Some coastal waters arecontainminated by oil, zinc, solid waster and seafloor sediment quality, the habitat of marine species are also polluted seriously. The phenomenon of red tide appeared in our country, especially in Khanh Hoa, Ninh Thuan, Binh Thuan. It caused huge damage, for example, the appearance of the type of harmful algae, the death of sea animals such as shrimp, fish or crab. Các bãi biển đẹp, nổi tiếng về du lịch như Phú Quốc, vịnh Hạ Long… đang bị nhiễm đục và rác thải tấn công, thậm chí nhiều nơi du khách than phiền nước biển gây ngứa. Beautiful and famous beaches as Phu Quoc, Ha Long Bay,… are effected by garbage, even tourists complained that sea water causes itch.
As industries dump industrial waste into our rivers, creeks, lakes, oceans and other bodies of water it causes an imbalance in the water leading to the severe death and contamination of aquatic species. In fact, the main problem caused by water pollution is that it kills organisms that depend on these water bodies. Irreparable damage to the water bodies are caused by oil spills in the ocean and spraying of insecticides and pesticides like DDT on our plants, as well as industrial waste and illegal
Atmospheric pollution is caused by pollutants such as smoke from factories entering the atmosphere and being carried to waterways. Industrial waste can also create polluted runoff that collects in rivers and lakes. Another reason for water pollution is chemically treated sewage. This water carries harmful chemicals and high amounts of bacteria, which can potentially lead to serious diseases. Runoff from fields can contain chemical fertilizers and pesticides which can pollute
Unlike most other countries that experience pollution from a fewer number of sources, Kuwait has been plagued air, land, noise, thermal, oil, waste water and marine pollution. Although these types vary in terms of their intensity and prevalence, still they present a major threat to the environment of the region. It should be remembered that Kuwait had made the headlines during the Iran Iraq war when the Iraqi army had set fire to most of the oil fields in the region. This act had resulted in alarming levels of air pollution in the region. In the present times, the pollution in the region is being primarily caused by oil refineries, manufacturing units and industrial plants.
The rainwater that washes away the chemicals, sediments, motor oil, antifreeze pollutants, and fertilizers ends up in the nearest beaches and causes a huge environmental risk. At the combined sewer plants, untreated domestic and industrial waste water overflows during a rainy season and ends up into the streams and beaches. Similarly, sanitary systems are affected by blockades, line breaks, sewer defects and leaks, inadequate design and vandalism, and lapses in maintenance to force the polluted water to make its way to the streams and beaches. The combined grease, chemicals, nutrients, mixture of raw sewage, industrial wastewater, harmful metals, and bacteria have resulted in the closing of several beaches, shellfish bed closing, and aesthetic and environmental problems (“Sources of Beach Pollution”). Moreover, the discharges from recreational and commercial vessels such as trash, fishing gear, ballast water, domestic waste, paints, and other chemicals are also a source of pollution for the beaches as an increased number of such vessels contributes towards the accumulation of waste and pollution from them.
Thermal pollution is the changing or altering the temperature of a natural body of water by either adding water that has been cooled or heated. The water body may be a river, lake stream, pond or oceanic environment. It may also be defined as the heating or cooling of water from a natural source by industrial or anthropogenic activities which is ejected back to the source. This can cause lowering or depletion of oxygen level and is dangerous to the environment especially marine environments. Thermal pollution is caused by numerous activities including runoff from paved surfaces, water used as cooling agents in factories, soil erosion deforestation.
1. Introduction Over decade’s water pollution incidents are the most detrimental effects of biosphere, which may cause greenhouse effect, acid rain and unsuitable contamination of drinking water or water quality (P. K. Goel, 2006). Water pollution is the direct or indirect alteration of chemical, physical and biological factors that affect water quality (P. K. Goel, 2006). It is the contamination of water courses such as rivers, ground water, aquifer, lakes, oceans, water pipes and boreholes. Water pollution has been a major problem all over the world which can cause certain diseases and affect the ecological section (F.W Owa, 2014).
Pollution is one of the most serious issues the world confronts today. It means adding contamination to environment. The nature 's domain consists of earth, water, air, plants and creatures. If we contaminate them, then the presence of man and nature will be hampered, and our naturally beautiful world becomes ugly because it is suffering from the effects of environmental pollution. There are many types of pollution, namely water, air and noise.
The pollutants that discharge directly or indirectly into water bodies without sufficient treatment to remove harmful mixtures are called water pollution ("Environmental pollution," n.d.). The lives of animals are disturbed by human activities that contaminate the soil. Environmental contamination kills the fish and insects, which leads them to extinction. To explain, Pesticides are a source of pollution, agriculturalists use pesticides to prevent insects from eating crops. Pesticides stay in harvests, wild plants eaten by herbivores, and insects.
There are many examples of environmental pollution in recent years. According to estimates of the Hydrometeorological, every year on the East Coast up to 9 to 10 hurricanes and 3 to 4 activities storms directly affect Vietnam, the phenomenon of desertification in the central coast are place more quickly have a large effect on the lives and production of residents. The most serious is that the area of the Mekong Delta in our country will be able submerged below sea level in the near future, a region of fertile deltas, a bowl of water lualon we can take go if now we do not take timely measures to correct. And also how the immeasurable impact that climate change poses to the people of
