“…The energetic utilization of residual products from cashew processing, such as CNS, is already a reality in some industries. In particular, combustion exhaust gases from CNS promote the release of various pollutants, such as aldehydes, ketones and polycyclic aromatic hydrocarbons (PAHs), which are capable of promoting significant pulmonary changes (JOSINO et al, 2017). As well as TPM, which can easily penetrate the respiratory system and reach the pulmonary alveoli, resulting in diseases of respiratory diseases (WHO, 2005;LEWNÉ;NILS, 2007;XIAO et al, 2011), such as COPD.…”

I. INTRODUCTION Global warming is one of the most debated environmental issues today, either because of the need for better knowledge on the subject, or for the analysis of its possible influences on life on earth. The increase in the temperature of the Earth's atmosphere coupled with the increase in the atmospheric levels of carbon dioxide (CO 2) are issues that need attention from the government and the scientific community, in an attempt to reverse the problems already present, and prevent them from increasing or become irreparable in the near future. One of the causes of global warming is the use of fossil fuels, a non-renewable resource. Faced with this problem, the search for renewable energies has grown, highlighting the use of residual biomass. Most households in China, India and sub-Saharan Africa use biomass fuel for cooking, and in rural areas of Latin America the proportion ranges from 30% to 75% (EZZATI; KAMMEN, 2002). Thus, approximately 3 billion people worldwide are exposed to biomass combustion gases compared to 1.1 billion people who smoke tobacco, suggesting that exposure to biomass smoke may be the most important overall risk factor for chronic obstructive pulmonary disease (COPD) (LOPEZ et al., 2006). As one of the largest agricultural producers in the world, Brazil has great capacity to generate energy from the residual biomass of sugarcane, rice, coffee straw and cashew nut shells (CNS). Despite the use of CNS in boiler feed for thermal energy generation in some industries, the adverse health effects of the exhaust gases from the combustion process of CNS are poorly studied, mainly in analyzes of exposure to people with pre-existing respiratory diseases such as emphysema, characterized as a COPD.

“…Additionally, a control test was also made by measuring dust concentration in the room when grinding process was not taking place. In the discussed study, the PM4.0 was used instead of the typical value of PM2.5, taking into account a phenomenon typically occurring during the process of dynamic milling that is mutual collision of particles and resulting from it gradual formation of a certain quantity of finer particles [24][25][26]. The obtained wheat middlings were analyzed on sieves in order to determine the finest fraction, i.e., with the size smaller than 0.1 mm, as well as the average particle size.…”

This work analyses the organic dust concentration during a wheat grinding process which was carried out using two types of grinders: A hammer mill and a roller mill. DustTrak II aerosol monitor was used to measure the concentration of the dust PM10 (particles with the size smaller than 10 μm), PM4.0, and PM1.0. An increase of the grain moisture to 14% resulted in the reduction in PM10 when grinding grain using the hammer mill. An inverse relationship was obtained when grain was ground using the roller mill. A smaller amount of the fraction below 0.1 mm was observed for larger diameter of the holes in the screen and smaller size of the working gap in the roller mill. For both mills, the obtained concentration of the PM10 fraction dust exceeded the acceptable level. To protect farmers health, it is necessary to use dust protection equipment or to modify the grinding technology by changing the grain moisture content and/or the grinding parameters.
