A new study has examined the toxic effects of silver nanoparticles on plants. Using a range of spectroscopic and imaging techniques, the researchers demonstrate how silver nanoparticles can reduce the growth of wheat, as well as interfere with genes that help the plant deal with pathogens and stress.

Silver nanoparticles present in the effluent from waste-water treatment plants could have toxic effects on aquatic organisms, new research suggests. The lab-based study tested the effects of nanoparticle-containing effluent on several crustacean and algae species. The researchers observed that epibenthic crustaceans (those living in or on sediments at the bottom of water bodies) were the most sensitive; notably, a 20–45% higher death rate was observed compared with those exposed to nanoparticle-free effluent.

Fine particles in the air produced by road transport trap more radiation in the earth's atmosphere than previously estimated, and therefore may contribute more to global warming than realised, according to new research. In contrast, the impact of particles from shipping appears to reflect more radiation than previously thought, whilst the effect of particles from aviation is comparatively small.

Ultrafine particles emitted from a waste incinerator plant in Italy have been characterised in a recent study. The results suggest that a fabric filter was efficient at cleaning particulate matter from the exhaust gases. Data produced by the study could go on to be used by scientists studying the potential health impacts of ultrafine particles.

Researchers have measured the presence of carbon nanoparticles in the air over the Mediterranean Sea. The results revealed that higher concentrations are found in air that has moved over areas of industrial activity, and that the lowest layers of the atmosphere are likely to be responsible for transporting the nanoparticles.

Fires in forests contaminated by the Chernobyl nuclear accident could lead to areas of Europe and Russia being exposed to further radioactive fallout, new research has found. The study examined the spread of the fallout and the health effects on people and animals under three different scenarios: 10, 50 and 100% of the forests being burnt.

The chances of a child developing Autism Spectrum Disorder (ASD) are higher if the mother is exposed to high levels of fine particulate air pollution during pregnancy, a recent study suggests. This increased risk was associated specifically with exposure in the last three months of pregnancy, the researchers found.

Researchers have assessed the phyto-toxic effects of copper nanoparticles on vegetables grown within urban gardens, comparing increasing doses of these nanoparticles to simulate potential aerial deposition to extreme pollution of CuO-NP in a range of increasing exposure periods. Lettuce and cabbage absorbed high amounts of copper nanoparticles, after 15 days of exposure, which interfered with photosynthesis, respiration and also reduced growth. Under the specific exposure conditions of the study the researchers indicate that metal nanoparticles could lead to potential health risks to humans from the contamination of crops from pollution.

Air pollution via small particulate matter (PM) from diesel fumes and other sources is of growing concern in urban areas, and contributes to poor air quality. In European urban areas, PM pollution often exceeds World Health Organization (WHO) safe levels for human wellbeing. In response to this, the European Commission has encouraged researchers to develop a low-cost, sustainable material that captures these particles in order to clean the air1. This study created a new PM capture material using sustainable chemical processes where the carbon footprint and energy use of the production process of the remediation material is taken into account. The newly developed porous material is called ‘SUNSPACE’ (an acronym derived from ‘(SUstaiNable materials Synthesized from By-products and Alginates for Clean air and better Environment’).
