摘要

自 1822 年以来,缅甸曼德勒的 Amarapura 镇一直从事传统龙衣的纺织品染色和编织,20 世纪初从天然染料过渡到化学染料。由于曼德勒目前没有废水处理设施,染料废水与其他废水混合在居民住宅附近开挖的无衬里水渠中,然后排入当地的水渠和地下水中。由于当地人主要依靠挖井和管井来饮用、洗澡和做饭,这一行业对该地区居民的健康构成了重大危害。这项研究的目的是确定纺织染料中以前未知的成分,并确定和量化染料废水中主要离子和重金属的浓度,以及确定它们对当地地下水资源的影响。染色过程中每个阶段的粉末染料样本都根据用于制造这些彩色染料的重金属组合进行了特征描述。此外,还对地下水和地表水进行了采样。染料和水样的分析结果表明,大部分重金属都排入了地下水环境。纺织品染色是阿马拉普拉镇居民的主要污染源和健康隐患;然而,当地人并不容易将染色做法与他们的饮用水问题联系起来。这项研究提供了阿马拉普拉镇染色工业附近地下水成分的信息,有助于为进一步的监测策略提供依据,并向当地居民宣传接触重金属对健康造成的风险。

Textile dyes as a source of groundwater contamination in Mandalay, Myanmar

Textile dyes as a source of groundwater contamination in Mandalay, Myanmar

Textile dyeing and weaving of traditional longyi garments have traditionally occurred in the Amarapura township of Mandalay, Myanmar, since 1822, transitioning from natural to chemical dyes in the early 1900s. With no current wastewater treatment facilities in Mandalay, dye effluents mix with other wastewaters in unlined canals dug near people’s homes and discharge into the local canals and groundwater. Because locals rely heavily on dug and tube wells for drinking, bathing, and cooking, this industry poses a major health hazard to the people in this region. The objective of this study was to identify the previously unknown composition of the textile dyes, as well as identify and quantify the concentrations of major ions and heavy metals found in dye effluents, and determine their impact on the local groundwater resources. Powdered dye samples from each stage of the dyeing process were characterized by the combination of heavy metals used to create these color dyes. Groundwater and surface water were also sampled. Results of analysis of the dye and water samples indicated that most of the heavy metals discharge into the groundwater environment. Textile dyeing is a major source of pollution and a health hazard to the residents of Amarapura township; however, the locals are not readily connecting dye practices to the issues with their drinking water. This study provides information on groundwater composition near dyeing industries in Amarapura township that may help inform further monitoring strategies and communicate the health risks of exposure to heavy metals for local people.

期刊介绍: Hydrogeology Journal was founded in 1992 to foster understanding of hydrogeology; to describe worldwide progress in hydrogeology; and to provide an accessible forum for scientists, researchers, engineers, and practitioners in developing and industrialized countries. Since then, the journal has earned a large worldwide readership. Its peer-reviewed research articles integrate subsurface hydrology and geology with supporting disciplines: geochemistry, geophysics, geomorphology, geobiology, surface-water hydrology, tectonics, numerical modeling, economics, and sociology.
