Pollution can take the form of chemical substances or energy, such as noise, heat or light. Pollutants, the components of pollution, can be either foreign substances\/energies or naturally occurring contaminants. Pollution is often classed as point source or nonpoint source pollution. Air pollution, water pollution, soil contamination, noise pollution and light pollution are some of the different types of environmental pollution.<\/p>\n<p>Eutrophication is the process by which a body of water becomes enriched in nutrients, particularly phosphorus and nitrogen. This process can lead to the growth of excessive amounts of algae and other aquatic plants, a condition <div class=\"telegram-channel-container\">\r\n        <a href=\"https:\/\/t.me\/pscnotes2025\" target=\"_blank\" class=\"telegram-channel-button\">\r\n            <span class=\"telegram-icon\">\r\n                <svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" viewBox=\"0 0 496 512\">\r\n                    <path fill=\"white\" d=\"M248,8C111,8,0,119,0,256s111,248,248,248s248-111,248-248S385,8,248,8z M362,177L320,367c-3,14-10,18-20,14l-56-41l-27,26 c-3,3-5,5-10,5l4-63L323,196c5-5-1-7-8-3l-98,62l-42-13c-9-3-10-9,2-14l162-63C351,160,365,164,362,177z\"\/>\r\n                <\/svg>\r\n            <\/span>\r\n            Join Our Telegram Channel\r\n        <\/a>\r\n    <\/div> known as an algal bloom.

This occurs because the substance is not broken down or excreted by the organism, and so it builds up in the tissues.
