“…This indicates changes in the balance between Cl-DBPs and Br-DBPs during distribution to consumers, potentially explained by the different stabilities of Cl-DBPs and Br-DBPs, where Br-DBPs are less stable. 27,34,35 Debromination by hydrolytic reaction is faster than dechlorination as the Br-C bond is longer and its dissociation energy lower, 36,37 i.e., the C-Br bond is weaker. The degradation rate increases under alkaline conditions (Fig.…”

“…At STO, the proportion of DBPs containing two chlorine atoms decreased from ∼18% after disinfection to <1% at the tap, possibly connected to differences in dehalogenation rates depending on the number of halogen substituents. 36 DBPs solely detected in tap waters probably formed after longer contact times and were characterized by lower average O/C ratios (LIN and STO) and higher average mass (all DWTPs) (Table S7, † right column) and are listed in Table S9. † At MAL, the DBPs detected at the tap were substantially different from those detected at the DWTP (Fig.…”

“…In addition, the removal of DOM generally promotes the formation of brominated compounds favouring the reaction of chlorine with Brinstead of DOM. This could induce a greater toxicity, despite an overall decrease of DBP concentrations [82][83][84][85][86]. There is currently no economically feasible method to remove the halogens precursors of DBP, bromide and iodide.…”

“…Disinfectants used in premises have a different focus and mechanism of action on microbial cells (Jiang et al, 2018;Maertens et al, 2018;Paliy et al, 2018;Zazharskyi et al, 2020). Currently, preparations of ammonium compounds and colloidal silver are widely used for disinfection (Park et al, 2009;Ding et al, 2019;Diaz et al, 2019). Although the antibacterial properties of silver have been known for many centuries, the exact mechanism of this action remains the subject of discussion.…”

A disinfectant was created for aerosol disinfection of premises in the presence of poultry, which will help reduce microbial contamination of premises, increase survival, weight of poultry and economic efficiency of meat production in general. The preparation based on essential oils can be used for disinfection in the presence of poultry and at the same time exhibits a therapeutic and prophylactic effect on respiratory infections. This disinfectant has a colloidal solution of silver (Ag), benzalkonium chloride and essential oils of thyme, fir and eucalyptus. The preparation based on essential oils contains (per 100 g): benzalkonium chloride – 16.0 g; thyme oil – up to 2.0 g; eucalyptus oil – up to 2.0 g; fir oil – up to 2.0 g; colloidal solution of silver (Ag) – 20–30 mg; distilled water - up to 100 cm3. Aerosol sanitation of indoor air was carried out with 0.3% solution of preparation in the period before housing poultry and once a day from the 20th to the 35th day of growing broilers with aerosol cold mist generator Dyna-Fog Tornado (model 2897, construction type – ULV-electric spray gnerator, manufacturer – Curtis Dyna-Fog, Ltd., USA) at a dose of 50.0 cm3 per 1 m3 at an exposure of 60 minutes. The size of the aerosol particles is 20 μm. On days 1, 4, 8, 11, 15, 28, 37, and 42, the chickens were weighed, and the blood was taken for examination. Blood was examined to study the number of red blood cells, hemoglobin content, the bactericidal activity of blood serum, phagocyte activity of leukocytes, lysozyme activity of blood serum. According to the results of the research, the technological modes of air disinfection of poultry premises in the presence of broiler chickens were substantiated during the use of preparation, which contains nanoparticles (NP) of silver, benzalkonium chloride and essential oils. The optimal mode of aerosol treatment of poultry houses using a 0.3% solution preparation based on essential oils is 50 mL/m3 of a room with a 60-minute exposure. The use of air disinfection in the presence of chickens during broiler rearing and one treatment per day from 20 to 35 days of the chickens’ growth reduced the microbial pollution of indoor air. Thus, the concentration of microbial cells in the room where the chickens were kept was 230.2 ± 15.6 thousand microbial cell/m3. Sixty minutes after disinfection, the concentration decreased to 1.4 ± 0.4 thousand microbial cell/m3. In addition, the bodyweight of chickens at 6 weeks increased by 449.4 ± 16.3 g (15.9%) compared with the controls. The method and mode of air treatment did not adversely affect the development of the internal organs of the poultry and their physiological state, which is confirmed by studies of the morphological parameters of the chicken blood. The data obtained indicate a positive effect of the developed methods and modes of aerosol air treatment with the preparation based on essential oils on the growth and development of broilers.
