“…Cell disintegration was also observed due to the increase of membrane permeability (Figure 20). Chitosan BNMs also increased the reagent oxygen species (ROS) production in F. oxysporum, that can increase the oxidative stress, even cause the release of cytochrome C, leading to apoptosis (Figure 21) [84]. In nature, chitin, the source of chitosan, exists as long and straight microfibrils, that have an indeterminate length and a diameter of 2.8 nm [79].…”

This paper describes the ecotoxicological effects of nanomaterials (NMs) as well as their testing methods. Standard ecotoxicity testing methods are applicable to nanomaterials as well but require some adaptation. We have taken into account methods that meet several conditions. They must be properly researched by a minimum of ten scientific articles where adaptation of the method to the NMs is also presented; use organisms suitable for simple and rapid ecotoxicity testing (SSRET); have a test period shorter than 30 days; require no special equipment; have low costs and have the possibility of optimization for high-throughput screening. From the standard assays described in guidelines developed by organizations such as Organization for Economic Cooperation and Development and United States Environmental Protection Agency, which meet the required conditions, we selected as methods adaptable for NMs, some methods based on algae, duckweed, amphipods, daphnids, chironomids, terrestrial plants, nematodes and earthworms. By analyzing the effects of NMs on a wide range of organisms, it has been observed that these effects can be of several categories, such as behavioral, morphological, cellular, molecular or genetic effects. By comparing the EC50 values of some NMs it has been observed that such values are available mainly for aquatic ecotoxicity, with the most sensitive test being the algae assay. The most toxic NMs overall were the silver NMs.

“…It is a simple linear polysaccharide that constitutes the β-1-4 linked D-11 glucosamine (GlcN) and N-acetyl-D-glucosamine (GlcNAc) (Katiyar, Hemantaranjan, Singh, & Bhanu, 2014). Chitosan is known to induce plant growths (Dzung, Khanh, & Dzung, 2011), contain antifungal (Atai, Atai, Amini, & Salehi, 2017;Dananjaya et al, 2017) and antibacterial properties (Cui, Bai, Rashed, & Lin, 2018;D'Almeida et al, 2017). Investigation on the role of nano-chitosan against pathogens have been reported in rice (Pham et al, 2019) and tomato (Chun & Chandrasekaran, 2019;Santiago et al, 2019).…”

Concern over indoor fungal growth has increased over the last decades. Research that relates human health issues to the deterioration of indoor air quality due to microbiological pollutants have been accumulated (Rath et al. 2011;Weber 2012;Täubel and Hyvärinen 2015). In addition, since the 1980s, it has been registered that there is an increase in the occurrence of natural disasters such as floods and extreme rainfall, on a global scale, which has enhanced the problems related to biodeterioration in indoor buildings (Bloom et al. 2009;Chow et al. 2019; EASAC 2018). It is worth mentioning that these kinds of events are directly related to fungal growth since water is a key factor in the development of these microorganisms (Johansson et al. 2013;Møller et al. 2017). Considering the strong impact of indoor fungi on public health, several guidelines have been proposed from different European and North American institutions. These institutions include the
