What factor may increase the risk of toxicity in emulsifiable concentrates?

A high concentration of active ingredients in emulsifiable concentrates is a significant factor that may increase the risk of toxicity. Emulsifiable concentrates are formulated to dissolve in water and can contain high concentrations of active substances that are designed to target specific pests or diseases. When the concentration of these active ingredients is elevated, the potential for adverse effects on non-target organisms, including humans and beneficial wildlife, increases. This heightened concentration can lead to greater exposure risks during application, handling, or if there is a spill or leak.

Furthermore, higher concentrations can also result in more potent biological effects, leading to increased toxicity. This is particularly critical in the context of safely using pesticides, as understanding the implications of concentration helps users manage risks effectively.

In contrast, a low concentration of active ingredients would generally be safer and entail a reduced risk of toxicity. The presence of inert ingredients usually serves to enhance the formulation without contributing to toxicity, while biodegradable solvents are often preferred for their lower environmental impact, further mitigating toxicity risks.
