Two Decades of Air Pollution Health Risk Assessment: Insights From the Use of WHO's AirQ and AirQ+ Tools.

Objectives: We evaluated studies that used the World Health Organization's (WHO) AirQ and AirQ+ tools for air pollution (AP) health risk assessment (HRA) and provided best practice suggestions for future assessments.

Methods: We performed a comprehensive review of studies using WHO's AirQ and AirQ+ tools, searching several databases for relevant articles, reports, and theses from inception to Dec 31, 2022.

Results: We identified 286 studies that met our criteria.

Age at death during the Covid-19 lockdown in French metropolitan regions: a non parametric quantile regression approach.

Background: Lockdowns have been implemented to limit the number of hospitalisations and deaths during the first wave of 2019 coronavirus disease. These measures may have affected differently death characteristics, such age and sex. France was one of the hardest hit countries in Europe with a decreasing east-west gradient in excess mortality.

Regional excess mortality in France during COVID-19 pandemic: the first three epidemic periods (March 2020-June 2021).

Background: This study aimed to describe the mortality excess during the three first epidemic periods of COVID-19 in all regions of France.

Methods: Two complementary approaches were implemented. First, we described the number of death of patients infected with or diagnosed with COVID-19 in health care (HC) and medico-social (MS) institutions.

On the supra-linearity of the relationship between air pollution, mortality and hospital admission in 18 French cities.

Purpose: Understanding the relationship between an environmental determinant and a given health outcome is key to inform public health policies. The short-term mortality and morbidity responses to outdoor air pollutants are traditionally assessed as a log-linear relationship, but few studies suggest a possible deviation from linearity. This paper investigates the shape of the relationship between ozone, NO and fine particulate matter (PM and PM), mortality and hospital admissions in 18 French cities between 2000 and 2017.

Influence of exposure assessment methods on associations between long-term exposure to outdoor fine particulate matter and risk of cancer in the French cohort Gazel.

Background: Many studies investigated the relationship between outdoor fine particulate matter (PM) and cancer. While they generally indicated positive associations, results have not been fully consistent, possibly because of the diversity of methods used to assess exposure.

Objectives: To investigate how using different PM exposure assessment methods influences risk estimates in the large French general population-based Gazel cohort (20,625 participants at enrollment) with a 26-year follow-up with complete residential histories.
