To develop urban stormwater management effectively, characterization of urban runoff pollution between dissolved and particulate phases was studied by 12 rainfall events monitored for five typical urban catchments. The average event mean concentration (AEMC) of runoff pollutants in different phases was evaluated. The AEMC values of runoff pollutants in different phases from urban roads were higher than the ones from urban roofs. The proportions of total dissolved solids, total dissolved nitrogen, and total dissolved phosphorus in total ones for all the catchments were 26.19%–30.91%, 83.29%–90.

Microcystin can be present in variable concentrations, phases (dissolved and particulate), and structural forms (congeners), all which impact the toxicity and persistence of the algal metabolite. Conducting incubation experiments with six bloom assemblages collected from the Chowan River, North Carolina, we assessed microcystin dynamics during active growth and biomass degradation. Upon collection, average particulate and dissolved microcystin ranged between 0.2 and 993 µg L−1 and 0.5 and 3.6 µg L−1, respectively.

Dissolved and particulate metal concentrations in the St. Lawrence estuary were determined during the high spring runoff and at a period of lower runoff in the fall. The distributions in the estuary are influenced by seasonally variable freshwater discharges and a turbidity maximum zone (TMZ). Dissolved Al, Fe, Mn, Co, Cu, Ni, and Zn concentrations generally decrease significantly with increasing salinity, but Cd shows no significant covarience with salinity. Most metals show complex distribution patterns, and only the distributions of Cu and Ni can be described by linear regression equations.

Measurements of trace metals in the dissolved, suspended particulate and sediment phases of the Tamar Estuary have been combined with observations of sediment and suspended particle mobility in an interpretation of metal cycling and retention processes within the system. Dissolved metal distributions indicate pronounced estuarine metal reactivity involving net removal onto suspended particles in the low salinity, high turbidity zone and net input from the sediment in the middle estuary.

The supply and bioavailability of dissolved iron sets the magnitude of surface productivity for ∼40% of the global ocean. The redox state, organic complexation, and phase (dissolved versus particulate) of iron are key determinants of iron bioavailability in the marine realm, although the mechanisms facilitating exchange between iron species (inorganic and organic) and phases are poorly constrained.

Mn is a geochemically important element that contributes significantly to the cycling of heavy metals.

Therefore, this study was undertaken to provide a quantitative understanding of the coprecipitation of Pb with Mn oxyhydroxides to demonstrate their capacity to remove Pb permanently from contaminated solutions.

Abstract The operating mileage of North American pipelines transporting lowdensity, high APIgravity hydrocarbon liquids has increased significantly over the past two decades. This trend began in the early 2000’s because of increasing oil sands production in Canada, where light hydrocarbons are used to reduce the viscosity of bitumen to achieve practical ‘heavy oil’ specifications suitable for pipeline transport. The light tight oil boom of the 2010’s continued this trend, as multistage fracking unlocked high API gravity liquids from previously low permeability shale and sandstone formations. W

Abstract Over the past 15 years, increasing production of bitumen from oil sands operations has led to increased need for long distance transport of very light liquid hydrocarbons used as diluents. Over the same time frame, multistage fracking has led to dramatic increases in production of very light shale oils ("tight oil") having comparable physical properties to hydrocarbons used as diluents. These products typically contain very little water or dissolved gases - and hence are markedly similar to finished products such as motor fuels.

Abstract The pitting corrosion resistance of three types of lean duplex stainless steels (grades UNS S32003, UNS S32101 & UNS S32304) along with duplex stainless steel grades (UNS S31803 & UNS S32550) and super duplex stainless steel (grades UNS S32750 & UNS S32760) were investigated using the potentiodynamic polarisation technique. Results are discussed based on data generated in an autoclave for wide range of chloride concentrations (15-22,000 ppm) and temperatures (60°C-170°C) in 8ppm dissolved oxygen. Super duplex stainless steel (SDSS) showed superior pitting resistance in all

Abstract The electrochemical and microstructural response of metal matrix composites (MMCs) under different erosion-corrosion conditions is assessed in this paper. The MMCs are plasma transferred arc (PTA) overlays, produced by reinforcing two iron base and two nickel base hardfacing matrices with tungsten carbide (WC) particles. The microstructures are examined using scanning electron microscopy (SEM) and stereology techniques. The electrochemical response under erosion-corrosion conditions, assessed by in-situ potentiodynamic techniques, is analyzed as a function of sand content (10 and 50 g

Abstract Sour well design is often limited by susceptibility to H2S-related cracking mechanisms. Recent experimental evidence has demonstrated that in high pressure systems, parameters such as dissolved H2S concentration or H2S activity or related fugacity govern the tendency of carbon steels to resist sulfide stress cracking (SSC). A particular implication of utilizing these parameters is that the H2S fugacity will increase as pressure increases in a liquid-full system as can be illustrated through, for example, Ensemble Henry’s Law. This ‘beyond bubble point’ risk has been identified in rece
