TLDR
In this article, a 10,000-year-old Greenland ice core was melted and representative water drops were transferred to coated grids in a clean room environment, where they were observed to be carbon nanotubes and related fullerene-like nanocrystal forms.About:

Occurrence, behavior and effects of nanoparticles in the environment.
Bernd Nowack,Thomas D. Bucheli +1 more
TL;DR: This review presents an overview of the classes of NP relevant to the environment and summarizes their formation, emission, occurrence and fate in the environment.
Journal ArticleDOI
A Review of Carbon Nanotube Toxicity and Assessment of Potential Occupational and Environmental Health Risks
TL;DR: It is speculated that exposure to combustion-generated MWCNTs in fine PM may play a significant role in air pollution-related cardiopulmonary diseases by pollutants, and the possible mechanisms of CNT pathogenesis in the lung and the impact of residual metals and other impurities on the toxicological manifestations are presented.
Journal ArticleDOI
Aggregation and deposition of engineered nanomaterials in aquatic environments: role of physicochemical interactions.
TL;DR: In this review, colloidal forces governing nanoparticle deposition and aggregation are outlined, and essential equations used to assess particle-particle and particle-surface interactions, along with Hamaker constants for specific nanoparticles and the attributes exclusive to nanoscale particle interactions, are described.
Journal ArticleDOI
Nanoparticles: structure, properties, preparation and behaviour in environmental media
TL;DR: The key properties of nanoparticles and their preparation are discussed and how these factors can play a role in determining their fate and behaviour in the natural environment are discussed.
Journal ArticleDOI
Ecotoxicity and analysis of nanomaterials in the aquatic environment.
TL;DR: This review addresses hazards associated and ecotoxicological data on nanomaterials in the aquatic environment, main weaknesses in ecot toxicological approaches, controversies and future needs are discussed.

Impairment of alveolar macrophage phagocytosis by ultrafine particles.
TL;DR: It is demonstrated that ultrafine particles impair macrophage phagocytosis to a greater extent than fine particles compared on a mass basis.

The size distribution of microparticles from selected segments of the Greenland Ice Core Project ice core representing different climatic periods
TL;DR: In this paper, the size distribution of insoluble microparticles (dust) in the particle size interval 0.4-6.0 μm radius has been measured in more than 1400 samples from the Greenland Ice Core Project (GRIP) deep ice core from Summit, Greenland.

High Abrasion Resistance with Sparse Mineralization: Copper Biomineral in Worm Jaws
TL;DR: Using nanoindentation, it is shown that the copper-based biomineral atacamite has a structural role and enhances hardness and stiffness in the jaws of the marine bloodworm Glycera dibranchiata.
Journal ArticleDOI
Fractal geometry of carbonaceous aggregates from an urban aerosol
TL;DR: Fractal analysis of transmission electron microscope (TEM) images provides a means of quantifying morphologic variations among aggregates and relating them to mechanisms of formation as mentioned in this paper. But the analysis is limited to aerosol data.

Pesticides: Transatlantic Movements in the Northeast Trades
TL;DR: The amnounts of pesticides contributed to the tropical Atlantic by the trade winds appear to be comparable to those carried to the sea by major river systems.
