“…Thus, the conclusions from this experiment are not surprising. An immediate conclusion would therefore be that antibiotic pollution should be considered a global concern not only in the context of pathogen resistance and human health [22] but also for processes involving magnetic field sensing such as migration in the air, on land, or at sea, pollination, habitat choice, etc.…”

Magnetoreception is a sense that allows the organism to perceive and act according to different parameters of the magnetic field. This magnetic sense plays a part in many fundamental processes in various living organisms. Much effort was expended in finding the 'magnetic sensor' in animals. While some experiments show a role of the ophthalmic nerve in magnetic sensing, others show that effects of light on processes in the retina are involved.According to these inconclusive and puzzling findings, the scientific community has yet to reach an agreement concerning the underlying mechanism behind animal magnetic sensing. Recently, the symbiotic magnetotaxis hypothesis has been forwarded as a mechanistic explanation for the phenomenon of animal magnetoreception. It suggests a symbiotic relationship between magnetotactic bacteria (MTB) and the navigating host. Here we show that in contrast to the control group, antibiotic treatment caused a lack of clear directionality in an Emlen funnel experiment. Accordingly, the antibiotics treatment group showed a significant increase in directional variance. This effect of antibiotics on behaviors associated with animal magnetic sensing is, to the best of our knowledge, the first experimental support of the symbiotic magnetotactic hypothesis.

“…Antibiotics are also extensively used in hospitals, being one of the groups with higher loads in hospital wastewaters [51]. This therapeutic group is particularly critical as it can promote antibioticresistant bacteria (ARB) propagation into public wastewaters, breeding with the negative consequence of curative effects of antibiotics against humans and animals pathogens [53]. In Spain, the consumption of antibiotics ranged from 22 DHD in 1992 to 19.7 DHD in 2009, with an extraordinary increase in fluoroquinolones [54].…”

Hospitals are one of the key contributors of pharmaceutical contaminants of emerging concern to the sewer systems. Hospitals wastewaters contain concentrations of pharmaceutical compounds between 3 and 150, which are higher than urban wastewater streams. However, dedicated treatments of the hospital effluents before discharge to the sewer system are not compulsory. Besides, conventional wastewater treatment plants have not been designed to remove pharmaceutical compounds effectively, and consequently, these micropollutants can reach the aquatic ecosystems. The removal of pharmaceutical compounds in real hospital wastewater was gaged using three different microbial cultures (white rot-fungus Trametes versicolor, microalga Isochrysis galbana, and a mixed culture of non-sulfur purple phototrophic bacteria). Before and after bioassays of the hospital wastewater, environmental hazard quotients were used to evaluate the biological treatment efficiency. Up to 45 out of the 79 compounds included in the analytical method were noticed in the hospital wastewater, with a predominance of analgesics/anti-inflammatories (acetaminophen, ibuprofen, ketoprofen, and naproxen). It was followed by antibiotics (azithromycin, ciprofloxacin, and ofloxacin, out of which the first two are included in the watch list of substances for monitoring in water in 2020) and anti-hypertensive drugs. Isochrysis galbana reached a reduction of 45% of the total concentration of pharmaceuticals, whereas Trametes versicolor and mixed culture of purple phototrophic bacteria improved the reductions up to 69% and 76%, respectively. Moreover, potential environmental risk compounds (antibiotics, particularly ciprofloxacin and ofloxacin) were removed by Trametes versicolor in higher extension, obtaining a total hazard quotient reduction higher than the other two cultures. Removal efficiency and environmental risk assessment of remaining PhACs were used to evaluate the performance of the new biological systems for the treatment of emerging pollutants. According to both criteria, T. versicolor seems the most capable alternative for removing pharmaceutical compounds in hospital wastewater effluents.

“…Antibiotic is characterized with incomplete metabolism within human body thus, it is abundantly discharged with wastes into the environment (Gomes, Costa, Quinta-Ferreira, & Martins, 2017;Mandaric et al, 2017), both antibiotics and personal care product form components of municipal wastewater (Balakrishna, Rath, Praveenkumarreddy, Guruge, & Subedi, 2017;Wang, Huang, & Wei, 2018). PPCp exists in the environment at a very low concentration (Richardson et al, 2017), they can however be a source of serious health concerns such as drug resistance development, endocrine disruption and carcinogenicity (Bai et al, 2018;Inyinbor, Bello, Fadiji, & Inyinbor, 2018).…”

The serious water scarcity experienced across the globe and the desire for sufficient food production all year round to combat hunger, poverty and malnutrition necessitate the need for wastewater reuse in irrigation. Wastewater has varied compositions that affect the growth of different crops positively, they may also be a source of dangerous pollutant. Heavy consumption of vegetables have been encouraged for its nutritional and health advantages. Hence, their production and cultivation have increased globally. While the nutritional advantage of vegetables is appealing, their high susceptibility to harbor and spread pathogenic microbes call for serious concern. Activities such as transportation, improper handling and packaging amongst others are sources of vegetable contamination. Irrigation water and techniques however present greater danger. Agro-industrial wastewater of a ready-to-eat vegetable (RTEv) industry operating a closed system may reintroduce microbes to vegetable gardens. The use of raw domestic wastewater, either black or grey water in vegetable cultivation presents attendant challenges which must be handled with utmost precaution. This review is focused on the dangers associated with the reuse of agro-industrial and domestic wastewater, precautions required as well as possible preventive/reduction measures. The possible dangers associated with "crude irrigation techniques" used in vegetable cultivation in the Southwestern part of Nigeria are presented. This work will no doubt serve as a tool for policy makers and environmentalists in enlightenment and awareness campaigns in educating most rural dwellers who are ignorant of these dangers.
