PHYTOREMEDIATION Using Plants to Clean Up the Soil

Phytoremediation of Cd

・As-Hyperaccumulator ・Tropical~Subtropical Plant ・ High  Production Efficiency

Pteris vittata L. ( Chinese brake fern )

Phytoremediation of As Arabidopsis halleri ssp. gemmifera

Transplanting(Sep.)

Harvesting Pre-harvest (May)

This technology reduces Cd levels in farmland helping ensure food safety.

Fig. Cd concentration in soil is reduced to 55% by phytoremediation in one cropping season.

<Field Trials>

Investigation of contaminated soil distribution

Treatability Examination  ・Analysis of chemical form of As  ・Pot cultivation test Estimate the efficiency of As removal

Apply Phytoremediation The usual method

1. Plan

2. Culture

Land grading

Transplanting(May – Jun.)

Cultivation ( Watering, Weeding, Fertilizing )

3. Removal

Harvesting Fern(Nov.)

Harvest disposal

Assessment of As removal Next year’s planning

・Cd-Hyperaccumulator ・Brassicaceae Plant ・Annual Herb ・Possible to Rotate with Other Plants for Phytoremediation

Raising of seedlings
