Burnt sugarcane harvesting - cardiovascular effects on a group of healthy workers, Brazil.

Background: Brazil is the world's largest producer of sugarcane. Harvest is predominantly manual, exposing workers to health risks: intense physical exertion, heat, pollutants from sugarcane burning.

Design: Panel study to evaluate the effects of burnt sugarcane harvesting on blood markers and on cardiovascular system.

Effects of biomass burning on nasal mucociliary clearance and mucus properties after sugarcane harvesting.

Objective: Biofuel from sugarcane is widely produced in developing countries and is a clean and renewable alternative source of energy. However, sugarcane harvesting is mostly performed after biomass burning. The aim of this study was to evaluate the effects of harvesting after biomass burning on nasal mucociliary clearance and the nasal mucus properties of farm workers.
