- 15 April 2006
Polycyclic aromatic hydrocarbons (PAHs) and heavy metals were measured in road debris collecting in urban areas and in the suspended sediment (SS) component of runoff from two stormwater catchments… Expand
Disposal practices for unused medications around the world.
Pharmaceuticals have been detected throughout the environment where at least in some cases, they have been shown to have a detrimental effect. Many result from improper patient disposal of unused… Expand
Dissolved organic carbon and organic acids in coastal New Zealand rainwater
Abstract Dissolved organic carbon (DOC), formate, acetate, oxalate and a variety of inorganic ions were measured in 54 rain events collected on the southern portion of the South Island of New… Expand

Sunlight-induced molecular changes have been observed in two samples of dissolved organic matter (DOM) collected in the Cape Fear River system, North Carolina, USA. The molecular composition of a… Expand
Free Radical Destruction of β-Blockers in Aqueous Solution
Many pharmaceutical compounds and metabolites are currently found in surface and ground waters which indicates their ineffective removal by conventional water treatment technologies. Advanced… Expand
Determination of colloidally-associated polycyclic aromatic hydrocarbons (PAHs) in fresh water using C18 solid phase extraction disks
Abstract A new application of reversed-phase octadecyl (C18) solid phase extraction disks has been developed to separate the colloidally-associated polycyclic aromatic hydrocarbons (PAHs) from those… Expand
Production and decomposition dynamics of hydrogen peroxide in freshwater
Environmental context. Hydrogen peroxide (H2O2) is the most stable reactive oxygen species (ROS) formed through irradiation of chromophoric dissolved organic matter (CDOM) in freshwater. It can act… Expand
Disposal practices for unused medications in New Zealand.
BACKGROUND There is an enhanced international awareness that the improper disposal of unwanted and unused medications may have a detrimental effect on the environment. OBJECTIVES The aim of this… Expand
