Micro- and nanoplastics are small plastic particles that can arise from the breakdown of discarded plastic materials, wear from regular use, or even spills of plastic manufacturing materials such as nurdles. Microplastics typically range in size from about 5 millimeters down to the lower micrometer scale, while nanoplastics extend to the smallest particles, with sizes down to 1 nanometer. Both types have now been found in every biome on the planet and can be detected in the air, in water, and even in the organs of the human body. Taking a broad look at where micro- and nanoplastics are coming from, the processes that are causing their distribution in the environment and their overall fate and impact Microplastics and Nanoplastics in the Environment is an ideal resource for researchers interested in environmental pollutants in general, plastic pollution in particular and pollution control, mitigation or remediation.
