2. Environmental Quality: Monitoring and Assessment
The chapter discusses the classification of chemicals of concern, focusing on pollutant types and their implications for human health and environmental safety. It categorizes these substances based on both their chemical properties, such as aliphatic and aromatic compounds, and their applications across various industries. The necessity of monitoring and assessing these chemicals is emphasized to ensure public safety and mitigate potential health risks associated with exposure.

What we have learnt
- Chemicals can be classified based on their structure and applications.
- Aliphatic and aromatic compounds represent fundamental classifications within organic chemistry.
- Chemical monitoring is essential for prioritizing pollutants to track their presence and assess their risks.
Key Concepts
- -- Aliphatic Compounds
- Organic compounds consisting of carbon and hydrogen, characterized by straight or branched chains or non-aromatic rings.
- -- Aromatic Compounds
- Compounds containing one or more benzene rings, often with distinct stability and reactivity due to resonance.
- -- Polyaromatic Hydrocarbons
- Complex organic compounds that consist of multiple fused aromatic rings, which can pose environmental and health risks.
- -- Chemical of Concern
- Any chemical that poses potential human health risks and needs to be monitored due to its toxicity or environmental impact.
- -- Volatile Organic Compounds (VOCs)
- Organic chemicals that have a high vapor pressure at room temperature, making them significant pollutants in industrial processes.
