“…This is not consistent with the results of the study conducted by Ostaszewska et al [ 33 ], who demonstrated that CuNPs were more toxic than AgNPs. This was confirmed by the results of the study by Shahbazzadeh et al [ 15 ], who investigated the effect of AgNPs on rainbow trout. However, the difference between these studies and ours is the different methods used for the metal application, which could have produced the difference in results.…”

“…According to Shahbazzadeh [ 15 ], nanosilver (as Nanocid) at low concentrations is not toxic to rainbow trout; therefore, it is worth considering the possibility of its application as a substitute for other agents, e.g., the abovementioned malachite green, chloramine T, or copper sulfate. In turn, in a study on rainbow trout hatchability, Soltani et al [ 16 ] drew attention to the possibility of counteracting saprolegniosis using a preparation with silver nanoparticles (AgNPs), where the authors obtained promising results using doses of 0.5–4 mg/L.…”

Nanotechnology is a rapidly growing field of science, and an increasing number of nanoproducts, including nanometals, can be found on the market. Various nanometals and the products that are manufactured based on them can help to fight bacteria and fungi, but they can also penetrate organisms and accumulate in them. This study aimed to compare the effects of two metals, silver (Ag) and copper (Cu), with known antibacterial and fungicidal properties in their ionic (AgNO3, CuSO4·5H2O) and nanoparticle (AgNPs, CuNPs) forms on rainbow trout eggs and fry. Concentrations of metals ranging from 0 to 16 mg/L were used during egg swelling for 2 h. The swelling of eggs in Cu solutions resulted in an increase in Cu content in the eggs (just like in the case of Ag); however, the changes in fry were not significant in the case of both Ag and Cu. The concentrations of these metals in eggs was greatly affected by the applied form of Ag and Cu. Because CuNPs penetrated the embryo in fish eggs at lower concentrations compared to AgNPs, it would be worth considering them for antibacterial applications during egg incubation.

“…The Pars Nano Nasb Company in Iran has been developing the technology of applying silver nanoparticles to impose the efficiency of reducing bacterial contamination in the production of chicken and other animals. Therefore, the nanosilver is used today more as a high disinfectant in poultry production farms in Iran (Shahbazzadeh et al 2009). Although many studies have been done to evaluate the impact of nanosilver in birds, the effects exerted by silver nanoparticles administration on the overall reproductive performances of avian species have not been fully studied, especially when the egg and meat of birds are the main protein sources for human.…”

Silver nanoparticles could prove to be a valuable alternative raw material for antibiotics and disinfectants as it is relatively free of adverse effects. Nanosilver is now been put to practical use in commonly used items, such as, clothes, electric home appliances, and electronic industry, but has not been widely applied in the medical or pharmacological fields. This study was designed to investigate the effects of nanosilver on egg quality traits in laying Japanese quail in completely randomized design with four treatments and six repetitions at 0, 4, 8 and 12 ppm of silver nanoparticle levels. Eggs collected daily and egg parameters, including egg weight, length, width; yolk weight and eggshell thickness were examined. The effect of the different silver nanoparticle levels was determined using the General Linear Model of SAS procedure, whilst differences between the groups were determined using least significant difference test. Results indicated that silver nanoparticles at all levels caused significantly reduce of yolk weight and hen-day egg production for each week than the control treatment (P \ 0.05), whilst silver nanoparticle had no significant effect on egg weight, egg length and width and eggshell thickness.

“…Steady-state (or static) ecotoxicology tests rely on a set concentration, for a specific period of time, often with no consideration of exposure variability (U.S. Environmental Protection Agency 2002). For example, a broad range of studies used static methods to expose aquatic organisms to a range of concentrations of a toxicant in order to determine LC50 values (Dede and Kaglo 2001;Shahbazzadeh et al 2009;Ramanujam and Dominic 2012;Rathnamma and Nagaraju 2013). However, these LC50 values do not accurately represent the response of an organism due to exposure in a natural system.…”

The Degree of Impairment of Foraging in Crayfish (Orconectes virilis) due to Insecticide Exposure is Dependent upon Turbulence Dispersion

As toxicants move into aquatic systems, the concentration at any point in space or time is heavily influenced by the flow dynamics. The dispersion of these chemicals creates a toxicant concentration that fluctuates widely in time and is highly dependent on the spatial heterogeneity of turbulence. Despite this knowledge on the movement of toxicants in natural systems, most ecotoxicological studies use static exposure paradigms that ignore the spatio-temporal dynamics of toxicants in aquatic systems. Although recent studies have begun to use pulsed paradigms in an attempt to mimic natural conditions, the heterogeneity of real concentrations in natural systems rarely is considered for use in these tests. Thus, understanding how organisms are impaired by naturally distributed toxicants is relatively unknown. The purpose of this experiment was to determine how turbulent dispersion of a toxicant negatively impacts a behavioral task and if altering the nature of turbulence will change the negative impact of the toxicant. Crayfish were exposed to a turbulent plume of carbaryl, an insecticide, under two different turbulent conditions and two different spatial conditions. Turbulence was altered by placing an obstruction within the flow which mimics a natural obstruction in lentic systems. Crayfish were exposed to sublethal concentrations of carbaryl for 48 h under these different dynamic conditions. After toxicant exposure, crayfish foraging ability was measured in a flow-through Y maze. We hypothesized that crayfish exposed to the toxicant under more turbulent conditions would exhibit more detrimental responses due to the increased variation in chemical fluctuations. The fine-scale chemical distribution of the toxicant and the three-dimensional velocity profile were characterized for each of the turbulent conditions and each of the spatial locations. Analyses of these data showed that changes in turbulence or spatial location created a unique exposure condition. Particularly, significant variations in the rise time, intermittency, and slope of toxicant pulses were quantified, whereas average concentration of the peaks remained constant across locations. Deficits in the foraging ability of crayfish exposed under these dynamic conditions paralleled the differences quantified in parameters of the turbulent toxicant plume. Given these results, the concept of toxicant exposure needs revision and needs to incorporate the more temporally based measures of toxicant dispersion. In addition, static and pulsed exposure models do not duplicate natural exposure and may not reflect behavioral or physiological impairments that occur under more realistic exposure conditions.
