A dynamic porous coordination network with a hydrophobic channel was assembled from stretchable 1D metallosalen polymer, which has the ability to recognize and, particularly, separate aromatic hydrocarbons from aliphatic mixtures with high selectivity.

The paper is a contribution for the knowledge upon concentrations and fate of different kinds of organic micropollutants in Tropical River system from a very industrialized region in Brazil. The presented data was obtained during three years of an International Research Project between Brazilian and Dutch institutions. The sediments were sampled at the Paraiba do Sul-Guandu river watershed, the...

To assess the organochlorine contamination in the northeast coastal environment of Vietnam, a total of 41 surface sediments were collected from Ha Long Bay, Hai Phong Bay, and Ba Lat estuary, and analyzed for their organochlorine content. Organochlorine compounds (OCs) were widely distributed in the Vietnamese coastal environment. Among the OCs measured, DDT compounds predominated with concentr...

On Zugspitze (2670 m a.s.l.), Alps, higher concentrations were observed during a winter than during a summer measurement campaign of PAHs, chlorobenzenes (43.6 vs. 2.0 pg m(-3)) and DDTs (3.7 vs. 1.2 pg m(-3)), while hexachlorocyclohexanes and PCBs were found at similar levels. The PCB, HCH and DDT levels are among the lowest ever reported from outside the Arctic. Mostly lower levels were found...

A little over a decade ago, Waldichuk (1990) reviewed the state of industrial and domestic pollution of the North Pacific and concluded that interfaces (e.g., air-water, water-sediment, shorelines) and coastal areas, especially those surrounded by dense population and industry, were most at risk. His list of critical contaminants – hydrocarbons and polynuclear aromatic hydrocarbons (PAHs), orga...

1.1 This gas chromatographic method is designed to determine the concentrations in soil and water of petroleum hydrocarbons from nhexane (C6) to n-pentatriacontane (C 35); an approximate boiling point range from 70C to 500C. This includes the gasoline, diesel range, and some portions of heavier fuels and lubricating oils. This method also describes the separation of the petroleum hydrocarbons i...
