Question

The Stockholm Convention aims to protect human health and environment from which types of pollutants?

• A. Ozone-depleting substances
• B. Greenhouse gases
• C. Heavy metals
• D. Persistent organic pollutants

Hint:

• The Stockholm Convention specifically targets Persistent Organic Pollutants (POPs).
• POPs are toxic chemicals that are persistent, bioaccumulative, and prone to long-range transport.
• Examples include certain pesticides (DDT), industrial chemicals (PCBs), and byproducts (dioxins).
• The convention aims to eliminate or restrict their production, use, trade, and release.

Answer 1

The Correct Option is D

The Stockholm Convention is an international environmental treaty with the aim of safeguarding human health and the environment from the deleterious effects of specific chemical substances. These substances are categorized as Persistent Organic Pollutants (POPs). POPs are characterized by their persistence in the environment, capability of long-range transport, bioaccumulation in humans and wildlife, and significant adverse effects on human health and ecosystems.

Pollutant Type	Description
Ozone-depleting substances	Chemicals that contribute to the depletion of the Earth's ozone layer.
Greenhouse gases	Gases that trap heat in the atmosphere, contributing to global warming.
Heavy metals	Metallic elements with high atomic weights, potentially toxic.
Persistent organic pollutants	Chemicals that are environmentally persistent, bioaccumulative, and toxic.

Considering the categories, the Stockholm Convention specifically addresses the issue of Persistent Organic Pollutants. It aims to eliminate or restrict the production and use of these substances due to their environmental persistence and ability to cause significant health issues.

Therefore, the correct answer is: Persistent organic pollutants.
