Engineered nanomaterials in the environment: Are they safe?

Insight into the Antibacterial Activity of Selected Metal Nanoparticles and Alterations within the Antioxidant Defence System in Escherichia coli, Bacillus cereus and Staphylococcus epidermidis

“…One of the topics of the currently ongoing scientific debate on the toxicity of NPs is their potentially destructive effect on the functioning of microorganisms. Despite the huge amount of scientific data in this field, there is still controversy about the impact of NPs on microorganisms, especially these newly designed engineered NPs [7,8,24,25].…”

Improved anaerobic degradation of purified terephthalic acid wastewater by adding nanoparticles or co-substrates to facilitate the electron transfer process

“…The leakage or discharge of nanoparticulate materials may result in environment-related risks in aquatic environments. 48 However, these potential environmental risks can be avoided by reducing the toxicity of nanoparticulate materials or by consideration of recycling nanoparticulate materials, such as restoring Fe 3 O 4 nanoparticles using their magnetic properties. 22 Based on a comprehensive comparison, TiO 2 nanoparticles are highly recommended to be selected as exogenous materials to degrade low-concentration PTA wastewater due to their cheaper price and difficulty in leaching into the effluents.…”

Nanoimpact in Plants: Lessons from the Transcriptome

“…Engineered nanomaterials represent a fast-growing market, as they have a high potential for product adoption in a variety of industries including aerospace and vehicle production, construction, chemical catalysis, or agri-food sectors [15,16,19]. Rapid developments in biomedical technology and pharmaceutical research are also expected to augment the industrial production of NPs in the years to come [20,21]. These materials are increasing their presence in consumer products and domestic devices, mostly as coatings to improve mechanical, optical, or antibacterial properties.…”
