加拿大西部的山火以及此前加利福尼亚州和科罗拉多州的火灾暴露了水安全和水生生态系统所面临的威胁。 Wildfires in western Canada and previous fires in California and Colorado have revealed the threat to water security and aquatic ecosystems. 研究表明，野火会从燃烧的建筑物和汽车中携带铜、铅和锌等有毒金属，导致溪流和河流受到污染。 Research shows that wildfires can carry toxic metals, such as copper, lead, and zinc, from burning buildings and cars, leading to contamination in streams and rivers. 当野火蔓延到城市地区时，对生态系统健康和饮用水源的影响是巨大的。 When wildfires move into urban areas, the impacts on ecosystem health and drinking water sources are significant.
