Biological, physical and chemical processes contribute to ‘clean air’, a gas mix which is remarkably well balanced for life and free of toxic gases and particulates.   Oxygen is at as high a concentration as enables aerobic organisms such as us to breath easily, whilst not so high as to cause unquenchable forest fires. Carbon dioxide is plentiful enough for plants to grow, both as a source of carbon and in retaining sufficient but not too much warmth from the sun. Elements essential for life such as sulfur and iodine are transported from land to sea in the form of volatile organic compounds (VOCs). Many gases, which are toxic or harmful to life are removed by chemical and physical adsorption on solid particles (particulates) which ultimately fall out of the air under gravity as dust or rain. What is more, through a series of chemical reactions, including reactions with sunlight (photochemical reactions), the atmosphere is kept almost completely free of specific VOCs released by plants, it would seem to their own and wider advantage. For example, it has been recently established that on being bruised, leaves release VOC messengers (pheromones) that attract predators of leaf eating insects!

The European Environment Agency (EEA) reported in 2018  that air pollution was the cause of almost 50,000 premature deaths in Europe per year.  This finding pre-empted the head of the EEA agency stating "*Air pollution is an invisible killer and we need to step up our efforts to address the causes*”. Clearly preventing premature deaths is a priority and reducing air pollution could save millions of lives.  Heavy industries are a major source of VOCs and recent modification to EPA rules call for the tighter enforcement of fence line monitoring to reduce environmental emissions.  [Emily Lane](https://blog.ionscience.com/author/emily-lane) [0](https://blog.ionscience.com/environmental-and-economic#comments-listing) [![Health and Safety in Heavy Industries](https://blog.ionscience.com/hubfs/Health%20%26%20Safet%20-%20heavy%20Industries.png)](https://blog.ionscience.com/health-and-safety-in-heavy-industries) [VOC](https://blog.ionscience.com/topic/voc) [Health & Safety](https://blog.ionscience.com/topic/health-safety) 28 March 2019 ## Health and Safety in Heavy Industries   Many vapours and gases found in heavy industries pose an explosion risk. For any gas to combust it must reach its lower explosive limit (LELs). Lower explosive limits have been well established for 100s of chemicals and generally vapours from VOCs have relatively low explosion limits. For example, methane and hydrogen have LELs of 50,000 ppm and 40,000 ppm respectively whereas benzene has an LEL of only 13,000 ppm. At high concentrations VOC are also an asphyxiation risk. Like CO2, a gas all too frequently responsible for serious effects on human health, VOC are much denser than air. Therefore, where confined spaces exist it is possible for VOCs to displace oxygen and create dangerous environments.   [Emily Lane](https://blog.ionscience.com/author/emily-lane) [0](https://blog.ionscience.com/health-and-safety-in-heavy-industries#comments-listing) [![Heating,ventilation and air conditioning (HVAC)](https://blog.ionscience.com/hubfs/HVAC.png)](https://blog.ionscience.com/hvac) [VOC](https://blog.ionscience.com/topic/voc) 28 February 2019 ## Heating,ventilation and air conditioning (HVAC)     Inadequate indoor ventilation is now being combatted by intelligent heating ventilation, and air conditioning systems (HVAC). HVAC systems are now being developed and integrated in a standard way to establish a balance between adequate ventilation to prevent sickness, and also energy efficiency. Building management systems are one solution to address the balance, whereby widely distributed sensors that, for example, monitor temperature, humidity and VOCs can be used to optimise HVAC performance but minimise energy use.
