The Wider Impact Of Chemistry Flashcards
How does chemistry affect everyday life?
Chemistry is involved in the production of medicines, food, energy, cleaning products, and many other consumer goods.
Give an example of how chemical research has improved quality of life.
The development of pharmaceuticals, such as antibiotics and vaccines, has significantly increased human life expectancy and quality of life.
What is environmental chemistry?
Environmental chemistry studies chemical processes in the environment and how pollutants affect air, water, and soil quality.
How can chemical waste impact the environment?
Improper disposal of chemical waste can lead to contamination of water sources, soil degradation, and adverse effects on ecosystems.
What is meant by sustainable chemistry?
Sustainable chemistry focuses on designing products and processes that reduce or eliminate the use and generation of hazardous substances.
How does green chemistry contribute to environmental protection?
Green chemistry promotes the development of chemical processes that minimize waste, energy use, and environmental impact.
Define chemical risk assessment.
Chemical risk assessment involves evaluating the potential harm chemicals may pose to human health and the environment, leading to informed regulatory decisions.
“What role do regulations play in the chemical industry?”
Regulations ensure the safe production, handling, and disposal of chemicals to protect public health and the environment.
How does the use of fossil fuels relate to the wider impact of chemistry?
The combustion of fossil fuels releases greenhouse gases, contributing to climate change and air pollution.
What are some potential hazards of chemical exposure in industry?
Chemical exposure can lead to acute poisoning, long-term health issues such as cancer, and environmental contamination.
Explain the concept of life-cycle analysis in chemistry.
Life-cycle analysis assesses the environmental impact of a product or process from raw material extraction to disposal, ensuring more sustainable practices.
How does chemistry contribute to advances in medicine?
Chemistry is central to drug design, diagnostics, and the development of novel therapies, improving healthcare outcomes.
