All Flashcards
What are the effects of DDT on birds of prey?
Eggshell thinning, leading to population declines.
What are the health effects of dioxin exposure?
Cancer, immune system suppression, and reproductive problems.
What are the health effects of PCB exposure?
Cancer, developmental issues, and neurological problems.
What are the consequences of POPs accumulating in fatty tissues?
Bioaccumulation and biomagnification, leading to higher concentrations in top predators.
What is the impact of POPs on human endocrine systems?
Hormonal imbalances, leading to developmental and reproductive problems.
What are the effects of Chlordane exposure?
Neurological effects, liver and kidney damage, and cancer.
What are the effects of HCB exposure?
Liver and kidney damage, and cancer.
What are the environmental consequences of POPs in the Hudson River?
Fish advisories and health concerns due to PCB contamination.
What are the human health consequences of Agent Orange exposure?
Health problems for veterans due to dioxin contamination.
What is the effect of POPs on neurological development?
POPs can cause neurological issues, especially in developing fetuses and young children.
What makes POPs dangerous?
They persist, bioaccumulate, biomagnify, and are toxic.
Why are POPs fat-soluble?
They accumulate in fatty tissues of organisms.
What is the significance of long-range transport of POPs?
POPs can travel across continents via air and water, affecting distant ecosystems.
How do POPs disrupt endocrine systems?
They mimic or block hormones, leading to hormonal imbalances.
Why are birds of prey vulnerable to DDT?
DDT causes eggshell thinning, leading to reproductive failure.
What is the role of air in POPs transport?
Wind carries POPs far from their source, enabling widespread contamination.
What is the role of water in POPs transport?
Rivers and oceans move POPs around, spreading contamination to aquatic ecosystems.
Why is the Stockholm Convention important?
It provides a framework for global cooperation to reduce and eliminate POPs.
How do POPs affect human health?
They can cause cancer, neurological issues, and developmental problems.
What are the major sources of POPs?
Industrial processes, pesticides, and combustion byproducts.
What is the goal of the Stockholm Convention?
To eliminate or restrict the production and use of POPs globally.
What is Annex A of the Stockholm Convention?
Lists POPs banned for production and use (e.g., DDT, PCBs).
What is Annex B of the Stockholm Convention?
Lists POPs restricted for production and use (e.g., Chlordane).
What is Annex C of the Stockholm Convention?
Lists chemicals under review for future inclusion as POPs.
How often does the COP meet for the Stockholm Convention?
Every two years to review and assess implementation.
