Chemical Suppressants More Effective Than Water for Dust Control

A study found that chemical dust suppressants are better than water at reducing dust on roads.

The chemicals can keep dust down for about six hours, while water only works for a few minutes.

However, chemicals can be harmful if not used carefully.

Experts say chemicals should be used in places with little traffic or movement.

Water is still used more because it's safer and easier to apply.

The study was done in Delhi to see how well chemicals work at construction sites.

Both methods have their pros and cons, but chemicals are more effective in the short term.
