Abstract

It was stated that the use of urban wastewater in food production in the 1970s and 1980s may lead to the development of alternative farming systems in the future. Fish fed with wastewater are grown in Asian countries. However, due to the mixing of domestic wastewater with industrial wastewater, many toxic micro-polluting wastewaters affect fish farming even more. The objectives of this study were to investigate the suitability of fish for human food consumption in terms of metals, to provide a basis for the development of a standard on the concentration of heavy metals in reclaimed water used for fish aquaculture, and to search the possibilities of technical improvement of the system in terms of more efficient wastewater treatment. This study will be useful in terms of precautions and disadvantages that can be taken against food shortages that may be experienced with the effect of climate change.
废水饲养鱼类体内微量金属生物积累的研究
有人指出,20世纪70年代和80年代在粮食生产中使用城市废水可能导致未来发展替代农业系统。亚洲国家养殖用废水喂养的鱼。然而,由于生活废水与工业废水的混合,许多有毒微污染废水对养鱼的影响更大。本研究的目的是调查鱼类在金属方面是否适合人类食用,为制定用于鱼类养殖的再生水中重金属浓度标准提供依据,并在更有效的废水处理方面探索技术改进系统的可能性。这项研究将有助于预防气候变化可能导致的粮食短缺。
