Abstract

We characterized the spatial and seasonal distributions of different phosphorus fractions in surface sediments from the Furo of Muriá estuary by chemical fractionation. Five phosphorus species were successfully separated: phosphorus bound to Fe/Al oxyhydroxides (non-apatite inorganic phosphorus (NAIP) ranging from 164.54 to 280.32 μg g-1), phosphorus bound to calcium (apatite phosphorus (AP) ranging from 63.02 to 102.80 μg g-1), inorganic phosphorus (IP, ranging from 227.21 to 378.61 μg g-1), organic phosphorus (OP, ranging from 30.33 to 135.88 μg g-1) and total phosphorus (TP, ranging from 257.54 to 507.73 μg g-1), in which 88% of TP is constituted by IP. Statistical results showed that seasonality was not a major factor influencing phosphorus concentrations. Considering the classification of estuarine sediment conditions, we can conclude that the TP concentrations found in Furo of Muriá do not yet indicate the risk of environmental deterioration.

巴西帕尔州穆里伊富罗赤道亚马逊河口沉积物中的磷浓度
采用化学分馏法对穆里河口富罗表层沉积物中不同磷组分的空间和季节分布特征进行了研究。成功分离出5种磷:与Fe/Al氢氧化物结合的磷(非磷灰石无机磷(NAIP)范围为164.54 ~ 280.32 μg -1)、与钙结合的磷(磷灰石磷(AP)范围为63.02 ~ 102.80 μg -1)、无机磷(IP,范围为227.21 ~ 378.61 μg -1)、有机磷(OP,范围为30.33 ~ 135.88 μg -1)和总磷(TP,范围为257.54 ~ 507.73 μg -1),其中88%的TP由IP组成。统计结果表明,季节性不是影响磷浓度的主要因素。考虑到河口沉积物条件的分类,我们可以得出结论,muri Furo发现的TP浓度尚未表明环境恶化的风险。
