The Toxicity of Selected Trace Metals to Lecane inermis Rotifers Isolated from Activated Sludge
The aim of the study was to assess the toxicity of a range of trace metals to the rotifer Lecane inermis, a species tested as a potential biological tool to control activated sludge bulking caused by overgrowth of filamentous bacteria in wastewater treatment plants. LC50 values (concentration lethal to 50 % of individuals, mg dm(-3)) were ranked in the following order: Cu < Al < Fe < Zn < Sn < ...
متن کاملAdsorption and toxicity of heavy metals on activated sludge
The adsorption of Cu, Cd, Ni, Zn, and Cr from synthetic solutions on powdered activated carbon (PAC), activated sludge, and dried sludge were investigated under laboratory conditions to assess its ability to remove heavy metals. The adsorption efficiency increased rapidly within the first 30 min and then slowed down as it approached a steady state after 5 h of contact time. The results showed t...
متن کاملAcute toxicity of lead, chromium, and other heavy metals to ciliates from activated sludge plants.
Numerous papers have been published which deal with the occurrence of heavy metals in the various components of freshwater ecosystems (Radwan et al. 1990; Scanferlato and Cairns 1990; Hintelmann et al. 1993) and sewage treatment systems (Yetis and Gokcay 1989; Cimino and Caristi 1990; Dilek and Yetis 1992; Melcer et al. 1992; Moriyama et al. 1992). However, only a few papers refer to the presen...
متن کاملSeasonal changes in the body size of two rotifer species living in activated sludge follow the Temperature-Size Rule
Temperature-Size Rule (TSR) is a phenotypic body size response of ectotherms to changing temperature. It is known from the laboratory studies, but seasonal patterns in the field were not studied so far. We examined the body size changes in time of rotifers inhabiting activated sludge. We hypothesize that temperature is the most influencing parameter in sludge environment, leading sludge rotifer...
متن کاملfrom linguistics to literature: a linguistic approach to the study of linguistic deviations in the turkish divan of shahriar
chapter i provides an overview of structural linguistics and touches upon the saussurean dichotomies with the final goal of exploring their relevance to the stylistic studies of literature. to provide evidence for the singificance of the study, chapter ii deals with the controversial issue of linguistics and literature, and presents opposing views which, at the same time, have been central to t...
