The mEI, Chromocult® enterococci, and m-Enterococcus culture-based methods used to assess water quality by the detection of Enterococcus spp. were first compared in terms of sensitivity using (1) 41 different type strains of Enterococcus spp. and (2) environmental colonies identified by 16S rRNA sequencing. Then, two specific-rtPCR ...

ABSTRACT BOS 100 was successfully implemented as part of a combined remedies strategy to treat elevated levels of Trichloroethylene in a shallow fine grained aquifer at a former large industrial facility. CHALLENGES A large industrial facility used vapor degreasing in the 1970s and 1980s that resulted in chlorinated volatile organic compound (CVOC) ...

Combined sewer overflow (CSO) structures are constructed to effectively discharge excess water during heavy rainfall, to protect the urban drainage system from hydraulic overload. Consequently, most CSO structures are not constructed according to basic hydraulic principles for ideal measurement weirs. It can, therefore, be a challenge to quantify the discharges from CSOs. Quantification of CSO ...

Normal ranges are some fraction of a reference distribution deemed to represent an expected condition (typically 95%). They are frequently used as the basis for generic criteria for monitoring programs designed to test whether a sample is outside of “normal”, as in reference condition approach studies. Normal ranges are also the basis for criteria for more classic environmental effects ...

Standard ecotoxicity tests are conducted under constant and favorable experimental conditions. In natural communities, however, the toxicity of chemicals may be influenced by abiotic and biotic environmental factors. Firstly, the authors examined the influence of temperature and total food concentration on the nature of the combined effects of copper (Cu) and the cyanobacterium Microcystis ...

Increasing activity of oil sands extraction and processing in northern Alberta is marked by ongoing controversy about the nature and extent of associated environmental impacts. Bitumen contains a mixture of toxic chemicals, including metals and residual polycyclic aromatic hydrocarbons (PAHs), whose release into the environment poses a distinct risk to the surrounding environment, plus ...

Environmental laboratories practice “applied analytical chemistry” by analyzing samples using a list of potential contaminants to determine how much, if any, of the contaminant is present. These contaminants, the methods used to analyze for them, and the maximum amount of contaminant allowed in the sample are defined by regulation. This paper provides an overview of ...

Cytogenetic testing is used for the diagnosis of many genetic disorders including congenital (prenatal and adult) and hematologic/oncologic disorders. Processing of these tests used to be labor-intensive with unpredictable test data. That’s why the Cytogenetic Laboratory at Mayo Clinic and Thermotron joined forces to increase the efficiency of cytogenetic test processing with the invention ...

Consistency of optimum chromosome spreading during harvest of cytogenetic specimens remains a major concern. We have tested the idea that a precise control of the drying rate (the time with which metaphase cells dry), as fixed cell suspension is placed on a slide or an in situ culture in last fixation, may be the answer. Amniocyte and lymphocyte cultures were allowed to dry at defined ...

Environmental factors are important in that they might interact with toxicants and could affect the concentration‐response relationship of the toxicants in the water environment. Microcystins (MCs) produced by algal blooming are natural toxins that exert severe impact on aquatic organisms. Despite the possibility of interaction effects between environmental factors and MCs, very few studies ...

Our investigation centered around the aim of whether and how two environmental factors could influence the toxicity of a pyrethroid to two representatives of an important group of soil organisms. The impacts of different temperatures (20°C and 26°C) and soil moisture levels (30%, 50% and 70% of the water holding capacity) were investigated in combination with the insecticide lambda‐cyhalothrin ...

The current European legislation requires that combined effects of the active substances (a.s.) and any substance of concern contained in biocidal products are taken into account in the environmental risk assessment. The hypothesis whether the consideration of a.s. together with all formulation additives that are labelled as presenting an environmental hazard is sufficient for a reliable ...

Rivers, lakes and the sea were the natural receivers of raw urban waste and storm waters for a long time but the low sustainability of such practice, the increase of population and a renewed environmental sensibility increased researcher interest in the analysis and mitigation of the impact of urban waters on receiving water bodies (RWB). In Europe, the integrated modelling of drainage systems ...

Ceriodaphnia dubia were tested to evaluate the acute and chronic interactive effects of diphenhydramine and sertraline. Observed effects were compared to two reference toxicity models, the concentration addition model and the independent action model. Results indicate that the two drugs exhibit additive toxicity in C. dubia. In some cases, individually sublethal concentrations of the chemicals ...
