Small plastic fragments found in intertidal sediment from world’s largest shipbreaking zone: over 80 mg/kg of sediment

Plastic pollution is a threat to marine ecosystems, as plastics are persistent, toxic and can accumulate up the food chain. This study assessed the abundance of small pieces of plastic in Alang, India. The authors found, on average, 81 mg of small plastic fragments per kg of sediment, which they say is the direct result of shipbreaking.

High gold prices drive expansion of mining activity in the Amazon forest of Peru

Gold mining areas in the Peruvian Amazon rainforest expanded from under 10 000 hectares in 1999 to over 50 000 hectares by 2012, and now destroys more forest than agriculture and logging combined, new research has shown. Using high-resolution satellite imaging, researchers estimated gold mining areas to be twice as large as estimated by previous studies, which did not include the combined effects of thousands of small, mainly illicit, mining operations.

This is likely to have caused population declines in these commercially important species, the researchers conclude.

Nitrous oxide is now top ozone-layer damaging emission

According to new research, emissions of anthropogenic nitrous oxide (N2O) are now causing more damage to the ozone layer than those of any controlled ozone depleting substance and this is projected to remain the case for the rest of this century. The study suggests that limiting N2O emissions could help both the recovery of the ozone layer and tackle climate change.

A new study has analysed trends in ozone levels in the European troposphere from 1996 to 2005.

New ozone hole discovered over the Arctic

For the first time, scientists have identified an ‘ozone hole’ over the Arctic, in addition to the well-known ozone hole over the Antarctic.

The authors warn that this is likely to happen again, although it is presently difficult to predict when this might be.

Black carbon and ozone pollutants may be driving tropical expansion

Man-made pollutants may be responsible for the expansion of the tropics in the northern hemisphere, according to recent research.

Low emission zones may need complementary local traffic policies

Low emission zones (LEZs) that restrict old vehicles in city centres may need implementation in combination with other traffic policies to have greater impacts on air quality, according to new research.

Quantification of the interactive effects of ozone pollution on health and ecosystems

For the first time, researchers have quantified the link between heat waves, the removal of ozone from the atmosphere by vegetation, ground-level ozone concentrations and its impact on human health and ecosystems. They found that high ozone levels, enhanced by effectively ‘turning-off’ the loss of ozone to the vegetated surface, could have caused around 460 extra deaths during a UK heat wave in 2006. In contrast, the heat wave protected ecosystems from ozone damage as plants absorbed less ozone from the atmosphere.ozone damage as plants absorbed less ozone from the atmosphere.

A new study has estimated that nitrogen oxide (NOx) and harmful ozone levels will fall significantly in Europe, by 2030, if all current and planned air quality legislation is implemented.

CO2 and ozone affect wheat’s nutritional quality

Predicting the effects of changing levels of atmospheric gases on agricultural crops is vital to ensuring food security under global environmental change. As well as yield, impacts on the nutritional value of crops must be considered. A new study has now shown that increased ozone decreases yields and increases the proportion of protein in the grain. Conversly, elevated levels of CO2 boosts wheat yields, but it also reduces protein proportion in two different ways.

Ozone levels will vary across Europe under future climate change

Climate change affects air pollution at a regional and local scale. A recent study has reassessed the latest findings and suggests that climate change will increase ozone concentrations by about 3 parts per billion (ppb) in central and western Europe in the year 2050 if emissions from human activities remain at present-day levels. However, if emissions increase, ozone concentrations could increase by 16 ppb for much of Europe.

Mediterranean ozone levels fall in rural areas, but rise in cities

Air pollution legislation has led to reduced ozone pollution in rural areas in western Mediterranean countries; however, levels in urban and suburban areas are still increasing, new research concludes.

Should critical levels of plant ozone exposure be lower?

‘Critical levels’ of ozone exposure for plants, above which significant adverse effects may occur, are currently calculated by examining ozone’s impacts on only a small number of species. However, researchers have now compared this measure with a new approach which examines all species in a group, and defines the critical levels as the concentration at which 5% of species are affected. These critical levels, which may be more suitable for semi-natural ecosystems, are stricter than current standards.
