Applications in Medicine, Industry, and the Environment
Start with the big picture
The lesson connects the chemistry of Group 15 elements with practical uses and consequences. Nitrogen and its compounds feature in inert atmospheres, cryogenic applications, fertilizer manufacture, medical treatment, and air pollution. Phosphates support biological structures and energy transfer while serving as fertilizer and detergent ingredients; excess runoff can harm freshwater ecosystems. Other sections address phosphoric acid, semiconductor materials, arsenic trioxide in cancer treatment and the hazards of arsenic exposure, wood preservatives, antimony flame retardants and antiparasitic medicines, and bismuth compounds. Together, these examples show why evaluating an application requires considering both its intended benefit and its effects on people and the environment.
What you'll learn
- Describe industrial and medical applications of nitrogen and its compounds.
- Explain biological, industrial, and environmental roles of phosphates.
- Identify selected uses and hazards of arsenic- and antimony-containing materials.
- Relate Group 15 compounds to environmental effects and human health risks.
