Endocrine Disruptors and Active Substances

The video discusses the regulation of hormones and the impact of endocrine disruptors, which can be natural or synthetic substances affecting the endocrine system. EFSA provides criteria for identifying these disruptors and supports EU strategies for regulation. Testing methods are crucial for identifying risks, and multiple tests are needed for accurate assessment. The video emphasizes the importance of expert judgment in evaluating potential hazards and risks in the food chain.

What are some of the critical functions regulated by hormones in the body?

• Blood circulation and immunity

• Vision and hearing

• Metabolism, growth, and mood

• Digestion and respiration

Which of the following is an example of a naturally occurring endocrine active substance?

• Pesticides

• Phytoestrogens in soya

• Plasticizers

• Dioxins

What is the key difference between endocrine active substances and endocrine disruptors?

• Endocrine disruptors are naturally occurring

• Endocrine active substances are synthetic

• Endocrine disruptors cause adverse effects

• Endocrine active substances are always harmful

According to the WHO definition, which of the following is NOT a criterion for identifying an endocrine disruptor?

• Presence of an adverse effect

• Presence of endocrine activity

• Ability to dissolve in water

• Causal relationship between endocrine activity and adverse effect

What is the significance of distinguishing between endocrine active substances and endocrine disruptors?

• To increase the use of synthetic substances

• To simplify regulatory processes

• To ensure accurate risk assessment and regulation

• To reduce the number of tests required

Why is it important to use multiple tests to identify endocrine disrupting effects?

• To avoid expert involvement

• To focus on a single aspect

• To ensure comprehensive assessment

• To save time and resources

What role do experts play in assessing endocrine disrupting effects?

• They conduct all tests

• They regulate the use of substances

• They provide expert judgment and assess the weight of evidence

• They develop new testing methods

How does EFSA assess the level of risk associated with a substance?

• By analyzing the chemical structure

• By considering the likely exposure to humans, animals, and the environment

• By measuring the substance's solubility

• By evaluating its market demand

What is the main reason the risk of amygdalin in apricot stones is considered low?

• It is not toxic

• It is not consumed by humans

• It is beneficial for health

• It is easily broken down

What is a hazard in the context of endocrine substances?

• A substance that is always safe

• A potential threat due to intrinsic properties

• A substance that is always harmful

• A chemical that is beneficial
