Lethal, behavioral, growth and developmental toxicities of alkyl-PAHs and non-alkyl PAHs to early-life stage of brine shrimp, Artemia parthenogenetica

open access: yesEcotoxicology and Environmental Safety, 2021
Alkyl-PAHs are the predominant form of PAHs in crude oils which are supposed to demonstrate different toxicities compared to non-alkyl PAHs. Little information is available about the toxicity of alkyl-PAHs on marine Artemia.

Polystyrene microplastics alter bioaccumulation, and physiological and histopathological toxicities of cadmium in the polychaete Perinereis aibuhitensis

open access: yesFrontiers in Marine Science, 2022
Heavy metal (HM) pollution in the marine environment has been of concern for decades. The potential impact of HMs carried by emerging marine pollutants such as microplastics (MPs) has attracted attention only in recent years.

Microplastics in Invasive Freshwater Mussels (Dreissena sp.): Spatiotemporal Variation and Occurrence With Chemical Contaminants

open access: yesFrontiers in Marine Science, 2021
Invasive zebra and quagga mussels (Dreissena spp.) in the Great Lakes of North America are biomonitors for chemical contaminants, but are also exposed to microplastics (<5 mm).

Sorting Debris

open access: yesCoSMO, 2023
Thinking about modernist urbanism as a period in architecture with potential for the future of cities has been outside the canon for several decades. But from a critical viewpoint, the postmodern stance on modernist mass housing continuously failed to dissociate high modernist urbanism as a unified architectural project from its socio-political ...

Management status and policy direction of submerged marine debris for improvement of port environment in Korea

open access: yesOpen Geosciences, 2022
As the issue of marine waste is emerging around the world, it is urgent to come up with measures to manage marine waste. This study examined the status of the collection project of submerged marine debris (SMD) undertaken to improve the environment of ...

Satellite laser ranging at ultra-high PRF of hundreds of kilohertz all day

open access: yesFrontiers in Physics, 2022
Satellite laser ranging (SLR) had been operated at a pulse repetition frequency (PRF) from ∼10 Hz to 10 kHz; the ultra-high PRF of SLR (UH-SLR) is a trend of development.

The Thickness of Talus Deposits in the Periglacial Area of SW Spitsbergen (Fugleberget Mountainside) in the Light of Slope Development Theories

open access: yesLand, 2022
Periglacial slopes are susceptible to recent climate change. The rate of morphogenetic processes depends on numerous factors. The most important of these is the warming of the air and ground, increased precipitation (extreme rainfall in particular), and ...

Debris Thickness of Glaciers in the Everest Area (Nepal Himalaya) Derived from Satellite Imagery Using a Nonlinear Energy Balance Model [PDF]

open access: yes, 2014
Debris thickness is an important characteristic of debris-covered glaciers in the Everest region of the Himalayas. The debris thickness controls the melt rates of the glaciers, which has large implications for hydrologic models, the glaciers' response to

Chemical-Physical Model of Gaseous Mercury Emissions from the Demolition Waste of an Abandoned Mercury Metallurgical Plant

open access: yesApplied Sciences, 2023
Soils from decommissioned Hg mine sites usually exhibit high levels of total mercury concentration. This work examines the behavior of mercury in the atmosphere on samples of contaminated debris of a demolished metallurgical plant present in La Soterraña

Metallicity of solar-type stars with debris discs and planets [PDF]

open access: yes, 2012
Around 16% of the solar-like stars in our neighbourhood show IR-excesses due to debris discs and a fraction of them are known to host planets. We aim to determine in a homogeneous way the metallicity of a sample of stars with known debris discs and ...
