🔬 The Decomposition and Half-Life of Toxins

The second paragraph focuses on the decomposition of organic toxins and the concept of half-life. It explains that organic toxins, such as those found in plants and animals, will degrade over time due to the weak chemical bonds within their carbon and hydrogen atoms. In contrast, inorganic toxins like lead or arsenic, which are naturally present in the Earth's crust, do not decompose in the traditional sense but have a half-life, the time it takes for half of the substance to decay. The paragraph also touches on the potential dangers of using expired synthetic toxins, such as pesticides, which can become more harmful over time. It concludes by emphasizing the importance of understanding the differences in how various toxins are affected by time.
