“…Each of these approaches and experimental set-ups has their own advantages and limitations. However, scientific knowledge acquired in the above model experiments in the last three decades has advanced the field of phytoremediation which is a proven technology today and it is accepted by regulatory agencies and scientific community globally ( Deligiannis et al 2009, Gonzalez-chavez et al 2015, Goyal et al 2014, Huagang et al 2011, Jumat et al 2010, Kiran & Prasad 2016, 2017, Kumar & Prasad 2015, Ogunniyi 2006, Pal et al 2013, Pandey 2013, Romeiro et al 2006, Sailaja 2008, Sharma & Dubey 2005, Tang et al 2015,Wu et al 2012, Yi et al 2014 …”

“…Thus it is considered to be a potential phytoremediator (Bauddh and Singh, 2012). However, great differences in Cd accumulation have been observed among various castor cultivars (Huang et al, 2011). The application of castor cultivars capable of high Cd accumulation may be an effective way to perform phytoremediation in Cd-polluted soil.…”

“…Cadmium (Cd) is an environmental toxicant (Thévenod, 2009) and one of the main pollutants in soil (Huang et al, 2011). Cadmium is not degraded in the environment and is easily transferred from the soil to the human body via the food chain, thus endangering human health (Jarup, 2003).…”

a b s t r a c tThe aims of this study were: (1) the study of cadmium (Cd) accumulation and toxicity in different castor cultivars (Ricinus communis L.); (2) to investigate changes in antioxidant enzymatic activities and the subcellular distribution of Cd in young and old leaves from two different castor cultivars, after exposure to two different Cd concentrations, and explore the underlying mechanism of Cd detoxification focusing on antioxidant enzymes and subcellular compartmentalization. The Cd concentration, toxicity, and subcellular distribution, as well as superoxide dismutase (SOD), catalase (CAT), and peroxidase (POD) activities were measured in Zibo-3 and Zibo-9 cultivars after exposure to two different concentrations of Cd (2 mg/L and 5 mg/L) for 10 days. This research revealed Cd accumulation characteristics in castor are root4 stem4 young leaf 4old leaf. Castor tolerance was Cd dose exposure and the cultivars themselves dependent. Investigation of subcellular Cd partitioning showed that Cd accumulated mainly in the heat stable protein (HSP) and cellular debris fractions, followed by the Cd rich granule (MRG), heat denatured protein (HDP), and organelle fractions. With increasing Cd concentration in nutrient solution, the decreased detoxified fractions (BDM) and the increased Cd-sensitive fractions (MSF) in young leaves may indicate the increased Cd toxicity in castor cultivars. The BDM-Cd fractions or MSF-Cd in old leaves may be linked with Cd tolerance of different cultivars of castor. The antioxidant enzymes that govern Cd detoxification were not found to be active in leaves. Taken together, these results indicate Cd tolerance and toxicity in castor can be explained by subcellular partitioning.Crown

“…Adotar estratégias destinadas a aumentar a eficácia da fitorremediação tem sido amplamente estudado por diversos pesquisadores (CONTRERAS-RAMOS et al, 2008;DELGADO-MORENO & PEÑA, 2009;HUANG et al, 2011;ROMEH, 2015). A mobilidade e biodisponibilidade dos compostos xenobióticos no solo pode ser controlada por alterações orgânica ou inorgânica, sendo que a primeira apresenta vantagens mais eficazes sobre a segunda.…”

RESUMOA contaminação do ambiente agrícola tornou-se um grave problema global. O uso indiscriminado de pesticidas tem provocado diversos problemas à saúde humana, toxicidade a organismos alvo e não alvo, além de alterar a qualidade do ar, água e solo. Em 2008, o Brasil se tornou o maior consumidor mundial de pesticidas e por isso cresce o interesse em investigar estratégias de remediação in situ desses compostos. Neste sentido o objetivo desta pesquisa foi discutir sobre as diferentes estratégias de fitorremediação e vermirremediação de solos contaminados com pesticidas e as respectivas vantagens e limitações de cada uma dessas biotecnologias. Observou-se que as biotecnologias apresentadas neste trabalho apresentam vantagens econômicas e ambientais em comparação com os métodos físicos e químicos, porém apresentam limitações que precisam ser superadas através de pesquisa científica e ensaios em escala de laboratório, piloto e campo. Muitos trabalhos têm sido desenvolvidos na área de biotecnologias de remediação de solos contaminados por pesticidas, entretanto a maioria ocorre em condições de clima temperado. O Brasil precisa explorar mais essas biotecnologias uma vez que dispõe de elevado potencial por possuir condições climáticas e biodiversidade mais favorável em comparação com regiões de clima temperado. PALAVRAS-CHAVE: Contaminantes orgânicos, fitorremediação, vermirremediação. REMEDIATION BIOTECHNOLOGIES FOR CONTAMINATED SOIL WITH AGROCHEMICALSABSTRACT The contamination of the agricultural environment has become a major global problem. The indiscriminate use of pesticides has caused several problems to human health, toxicity to target organisms and non-target, and change the quality of air, water and soil. In 2008, Brazil became the world's largest consumer of pesticides and therefore growing interest in investigating remediation strategies in situ these compounds. In this sense, the objective of this research is to discuss the different strategies of phytoremediation and vermiremediation of soils contaminated with AGRARIAN ACADEMY, Centro Científico Conhecer -Goiânia, v.3, n.05; p.2016 28 pesticides and their advantages and limitations of each of these biotechnologies. It was observed that biotechnologies presented in this work have economic and environmental advantages compared to the physical and chemical methods, but have limitations that must be overcome through scientific research and conduct testing in laboratory scale, pilot scale and field scale. Many studies have been developed in the area contaminated by pesticides soil remediation technologies, though most occur in temperate conditions. Brazil needs to further explore these biotechnologies since it has high potential for having climatic conditions and more favorable biodiversity compared with temperate regions. KEYWORDS: Phytoremediation, vermiremediation, organic contaminants. INTRODUÇÃOAs principais fontes de contaminação do solo e água provém de rejeitos urbanos e industriais, agroquímicos e/ou vazamentos acidentais de compostos xenobióticos. Q...
