["Assessment of indoor school environment and identification of measures to protect the respiratory health of school children and adolescents" in a sample of schools in Milan]. / Valutazione dei fattori di rischio indoor in ambiente scolastico e definizione delle misure per la tutela della salute respiratoria degli scolari e degli adolescenti" in un campione di scuole di Milano.

The management of indoor air quality in schools needs special attention because it has a strong impact on respiratory health of children with effects also on performance and social development. In Italy a prevention program for indoor environments is provided in the "Guidelines for the prevention of indoor risk factors for allergies and asthma in the school", developed by the Ministry of Health (G.U n. 9 del 13.01.11). In this context, the Ministry of Health has promoted the "Indoor school" project (CCM2010). The main objective of the project is the implementation of these guidelines. In this paper we report the results of the first phase of the project which assessed the knowledge of school principals on issues related to IAQ and building characteristics of the school.

Ethylenethiourea in urine as an indicator of exposure to mancozeb in vineyard workers.

In the present study, the personal exposure to mancozeb and/or ethilenethiourea (ETU) in 13 Italian vineyard workers and in 13 subjects without occupational exposure to pesticides was investigated. With this aim, the level of ETU in urine and the dermal exposure to mancozeb were determined. Baseline urinary ETU results were lower than the analytical limit of detection for all controls (<0.5 microg/g creatinine) and for ten workers (median <0.5, range <0.5-3.4 microg/g creatinine). In workers, urinary ETU was significantly increased at the end of shift (2.5, <0.5-95.2 microg/g creatinine) compared with baseline levels. End-shift urinary ETU was higher in operators using open tractors (n=7) than in those using closed tractors (n=5) (16.2 vs. 2.4 microg/g creatinine), but the difference was not significant (P=0.073). End-shift urinary ETU was positively correlated with dermal exposure to mancozeb determined both over the clothes and on the skin (Spearman's rho=0.770 and 0.702, P=0.009 and 0.024, respectively). Wine consumption positively influenced the excretion of ETU.
