Organic pollutants

The organic pollutants taken up by plants are used for feeding fowl and livestock, and thus consequently increase the possible exposure to pollutants of humans and other living beings (Yu et al., 2011; Zhu et al., 2014). The degradation and accumulation of the organic pollutants by plants depend on the physicochemical properties (Gao and Zhu, 2003). However, some organic compounds such as xenobiotics cannot be degraded easily; they are known as persistent organic pollutants The Stockholm Convention on Persistent Organic Pollutants adopted in 2001 deals with persistent organic pollutants (POPs), i.e. substances that possess toxic properties and resist degradation. They include pesticides such as DDT and lindane, industrial chemicals such as polychlorinated biphenyls (PCBs), and substances such as dioxins, which are the unwanted by-products of manufacturing and combustion processes

Organic Pollution. Organic pollution and compounds associated with organic matter such as pharmaceuticals and cosmetics seem to be best monitored in sediments where both natural organic compounds and anthropogenic organic pollutants accumulate, making sediments an accumulation hotspot (Jacquiod et al., 2018). From: Water Research, 2021. Related terms The organic pollution removal from inorganic cultural heritage objects is based on their oxidation in oxygen-based plasmas. The thickness of the surface layer depends on the material of which the object is made and on the technological history of the object (Belkind and Gershman, 2008)

Organic Pollutants - Monitoring, Risk and Treatment

Organic Pollution is biodegradable contaminants in an environment. These sources of pollution are naturally found and caused by the environment (such as oil which is found throughout most of the world)(2) Organic Pollution. Organic pollution is a type of chemical pollution caused by carbon pollutants, such as organic matter (liquid manure, sewage treatment sludge, etc.), organochlorides ( DDT) or even polychlorinated biphenyls ( PCB ). In the case of organic matter, pollutants can increase water turbidity and cause eutrophication with a decrease in. Organic pollutants consist of proteins, carbohydrates, fats and nucleic acids in a multiplicity of combinations. Raw sewage is 99,9 per cent water, and of the 0,1 per cent solids, 70 per cent is organic (65 per cent proteins, 25 per cent carbohydrates, 10 per cent fats) Apart from the organic matter discharged in the water body through sewage and industrial wastes, high concentration of heavy metals and other inorganic pollutants contaminate the water. These compounds are non-biodegradable and persist in the environment. These pollutants include mineral acids, inorganic salts, trace elements, metals, metals compounds, complexes of metals with organic compounds, cyanides, sulphates, etc

Persistent organic pollutants (POPs) are toxic chemicals that adversely affect human health and the environment around the world. Because they can be transported by wind and water, most POPs generated in one country can and do affect people and wildlife far from where they are used and released Persistent organic pollutants, sometimes known as forever chemicals are organic compounds that are resistant to environmental degradation through chemical, biological, and photolytic processes. Because of their persistence, POPs bioaccumulate with potential adverse impacts on human health and the environment. The effect of POPs on human and environmental health was discussed, with intention to eliminate or severely restrict their production, by the international community at the Stockholm Con Organic pollutant refers to. Pollutants that contain carbon elements in their composition. If we look at the harmful effects of organic pollutants, they are very dangerous الملوثات العضوية الثابتة (بالإنجليزية: Persistent organic pollutants POPs)‏ هي نوع من المركبات العضوية المقاومة للتدهور أو الإنحلال البيئي من خلال العمليات الكيميائية والبيولوجية والتحلل الضوئي The level of organic pollution in a river, commonly expressed by the Biochemical Oxygen Demand (BOD) 4, is the result of two counteracting mechanisms: pollutant loading and natural cleaning (Fig...

Electro-Fenton process is also being combined with biological methods to mineralize organic pollutants in water (Annabi et al. 2016; Ganzenko et al. 2017). The coupling of electro-Fenton with biological degradation is a new and interesting tool. The coupled process is called bioelectro-Fenton process (Olvera-Vargas et al. 2016a, b) Persistent organic pollutants (POPs) are organic compounds that, to a varying degree, resist photolytic, biological and chemical degradation. They are characterized by low water solubility and high water solubility, leading to their bioaccumulation in fatty tissues. They are also semi-volatile

Persistent organic pollutants (POPs) are chemicals of global concern due to their potential for long-range transport, persistence in the environment, ability to bio-magnify and bio-accumulate in ecosystems, as well as their significant negative effects on human health and the environment. The most commonly encountered POPs are organochlorine. This Organic Pollutants section of Frontiers in Environmental Chemistry focuses on understanding the transport of organic pollutants across all compartments, their environmental partitioning behavior, biotic and abiotic transformation and the chemistry influencing their interaction with biological tissues The CoS 2−x /Fe 2+ system can degrade organic pollutants efficiently for up to 30 days, which is significantly better than the currently recognized CuP x system (<3 days). Therefore, CoS 2−x provides a new choice for the long-term remediation of organic pollutants in controlling large area river pollution The Stockholm Convention on Persistent Organic Pollutants is a multilateral treaty to protect human health and the environment from chemicals, known as POPs. POPs have harmful impacts on human health or on the environment. They remain intact in the environment for long periods, become widely distributed geographically and accumulate in the fatty tissue of humans and wildlife Organic pollutants include pesticides, fertilizers, hydrocarbons, phenols, plasticizers, biphenyls, de‐ tergents, oils, greases, pharmaceuticals, proteins and carbohydrates [1-3]. Toxic organic pollutants cause several environmental problems to our environment. The most common organic pollutants named persistent organic pollutants (POPs.

Persistent organic pollutants are organic. This means that they consist of, or are derived from, living matter. It is a misconception that all organic matter is biodegradable. Conclusion: POPs are highly dangerous for the environment, particularly because they do not degrade, and therefore their use in agriculture and industry should be reduced Know more about Persistent Organic Pollutants (POPs) such as PBDEs and PCBs, and why we need to act against them
