Several recent studies have shown that n-octanol/water partition coefficients may not be a good predictor for estimating soil sorption coefficients of persistent organic pollutants (POPs), defined here as chemicals with log Kow greater than 5. Thus, an alternative QSAR model was developed that seems to provide reliable estimates for the soil sorption coefficients of persistent organic pollutant...

An Era of Hazard: Persistent Organic Pollutants By Marco A. Olsen, S.J.D. Candidate In May 2001, representatives from over 122 countries, NGOs representing citizens and the chemical industry, met in Stockholm to adopt and open for signature The Stockholm Convention on Persistent Organic Pollutants. The Convention is a legally binding treaty designed to protect human health and the environment f...

The synthesis of existing Persistent Organic Pollutants pollution monitoring databases with epidemiological data is considered for identifying some impacts of Persistent Organic Pollutants on human health. This task requires new rich data, services, and model discovery capabilities from a multitude of monitoring networks and web resources. The FP7 project TaToo (Tagging Tool based on a Semantic...

Over the years, chemical market has shown significant growth, but hazardous impact of use and disposal on environment human health is a growing concern. Persistent organic pollutants (POPs) are among most dangerous chemicals with widespread effects living organisms, including humans. This study aimed to assess current status POP management regulatory infrastructure in Ethiopia by collecting inf...

Shocked that chemical offshoots of his company's products were winding up in polar bears and seals, the CEO of 3M put an end to the existing version of Scotchgard® in 2000. Business observers were struck by how quickly this multinational corporation removed a flagship commodity worth hundreds of millions of dollars from the market. Now some scientific observers are becoming impressed by how qui...
