“…Labeo rohita was the most sensitive species. Micronuclei are formed at different periods of the cell cycle during cell division, after attack by environmental toxicants (Bolognesi and Hayashi 2011; Butrimavičienė et al 2018). The micronucleus test was originally developed for mammalian species but has now been widely used in fish (Ahmed et al 2011; Bolognesi and Hayashi 2011).…”

The present study was conducted to assess the genotoxic potential of water from the Helong Reservoir, which was designated as a strategic drinking water source by the Guangdong Provincial Government of China in October 2016. Four kinds of common indigenous fish samples (Labeo rohita, Cirrhinus molitorella, red tilapia, and Oreochromis niloticus) were collected at 6 sampling sites during the period from July to November 2020. Fish from the clean drinking water source of the upper reaches of the Liuxihe Reservoir in Guangzhou were collected as the control. Both the alkaline single cell gel electrophoresis assay and the micronucleus test were used to detect DNA damage and the micronucleus rate in erythrocytes of fish samples, respectively. The results indicated that there was a significant increase in comet tail length, Olive tail moment, and micronucleus rates of all fish samples compared with those of the control (p < 0.05). The order of sensitivity to DNA damage and micronucleus formation was Labeo rohita > Cirrhinus molitorella > red tilapia > Oreochromis niloticus. The results of the 2 kinds of experiments were in perfect agreement with each other. We conclude that there are obvious genotoxic effects from the water in the Helong Reservoir. As a strategic drinking water source, the safety of the Reservoir water quality should be considered. The local government should put the restoration of the Helong Reservoir water quality on the agenda as soon as possible.

“…Inadequate knowledge by dairy industry organizations and treatment plants on wastewater characteristics and its effect on the municipal wastewater system and receiving water bodies (Gulf of Riga) leads to damage to the environment. Studies revealed the potential sediment toxicity in Gulf of Riga by using acute toxicity bioassay (survival test) for many aquatic lives (Strode et al ., 2017; Butrimavičienė et al ., 2018). The presence of unmeasured contaminants discharged from municipal water treatment plants could be responsible for toxicity to aquatic animals in Gulf of Riga sediments, which may be detrimental to human health.…”

The objective of the research presented in this Research Communication was to access the environmental impact of the Latvian dairy industries. Site visits and interviews at Latvian dairy processing companies were done in order to collect site-specific data. This includes the turnover of the dairy industries, production, quality of water in various industrial processes, the flow and capacity of the sewage including their characteristic, existing practices and measures for wastewater management. The results showed that dairy industries in Latvia generated in total approximately 2263 × 103 m3 wastewater in the year 2019. The Latvian dairy effluents were characterized with high chemical oxygen demand (COD), biological oxygen demand (BOD) and total solids (TS). Few dairy plants had pre-treatment facilities for removal of contaminants, and many lacked onsite treatment technologies. Most facilities discharged dairy wastewater to municipal wastewater treatment plants. The current study gives insight into the Latvian dairy industries, their effluent management and pollution at Gulf of Riga due to wastewater discharge.

“…Because of its irreparable nature, the increase in micronuclei is considered a relevant toxicological endpoint. 26,27 The aim of the present study was to pursue nonmutagenic derivatives of emodin that can also be applied to textiles using waterless dyeing methods. Specifically, our group modified the emodin structure by incorporation of one or two acryloyl groups according to the chemistry shown in Figure 1.…”

Traditional textile dyeing processes usually require large quantities of water and energy and generate wastewater that can be harmful to the environment. Dyeing in supercritical carbon dioxide (sc‐CO2) media is promising in textile coloration due especially to it providing a waterless process and eliminating the need for an energy intensive drying step. The natural anthraquinone emodin showed promising results for dyeing different fibres through sc‐CO2 process. However, emodin is mutagenic. The aim of this study was to develop non‐mutagenic derivatives of emodin that can be applied to textiles using sc‐CO2. Emodin structure was modified incorporating acryloyl groups, which are considered suitable for decreasing potential for DNA intercalation, and thus mutagenicity. The presence of acryloyl groups would also enable atmospheric plasma induced bonding with fibres. Molecular modelling studies showed that emodin derivatives became less planar with increasing number of attached acryloyl groups, making intercalation unlikely. The derivatives produced were tested to assess mutagenicity in vitro (Salmonella/microsome assay, TA1537, 10% S9) and in vivo (micronucleus test in hemocytes of aquatic crustacean). We found that emodin can be derivatised using acryloyl chlorides to give mono‐ and di‐acrylate esters suitable for dyeing polyester fibres in sc‐CO2. However, the new dyes presented mutagenicity for both in vitro and in vivo. Although the derivatives provided greenish‐yellow alternatives to emodin for dyeing synthetic fibres, they do not appear to be viable alternatives from the point of view of preserving human and environmental health. Plasma bonding studies are underway.
