Coto Doñana threatened by agricultural contaminants

One of Europe’s most important wildlife areas under threat from agro-chemicals

April 2009. Eleven years after the Aznalcóllar pyrite mine rupture, in the north of the Coto Donana National Park (Huelva), the contamination caused from the spill seems to have been overcome. However Spanish researchers have evaluated the environmental quality of the park‘s environment with crayfish as bio-indicators. This methodology, the most groundbreaking of its kind in the world, demonstrates that contaminants from intensive agriculture being carried out close to the Park are the main threat in this Biosphere Reserve and are already affecting the Puebla del Río and Matochal rice paddies.

The six million cubic metre acid water and toxic pyrite mud spill in 1998 did not have dramatic effects on the Coto Donana National Park because it did not enter the park limits. There is, however, still concern in the area due to agricultural activity and the use of pesticides in harvests close to the protected Natural Park, which could threaten the Park’s environmental quality.

ScienceDaily (Nov. 27, 2009) — The Aznalcóllar mining accident more than 11 years ago, which contaminated part of the Doñana National Park, also damaged reptile habitat there. Now a team of Spanish researchers, who have been studying the reptile community since 2000, have shown, by setting up artificial refuges, that the disappearance of natural refuges had a serious impact on lizard and snake numbers: here.

Spanish wetland facing destruction as farming starves it of water: here.

An environmentally valuable expanse of Spanish wetlands that dried up through mismanagement of water resources and drought is once again awash with water due to heavy rainfall, an official said Tuesday. Over 1,200 hectares (3,000 acres) of the wetlands of the Tablas de Daimiel National Park are flooded, the highest level since 1997, up from just 67 hectares on January 7, a park spokesman said: here.

September 2010. Researchers from the University of Seville (US) have detected active pharmaceutical substances for the first time in the waters of the Doñana National Park and its surrounding areas. The results suggest eco-toxicological risks for aquatic organisms. The scientists recommend that advanced technologies should be used to treat urban waste water in order to remove these compounds: here.

Seville, Spain – Spain’s management of the renowned bird migration refuge at Doñana comes under review tomorrow, as international experts begin assessing multiple threats from illegal farming and proposed dredging and oil pipeline construction: here.

  1. BASF breakdown pollutes Rhine

    Germany: Chemical giant BASF has said that a “breakdown” at its headquarters in western Germany had sent 10 tons of an industrial chemical spewing into the River Rhine.

    BASF asserted that the leak had been stopped and posed no danger to humans or the environment.

    The company said that the chemical HPN can be harmful to a person’s eyes, but would be so diluted by water in the Rhine that it “posed no risk to humans or nature.”
