Chapter 2: Problem 21

Certain plant species but also (modified) chitosan can take up some elements very selectively and concentrate them. What are possible risks and opportunities of this specific uptake behavior? See Dodson et al. (2012).

Short Answer

Expert verified

Answer: Some potential opportunities associated with selective uptake behavior include bioremediation, resource recovery, and improved agriculture. However, risks associated with this behavior involve potential health risks from toxic element accumulation, environmental risks due to elemental imbalances in ecosystems, and unintended consequences from uncontrolled or improper use of selective uptake methods.

Step by step solution

Identifying selective uptake behavior

Begin by understanding the concept of selective uptake behavior. In this context, it refers to certain plant species and modified chitosan being able to absorb and concentrate specific elements selectively, rather than taking up all available elements indiscriminately.

Opportunities for selective uptake behavior

Now let's discuss the potential opportunities that this selective uptake behavior can offer: 1. Bioremediation: This can be an effective method for the removal and recovery of toxic elements from contaminated environments like soil and water. 2. Resource recovery: The concentrated elements can be exploited for various industrial applications and can assist in sustainable use of resources. 3. Agriculture: Plant species with selective uptake behavior can be used to enrich soil with essential elements, improving overall soil fertility and promoting healthy plant growth.

Risks associated with selective uptake behavior

With the potential opportunities, there are also some risks associated with this selective uptake behavior: 1. Health risks: The accumulation of toxic elements in edible plant parts could lead to potential health risks for humans and animals. 2. Environmental risks: The buildup of specific elements in certain areas due to the selective uptake behavior might lead to an imbalance in the ecosystem. 3. Unintended consequences: Uncontrolled or improper use of plant species or modified chitosan with selective uptake behavior might lead to negative consequences, such as unpredicted interactions with other species or exacerbation of existing environmental issues.

Conclusion

In conclusion, the selective uptake behavior of certain plant species and modified chitosan presents both risks and opportunities. Understanding the behavior and finding the right balance in implementing it can potentially lead to effective bioremediation, resource recovery, and agricultural benefits while minimizing the negative consequences for human health and the environment.
