Nitrogen often is the limiting nutrient for the growth of algae and phytoplankton in estuaries and surface waters in California. To control cultural eutrophication (i.e., excessive growth of algae and plankton related to anthropogenic sources) regulatory agencies often focus on the control of point source discharges, including municipal wastewater effluent. Recent attempts to control cultural e...

Abstract. The phase behaviour of aerosol particles plays a profound role in atmospheric physicochemical processes, influencing their physical and optical properties further impacting climate air quality. However, understanding the state is still incomplete, especially that multicomponent which contain inorganic compounds secondary organic (SOA) from mixed volatile compound (VOC) precursors. We ...

During disinfection of drinking water, natural organic matter reacts with chlorine to produce harmful by-products. The identification precursors by-products in is challenging because very complex and poorly known. Therefore, scientists have focused on the fractionation membranes or resins better understand how which fractions react during chlorination. Here, we compared reactivity various For t...

Organic compounds and liquid water are major aerosol constituents in the southeast United States (SE US). Water associated with inorganic constituents (inorganic water) can contribute to the partitioning medium for organic aerosol when relative humidities or organic matter to organic carbon (OM /OC) ratios are high such that separation relative humidities (SRH) are below the ambient relative hu...
