Green Chemistry and DDT

A synthetic pesticide that was widely used to control insects, but was later banned due to its harmful effects on the environment and human health.

A toxic heavy metal that is sometimes used as a skin whitening agent in cosmetics, but is highly damaging to human health.

A field of chemistry focused on designing chemical products and processes that minimize or eliminate harmful effects on humans and the environment.

The goal of green chemistry is to create safer chemicals and develop more sustainable methods for producing them, while minimizing waste and pollution.

Green chemistry is a chemical approach that aims to prevent pollution and reduce the risk of environmental damage by implementing eco-friendly practices throughout the chemical lifecycle.

Green chemistry emphasizes the development of chemical technologies that prioritize the use of renewable resources, minimize energy consumption, and generate minimal waste.

A key principle of green chemistry is to design chemical products that are inherently safer for humans and the environment, minimizing the need for hazardous chemicals.

Green chemistry promotes using renewable resources, such as plant-based materials or biomass, instead of depleting fossil fuels, which have a significant environmental impact.

A synthetic insecticide widely used after World War II for pest control, especially in fighting malaria.

The use of DDT resulted in the widespread death of birds like bald eagles, peregrine falcons, and pelicans.

The accumulation of substances like DDT in organisms as they move up the food chain, resulting in higher concentrations at higher trophic levels.

Rachel Carson's book, published in 1962, that drew attention to the harmful effects of pesticides like DDT on the environment.

The concept of designing chemical processes and products that minimize or eliminate harmful effects on human health and the environment.

The aim of Green Chemistry is to promote the creation of environmentally friendly processes and products, reducing dependence on harmful chemicals.

The use of pesticides like DDT highlighted the need for a more sustainable approach to chemical production and use.

Green Chemistry seeks to minimize the generation of waste and emissions, aiming for environmentally responsible and sustainable manufacturing.

Preventing waste before it is created is prioritized over managing waste after it is produced.
