Question

In the polluted environment "receptor" is the (a) damagcd part of the human system (b) damagcd part of the animals (c) affected system by contaminants (d) adversely affected medium by the pollutants

Short answer

Option (c): affected system by contaminants.

Step-by-step solution

Understand the term 'receptor' in pollution context

In environmental science, a 'receptor' refers to the entity that is exposed to and affected by pollutants or contaminants.

Review the options provided

The options given are: (a) damaged part of the human system, (b) damaged part of the animals, (c) affected system by contaminants, (d) adversely affected medium by the pollutants.

Identify the correct definition

The correct definition is the entity or system that is affected by exposure to contaminants or pollutants. This definition matches option (c).

Confirm the answer

Check that option (c) aligns with our understanding of 'receptor' as the affected system by contaminants.

Key concepts

environmental science

Environmental science is the study of how natural and human-made environments interact. It involves examining physical, chemical, and biological processes that occur in nature.
For example, environmental scientists study water cycles, plant and animal interactions, and pollution.
This field helps us understand how human activities like pollution and deforestation impact the natural world.

pollution effects

Pollution effects refer to the negative impacts that various pollutants have on the environment and living organisms.
Pollutants can be chemical substances or forms of energy like noise or heat.
Some common effects of pollution include:

• Air pollution causing respiratory issues in humans and animals.
• Water pollution leading to unsafe drinking water and harming aquatic life.
• Soil pollution affecting plant growth and food safety.

contaminants exposure

Contaminants exposure occurs when living organisms come into contact with pollutants.
Contaminants can enter the environment through various activities, such as industrial processes, agricultural practices, and urban development.
The degree of exposure can vary based on factors like:

• Concentration of the contaminant.
• Duration of exposure.
• Pathways through which it enters the organism (e.g., inhalation, ingestion).

affected systems

Affected systems are the parts of the environment or organisms that are harmed by contaminants.
These can include:

• Human health systems, such as the respiratory or nervous systems.
• Animal health, affecting wildlife populations and biodiversity.
• Natural environments, like forests, rivers, and oceans, which can suffer ecological damages.

Understanding the impact on these systems is crucial for mitigating pollution and protecting environmental health.
