摘要

由于缺乏精确的基线浓度数据,准确分析和监测全球土壤环境质量具有挑战性。哥伦比亚是一个几乎没有基线数据的国家。本研究的重点是Llanero山前高度风化的土壤(极度潮湿的赤道环境)。评估了基准钒(V)浓度,并检查了农业用地可能产生的影响。结果显示,不同土地利用方式的V浓度存在明显差异。自然环境土壤中V含量为5.8 ~ 76.7 mg kg - 1,平均为31.5 mg kg - 1;农业土壤中V含量为20.7 ~ 88.6 mg kg - 1,平均为51.8 mg kg - 1。总体平均值为41.7 mg kg - 1,范围为5.8 ~ 88.6 mg kg - 1,分布范围较广。V浓度与世界平均值比较,与其他地区相比在正常范围内。V的计算参考值(RV)为38.4 mg kg−1。基于污染因子,全区污染程度为中度(1.1)。用I-geo(- 0.6)分析时未检测到污染。这些结果清楚地表明,V在研究区耕地土壤中具有中度污染,但不构成生态风险。V浓度与所研究的岩性和成土因素之间没有简单的关系。这项工作包含有价值的信息,不仅为立法目的,而且为土壤质量的房车在高湿度的赤道气候。

Assessment of Vanadium Content in Soils Under Equatorial Climate

It is challenging to accurately analyze and monitor the environmental quality of soils globally because data on precise baseline concentrations are lacking. Colombia is a country where baseline data is practically missing. This study focused on the highly weathered soils of the Piedmont Llanero (hyperhumid equatorial environment). The baseline vanadium (V) concentration was assessed and the possible influence of agricultural land use was examined. The results showed clear variability in V concentrations across land uses. The V content in soils in the natural environment was 5.8–76.7 mg kg−1 with a mean of 31.5 mg kg−1 and in agricultural soils was 20.7–88.6 mg kg−1 with a mean of 51.8 mg kg−1. The overall average was 41.7 mg kg−1 with a range of 5.8–88.6 mg kg−1, which are widely scattered values. The V concentration was compared to the world average values and was within normal ranges versus other areas. The calculated reference value (RV) for V was 38.4 mg kg−1. Based on the contamination factor, contamination was moderate (1.1) in the whole area. No contamination was detected when analyzed with I-geo (−0.6). These findings clearly suggest that V was moderately contaminating in cultivated soils, but posed no ecological risks in the study area. No simple relation was found between V concentrations and investigated litho- and pedogenic factors. This work contains valuable information for not only legislative purposes but also for soil quality RVs in a hyperhumid equatorial climate.
