Plastics are ubiquitous in the oceans and constitute suitable matrices for bacterial attachment growth. Understanding biofouling mechanisms is a key issue to assessing ecological impacts fate of plastics marine environment. In this study, we investigated different steps plastic colonization polyolefin-based plastics, on first one hand, including conventional low-density polyethylene (PE), additivated PE with pro-oxidant (OXO) artificially-aged OXO (AA-OXO); polyester,...
The thin film of life that inhabits all plastics in the oceans, so-called “plastisphere,” has multiple effects on fate and impacts plastic marine environment. Here, we aimed to evaluate relative influence size, shape, chemical composition, environmental changes such as a phytoplankton bloom shaping plastisphere abundance, diversity activity. Polyethylene (PE) polylactide acid (PLA) together with glass controls forms meso-debris (18 mm diameter) large-microplastics (LMP; 3 diameter), well...
Plastic pollution has become a worldwide concern. It was demonstrated that plastic breaks down to nanoscale particles in the environment, forming so-called nanoplastics. is important understand their ecological impact, but structure not elucidated. In this original work, we characterize microstructure of oceanic polyethylene debris and compare it nonweathered objects. Cross sections are analyzed by several emergent mapping techniques. We highlight deep modifications within layer few hundred...
Intensive observations in the northeast Indian Ocean (Bay of Bengal) during presouthwest and monsoon seasons 1991 reveal that freshwater discharge from rivers subcontinent exerts dominant control over total carbon dioxide (TCO 2 ) pCO distributions surface waters. Low levels occur within low‐salinity zones, with a large area northwestern bay acting as sink for atmospheric CO . Only part observed variation can be accounted by effect salinity, biological production supported external nutrient...
The “Plastics, Environment and Health” research network (groupement de recherche, GDR) created in 2019 gathers the French scientific community working on plastic pollution all environments (soil, air, water) their impact ecosystems human health. objective is to rapidly increase knowledge by supporting collaboration of researchers from different fields such as ecotoxicology, chemistry, physics, microbiology, oceanography social science. Research carried out at each stage life cycle, (from...
Abstract Objectives The aims of the study are to investigate effects latitude, settlement type, age, and sex on prevalence vitamin D deficiency disease in Roman Empire using human skeletal remains from cemetery sites (1st 6th cent. AD). Materials Methods Data 2,787 individuals (1,143 subadults, 1,644 adults) 18 cemeteries associated with 15 different settlements Mediterranean north‐western Europe were analyzed. Vitamin (rickets, osteomalacia) was identified standard paleopathological...
Seasonal (winter monsoon, intermonsoon and southwest monsoon) interannual (between monsoon seasons of 1995 1996) variations in total carbon dioxide (TCO2) partial pressure CO2 (pCO2) were studied the central eastern Arabian Sea as a part JGOFS (India) Programme. The pCO2 values computed from results coulometric TCO2 spectrophotometric pH measurements. variability is evident with changing circulation biological production. In all seasons, higher surface waters Sea, except along Indian coast...
Extensive optical, physical, chemical, and biochemical measurements made simultaneously in the northwest Indian Ocean reveal occurrence of an intermediate nepheloid layer (INL) invariably associated with secondary nitrite maximum. Maxima particulate protein activity respiratory electron transport system (ETS) are also found within INL. Since INL persists long distances from continental margin offshore intensification, it may not be related to material resuspended along margin. An apparent...
The roughness of fracture surfaces exhibits self-affinity for a wide variety materials and loading conditions. universality the range scales over which this regime extends are still debated. topography these is however often investigated with finite contact probe. In case, we show that correlation function can only be measured down to length scale $\ensuremath{\Delta}{x}_{c}$ depends on probe size $R$, Hurst exponent $\ensuremath{\zeta}$ surface its topothesy $l$, spurious behavior at...
