Engineered nanomaterials in soils and water: how do they behave and could they pose a risk to human health?

A B A BoxallQasim Chaudhry


It is inevitable that, during their use, engineered nanoparticles will be released into soils and waters. There is therefore increasing concern over the potential impacts of engineered nanoparticles in the environment on aquatic and terrestrial organisms and on human health. Once released into the environment, engineered nanoparticles will aggregate to some degree; they might also associate with suspended solids, sediment, be accumulated by organisms and enter drinking water sources and food materials. These fate processes are dependent on the characteristics of the particle and the characteristics of the environmental system. A range of ecotoxicological effects have also been reported, including effects on microbes, plants, invertebrates and fish. Although available data indicate that current risks of engineered nanoparticles in the environment to environmental and human health are probably low, our knowledge of the potential impacts of engineered nanoparticles in the environment on human health is still limited. There is therefore a need for continued work to develop an understanding of the exposure levels for engineered nanoparticles in environmental systems and to begin to explore the implications of these levels in terms o...Continue Reading

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

Head And Neck Squamous Cell Carcinoma

Squamous cell carcinomas account for >90% of all tumors in the head and neck region. Head and neck squamous cell carcinoma incidence has increased dramatically recently with little improvement in patient outcomes. Here is the latest research on this aggressive malignancy.

Signaling in Adult Neurogenesis

Neural stem cells play a critical role in the production of neuronal cells in neurogenesis is of great importance. Of interest is the role signalling mechanisms in adult neurogenesis. Discover the latest research on signalling in adult neurogenesis.

Psychiatric Chronotherapy

Psychiatric Chronotherapy considers the circadian rhythm as a major factor for optimizing therapeutic efficacy of psychiatric interventions. Discover the latest research on Psychiatric Chronotherapy here.

Bone Marrow Neoplasms

Bone Marrow Neoplasms are cancers that occur in the bone marrow. Discover the latest research on Bone Marrow Neoplasms here.

IGA Glomerulonephritis

IgA glomerulonephritis is a chronic form of glomerulonephritis characterized by deposits of predominantly Iimmunoglobin A in the mesangial area. Discover the latest research on IgA glomerulonephritis here.

Cryogenic Electron Microscopy

Cryogenic electron microscopy (Cryo-EM) allows the determination of biological macromolecules and their assemblies at a near-atomic resolution. Here is the latest research.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.
