摘要

The Malaria National Service built a factory of organoclorine pesticides used in public health campaigns (HCH and DDT) between 1950 and 1965, at Cidade dos Meninos, in the municipal district of Duque de Caxias/RJ to control the dissemination of endemic rural diseases. After a media outcry, in 1989, FEEMA investigated and found out that after the factory closure piles of residues were left behind causing the contamination of the soils. Analyses of foliar tissues and soil were conducted in two stands of Eucalyptus (Eucalyptus grandis e Corymbia citriodora (Hook.) K.D. Hill & L.A.S. Jhonson), with the objective of evaluating the potential of the species as phytoremediator of contaminated soils by organochlorines pesticides. A composite soil sample and five samples of leaves were collected in each one of the studied places. Three leaf samples from C. citriodora and two from E. grandis were analized for pesticides organochlorines by gas chromatography. Both species grew on the same conditions, with average heights of 9,1 e 16,8 m and average diameters of 7,8 and 15,95 cm for E. grandis and C. citriodora, respectively. The average height and diameter of C. citriodora were similar to those found for other stands in the Atlantic forest region while the E. grandis was a little bellow those averages. The presence of organochlorine pesticides was detected in the leaves at low concentrations but the concentrations in the soils were high, being greater in the E. grandis plantation. These results were compared to previous analyses and suggested that the species can function as phytoremediators especially the C. citriodora.

Hill＆L.A.S. Jhonson）的目的是通过有机氯杀虫剂评估物种作为植物植物植物的植物症的潜力。在每个研究的地方收集复合土壤样品和五个叶样品。通过气相色谱法分析来自C.Citriodora的三个叶子样品和来自E. Grandis的两种。这两种物种在相同的条件下增长，平均高度为9,1e12m，平均直径为7,8和15,95厘米，分别为Grandis和C.Citridora。 CITRIDORA的平均身高和直径与在大西洋森林地区的其他代表中发现的人的平均身高和直径相似，而E. Grandis是一点轰鸣声。在低浓度下在叶片中检测有机氯杀虫剂的存在，但是土壤中的浓度高，在E. Grandis种植园中更大。将这些结果与先前的分析进行了比较，并表明物种可以用作植物模型剂，尤其是C.Citriodora。
