Calculating Dust Retention by Coniferous Trees

To calculate the amount of dust retained by a hectare of coniferous trees, we can use the information provided in the question and apply it to the given data.

Given: - 1 hectare of deciduous trees retains 250 tons of dust per year. - Coniferous trees retain 85% less dust than deciduous trees.

Calculation

1. Calculate the amount of dust retained by coniferous trees: - 85% of 250 tons = 0.85 * 250 = 212.5 tons

Answer: - A hectare of coniferous trees retains approximately 212.5 tons of dust per year.

This calculation is based on the provided information and the percentage reduction in dust retention between deciduous and coniferous trees.
