Are organic compounds that include synthesized substances.
Air Pollutants: Persistent Organic Pollutants (POPs). Persistent organic pollutants are compounds which are resistant to degradation and persistent in the environment, with half lives of years in the soil or sediment and days in the atmosphere. Nitrogen dioxide (NO2) is both a primary and secondary air pollutant. Other important gaseous pollutants are: ammonia, carbon monoxide, volatile organic compounds (VOCs) and persistent organic pollutants (POPs) which we discuss below. DRAFT Persistent Organic Pollutants and the Stockholm Convention Page 5 Hawaii. Mirex is also used as a fire retardant in plastics, rubber, paint, paper and electrical goods. Mirex is one of the most stable and persistent POPs. Persistent Organic Pollutants and the Stockholm Convention Page 1 1. Introduction The World Bank is an implementing agency with the United Nations Environment Program and United Nations Development Program of the Global Environment Facility (GEF). International treaties such as the Stockholm Convention on Persistent Organic pollutants have attempted to regulate and restrict the use of pesticides and other chemicals which are highly persistent in the environment (e.g., DDT) since such persistence may lead to biological consequences for wildlife and human health. K. Racke, N. Simmons, C. Tiu Dow AgroSciences 9330 Zionsville Road Indianapolis, Indiana USA 46268 Introduction At times, pesticide opponents may raise questions about chlorpyrifos and other modern insecticide products concerning their potential classification as “persistent organic pollutants” or “POPs”. It was prepared for use by decision-makers and a general audience. 2. Persistent Organic Pollutants (POPs) 2.1 General characteristics of persistent organic pollutants Persistent organic pollutants are organic (carbon-based) compounds that include synthesized substances (pesticides and PCBs). Persistent Organic Pollutants and the Stockholm Convention Page 1 1. Introduction The World Bank is an implementing agency with the United Nations Environment Program and United Nations Development Program of the Global Environment Facility (GEF). Introduction. Some organic pesticides are the most widespread POPs (Persistent Organic Pollutants) used in agriculture worldwide. Other POPs such as volatilized industrial pollutants as well as pollutants from fuel combustion can also contaminate large areas due to dispersion by wind and rainfall. The fate of pollutants in the soil depends on the soil properties and the physical chemical characteristics of these molecules. Essentially the uptake of pollutants in the soil can be understood to be the result of chemical attraction and bond strength. The name POPs refers to many pollutants such as pesticides like DDT and pollutants like PCBs. These chemicals come from pesticides, industrial chemicals, and are the unwanted by-products of industrial processes or combustion. ‘DDT’ stands for Dichlorodiphenyltrichloroethane.  DRAFT Persistent Organic Pollutants and the Stockholm Convention Page 3 neurobehavioral and developmental disorders, endocrine disruption and cancer. Many persistent organic pollutants are considered possible human carcinogens by the International Agency for Research on Cancer (IARC) of the World Health Organization. Persistent Organic Pollutants and the Stockholm Convention Page 1 1. Introduction The World Bank is an implementing agency with the United Nations Environment Program and United Nations Development Program of the Global Environment Facility (GEF). 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 Convention on Persistent Organic Pollutants in 2001. 1 Dioxins are unintentional by-products of high-temperature processes, such as incomplete combustion and pesticide production. 2  Dioxins are typically emitted from the burning of hospital waste, municipal waste, and hazardous waste, along with automobile emissions, peat, coal, and wood. Persistent organic pollutants (POP s) are organic compounds that are resistant to environmental degradation through chemical, biological, and photolytic processes. 1 Dioxins are unintentional by-products of high-temperature processes, such as incomplete combustion and pesticide production. 2  Dioxins are typically emitted from the burning of hospital waste, municipal waste, and hazardous waste, along with automobile emissions, peat, coal, and wood.
