Project examples

This page describes five work and consultancy projects conducted by Dr Pascal Haefliger to illustrate the type of services that can be provided by Health & Environment Consulting. Do not hesitate to contact us to discuss your projects and needs.

1. Assessment of risks to human health from a lead contamination in soil
In 2012, Dr Pascal Haefliger was contracted by Swiss cantonal authorities to assess the health risks from the contamination of soil with lead in the vicinity of a former industrial site. The contract included the evaluation of the current risks for the health of the population living in the contaminated area, the preparation of an assessment report, the presentation and discussion of the evaluation results with the local population, and the formulation of public health recommendations for the management of identified health risks.

2. Teaching environmental health and chemical safety to university students
Pascal Haefliger regularly gives lectures on environmental health and chemical safety to university medicine and public health students. Lectures are tailored to the interests and levels of expertise of the audience, and usually include general principles, practical examples, and interactive group activities.

3. Preparation of technical documents on analytical methods to measure lead in blood and lead in paint.
In 2010, Dr Pascal Haefliger was mandated by WHO to prepare two guides on analytical methods for measuring lead in blood and lead in paint. These documents aimed at informing environmental health personnel and policy-makers who are not laboratory specialists but who may need to develop plans for blood and paint testing. These guides had to be concise, understandable to non-specialists, and include practical considerations for selecting the most appropriate method for various requirements and contexts. The final documents, reviewed by international experts, are available online at:

4. Investigation and management of an environmental health emergency
In 2008, hundreds of children living in Thiaroye sur Mer, Senegal, suffered from severe lead poisoning due to a massive environmental contamination resulting from artisanal lead battery recycling. Following an official request for assistance, the World Health Organization (WHO) deployed an international emergency response team to support Senegalese authorities in investigating and responding to this incident. Dr Haefliger coordinated and directed the environmental and public health aspects of this mission on the field. Findings enabled to assess the extent of the contamination, identify pathways of human exposure, estimate risks to health, and propose and initiate risk mitigation measures. Following the mission, Dr Haefliger led the preparation of a scientific publication describing the incident and discussing the global health problem posed by artisanal lead battery recycling.

5. Assessment of national capacities for the sound management of chemicals
Following a chemical incident that occurred in Mongolia in 2008, Dr Haefliger was involved in the assessment of the Mongolian capacities for the sound management of chemicals. During a 2-week mission, more than 50 relevant governmental, private and public entities were evaluated with regards to their roles and responsibilities in the following chemical safety domains: a) Policies, legislation and arrangements; b) Coordination and cooperation; c) Information need, production and dissemination; d) Risk and impact assessment; e) Risk management; f) Implementation and enforcement; g) Emergency response; h) Capacity development and training; and i) Monitoring and evaluation. The results of the assessment were used to provide recommendations and develop an action plan to strengthen Mongolian capacities for the sound management of chemicals.
