microplastics

microplastics – sostantivo plurale

 

About 86 tonnes of microplastics are released into the environment every year in the UK from facial exfoliants alone.

The biggest concern is the ingestion of these microplastics by aquatic organisms.

Clothes washing has been widely reported as a contributor to microplastics pollution.

 

Per microplastics, microplastica, s’intendono tutti quei frammenti di plastica di dimensioni comprese fra 1 e 5 mm che inquinano le acque del nostro pianeta e si concentrano soprattutto nei mari e negli oceani. Provengono da varie fonti: processi industriali, prodotti cosmetici e sanitari, persino il comune lavaggio in lavatrice di capi in fibra sintetica.

Solo di recente si è cominciato a capire in quanti e quali modi la microplastica, oltre a inquinare corsi e masse d’acqua, rappresenta un pericolo per gli organismi animali e vegetali marini. E la preoccupazione ora è che i detriti di plastica, entrati nella catena alimentare perché ingeriti dalle specie animali acquatiche, possano avere conseguenze potenzialmente nocive anche per la salute dell’uomo. I più cinici tra noi potrebbero vederla come la meritata retribuzione per l’insaziabile fame di plastica e la mancanza di rispetto nei confronti della natura dimostrate dal genere umano.

 

Origini del termine

 

La comparsa della microplastica sulle nostre spiagge risale agli anni 1970, ma il termine microplastics è stato coniato e diffuso solo negli anni 2000.

microplastics – plural noun

About 86 tonnes of microplastics are released into the environment every year in the UK from facial exfoliants alone.

The biggest concern is the ingestion of these microplastics by aquatic organisms.

Clothes washing has been widely reported as a contributor to microplastics pollution.

 

Microplastics are small pieces of plastic that find their way into the water system and from there into the rivers and oceans, where they accumulate in vast quantities. They come from a wide range of sources, including industrial processes, microbeads from health and beauty products, and even clothes made from artificial fibres washed in domestic washing machines.

 

Microplastics are generally defined as pieces of plastic less than five millimetres long and it is becoming evident that, in addition to creating pollution on a huge scale, they can be harmful to aquatic life in ways that are just beginning to be fully understood. Of further concern is that having entered the food chain after being mistaken for food by marine creatures, they could be consumed by humans with possible detrimental effects on human health. Some might regard this as no more than poetic justice for humanity’s insatiable and growing appetite for plastic combined with our tendency to use the oceans as a giant waste disposal system.

 

Origin

Microplastics were first seen on beaches in the 1970s but the term itself is of recent coinage, coming into common use in the late 2000s.
