Joint effects of heavy metal binary mixtures on seed germination, root and shoot growth, bacterial bioluminescence, and gene mutation

Toxic Effects of Binary Mixtures of Heavy Metals on the Growth and P Removal Efficiencies of Alcaligenes sp.

“…생물학적 인 제거 공정은 세포 내에 다중 인산염의 형태로 다량의 인을 저장할 수 있는 것으로 알려진 인염 축적균 (Phosphorus Accumulating Organisms, PAOs) (Sedlak, 1991;Zuthi et al, 2008)에 혐기 조건과 호기조건을 교차시 킴으로써 인의 과잉흡수(Luxury uptake)를 유발하여 폐수 중 인을 제거하는 방법이다 (Levin and Sharpiro, 1965;Khoshmanesh et al, 2002). 현재, 인 제거를 위해 제시된 방법 중 가장 널리 인정받고 있는 모델은 Comeau-Wentzel 모델 (Comeau et al, 1987;Wentzel, 1989 (Yilmas, 2003), 중금속으로 인한 환경오염은 단일 중 금속이 아닌 여러 종류의 중금속 혼합에 의한 경우가 대부분 이며 Kong, 2013), 이에 대한 연구는 부족 한 실정이다. 이러한 한계를 극복하기 위해 최근에는 두 종류 이상의 중금속이 혼재시 일어나는 효과에 대한 연구가 진행 되고 있다 (Liu et al, 2007;Xu et al, 2011).…”

Germination of Bouteloua dactyloides and Cynodon dactylon in a Multi-Polluted Soil

“…Other metals like Hg, Pb, and Cd have never been shown to be essential for organism development and are toxic at low concentrations [2]. Environment pollution with heavy metals by increased industrialization and geochemical activities is a major environmental and human health problem [3] due to these metals' non-biodegradability and high toxicity [4].…”

“…Seed germination studies are requisite groundwork to determine if plants are suitable for growth in polluted soils for phytoremediation applications [8]. Unfortunately, predicting the response of organisms simultaneously exposed to more than one PTE is a difficult task in environmental toxicology [4].…”

Effects Research of Environmental Hormone BPA and PAEs on the Expression of HSP70-9 Gene in Spinacia oleracea

“…Current researchers who study EHs impact on organisms continue to increase, and have mainly focused on the influence of heavy metals on aquatic animals and plants [9][10][11][12], pesticides on insects [11], and EHs on organism genotoxicity [5]. The plasticizers, BPA for clear plastics and PAEs in hard plastics, have some estrogenic activity and anti-androgenic activity [4].…”
