The inorganic water pollution is associated with the entering of mineral substances, chemical compounds, and toxic waste. Nutrient pollution is the process where too many nutrients, mainly nitrogen and phosphorus, are added to bodies of water and can act like fertilizer, causing excessive growth of algae. Water pollution is a major global problem which requires ongoing evaluation and revision of water resource policy at all levels (international down to individual aquifers and wells). The Bor River is actually considered to be one of the most polluted water streams in Europe [].Despite containing high levels of heavy metals and having a low pH, this river accommodates bacterial life [].However, no field survey has investigated the effects of extensive inorganic pollution on enzymatic activity of sediment bacterial communities. 2. Water pollution refers to the presence of compounds that decrease the quality of fresh or marine water. The U.S. Food and Drug Administration proposed in 2013 to limit the amount of inorganic arsenic in apple juice to 10 parts per billion, the same level set for water. Scientists link nutrient pollution to coral bleaching. A point-source pollutant is one that reaches water from a single pipeline or channel, such as a sewage discharge or outfall pipe. ♦ Disposing of waste in the water bodies. Water pollution (or aquatic pollution) is the contamination of water bodies, usually as a result of human activities.Water bodies include for example lakes, rivers, oceans, aquifers and groundwater.Water pollution results when contaminants are introduced into the natural environment. Many inorganic materials take a long time to biodegrade, which means that their buildup rate is almost proportional to the total rate of pollution at any given time. This is a broad definition that takes into account a variety of water sources including lakes, streams, rivers, oceans, and groundwater. 2 Reviews. In such a case, marine life cannot survive.
