Waste water treatment plants (WWTPs) are receptors for the cumulative loading of microplastics (MPs) derived from industry, landfill, domestic wastewater and stormwater. The partitioning MPs through settlement processes results in majority becoming entrained sewage sludge. This study characterized sludge samples seven WWTPs Ireland which use anaerobic digestion (AD), thermal drying (TD), or lime stabilization (LS) processes. Abundances ranged 4196 to 15 385 particles kg-1 (dry weight)....
Macroalgae have played an important role in coastal communities for centuries. In the past, they been harvested and gathered from shorelines around world traditional uses such as food, animal feed a crude fertilizer (marine manure). Today, seaweeds are used multitude of applications with expanding global industries based on hydrocolloids, cosmetics food supplements, also potential biofuel source. However, approximately 10 000 algal species reported to exist, only small number commercially...
Microplastics are a ubiquitous pollutant in our seas today and known to have detrimental effects on variety of organisms. Over the past decade numerous studies documented microplastic ingestion by marine species with more recent investigations focussing secondary impacts ecosystem processes. However, few so far examined mesopelagic fish which one most abundant pelagic groups oceans through their vertical migrations contribute significantly rapid transport carbon nutrients deep sea....
Understanding source elements of the ocean plastic crisis is key to effective pollution reduction management and policy. The ubiquity microplastic (MP) fibres in oceans considered derive primarily from clothing released grey water. Microplastic degraded widely flushed personal care textile products (wet wipes sanitary towels) have not been clearly identified aquatic systems date. Unregulated hygiene product labelling fails identify materials. This study demonstrated that white MP sediments...
In development since 1996, AlgaeBase (http//www.algaebase.org) is an on-line database providing free access to authoritative taxonomic, distributional and nomenclatural information of more than 135,000 names species infraspecific taxa algae set in the context a taxonomic hierarchy. The project was initially funded by Higher Education Authority, Department Science (Ireland) European Union (the SeaweedAfrica Project), recently industry sponsor Ireland (Ocean Harvest Technology) various...
Climate change impacts on food security will involve negative crop yields, and potentially the nutritional quality of staple crops. Common bean is most important grain legume for human diets nutrition worldwide. We demonstrate by modeling that majority current common growing areas in southeastern Africa become unsuitable cultivation year 2050. further reductions yields available varieties a field trial climate analogue site future predicted drought conditions. Little known regarding impact...
Management strategies for the safe disposal of contaminated dredged marine sediment constitute a global-scale environmental issue. The stabilization/solidification method was investigated as sustainable approach to recycling construction material. A systematic study factors affecting mechanical performance and contaminant release performed. physico-chemical variables selected assess potential re-use treated with Ordinary Portland cement (OPC) Ground Granulated Blast Furnace Slag (GGBS) in an...
In this study, the biokinetics of autotrophic denitrification with biogenic S0 (ADBIOS) for treatment nitrogen pollution in wastewaters were investigated. The used S0, a by-product gas desulfurization, was an elemental microcrystalline orthorhombic sulfur median size 4.69 µm and specific surface area 3.38 m2/g, which made particularly reactive bioavailable. During denitritation, biomass enriched on nitrite (NO2–) capable degrading up to 240 mg/l NO2–-N denitritation activity 339.5 mg...
Enrichment of nutrients and metals in seawater associated with anthropogenic activities can threaten aquatic ecosystems. Consequently, nutrient metal concentrations are parameters used to define water quality. The European Union's Water Framework Directive (WFD) goes further than a contaminant-based approach utilises indices assess the Ecological Status (ES) transitional bodies (e.g. estuaries lagoons). One assessment is based upon abundance opportunistic Ulva species, as an indication...
Abstract The use of Pt(IV) complexes as pro-drugs that are activated by intracellular reduction is a widely investigated approach to overcome the limitations Pt(II) anticancer agents. A series ten mono- and bis-carboxylated with axial indole-3-acetic acid (IAA) indole-3-propionic (IPA) ligands were synthesized characterized elemental analysis, ESI-MS, FT-IR, 1 H 195 Pt NMR spectroscopy. Cellular uptake, DNA platination cytotoxicity against panel human tumor cell lines evaluated. All able...
