Which risk increased with the use of mercury amalgamation in early gold mining techniques?

💡 Explanation

When mercury amalgamation was used, mercury would bond to gold particles, but excess mercury was released into the environment because it was challenging to contain, contaminating waterways. Therefore, mercury contamination increased, rather than poisoning, collapse, or explosions, which relate to different mining hazards.
