1. Surface reactivity, stability, and mobility of metal nanoparticles in aqueous solutions : Influence of natural organic matter and implications on particle dispersion preparation
Abstract : The growing development of nanotechnology has resulted in an increased use of nanoparticles (NPs) in various applications ranging from medicine, military, to daily consumer products. There is a concern that NPs can be dispersed into the environment in various ways, for example to air and water during manufacture, use, incineration or recycling of products and thus pose a risk to health and the environment.

4. Baltic Sea sediments : Source and sink for metal contamination
Abstract : The Baltic Sea sediments record spatial and temporal information about metalsand metalloids (hereafter referred to as metals), which could help to understandthe past and present contamination sinks in different basins. In addition, giventhe expanding anoxic zones in the Baltic Sea, the response of metals to artificialreoxygenation is poorly understood. READ MORE

5. Physico-chemical properties of some aquatic fulvic acids - functional groups and stability
Abstract : Humic material constitutes a category of naturally produced organicmacrocompounds, widely spread in both terrestrial and aquatic systems and accounting for up to 70% of the total soil carbon and 50% of the dissolved organic carbon in surface waters. Humic material is formed as the result of complex chemical transformations of biomass. READ MORE
