“… The adsorption of organochlorines (atrazine, hexachlorobenzene, pentachlorobenzene, and 3, 3′, 4, 4′-tetrachlorobiphenyl) by TiO 2 nanoparticles increases the bioaccumulation of these contaminants to algae [ 223 ]. The co-exposure of nanoparticles (such as TiO 2 , Ag, Al 2 O 3 , graphene, and CNTs) with PAHs, organochlorine pesticides (OCPs), and polybrominated diphenyl ether (PBDE) in soil to Ipomoea aquatic, Cucumis sativus L., Zea mays L., Spinacia oleracea L., and Cucurbita moschata promotes the uptake and accumulation of organic contaminants in crop plants [ 233 ]. Co-exposure of graphene nanoparticles at 50 mg/kg level (4–20 nm·size) substantially increased the bioaccumulation of organic contaminants through adsorption, followed by co-transfer into crop tissues [ 233 ].…”

The manufacturing rate of nanoparticles (10–100 nm) is steadily increasing due to their extensive applications in the fabrication of nanoproducts related to pharmaceuticals, cosmetics, medical devices, paints and pigments, energy storage etc. An increase in research related to nanotechnology is also a cause for the production and disposal of nanomaterials at the lab scale. As a result, contamination of environmental matrices with nanoparticles becomes inevitable, and the understanding of the risk of nanoecotoxicology is getting larger attention. In this context, focusing on the environmental hazards is essential. Hence, this manuscript aims to review the toxic effects of nanoparticles on soil, water, aquatic, and terrestrial organisms. The effects of toxicity on vertebrates, invertebrates, and plants and the source of exposure, environmental and biological dynamics, and the adverse effects of some nanoparticles are discussed.

“…Due to the high molar mass and the lipophilicity of high brominated BDEs, plant uptake by the soil-soil moisture-root-plant pathway is of low relevance and restricted to low and medium brominated BDEs (Br 2 -Br 5 ) like BDE-47, BDE-99 and BDE-100 [21,32], even though intrinsic transport of BDE-209 was reported by single studies [33][34][35], but disproved by Wu et al [36], where plant availability of BDE-209 was quantified as 0.3-0.5% of the initial soil concentration and 99.5-99.7% of BDE-209 are solely adsorbed on the soil matrix and the outer side of the roots. Hence, atmospheric uptake of high brominated BDEs is the dominant pathway, even though BDE-209 reveals a low ratio of 0.1% of the atmospheric PBDE pattern [24,37].…”

“…As a result of high bromination, high molecular weight, low mobility and high lipophilicity, BDE-209 as the dominant PBDE in soil is only marginally available for plants at levels of 0.3-0.5% of the initial concentration [36]. Despite the apparently low relevance, the soil -soil moisture -root uptake pathway is still of high relevance as tests with living and non-living roots of different plants showed 3.5-6 times higher BDE-209 levels in the living tissues [49].…”

Flame Retardant and Thermally Insulating Polymers

Polybrominated diphenyl ethers (PBDEs) have been widely used as flame retardants in concentrations up to 30 w% of the total mass of the products. Worldwide consumption of technically relevant PBDE mixtures was about 7500 tons (penta-BDEs), 3790 tons (octa-BDEs) and 56,100 tons (deca-BDE) in 2001 and about 50–60% of this total volume was discharged into environment only by agricultural use of sewage sludges. The use of PBDEs was strictly regulated from 2004 onwards due to their high emission load and their effect as endocrine disrupters, neurotoxins, and fertility reducing agents. Nevertheless, soils worldwide are contaminated by gaseous and particle-bound transport of PBDEs. Therefore, the uptake of PBDEs from contaminated agricultural land via crops and the food chain is a major human exposure pathway. However, uptake and intrinsic transport behavior strongly depend on crop specifics and various soil parameters. The relevant exposure and transformation pathways, transport-relevant soil and plant characteristics and both root concentration factor (RCF) and transfer factor (TF) as derivable parameters are addressed and quantified in this chapter. Finally, based on available crop specific data a general statement about the transport behavior of PBDEs in twelve different crops according to relevant PBDE congeners is given.

“…Danio rerio, commonly known as the zebrafish, is a widely used model organism for screening the eco-toxicological effects induced by environmental pollutants [16][17][18][19] including artificial dyes [7,9,20]. Finally, Cucumis sativus L. is a plant model organism, widely used to evaluate the toxic effects of different types of pollutants, i.e., dyes, heavy metals, and polycyclic aromatic hydrocarbons [7,21,22]. Cucumber seedlings are sensitive indicators of soil pollution, including watering contamination [23].…”

Commercial Red Food Dyes Preparations Modulate the Oxidative State in Three Model Organisms (Cucumis sativus, Artemia salina, and Danio rerio)

The growing environmental spreading of food synthetic dyes and bio-colors have the potential for altering organisms’ redox states. Here, three model species for aquatic pollution trials, Cucumis sativus seeds, Artemia salina cysts, and Danio rerio embryos, were short-term exposed to a fixed concentration of the artificial red E124, and two red bio-colors, cochineal E120, and vegan red (VEGR). In the animal models, we evaluated the total reactive oxygen species (ROS) and the susceptibility to in vitro oxidative stress, and in C. sativus, H2O2 production and antioxidant capacity. We also measured organismal performance indices (routine oxygen consumption in the animal models, dark oxygen consumption, and photosynthetic efficiency in C. sativus). In C. sativus, only E124 increased ROS and affected dark oxygen consumption and photosynthetic efficiency, while all dyes enhanced the antioxidant defenses. In the A. salina nauplii, all dyes increased ROS, while E120 and E124 reduced the susceptibility to oxidative stress. In D. rerio, treatments did not affect ROS content, and reduced oxidative stress susceptibility. Our data show that red food dyes affect the redox state of the developing organisms, in which ROS plays a significant role. We suggest a potentially toxic role for red food dyes with environmentally relevant consequences.
