Assessment of chemical and physical risk factors in greenhouses

Crop production in greenhouses needs the use of chemicals and requires high levels of temperature and moisture content in order to ensure high levels of crop production. This can cause risks to the health of the operators, especially if they are not equipped with protection devices. To measure the levels of VOC (Volatile Organic Compounds), toxic gases, moisture content and ambient temperature and to process the measured data, an electronic system, equipped with a data logger and a photo ionisation sensor, was used. The results of these measurements gave useful indications about the health risks for the operators.
