Some of these may assume an epidemic state. Presence of these chemicals at increasing levels is of great concern because of their known toxicity, mutagenicity and carcinogenicity. Streams at pH 3.0 implies the presence of 0.5 x 10-3 M H2SO4. 0.25-4.5 ppb). 25-125 ppb; D.D.T. malathion; Organochlorinc group e.g. We extract a lot of water from rivers and lakes around the world for our own needs. Water Pollution Control and Management. Pond Life and Pond Food Chain Science Project from Science Teaching Center. Water Pollution Control and Management: Clean water is essential for healthy environment to support life systems on this planet. Hard water results in scaling and even bursting of boilers and hot waste pipes through which it passes. Thus, soluble iron (I) and manganese (II) are oxidized to insoluble iron (III) and manganese (IV) compounds as an anaerobic water sample absorbs O2 from the atmosphere. Water isn't just used locally. Exploring Pond Life with Kids from Kids Activities Blog. The river segments upstream of Giddi and downstream of Bardhaman are much less significant in terms of water pollution. Pollution. Life was first originate in water. Paris green (Copper acetoarsenite) was extensively applied to pools in the tropics for controlling malaria transmitting mosquitoes. The sources of oil pollution are oil spill from cargo oil tankers on the seas, losses during off-shore exploration and production of oil, and leakage from oil pipe­lines crossing waterways and reservoirs. A major part of fertilizer become available for excessive algal growth. The water in a pond must remain clean if it is to provide a healthy environment for the organisms (animals and plants) living in it. Suitable for: K – 5. These algae form a layer on top of the pond or lake. Thus tannin – lignin (0.9 ppm), NH3 (0.5-6 ppm), phenol (0.002 ppm) are found in barrage water, exceeding their respective tolerance limits. Guppies, Cycles, and Ecosystems Science Project from StudyWeb, Pond Life and Pond Food Chain Science Project from Science Teaching Center, Exploring Pond Life with Kids from Kids Activities Blog, Algae and Pollution Science Experiment  from Layers of Learning, Learn About the Carbon Cycle with Bottle Ecosystems  from The Geo Exchange, Build a Mini Ecosystem for Nature Observation from Stir the Wonder, Inspecting Pond Water with Preschoolers from Stir the Wonder. Addition of nutrients, stimulate luxuriant growth of algae in these waters. Cadmium poisoning is, called itai-itai (“ouch-ouch”) in Japan because it is a painful disease that can be fatal. This is a threat to human health as they cause a num­ber of water-borne diseases such as typhoid, dysentery, hepatitis etc. In general, deep lakes and marine environments are likely to undergo seasonal thermal stratification into a warm surface layer (epilimnion), an underlying layer of cool water of higher density (hypolimnion). Any pollution of soil of one field need not always affect the soil of neighbouring field. Water pollution can cause an entire ecosystem to collapse if left unchecked. Oil spillages from tankers act as a toxic substance and affects the aquatic organisms. These are some of the problems which can only be solved through careful preservation techniques. On the contrary some of them are useful in improving the quality of water. There are many types and sources of water pollution. Coal mines, especially those which have been abandoned, discharge substantial quantities of H2SO4 and also Fe (OH)3, into local streams through sewage. Some of them like DDT, DDE, DDD, Dielrin and polychorinated biphenyls are washed down with rain water and find their way to the sea through rivers and streams. Considerable pollution is caused by such industries as leather tanneries, beet sugar refining and meat packing. 3. Classification 7. Humans use fresh water in many ways, but these activities can be dangerous for freshwater ecosystems when we are not careful. A project report on water pollution. To protect the river from harmful pollutants, the Minnesota Pollution Control Can I admit that I literally had to stop myself from listing every single holiday STEM activity beca, How to Teach Science to the Child Who Hates Science, What I remember from science is textbooks and labs that I never understood. Games, experiments and activities. Pond ecosystem is a freshwater ecosystem with the complex interaction between its biotic and abiotic components. Project Report # 3. Water tastes bitter when contaminated with alkaline impurities and salty when the impurities are metallic salts. Project Report # 2. 12. It has increased to 20,000 persons per sq. Pond Life and Pond Food Chain Science Project from Science Teaching Center. Principal components analysis ordination of elemental concentrations in surface water at the saline habitat ponds and reference sites, Ecosystem Monitoring Project, Salton Sea, California, One such toxin, strychnine, secreted by decomposing plants kills animals including cattle. Hardness may be temporary or permanent. Proper water quality is crucial to the protection of the natural habitats of fish, bugs, bird, and plant communities. “We’re excited to be starting this project. Water pollution can be defined as the presence in water, of some foreign Substances or impurities (organic, inorganic, radiological or biological in such quantity so as to constitute a health hazard by lowering the water quality and making it unfit for use. (e) In area of acute water scarcity, waste water treated to the highest standards can be reused as potable water (provided there is public acceptance for waste water use). Biological oxygen demand is the amount of oxygen required by bacteria in a pond in a unit volume of water at a specified time. 4. 2. Growth of algae, micro-organisms, hydrogen sulphide and ammonia give an obnoxious odour to water making if unfit for use. Those sources whose location cannot be easily identified are called diffused sources. phenyl mercury acetate, C6H5HgOCOCH3 — toxic to moulds (fungi) and check plant disease. In the early period of human civilization it was realised that pests harm crops and transmit diseases both to men and animals. Nitrate in agricultural drainage contaminate drinking water. This may interrupt or prevent the reproduction of fish by smothering eggs laid on the bottom. The unpleasant taste and odour is aesthetically unacceptable even though it may not pose any serious threat to health. Mercury poisoning produce a crippling and often fatal disease called Minamata disease (mercury poisoning occurred in Minamata City, Japan in 1953, when more than 100 persons died or suffered serious nervous system damage from, eating fish taken from Minamata Bay). A pond ecosystem can be defined in three ways. Fe3+ dissolves pyrite fur­ther and together with the second reaction above, constitute a cycle for the dissolution of pyrite. Remember to have jars of clean water, air, and snow so students can compare the clean ones with the polluted ones. 10-50); Varanasi is the second polluted zone (D.O. imparts objectionable and offensive tastes, odours and colours to fish and aquatic plants even when they are present in low concentrations. For example, a pond used to supply drinking water for animals should be tested for different parameters than a pond used exclusively for fishing. Heavy metal ions, if present, will be precipitated as metal sulphides which settle at the sediment layer at the bottom. The is very little water flow in a pond. and their addition into water bodies makes it rich in nutrients, especially phosphate and nitrate ions. Such composite samples are useful for determining the average condition which, when correlated with flow, can be used for computing the material balance of a stream of water body over a period of time. The report also showed that poor lake conditions related to nitrogen or phosphorus pollution doubled the likelihood of poor ecosystem health. 2. Hydrosphere includes sea, rivers, oceans, lakes, ponds, streams etc. Oil from spills and washing of automobiles sometimes pollutes our water. Any substance that adversely affects the productivity of the soil is a soil pollutant Soil pollution is also called as land pollution. Create Your Own Ecosystems or Habitats. Major Sources 5. Besides direct consumption (washing, bathing, drinking) man uses water for a multi­tude of purposes like irrigation, industry, navigation, recreation, construction work, power generation and waste disposal. Project Report # 13. Project Report, Environment, Pollutions, Water Pollution, Project Report on Water Pollution, Terms of Service Privacy Policy Contact Us. Environment of Aquatic in Water: Water quality characteristic of aquatic environment arises from a multitude of physical, chemical and biological interaction. (d) Treated water can be reused for cooling processes in thermal plants. The conventional water treatment methods fail to remove organic matter, phenol and toxic metals so that these find their way into domestic water supply. km., compared to 200 for the whole of India. Caustic soda and chlorine factories release heavy metals such as cadmium, chromium, copper, lead, nickel, zinc and mercury. 3. present in the organic debris water is aesthetically unacceptable and unsuitable for bathing, laundering, beverage manufacturing, food pro­cessing etc. From the Great Lakes, the Great Salt Lake, Walden Pond, Loch Ness, and the pond down the street from school, readers discover the life teeming in and around lakes and ponds. It can be something as simple as collecting pond water, organisms, and plants. Overfishing, pollution, and disruption of the landscape through projects like dams and deforestation are just a few ways we can put these ecosystems—and ultimately, our own access to fresh water—at risk. value is an index of pollution mainly due to organic matter, e.g. The water pollution caused by point sources can be minimised if all domestic sewage, industrial effluents, cattle field and livestock wastewater etc. The Hooghly river near Calcutta is contaminated with waste effluents from about 150 industries (including 87 jute mills, 12 textile mills, 7 tanneies, 5 paper mills and 4 distilleries) as well as domestic sewage from 360 out falls on both sides of the river. The population showed higher levels of heavy metals and pesticides in their hair (cd 3-5 ppm, Cr 2 ppm, Pb 50 ppm) respectively. unclean or unsafe it is called pollution. For analysis of natural and waste water, two principal types of sampling procedures are employed: 1. Signs 4. 5. Carbonate rocks have been suggested for remedial measures: But with rise in pH as this reaction proceeds, Fe (OH)3 present in the system covers the particles of carbonate rock with a relatively impermeable layer. Polyphosphate in detergents, the major sources of phosphate in water, serve as algal nutrients and are of much concern as water pollutants. About 0.1% of the total insects (500 species out of world total of 5.0 million) are harmful-these are mostly agricultural pests which are also carriers of human or animal diseases. Oil pollution of the seas has increased over the years due to the increased use of oil- based technology. Problems 10. Remember that the organisms living in an ecosystem are broken down into categories: producers, consumers, and decomposers. The oceanic zone is the vast open part of the ocean where animals such as whales, sharks, and tuna live. Pollution of Ponds. Phytoplankton biomass initially increa­ses. Swages must be treated before it is dis­charged into the water. The release of raw sewage into lakes, rivers, ponds etc. In a pond ecosystem, the primary consumers are tadpole larvae of frogs, fishes and other aquatic animals which consume green plants and algae as their food. Science Experiments & Projects ... this leads to water pollution. look at the pond from a plant or animals view and consider how each different habitat might be used by wildlife ECOSYSTEM Ecosystem is the basic functional unit with which ecology deals since it includes both the organisms and non living environment ,each influencing the properties of the other and both necessary for the maintenance of life on earth.
