Velsen-Zuid's air quality reflects the North Sea Canal position adjacent to the Tata Steel IJmuiden steelworks, one of Europe's largest integrated steel plants generating elevated PM10, SO₂, and heavy metals alongside vehicle traffic on the A22. The North Sea westerlies provide some maritime ventilation, but the steelworks' extraordinary scale relative to the local population makes the IJmuiden-Velsen area consistently one of the Netherlands' most industrially impacted municipal environments throughout the year.
