Toxicity reference values (TRVs)

Published on 20/12/2024

As part of its missions and under the French National Environmental & Health Action Plan (2004-2008), the Agency began a national programme on TRVs in 2004 with the aim of building solid French expertise that could be shared by the various competent authorities in this area.

huiles essentielles Risks in using essential oils and precautions to be taken

Updated on 23/12/2024

Whether applied to the skin, used in sprays and diffusers or ingested, essential oils have become everyday products. However, they contain a variable mixture of substances that can be toxic to our health. We take a look at the issue to better understand the potential effects of essential oils.

Homme Animaux One Health for living beings and ecosystems

Updated on 19/11/2024

The One Health concept aims to promote a multidisciplinary, holistic approach to health issues. Where did this approach come from and what does it involve? How does ANSES apply it when carrying out its activities?

Chlordécone Risks of dietary exposure to chlordecone in the French Caribbean

Updated on 27/09/2024

Chlordecone is a pesticide that can pose a risk to human health. It was used in banana plantations in the French Caribbean until 1993. Being very persistent, it has permanently contaminated the soil and water, and even today has an impact on crops and livestock production. Since the early 2000s, ANSES has been working to improve knowledge on exposure of the French Caribbean population to this contaminant and the associated health risks. In particular, it has made recommendations on the consumption of locally produced food.

Eau Développement durable How can non-potable water be used? What are the health risks?

Updated on 23/09/2024

With water resources becoming increasingly scarce, there is growing interest in the different ways in which non-potable water such as wastewater and rainwater can be used. These include irrigating crops, watering gardens and green spaces, cleaning floors and cars, or flushing toilets. However, this water may contain pathogenic micro-organisms and potentially toxic organic or inorganic chemicals. Here is an update on the authorised uses and ANSES's recommendations.

moutons Five questions on bluetongue

Updated on 11/09/2024

Bluetongue is a viral disease of ruminants, and does not affect humans or food. It is transmitted by biting midges and can cause major economic losses in livestock farming. Vaccination is the most effective means of prevention, but is expensive. Here is a profile of the disease and an overview of the work of ANSES, a leading player in the fight against this virus.

Moustique Tigre The tiger mosquito

Updated on 11/09/2024

Native to the tropical forests of Southeast Asia, the tiger mosquito (Aedes albopictus) has adapted to many different environments, particularly urban ones, colonising a vast array of containers in which it lays its eggs in small volumes of water. The tiger mosquito is an opportunistic anthropophilic species which bites humans and can transmit viruses such as dengue, chikungunya and Zika. Because of this, it represents a major public health challenge. Below you will find an introduction to a mosquito that we haven’t heard the last from.

cosmétiques Endocrine disruptors, a scientific challenge

Updated on 15/07/2024

Endocrine disruptors are substances that can interfere with our hormonal system and cause adverse effects. Given the multiple sources of exposure, scientists need to understand the role played by these substances in the development of certain diseases.

PFAS Understanding more about exposure to and the hazards of PFASs

Updated on 23/07/2024

Per- and polyfluoroalkyl substances, collectively known as PFASs, are chemicals that share one main characteristic: they are very persistent in the environment. This persistence means they can be found in all environmental compartments. Given the very large number of substances involved, the major challenge is to prioritise actions to prevent or limit health and environmental risks. PFASs have been a topic of interest for ANSES for a long time. The Agency carries out several activities in this area: characterising the PFASs most commonly found, determining the levels of contamination to which people are exposed, and identifying the most toxic substances. Below is an overview of this work.

tique hyalomma Risk of emergence of Crimean-Congo haemorrhagic fever in France

Updated on 29/04/2024

Crimean-Congo haemorrhagic fever is a potentially fatal disease in humans, transmitted by certain ticks. Although no indigenous human cases have yet been reported in France, there is a real risk of this disease emerging in the country.

zoom sur PFAS PFASs: very persistent chemicals

Updated on 07/06/2024

Per- and polyfluoroalkyl substances, better known as PFASs, are chemicals whose specific properties mean that they are used in many everyday products. Extremely persistent, PFASs are found in all environmental compartments and people can therefore be exposed via air, food and drinking water, or through the use of various everyday products and objects. Below we review the applicable regulations and the health and environmental challenges associated with this class of substances.
