Consider the following statements:Statement-I: Most Herbicides are tox...
Explanation:
Statement-I: Most Herbicides are toxic to mammals
- Herbicides are chemicals used to kill unwanted plants, including weeds.
- Many herbicides are designed to target specific biological processes in plants, making them toxic to mammals as well.
- Exposure to herbicides can lead to various health issues in mammals, including humans, such as skin irritation, respiratory problems, and even more serious conditions like cancer.
Statement-II: Herbicides become concentrated in the food web
- When herbicides are sprayed on plants, they can be absorbed by the plants and accumulate in their tissues.
- Animals that consume these plants can then ingest the herbicides, leading to bioaccumulation.
- As animals higher up in the food chain consume these contaminated plants or other animals, the concentration of herbicides increases, resulting in biomagnification.
Correct Answer:
- Both Statement-I and Statement-II are correct and Statement-II is the correct explanation for Statement-I.
- The toxicity of herbicides to mammals and their accumulation in the food web are interconnected phenomena, with herbicides posing a risk to both human health and environmental ecosystems.

Consider the following statements:Statement-I: Most Herbicides are tox...
- Most herbicides are toxic to mammals but are not as persistent as organo-chlorides. These chemicals decompose in a few months. Like organo-chlorides, these too become concentrated in the food web. Some herbicides cause birth defects. Studies show that cornfields sprayed with herbicides are more prone to insect attack and plant disease than fields that are weeded manually.
- Pesticides and herbicides represent only a very small portion of widespread chemical pollution. A large number of other compounds that are used regularly in chemical and industrial processes for manufacturing activities are finally released in the atmosphere in one or other form. Hence, option (a) is the correct answer
