Explanation:

Both statements regarding particulate pollutants are correct.

Algae can be considered as a viable particulate pollutant. In certain environmental conditions, such as excess nutrient runoff, algae can proliferate rapidly, leading to algal blooms. These blooms can release particulate matter into the air, especially during drying and windblown conditions, contributing to air pollution.

Scrubbers are indeed used to clean air from both dusts and gases. They work by passing polluted air through a wet or dry packing material, where the pollutants are removed. Wet scrubbers are effective in removing both gases and particulates, while dry scrubbers primarily target gases but can also handle some particulate matter.

Therefore, both statements 1 and 2 are correct.
