Chemical response of the lichens Parmotrema austrosinense and P. conferendum transplanted to urban and non-polluted environments

Thalli of the lichens Parmotrema austrosinense (Zahlbr.) Hale and P. conferendum Hale were taken from a non-polluted area and transplanted within this area, and to a downtown site in Cordoba, Argentina. Pigments, malondialdehyde, hydroperoxy-conjugated dienes and sulphur were measured after various...

Pigments, malondialdehyde, hydroperoxy-conjugated dienes and sulphur were measured after various exposure periods.
