Background: Exposure assessment represents a major challenge for studies on the relation between pesticides and health.
Objective: We developed a method combining information from crop-exposure matrices (CEMs) and land use data, in order to compute indices of environmental and occupational pesticide exposure. We illustrate our approach using French data (1979-2010).
The relatively recent development of industries working with nanomaterials has created challenges for exposure assessment. In this article, we propose a relatively simple approach to assessing nanomaterial exposures for the purposes of epidemiological studies of workers in these industries. This method consists of an onsite industrial hygiene visit of facilities carried out individually and a description of workstations where nano-objects and their agglomerates and aggregates (NOAA) are present using a standardized tool, the Onsite technical logbook.

Article Synopsis
- The study analyzed the effects of repeated g-FOBT screening on the positive predictive value (PPV) for advanced colorectal neoplasia, including advanced adenomas (AA) and colorectal cancer (CRC), in 98,031 average-risk adults aged 50-74.
- Results showed a PPV of 24.5%, higher in men than women (30.7% vs 17.7%), with an increase in detection rates for proximal AA and CRC in subsequent screenings.
- Factors like age, gender, and prior screening episodes were significantly linked to higher detection rates, particularly with more advanced-stage cancers found in later screenings, highlighting the importance of regular monitoring.
Background: The French national screening programme for colorectal cancer (CRC) was rolled out nationwide from 2008. It targets men and women aged 50-74 who are invited every 2 years to perform a guaiac faecal occult blood test, followed, if positive, by a colonoscopy. This paper presents the evaluation of the programme for the 46 French districts that conducted a comprehensive screening campaign during 2008-2009, targeting 9.
