| heavy metal accumulation and tolerance in plants from mine tailings of the semiarid cartagena-la unión mining district (se spain). | mine tailings are a characteristic of landscapes where mineral extraction has occurred. these tailings usually contain high heavy metal concentrations and have low fertility. in arid and semiarid zones, erosion may be an additional problem. the removal of these tailings is often impractical due to their large volumes. therefore, a need exists to develop in situ low cost technologies to effect surface stabilization. the use of vegetation can be an attractive option, since there are some native pl ... | 2006 | 16499952 |
| growth of lygeum spartum in acid mine tailings: response of plants developed from seedlings, rhizomes and at field conditions. | lygeum spartum is a native species in semiarid mediterranean areas that grows spontaneously on acid mine tailings. we aimed to study the suitability of this plant for phytostabilization. l. spartum was grown from both seeds and rhizomes in acid mine tailings with various fertilizer and lime treatments. untreated soils had a solution ph of 2.9 with high concentrations of dissolved salts (electrical conductivity 25 ds m(-1)) and zn (3100 mg l(-1)). plants grown on untreated soil had high shoot met ... | 2007 | 17011091 |
| fungal root endophytes from natural vegetation in mediterranean environments with special reference to fusarium spp. | surveys (in 2002 and 2003) were performed for fungal endophytes in roots of 24 plant species growing at 12 sites (coastal and inland soils, both sandy soils and salt marshes) under either water or salt stress in the alicante province (southeast spain). all plant species examined were colonized by endophytic fungi. a total of 1830 fungal isolates were obtained and identified by morphological and molecular [internal transcribed spacer (its) and translation elongation factor-1alpha gene region (tef ... | 2008 | 18248439 |
| the cartagena-la unión mining district (se spain): a review of environmental problems and emerging phytoremediation solutions after fifteen years research. | after mining in the cartagena-la unión mining district (se spain) was discontinued in 1992, various studies have shown that large amounts of toxic metals continue to be transferred with the spread of unstabilized mining wastes to the nearby ecosystems. local creeks seem to be important pathways carrying eroded materials from the headwaters to the nearby coastal areas of the mediterranean sea. studies have shown the presence of high metal concentrations in the sediments of riverbeds and in river ... | 2010 | 20390210 |
