solid wastes. What Is Air Pollution? The toll on wildlife is felt throughout the Gulf. How does water pollution contribute to water shortages? 0000027036 00000 n Rivers that drain regions where human population density is high and where crops are grown create dead zones all over the world (Figure below). 0 Water pollution contributes to water shortages by making some water sources unavailable for use. Where are most of the dead zones located? Decomposition uses up all the dissolved oxygen in the water. In underdeveloped countries, raw sewage is dumped into the same water that people drink and bathe in. � �{��������G�+���_�J���>��OBCl#��u����/xй%@@��BO�8�~��?��TA#tB�� p^������įI7� �$ߤ\T�JSߧ{��������`5X��f�����x 0000073475 00000 n Tourism is down in the region as beach goers find other ways to spend their time.
