Organic matter decomposition in the globally widespread coniferous forests has an important role carbon cycle, and cellulose is especially this respect because most abundant polysaccharide plant litter. Cellulose was 10 times faster fungi-dominated litter of Picea abies forest than bacteria-dominated soil. In soil, added (13)C-labelled main source microbial respiration preferentially accumulated fungal biomass induced proliferation. contrast, litter, bacterial showed higher labelling after...
Environmental water quality monitoring aims to provide the data required for safeguarding environment against adverse biological effects from multiple chemical contamination arising anthropogenic diffuse emissions and point sources. Here, we integrate experience of international EU-funded project SOLUTIONS shift focus a few legacy chemicals complex mixtures, identify relevant drivers toxic effects. Monitoring serves range purposes, control ecological status compliance specific uses, such as...
Per- and polyfluoroalkyl substances (PFAS) are a group of synthetic compounds used in commercial applications, household products, industrial processes. The concern around the environmental persistence, bioaccumulation, toxicity this vast contaminant class continues to rise. We conducted review scientific literature compare patterns PFAS bioaccumulation marine organisms identify potential concern. occurrence data seawater, sediments, several taxa was analyzed from studies published between...
About 3 billion new tires are produced each year and about 800 million become waste annually. Global dependence upon from natural rubber petroleum-based compounds represents a persistent complex environmental problem with only partial often-times, ineffective solutions. Tire emissions may be in the form of whole tires, tire particles, chemical compounds, which is transported through various atmospheric, terrestrial, aquatic routes built environments. Production use generates multiple heavy...
Abstract Phototoxicity resulting from photoactivated polycyclic aromatic hydrocarbons (PAHs) has been reported in the literature for a variety of freshwater organisms. The magnitude increase PAH toxicity often exceeds factor 100. In marine environment phototoxicity to organisms not individual or complex mixtures PAHs. this study, larvae and juveniles bivalve, Mulinia lateralis , mysid shrimp, Mysidopsis bahia were exposed known phototoxic PAHs (anthracene, fluoranthene, pyrene), as well...
This article provides practical guidance on the use of passive sampling methods (PSMs) that target freely dissolved concentration (Cfree ) for improved exposure assessment hydrophobic organic chemicals in sediments. Primary considerations selecting a PSM specific application include clear delineation measurement goals Cfree , whether laboratory-based "ex situ" and/or field-based "in is desired, and ultimately which best-suited to fulfill objectives. Guidelines proper calibration validation...
Climate change can have a marked effect on the distribution and abundance of some species, as well their interspecific interactions. In 1992, before ecological effects anthropogenic climate had developed into topical research field, Hersteinsson Macdonald published seminal paper hypothesizing that northern limit red fox (Vulpes vulpes) is determined by food availability ultimately climate, while southern Arctic lagopus) competition with larger fox. This hypothesis has inspired extensive in...
Abstract. The existence of 4 alleles phosphoglucomutase (PGM 1 ) In human red cell lysates has been demonstrated by isoelectric focusing confirming earlier work Bark et al. and Kühnl A survey 101 the inheritance these in 24 families are now described.
The behavior and fate of nanoparticles (NPs) in the marine environment are largely unknown potentially have important environmental human health implications. aggregation NPs greatly influenced by their interactions with seawater dissolved organic carbon (DOC). In present study, stability 30-nm-diameter silver (AgNPs) capped citrate polyvinylpyrrolidone (PVP; AgNP-citrate AgNP-PVP) 21-nm-diameter titanium dioxide (TiO(2)) as affected salinity DOC were investigated measuring hydrodynamic...
The toxicity, bioaccumulation, and biotransformation of citrate polyvinylpyrrolidone (PVP) coated silver nanoparticles (NPs) (AgNP-citrate AgNP-PVP) in marine organisms via sediment exposure was investigated. Results from 7-d toxicity tests indicate that AgNP-citrate AgNP-PVP did not exhibit to the amphipod (Ampelisca abdita) mysid (Americamysis bahia) at ≤75 mg/kg dry wt. A 28-d bioaccumulation study showed Ag significantly accumulated polychaete Nereis virens (N. virens) AgNP-citrate, a...
Passive samplers were deployed to the seafloor at a marine Superfund site on Palos Verdes Shelf, California, USA, and used determine water concentrations of persistent organic pollutants (POPs) in surface sediments near-bottom water. A model Fickian diffusion across thin boundary layer sediment-water interface was calculate flux contaminants due molecular diffusion. Concentrations four stations DDE, DDD, DDMU, selected PCB congeners from column. Three passive sampling materials compared: PE...
Strategies are provided for making robust measurements of engineered nanomaterial bioaccumulation across a broad range organisms.
Abstract Microscopic organisms are often overlooked in traditional diversity assessments due to the difficulty of identifying them based on morphology. Metabarcoding is a method for rapidly where Environmental DNA (eDNA) used as template. However, legacy problematically detected from no longer environment during sampling. RNA (eRNA), which only produced by living organisms, can also be collected environmental samples and metabarcoding. The aim this study was determine differences community...
