Which of the following is an appropriate material to absorb a liquid pesticide spill?

Using kitty litter as an absorbent material for a liquid pesticide spill is appropriate due to its high absorbency and ability to clump. When spills occur, especially with chemicals like pesticides, it is crucial to use effective materials that can safely and efficiently absorb the liquid. Kitty litter is designed to absorb moisture and can contain and solidify spilled liquids, making the cleanup process easier and minimizing the risk of environmental contamination.

While sand can absorb some liquids, it is less effective than kitty litter in terms of clumping and making the cleanup manageable. Water, on the other hand, is not suitable for cleaning up pesticide spills, as it could dilute the pesticide, spreading it further and potentially causing more harm. Paper towels are absorbent but may not be sufficient for larger spills, and they can also become saturated quickly, requiring frequent replacement. Therefore, kitty litter stands out as the best choice for effectively managing a liquid pesticide spill.
