Organic Pollutants: sources, pathways, and fate through urban wastewater treatment systems 3.1 Sources and pathways of organic pollutants in UWW There are a large number of organic pollutants from a wide range of sources which may enter UWW. MACROSCOPIC. These compounds are non-biodegradable and persist in the environment. Primary pollutants largely differ from secondary pollutants such that they do not form in the atmosphere unlike secondary pollutants. Pollutants Organic pollutants and nutrients. Figure 4 (a-e). There are many different chemicals in the form of pollutants, and they range from simple ions to complex molecules. Due to natural and anthropogenic sources, water becomes polluted that results in the origin of different water pollutants. Pathogens/Infectious agents (Examples) ... Organic chemicals (Examples) Oil, gas, plastics, pesticides, cleaning solvents. Because they can be transported by wind and water, most POPs generated in one country can and do affect people and wildlife far … POPs have low solubility in water but are easily captured by solid particles, and are soluble in organic fluids (oils, fats, and liquid fuels). Volatile organic compounds, or VOCs, are substances that contain carbon and evaporate (becomes a vapor) or “off-gases” at room temperature. Examples of organic and inorganic waste Gases like H2S, NH3, Co2 etc dissolved in water during raining. They are freshwater pollutants that generally enter into surface water via sewage works. For instance, the industrial waste consists of toxic contaminants which hamper the quality of water.
