- nutrient concentration for terrestrial system (nitrogen,phosphorus and potassium);
- growth of plants and algae;
- physical factors such as temperature;
- effect of pesticides;
- frequency of fertilizer and pesticide application;
- water added (drinking water, eutrophic water and water that has passed through a biological purification);
- heavy ions transferred from pesticides and from water that has eutrophication to products (vegetables) i.e. the quality of the vegetables compared to their concentration of heavy ions – copper (Cu), lead (Pb), cobalt (Co), cadmium (Cd) and nickel (Ni).
Various aspects of the terrestrial and aquatic systems will be monitored by SEMEP team such as:
- percent germination;
- temperature of the room;
- plant height
- water temperature
- nutrients in water
- leaf size
- the growth of algae
Plants used: sunflower (Helianthus annuus) and mung beans (Vigna radiata).
Aquatic plant: wild celery/ water-celery/ tape grass (Vallisneria americana).
