The evidence is clear: microplastics have contaminated every corner of the globe. We can’t escape exposure to these tiny bits of plastic (less than 5mm across) in the environment, which includes the homes where people spend most of their time.
Recent research has discovered microplastics in the blood of humans. However, the question of harm to humans remains unresolved. Despite concerns that some substances in microplastics could cause cancer or damage our DNA, we still have a poor grasp of the true risks of harm.
