Abstract: Oman, being a semi-arid country, is in great need for extensive reuse practices of treated wastewater effluents. However, these practices need to be environmentally and economically feasible under the prevailing sophisticated treatment systems, inadequate infrastructure including sewers and wastewater-treatment plants (WWTPs). This study attempts to provide decision makers with a comprehensive characterisation of treated wastewater effluents in Muscat and to assess public opinions towards various reuse options of treated wastewater. Results from characterisation of the treated wastewater indicate great performance of the WWTPs in removing biological oxygen (O 2 ) demand (BOD) and chemical oxygen demand (COD), as the maximum BOD and COD observed were less than 4 and 60 mg/l, respectively. The turbidity was found very low (below 3 nephelometric turbidity units), including total suspended solids of 13 mg/l. Most of the results showed relatively low counts of the total coliform bacteria except where a high variation was observed (400–2400 most probable number/100 ml). However, the aforementioned water quality indicators were able to meet Omani standards with the exception of a few parameters. In addition, the survey showed that the public had a general understanding of the different options of treated wastewater applications including their treatment procedures.

Abstract: Studies on the assessment of indoor air pollutants in terms of concentration and characterization in the Gulf Cooperation Council (GCC) countries have been recently carried out. This review assesses the health effects associated with indoor air pollution exposures in GCC, including other air pollutants (siloxanes, flame retardants, synthetic phenolic antioxidants) which were not explored in a previous study. In addition, the influence of ventilation conditions due to different indoor environments was also investigated. It was revealed that there is a lack of human health assessment studies on most indoor air pollutants in almost all GCC countries, except the United Arab Emirates, Kingdom of Saudi Arabia and Kuwait, where few attempts were made for some specific pollutants. Commonly reported plausible health effects potentially associated with indoor air pollution were related to respiratory symptoms and sick building syndrome (SBS). Many of the current health assessment studies in GCC countries were based on predictions and/or estimates of exposures rather than clinically based observational studies. Measured ventilation levels and indoor air velocities in most buildings failed to meet the American Society of Heating, Refrigerating and Air-conditioning Engineers (ASHRAE) threshold limits of 8 L/s and 0.18–0.25 m/s, respectively. Additionally, limited studies have investigated respiratory symptoms and SBS potentially attributable to poor ventilation in the region. It is highly recommended that future indoor air quality (IAQ) studies in GCC should focus more on epidemiologic and intervention studies.

Abstract: This paper presents the reviews of scientific papers published in 2018 issues on the effects of anthropogenic pollution on the aquatic organisms dwelling in freshwater ecosystem at global scale. The first part of the study provides the summary of relevant literature reviews followed by field and survey based studies. The second part is based on categories of different classes/sources of pollutants which affect freshwater organism. This is composed of several sections including metals and metalloids, wastewater and effluents, sediments, nutrients, pharmaceuticals, polycyclic aromatic hydrocarbons, flame retardants, persistent organic pollutants, pharmaceuticals and illicit drugs, emerging contaminants, pesticides, herbicides, and endocrine disruptors. The final part of the study highlights the reviews of published research work on new pollutants such as microplastics and engineered nanoparticles which affect the freshwater organisms. PRACTITIONER POINTS: Heavy metals concentrations should be assessed at nano-scale in aquatic environment. Air pollutants could have long-term effects on freshwater ecosystem. Future studies should focus on bioremediations of freshwater pollution.

Abstract: Hospital-noise levels can induce physiological responses and affect sleep quality, which could contribute to cardiovascular-related health problems. Till date, high-resolution hospital noise exposure assessment studies have not received much attention in Oman. This study aims at assessing sound pressure levels across hospital wards and intensive care unit (ICU) rooms to determine annoyance and potential health effects based on perception and risk estimates. An indoor exposure assessment using high precision noise sensors was conducted in a female medical ward (FMW), isolated ward (SLW), emergency ward (EMW), and intensive care unit (ICU) in a public hospital in Muscat city, Oman. Self-administered questionnaire was randomly distributed among respondents using both online and field survey approach to ascertain annoyance, health effects, and potential risks associated with exposure. The study found that 24-h noise levels (L

Abstract: Recessive mutations in CLN7/MFSD8 usually cause variant late-infantile onset neuronal ceroid lipofuscinosis (vLINCL), a poorly understood neurodegenerative condition, though mutations may also cause nonsyndromic maculopathy. A series of 12 patients with nonsyndromic retinopathy due to novel CLN7/MFSD8 mutation combinations were investigated in this study. Affected patients and their family members were recruited in ophthalmic clinics at each center where they were examined by retinal imaging and detailed electrophysiology. Whole exome or genome next generation sequencing was performed on genomic DNA from at least one affected family member. Immunofluorescence confocal microscopy of murine retina cross-sections were used to localize the protein. Compound heterozygous alleles were identified in six cases, one of which was always p.Glu336Gln. Such combinations resulted in isolated macular disease. Six further cases were homozygous for the variant p.Met454Thr, identified as a founder mutation of South Asian origin. Those patients had widespread generalized retinal disease, characterized by electroretinography as a rod-cone dystrophy with severe macular involvement. In addition, the photopic single flash electroretinograms demonstrated a reduced b- to a-wave litude ratio, suggesting dysfunction occurring after phototransduction. Immunohistology identified MFSD8 in the outer plexiform layer of the retina, a site rich in photoreceptor synapses. This study highlights a hierarchy of MFSD8 variant severity, predicting three consequences of mutation: (1) nonsyndromic localized maculopathy, (2) nonsyndromic widespread retinopathy, or (3) syndromic neurological disease. The data also shed light on the underlying pathogenesis by implicating the photoreceptor synaptic terminals as the major site of retinal disease.

Abstract: The World Health Organization (WHO) recognises air pollution as a serious public health concern in many developing countries due to the influx of energy-intensive industries with limited planning and exposure mitigation strategies. Due to industrial expansion and release of associated air pollutants in Oman, the US Environmental Protection Agency human health risk assessment (HHRA) model was used to determine the non-carcinogenic hazard associated with exposure to industrial emissions. Across the three industrial cities (Nizwa, Sur and Rusayl), the study found ambient average concentrations (μg/m 3 ) of 1 h carbon monoxide (CO) (606–1974), nitrogen dioxide (NO 2 ) (7.7–43.9) and sulfur dioxide (SO 2 ) (4.8–9.0) and 24 h PM 2.5 (7.3–7.8) and PM 10 (38.7–51.5) to be significantly lower than both the Ministry of Environment and Climatic Affairs (MECA) and WHO limits. The HHRA analysis showed that exposure to the air pollutants produced low non-carcinogenic adverse health effects, as the hazard quotient (HQ) was found to be among the population. However, there was an increase in HQ for WHO reference exposure level (REL) values compared with that of MECA this is due to the relaxed/high REL limits of the latter. Future epidemiological studies involving long-term air pollution exposure assessment and health data may improve the reliability of the current HHRA estimates.
