Abstract
This study evaluated the physicochemical properties and the concentrations of metal(oid)s in soils with approximately 5, 20 and 40 years of sugarcane cultivation from a locality in Quintana Roo, Mexico. The results showed the metal(oid) concentration order Fe > Cr > V > Pb > Co > Cu > As, with a gradual increase in their concentrations up to 33,834, 76, 67, 59, 32, 22 and 14 mg kg-1, respectively, after 40 years of sugarcane cultivation. The contamination factor indicated considerable contamination for Co, Cr, Pb and V and very high contamination for Fe in soils subjected to 40 years of sugarcane cultivation. The pollution load index revealed medium pollution in soils with 5 and 20 years of sugarcane cultivation, and moderate pollution in soils with 40 years. The organic matter, organic carbon and total nitrogen contents decreased significantly as the length of sugarcane cultivation increased. These results highlight the need to implement measures for proper agricultural management.
本研究评估了墨西哥金塔纳罗奥地区甘蔗种植约5年、20年和40年土壤中的物理化学性质和金属(类)s浓度。结果表明:经过40年的甘蔗栽培,金属(类)浓度依次为Fe > Cr > V > Pb > Co > Cu > As,其浓度依次递增,分别达到33,834、76、67、59、32、22和14 mg kg-1。甘蔗栽培40年土壤中Co、Cr、Pb、V的污染程度较高,Fe的污染程度很高。甘蔗种植5年和20年土壤污染负荷指数为中度污染,种植40年土壤污染负荷指数为中度污染。随着甘蔗栽培年限的增加,土壤有机质、有机碳和全氮含量显著降低。这些结果突出了实施适当农业管理措施的必要性。
