Abstract:
A field survey was conducted to search for Pb accumulation in fern species
at Bo Ngam Pb mine, Kanchanaburi Province, Thailand. Eleven fern species:
Angiopteris evecta, Dicranopteris linearis, Lygodium flexuosum, Microlepia
herbacea, Pteris venusta, Pteris vittata, Sphenomeris chinensis, Thelypteris sp.,
Thelypteris lakhimpurensis, Thelypteris interrupta, and Tectaria polymorpha
accumulated Pb in the range of 23.3-295.6 mg kg-1 in the aboveground parts of the
plants. Hydroponic, pot, and field trial experiments were carried out to investigate
Pb-accumulation ability in ferns: P. vittata and three ornamental species,
Pityrogramma calomelanos, Neophrolepis exaltata cv. Gracillimum, and N.
exaltata cv. Smirha. In hydroponic experiment, Pi. calomelanos accumulated the
highest concentration of Pb (root 14161.1 mg kg-1, frond 402.7 mg kg-1). The pot
study showed that P. vittata, Pi. calomelanos, and N. exaltata cv. Gracillimum
grew well when grown in Pb soil at 92900 mg kg-1. N. exaltata cv. Gracillimum
accumulated the highest Pb concentration in the frond (5074 mg kg-1) and P. vittata
accumulated the highest Pb concentration in the root (16257.5 mg kg-1). All fern
species exhibited TF values less than 1 in both hydroponic and pot experiments.
When P. vittata and Pi. calomelanos were grown at mine sites for 6 months, P.
vittata tolerated higher soil Pb (94584-101405 mg kg-1) and accumulated more Pb
in frond (4829.6 mg kg-1) and showed TF > 1 after 2 months of growth. These
results indicated that P. vittata can be potentially useful for phytoremediation of
Pb-contaminated soil. Furthermore, the structural and ultrastructural study for Pb
toxicity by TEM of P. vittata and Pi. calomelanos also showed ultrastructural
changes in chloroplasts and mitochondria such as distortion of thylakoid
membranes and accumulation of plastoglobuli in chloroplasts of mesophyll cells
which indicated a metal-induced enhancement of chloroplast senescence. The
swelling, reduction in number of cristae, and disintegration of mitochondrial
membrane in root and frond cells were observed which also indicated the toxicity
of Pb to these ferns.
