Final answer:
Yes, the black substance on the tissue is most likely carbon black. It is not harmful to the soil in small amounts and can even have beneficial effects like improving soil fertility.
Step-by-step explanation:
Yes, the black substance that transfers onto the tissue is most likely carbon black. Carbon black is a form of elemental carbon that is used as a pigment in various products, including tires. It is produced by the incomplete combustion of hydrocarbon materials.
Carbon black is not harmful to the soil in small amounts. In fact, it can even have some beneficial effects. It can improve the soil's fertility by increasing its ability to retain water and nutrients, and it can also enhance soil microbial activity.
However, it's important to note that excessive amounts of carbon black or prolonged exposure to it can have detrimental effects on the environment and human health. It is best to minimize the release of carbon black into the environment and dispose of used tires properly.
