What is released when peat is burned?

Answered by Andrew Fritz

When peat is burned, it releases a variety of substances into the atmosphere. One of the most significant is carbon dioxide, a greenhouse gas that contributes to climate change. Peat fires can release large amounts of carbon dioxide, as the organic material in peat is rich in carbon. This is a major concern because the combustion of fossil fuels, such as peat, is a significant contributor to the increase in greenhouse gases in our atmosphere.

In addition to carbon dioxide, peat fires also release other greenhouse gases such as methane and nitrous oxide. Methane is a potent greenhouse gas, with a much higher warming potential than carbon dioxide. Nitrous oxide is also a powerful greenhouse gas and is released when the nitrogen in peat is burned. These additional greenhouse gases further contribute to the warming of our planet and the exacerbation of climate change.

One particular concern with peat fires is the release of mercury into the atmosphere. Mercury is a toxic heavy metal that can have serious health implications for humans and wildlife. Peat fires release mercury into the atmosphere at a rate 15 times greater than upland forests. This is particularly worrisome because mercury can bioaccumulate in the food chain, leading to higher concentrations in fish and other seafood that humans consume. Long-term exposure to mercury can have detrimental effects on the nervous system, especially in developing fetuses and young children.

Personally, I have witnessed the effects of peat fires during my travels to regions where peatlands are prevalent. The thick smoke and haze caused by these fires can be suffocating and make it difficult to breathe. The air quality deteriorates significantly, affecting not only the health of the local population but also the wildlife in the area. The release of greenhouse gases and mercury from peat fires is a stark reminder of the environmental consequences of our actions and the need to find sustainable alternatives.

When peat is burned, it releases carbon dioxide, methane, nitrous oxide, and mercury into the atmosphere. These substances contribute to climate change, air pollution, and pose health risks to humans and wildlife. The impact of peat fires on the environment and human health should not be underestimated, and efforts should be made to find alternative practices that minimize the use of peat and prevent its combustion.
