The greenhouse gas nitrous oxide is on the rise

Most of us know nitrous oxide as “laughing gas”, used for its anaesthetic effects. But nitrous oxide is also one of the main stratospheric ozone depleting substances – and we are releasing more of it into the atmosphere than previously thought.

Greenhouse gas levels are constantly rising

The most important greenhouse gases monitored by NILU – The Norwegian Institute for Air Research continued to rise in 2017. Levels have now reached new records both at Svalbard and in Aust-Agder in Norway. Both CO2, methane and nitrous oxide continue to increase in both Southern Norway and Svalbard, and there is no sign of reduction or flattening in this trend.

NILU measures volatile organic compounds (VOCs) in Chile

Over a period of 4 months, NILU has measured the concentrations of volatile organic compounds (VOCs) in the air in the Chilean municipalities of Quintero-Puchuncaví and Concón in the Valparaíso region. The measurements were carried out on behalf of the Chilean Ministry of the Environment. So far, the measurement results show no sign that VOC emissions from the industrial area affect the air quality in neighbouring residential areas.

Mediciones de NILU de componentes orgánicos volátiles (COVs) en Chile

NILU ha realizado mediciones de compuestos orgánicos volátiles (COVs) durante un periodo de cuatro meses en los municipios de Quintero-Puchuncaví y Concón, ambos en la región de Valparaíso. Estas mediciones fueron comisionadas por el Ministerio de Medio Ambiente de Chile. Los resultados obtenidos hasta el momento no indican que las emisiones de COVs de la zona industrial afecten la calidad del aire en las áreas residenciales cercanas.

Air quality in Europe still poses danger to health and environment

The European air quality is slowly improving, but as the Air Quality in Europe 2018 Report shows, air pollution continues to exceed European Union and World Health Organization limits and guidelines. Thus, air pollution is still posing a danger to human health and the environment.

Scientists call for stronger management of PFASs

August 31st, 2018: More than thirty scientists from all over the world, in conjunction with regulators from agencies across the globe, have jointly outlined a set of needs, goals, and actions to help assess and manage the diverse and widely used group of per- and polyfluoroalkyl substances (PFASs) in the future.

Setting up the “laughing gas” budget

From the NILU Annual Report 2017: “Laughing gas” sounds harmless enough. Known also as nitrous oxide, it is in fact the third most important greenhouse gas in the atmosphere, and no laughing matter.

NILU to lead EEA’s topic center on air quality and noise problems

Air quality in Europe is getting better. However, a significant proportion of Europe’s population still lives in cities and areas where at times, noise and air pollution may lead to health problems. Norwegian scientists are now tasked with leading the work of compiling the knowledge base the decision-makers in Europe need to give us better air and quality of life.

Data revolution in urban atmospheric research

From the NILU Annual Report 2017: During the last decade, the need for information and data has exploded, and this “data revolution” has not stopped short of science. In environmental research, data have become more and more important – to the point that scientists now even know what your fireplace looks like.

Environmental forensics – chasing environmental offenders

From the NILU annual report 2017: Oil spills, tanker accidents, chemical disasters – suddenly materials are released into the environment, potentially harming both humans and nature. Is it possible for scientists to trace the environmental offenders?

How to measure air quality at the ends of the World

From the NILU Annual Report 2017: From the Zeppelin Observatory at 79 degrees north to Trollhaugen at 72 degrees south – NILU measures air quality at some of the world’s most inaccessible places. Why so far away?
