- From phyto to agromining: past, present, and future scopePublication . Novo, Luís A. B.; Castro, Paula M. L.; Alvarenga, Paula; Silva, Eduardo Ferreira daThe accumulation of valuable metals in plants has fascinated scientists ever since the 1700 s (Chaptal 1790; Malte-Brun 1824).
- Plant growth–promoting rhizobacteria-assisted phytoremediation of mine soilsPublication . Novo, Luís A. B.; Castro, Paula M. L.; Alvarenga, Paula; Silva, Eduardo F. daThe ever growing buildup of mine waste across the planet has become a global concern. Mine spoils often endanger surrounding ecosystems because toxic metals migrate through air, water, and soil, and ultimately enter the food chain. Yet, conventional techniques are usually impracticable because of the large amounts of mine waste, their cost and frequent hazardous side effects. Phytoremediation, a plant-based technique that allows immobilizing and/or extracting pollutants has shown promising results in the reclamation of mine tailings. Nevertheless, the need to enhance the efficiency of phytoremediation has prompted the adoption of auxiliary strategies such as the use of plant growth-promoting rhizobacteria (PGPR). PGPR are known to bestow a wide variety of beneficial effects such as increased growth, improved immunity, and the modification of metal phytoavailability in the rhizosphere, to name a few. In this chapter, we review the impact of PGPR on phytoremediation of mine soils to date and discuss future directions.
- Recent advances in phytoremediation of soil contaminated by industrial waste: a road map to a safer environmentPublication . Bernardino, Cassiano A. R.; Mahler, Claudio F.; Alvarenga, Paula; Castro, Paula M. L.; Silva, Eduardo Ferreira da; Novo, Luís A. B.The advent of the industrial revolution has boosted human and technological development, but at a price. Contaminants have been increasingly accumulating across wider areas scattered around the world, making pollution a major planetary issue. Among these pollutants, those related to industrial waste are perhaps the most threatening due to their broad variety and capacity to migrate through the air, water, and soil, enter the food chain, and cause a deleterious impact on life and the environment. Finding solutions to deter industrial pollution has thus become the need of the hour. However, conventional techniques have often proven unworkable due to their cost and harmful collateral effects to the environment. In this light, a plant-based technique with the capacity to stabilize, extract, and/or degrade pollutants known as phytoremediation, has emerged as a promising alternative due to its inexpensiveness and environment-friendly character. Here, we review the latest advances on phytoremediation of sites afflicted by industrial pollution and outline the future scope of this green technique.
