While the metalworks brought local people steady, well-paid work, the production took a great toll on public health. In 2001, the WHO named Veles one of the most polluted towns in the world, due to the soil and air pollution from the smelting of metals such as zinc and lead in local factories.
The last metalworks closed in 2003, after 30 years in service, taking 1,200 jobs with it. Despite high unemployment, locals supported the decision, and a plan by Macedonia's Metrudhem, a subsidiary of the Swiss metals company Mineco, to restart the factory in 2011 was shelved after a
public protest.
