Arak Aluminium Company

The first Producer of Aluminium in Iran, is Located at 5 Th km of Arak – Tehran Rd in Central Province, Iran.. The products of the firm are produced according to the international standards and the minimum purity degree of Aluminium is 99.70 % Iralco is the member of 'L.M.E. Products include aluminum billets, ingots, T-bars, and slabs.

There are many green spaces around this factory. Green space included lands that were partly or completely covered with grass, trees, shrubs. It found that urban green spaces provide significant health benefits by filtering harmful pollutants from the air and providing cooling effects during extreme heat. Various species of trees in different ages covered most of green space; trees which have a much greater surface area could reduce air pollution effectively, also lead to climate change.

our study reveals that urban trees are a significant element to reduce air pollution, we determined the Al concentration in leaves of different trees collected from parts of green space. The concentration of this metal was considerable in the following species:

Robinia pseudoacacia L

Common name: black locust, false acacia

Habitat: Dry, sandy and rocky habitats; scrub and woodland margins and roadsides; widely cultivated as an ornamental tree in streets and parks.

Leaves: The leaves are pinnate (divided into a central axis bearing leaflets) with 3–11 pairs of oval leaflets and one extra terminal leaflet. At maturity the leaflets are almost hairless.

Flowers: The scented flowers are 15–20 mm long. The calyx (outer whorl of floral organs) is reddish-purple, and the petals are white (the standard petal having a basal yellow blotch). The stalked flowers are clustered into showy, hanging racemes.

Fruits: The fruits are linear-oblong, hairless pods, with the upper suture (margin) slightly winged, and there are 4–10 seeds per pod.

Al status: Al is concentrated particularly in the bark. Seeds had lowest levels among different plant parts and tissues.

Fraxinus excelsior

It is a large deciduous tree growing to 12–18 m (39–59 ft) (exceptionally to 43 m or 141 ft) tall with a trunk up to 2 m (6.6 ft) (exceptionally to 3.5 m or 11 ft) diameter, with a tall, narrow crown.[1] Ash occurs on a wide range of soil types. The bark is smooth and pale grey on young trees, becoming thick and vertically fissured on old trees. The shoots are stout, greenish-grey, with jet black buds. The leaves are opposite, 20–35 cm (7.9–13.8 in) long, pinnately compound, with 7-13 leaflets with coarsely serrated margins, elliptic to narrowly elliptic, 3–12 cm (1.2–4.7 in) long and 0.8–3 cm (0.31–1.18 in) broad and sessile on the leaf rachis. The fruit is a samara 2.5–4.5 cm (0.98–1.77 in) long and 5–8 mm (0.20–0.31 in) broad, often hanging in bunches through the winter.

Al status: It was at high level in tree branches and then in leaves. The level was at second stage of top of plant list.

 

cercis siliquastrum

Cercis siliquastrum is a deciduous Tree growing to 12 m (39ft) by 10 m (32ft) at a medium rate. Suitable for: light (sandy), medium (loamy) and heavy (clay) soils, prefers well-drained soil and can grow in nutritionally poor soil. Suitable pH: acid, neutral and basic (alkaline) soils and can grow in very alkaline soils. avoid hot, exposed and windy sites.
It can grow in semi-shade (light woodland) or no shade. It prefers dry or moist soil and can tolerate drought. The flowers are quickly followed by the foliage, bright green and fresh, developing into rounded heart shape leaves attractive in their own right. In Autumn the foliage turns yellow but the feature of Cercis in this season are the clusters of reddish purple flattened seed pods which hang from the branches.

Al status:    This plant had the lowest Al levels among all evaluated trees. In addition Al was lower than accepted standard Al concentration in plants.
