The study was performed to examine the occurrence of endocrine disrupting chemicals (EDCs), including four steroid estrogens, one plasticizer, and three preservatives in the Mahakam River, Indonesia. The physicochemical analysis of river water and sediment quality parameters were determined as well as the concentration of EDCs. The range of values for pH, total dissolved solids (TDS), dissolved oxygen (DO), biochemical oxygen demand (BOD), total suspended solids (TSS), nitrate, ammonium, phosphate, and oil/grease in river water and sediment were higher than recommended limits prescribed by the World Health Organization's Guidelines for Drinking-water Quality (GDWQ). Bisphenol A (BPA) was the most widely found EDC with the highest concentration level at 652 ng/L (mean 134 ng/L) in the river water and ranged from ND (not detected) to 952 ng/L (mean 275 ng/L) in the sediment. Correlation analysis to investigate the relationship between the EDCs' concentrations in water and sediment also revealed a significant correlation (R2 = 0.93) between the EDCs' concentrations. High concentrations of EDCs are found in urban and residential areas because these compounds are commonly found in both human and animal bodies, resulting in the disposal of EDCs into canals and rivers in urban and suburban areas, as well as livestock manure and waste that is generated from intensive livestock farming around the suburban area.

Mahakam河的河水和沉积物中会发生破坏内分泌的化学物质(EDC)。

进行该研究的目的是检查印度尼西亚马哈卡姆河内分泌干扰化学物质(EDC)的发生情况,包括四种类固醇雌激素,一种增塑剂和三种防腐剂。确定了河流水和沉积物质量参数的物理化学分析以及EDC的浓度。pH,总溶解固体(TDS),溶解氧(DO),生化需氧量(BOD),总悬浮固体(TSS),硝酸盐,铵,磷酸盐和河水和沉积物中油/脂的值范围分别为高于世界卫生组织《饮用水水质准则》(GDWQ)规定的建议限值。双酚A(BPA)是最广泛发现的EDC,在河水中浓度最高,为652 ng / L(平均134 ng / L),范围从ND(未检测到)到952 ng / L(平均275 ng / L)。 L)在沉积物中。相关性分析研究了EDC在水和沉积物中的浓度之间的关系,还发现EDC的浓度之间存在显着的相关性(R2 = 0.93)。在城市和居民区发现高浓度的EDC,因为这些化合物普遍存在于人和动物体内,导致EDC进入城市和郊区的运河和河流,以及产生的牲畜粪便和废物来自郊区的集约化畜牧业。相关性分析研究了EDC在水和沉积物中的浓度之间的关系,还发现EDC的浓度之间存在显着的相关性(R2 = 0.93)。在城市和居民区发现高浓度的EDC,因为这些化合物普遍存在于人和动物体内,导致EDC进入城市和郊区的运河和河流,以及产生的牲畜粪便和废物来自郊区的集约化畜牧业。相关性分析研究了EDC在水和沉积物中的浓度之间的关系,还发现EDC的浓度之间存在显着的相关性(R2 = 0.93)。在城市和居民区发现高浓度的EDC,因为这些化合物普遍存在于人和动物体内,导致EDC进入城市和郊区的运河和河流,以及产生的牲畜粪便和废物来自郊区的集约化畜牧业。
