Street and land pollution in Barcelona

Abril 7, 2008 · Archivado en Street/land pollution

 
 
 Causes Consequences
• Factory closures

• Soil pollution from toxic waste 

 • Derelict areas include sites that have formerly been used as factories, etc., but have been closed down; the areas remain unused and undeveloped for any other purposes. 

• Industrial sites deposit pollutants on the ground they occupy and by leaks from tanks and underground pipes. The pollution comes to light when industrial areas are dismantled and given over to other uses, La Llagosta (now the Olympic Village) and the coastal strip of Sant Adrià and Besòs-Montgat provide examples of this problem.
• Domestic waste Street waste storage bins are a characteristic of Barcelona streets. The most densely populated districts often have refuse spilling from the bins onto the streets.  • This creates offensive odours, is an eyesore and a health hazard, particularly in the summer heat. Collections are made at night, creating a great deal of noise.
• Sewer system’s capacity can be surpassed when there is torrential rain • Causes surface flooding and direct discharges to the sea via the overflows. Raw sewage is washed onto the beaches

Air pollution in Barcelona

Abril 7, 2008 · Archivado en Air pollution

 
 Causes Consequences
• Traffic and industry The industries in the Besòs area have largely been replaced by service companies, producing a marked drop in atmospheric emissions for the whole areaPrivate traffic is the main producer of pollution in the Barcelona Region. The number of private vehicles on the road grows every year. Although older vehicles are being replaced by newer, less polluting ones, the increase in the number of cars on the road has more than offset cleaner combustion. The building of ring roads has increased the use of private vehicles.

• Gas-fired heating systems also cause air pollution

•  Illegal burning of industrial materials (tyres, for example) which is currently done almost anywhere in the area.

  • The main environmental problems associated with air emissions are harm to human health, the acidification and eutrophication of water and soils, and damage to natural ecosystems, buildings and crops.

• Barcelona, summer period: It is estimated that over 66% of the population are affected by ozone levels in excess of 180ug/m3, and that over 66% of the population have been exposed to maximum NO2 levels in excess of 200 um/m3. These figures are above the recommended WHO levels.
