Sewage sludge brings a lot of microplastics to Estonian gardens.

Uuring näitab, et haljastuses ja põllumajanduses kasutatav reoveesete sisaldab palju mikroplasti ja muid kahjulikke aineid.

The study shows that sewage sludge used in landscaping and agriculture contains a lot of microplastics and other harmful substances.

Reoveepuhastamisel tekib palju setteid. Eestis . See on selleks reguleeritud, et .

A lot of sludge is generated during wastewater treatment. In Estonia, it is used as fertilizer. This is regulated to protect the environment and people.

Margit Heinlaan uuris kolleegidega, kui palju mikroplasti on reoveepuhastusjaamade vees. Mikroplast on väiksed plastitükid, mis ei lahustu vees. Uuringus vaadati kuut erinevat puhastusjaama.

Margit Heinlaan and her colleagues investigated how much microplastic is in the water of wastewater treatment plants. Microplastics are small pieces of plastic that do not dissolve in water. The study looked at six different treatment plants.

Uuringu tulemused näitasid, et puhastusjaamad eemaldavad veest 99,6–99,8% plastiosakesi. See on väga hea tulemus. Kuid heitvees on ikkagi väikesed kogused mikroplasti.

The study results showed that treatment plants remove 99.6–99.8% of plastic particles from water. This is a very good result. However, there are still small amounts of microplastics in the effluent.

Mikroplast jõuab puhastatud veest reoveesettesse. Eestis ei põletata seda, vaid . Seega jõuab plast loodusesse.

Microplastics end up in the sewage sludge from the treated water. In Estonia, it is not incinerated but used in landscaping and agriculture. Thus, plastic enters nature.

Heinlaan ja tema meeskond , et määrata reoveesettides olevat mikroplasti ja muid aineid. Nad proovivad leida viise, kuidas mikroplasti hulka vähendada.

Plastic can break down into smaller particles. Plastic contains many different substances. Their impact on nature and health is still unknown.

Mikroplasti võib leida ka . Seda on raske täielikult vältida. Kuigi põllumajanduses kasutatavad plastiosakesed ei mõjuta toidu ohutust, tuleb .

Microplastics can also be found in house dust and city streets. It is difficult to completely avoid it. Although the plastic particles used in agriculture do not affect food safety, the accumulation of microplastics in the soil needs to be limited.
