The unpleasant odours generated by factories, livestock farms and landfills are warning signs of serious environmental problems. However, this type of pollution is largely forgotten by legislations. The chemical engineer Rosa Arias has decided to change this and has developed an app with which citizens can register the effluvia of their environment. Also, she is the leader of an European project that is preparing the first global odour map.
If the price of oil decreases, carbon dioxide emissions increase. This is what two Spanish scientists claim after comparing the relationship between air pollution and economic development by using the real oil prices in Spain between 1874 and 2011 as an indicator. The scientists suggest a need to design new energy taxes.
Particles of less than 2.5 microns emitted by vehicles have negative repercussions for bronchiolitis, pneumonia, asthma and bronchitis in children. Should their concentrations be reduced to the levels recommended by the WHO, hospital admissions of children with these illnesses would decrease, amounting to a daily saving of 200 euros, according to calculations by researchers from the University of Seville for that city.
The health benefits of the Mediterranean diet are well-known. As well as being healthier, a recent article concludes that the menu traditionally eaten in Spain leaves less of a carbon footprint than that of the US or the United Kingdom.
The pollution of waterfowl meat and their poisoning by lead shot has dropped by 50% since this type of munitions was prohibited in wetlands in 2001. This is one of the data in a report from the Hunting Resources Research Institute, which also states that the hunters’ compliance with this mandate has been very high.
Researchers from the University of Castilla-La Mancha have developed a measurement system which permits the prediction of atmospheric pollution due to nitrogen oxides in a specific location and at a particular time. The study is supported by a massive database from urban areas in the Community of Madrid.
