Aim of activity 13.3 Class 10 Science
Activity 15.3 requires us to discuss the presence and causes of pesticides in food items that are packaged.
The solution to activity 13.3
Question 1. What do you think would be the source of pesticides in these food items?
- The primary source of pesticides in food items is agricultural practices.
- Farmers use these chemicals to protect their crops from pests and diseases.
- Pesticides are absorbed by plants from the soil along with water and minerals.
- They can also be taken up by aquatic plants and animals from water bodies.
Question 2. Could pesticides get into our bodies from this source through other food products too?
Yes, pesticides can enter our bodies from these sources through other food products.
Pesticides are commonly used in agriculture to protect crops from pests and diseases. However, these chemicals, which are often non-biodegradable, can find their way into our food chain.
They are washed down into the soil or water bodies, absorbed by plants and aquatic organisms, and eventually reach us when we consume these organisms. This process is known as biological magnification.
Discuss what methods could be applied to reduce our intake of pesticides.
There are several methods we can apply.
- First, we can minimize the use of chemical pesticides in our agricultural practices.
- Second, we can wash fruits and vegetables thoroughly before use.
- Third, we can choose to consume organic fruits and vegetables that are grown without the use of chemical pesticides.
