Greenhouses Large Source Of Toxins

Greenhouses could be poisoning their local environment, according to new research from the Swedish University of Agricultural Sciences.

In streams downriver from the commercial farms they found levels of toxins almost one thousand times higher than legal limits. 78% of those toxins were made up of fungicides and insecticides. Most affected is the southern county of Skåne(Scania), where much of Sweden's market gardening industry is based.

Researcher Jenny Kreuger says that greenhouses have often been considered as "closed" environments, so that the authorities have been less strict when it comes to looking at effects on the surrounding water table, compared with the demands on farmers using open fields.
