Particulate matter is not only dangerous for humans, but also for bees and other insects. New studies show that high concentrations of particulate matter in the air impair the ability of bees to perceive floral odours. As a result, they visit fewer flowers, which in turn leads to a decline in pollination. Without pollination, there is no fruit, no vegetables and no cereals. It's a worrying cycle that could have serious consequences for our ecosystem and ultimately our food supply.
Fine dust particles are extremely small and can therefore easily penetrate the bodies of insects. There they cause damage to health, ranging from inflammation of the respiratory tract to cancer. In this respect, it is not only us humans who suffer from particulate matter pollution, but also bees - animals in general.
Particulate matter pollution caused by various human activities is one of the main problems for bees and other insects today. In addition to traffic, fireworks on New Year's Eve and Easter bonfires are an important source of particulate matter. They significantly affect air quality every year and contribute to climate change. They also lead to a massive release of particulate matter into the atmosphere, which is harmful to both human and animal health and the environment. This could also lead to the expansion or establishment of new low emission zones.
It is important to emphasise that the effects of particulate matter are not limited to bees and other insects. Particulate matter also contributes to global warming and has a negative impact on various areas of the environment. It can disrupt the natural water cycle, impair soil fertility and lead to acidification of water bodies.
But there is also hope. As Klaus Brunsmeier, board member of BUND NRW, emphasises, every individual can do something to improve the situation. Creating habitats for insects in the city, greening roofs and façades and making green spaces insect-friendly are just some of the measures that can be taken.
