A total of 12 samples of egg rolls retailed in three locations in Abeokuta and a laboratory prepared sample serving as control were analyzed for their microbial load and presence of heavy metals (Lead, Cadmium, Chromium). The samples were analyzed for bacteria using standard procedures. Analysis of the food samples showed that total viable bacterial count ranged from 1.2 x 105 to 4.2 x 105 cfu/g, total staphylococcus count ranged between 1.2 x 104 and 6.4 x 104 cfu/g, coliform count ranged from 1.0 x 104 to 3.0 x 104cfu/g, total campylobacter count ranged between 1.0x104 and1.3x104 cfu/g and there were no growths for the total listeria count. Five bacteria genera were isolated including Staphylococcus aureus, Escherichia coli, Klebsiella aerogenes, Salmonella typhi, Campylobacter coli. Cadmium and Chromium contamination ranged from 3.50±0.71 - 12.50±0.71 and 0.75±0.35 - 3.50±0.00 respectively. Statistical analysis of the heavy metals shows a significant difference (p<0.05) between the control and samples. The level of microbial contamination could be associated with inadequate handling and processing by processors and vendors, contamination caused by either poor hygiene or poor quality of water used. Moreover, contamination of cadmium and chromium in all the samples could be incident upon the water used in producing it, however lead was absent in all the samples. It is therefore recommended that health education should be done for food handlers and consumers about food safety.

Abstract The primary objectives of this study are to 1) assess the quality of each volunteered geographic information (VGI) data modality (text, pictures, and videos), and 2) evaluate the quality of multiple VGI data sources, especially the multimedia that include pictures and videos, against synthesized water depth (WD) derived from remote sensing (RS) and authoritative data (e.g. stream gauges and depth grids). The availability of VGI, such as social media and crowdsourced data, empowered the researchers to monitor and model floods in near-real-time by integrating multi-sourced data available. Nevertheless, the quality of VGI sources and its reliability for flood monitoring (e.g. WD) is not well understood and validated by empirical data. Moreover, existing literature focuses mostly on text messages but not the multimedia nature of VGI. Therefore, this study measures the differences in synthesized WD from VGI modalities in terms of (1) spatial and (2) temporal variations, (3) against WD derived from RS, and (4) against authoritative data including (a) stream gauges and (b) depth grids. The results of the study show that there are significant differences in terms of spatial and temporal distribution of VGI modalities. Regarding VGI and RS comparison, the results show that there is a significant difference in WD between VGI and RS. In terms of VGI and authoritative data comparison, the analysis revealed that there is no significant difference in WD between VGI and stream gauges, while there is a significant difference between the depth grids and VGI.

Climate change has an important impact on the environment. As it degrades the quality of water, soil, and area, it also spreads the distribution of many toxic elements, specifically heavy metals and pesticides. The impact of climate change on contamination with heavy metals and pesticides has been well investigated and discussed. The influence of these elements on human health is obviously exacerbated following their extended distribution. Moreover, a wide range of health problems have been associated to such intoxication, among which impairment and dysfunction of the nervous system are prominent. In this chapter, the authors will shed light on two most common neurological diseases such as epilepsy and stroke affecting people worldwide arising from food and water contaminations, mainly with heavy metals and pesticides.

The objectives of this trial were to estimate prevalence of bacteriospermia, to determine the bacterial load, and to isolate the types of bacteria as well as to assess the association between bacterial load and sperm quality traits in cryopreserved bull semen in field conditions in the South Wollo Zone. A total of 309 cryopreserved straws of semen from the Holstein Friesian (HF)-cross bull (n = 180 straws) and pure Jersey bull (n = 129 straws) were investigated. Bacteriological assessments of the presence of aerobic bacteria, estimation of bacterial count and bacterial isolation, as well as semen quality were performed. Aerobic bacterial contamination was prevalent in 38.8% of the semen straws. No significant difference in the prevalence of bacteriospermia was observed among bulls although the HF-cross bull had a higher prevalence (40.0%). But, significant difference in prevalence of bacteriospermia was found among semen ejaculates of the same bull. The risk of bacteriospermia in the HF-cross bull was higher (Odds ratio = 1.86, 95% CI = 0.168–20.26) compared to Jersey although not significant. Overall average bacterial load of 50.38 ± 16.29 colony-forming units (CFU)/ml (from nil to 1318.20 CFU/ml) was found. No significant difference in bacterial count among bulls and their ejaculates was observed. Moreover, correlation analysis revealed that the proportions of motility, live, and normal morphology were negatively influenced by an increase in the bacterial contamination of semen. In this study, three isolates of coagualse-negative Staphylococcus species and one isolate of Corynebacterium species were found. Average percentages of sperm motility (48.35 ± 1.23), live (66.08 ± 1.0), and normal morphology (80.62 ± 1.24) were observed. It was concluded that cryopreservation does not guarantee the quality of semen from bacterial contamination. Hence, meticulous care should be adopted to prevent contamination of semen by bacteria during collection, transportation, processing, and storage times.

Abstract. In August and September 2002, concentrations of heavy metals (copper, lead, and zinc) were 21-74% more than in previous years in Lithuanian rivers. Such a sudden increase in heavy metal pollution reduces the value of any water body for fishing or recreation and poses a potential risk to the environment and to human health. Droughts in the summer of 2002 led to forest and peat bog fires all over Lithuania and may have caused the increase in concentrations of heavy metals detected in Lithuanian rivers in August 2002. The fires could have changed the pH in the top layers of the soil, overcome geochemical barriers in the soil and enabled heavy metals to migrate from the soil to the groundwater and from river bottom sediments to the surface water.

A má qualidade dos corpos de água exerce influência direta sobre a saúde da sociedade, podendo causar doenças de veiculação hídrica, que levam a morte milhões de pessoas no mundo. Neste cenário, o presente estudo objetivou identificar as relações existentes entre condições ambientais e doenças de veiculação hídrica no Assentamento Rural Serra Grande, situado na sub bacia hidrográfica do Riacho Natuba, no município de Vitória de Santo Antão, em Pernambuco. Foram escolhidas seis nascentes, fazendo-se medições de parâmetros de qualidade de água, comparando-se os resultados das análises com os padrões estabelecidos pela Resolução Conama Nº 357/05 e Portaria do Ministério da Saúde Nº 2914/11. Para identificar a ocorrência de doenças de veiculação hídrica no assentamento procedeu-se a aplicação de questionários junto à comunidade local, representantes do Posto de Saúde e da Secretaria de Saúde Municipal, abordando aspectos sobre a incidência dessas doenças e respectivos programas de saúde implementados. Os resultados obtidos mostraram que as nascentes representavam a principal fonte de água para o consumo doméstico, a irrigação e a dessedentação animal. No entanto, as análises de qualidade de água apontaram que a mesma não apresentava condições apropriadas ao consumo humano direto, requerendo prévio tratamento. Em relação ao perfil de ocorrência das doenças de veiculação hídrica, constatou-se que as verminoses e protozooses são as doenças que mais acometem a população.   A B S T R A C T The poor quality of water bodies shall exercise direct influence on the health of society, causing hydro term placement diseases leading to death millions of people worldwide. In this scenario, the present study aimed to identify the relationship between environmental conditions and hydro term placement diseases in the Rural Settlement Serra Grande, located in the Sub-basin of the Natuba rivulet, in the municipality of Vitória de Santo Antão, Pernmbuco State, Brazil. Six springs  were chosen for sample collections and determination of  water quality parameters, comparing the results with the quality standards established by CONAMA ( Brazilian National Environmental Council) Resolution Nº 357/05 and Ordinance of the Ministry of Health (Brazil) No. 2914/11. Questionnaires were applied to local social actors: community, health and Municipal Health Secretariat, addressing aspects of water diseases and health programs implemented. The results obtained showed that the springs were the main source of water for domestic consumption, irrigation and animal watering in the studied area. However, the water quality analyses showed that these springs  do not show appropriate sanitary conditions to direct human consumption, requiring treatment. In relation to the profile of hydro term placement diseases occurrence, it was observed that the worms and protozooses are the diseases that most affected the local population.

This study focuses on the quality of the organic matter that reaches the sediment from Boa Viagem Beach and through the evaluation of the total bacterial count, the electron transport system activity (ETSA), the esterase activity (EST), as well as the protein and the organic matter contents. Seasonal variations of organic matter, protein content and the number of bacteria were particularly notable in the summer. ETSA reached a maximum of 7.48 µl O2 h-1 g-1 in the summer. EST activity presented a different pattern once it reached a maximum of 0.17 µg fluorescein h-1 g-1 in the winter. The temporal variation of ETSA and EST activity indicated that biopolymers predominated in the winter, and oligomers or monomers predominated in the summer. These results suggest that organic carbon turnover is more likely to be controlled by organic matter quality. The heavy metals concentrations, especially for Cu, Zn, Ni and Cr, indicated absence of the inhibition of dehydrogenase activity, and they are not bioavailable in the EC50 values

Abstract Background IBD has been shown to increase the rates of anxiety and depression amongst diagnosed individuals, with a prevalence rate of approximately 15- 20%. Chronic diseases such as IBD can have a significant impact on productivity at work (presenteeism). This can lead to emotional distress, poor quality of life and cost effects on employers. The primary aim of the study was to assess the prevalence of psychological problems, exercise levels and presenteeism at work among IBD patients. Methods This was a multicentre international study whereby IBD patients (&gt;18 years) in clinical remission over the last year, were asked to answer an anonymous questionnaire. Demographic data, type of IBD, current and previous medication, admissions to hospital, history of psychiatric referrals, Stanford Presenteeism Scale (SPS-6), Godin Score (exercise related score) were collected. Exclusion criteria included patients with IBD flares requiring corticosteroids in the previous 12 months. Results 573 patients (CD: n=318) from 8 European Centres and Israel participated in the study. The mean patient age was 39.9 years (SD+/- 13.0). 21.6% were smokers and 48.5% were non-smokers. The rest were ex-smokers. 10.9% of patients had a diagnosis of depression/anxiety prior to the diagnosis of IBD, whereas this increased to 20.6% post-IBD diagnosis, this being significantly commoner in the CD cohort (23.0%, p&lt;0.05) and in females (55.8%, p&lt;0.05). 37.7% of patients had been to a psychiatrist or a psychologist (41% of CD, p&lt;0.05) with 11.7% of patients being on psychiatric medication (14.5% of CD, p&lt;0.05). Low presenteeism at work was evident in 34.7%, with no statistically significant difference between UC and CD patients (p=0.5). 39.9% had a Godin Exercise Score being in the active range, 38.8% had a sedentary/insufficient exercise score. The rest were moderately active. Patients diagnosed with depression/anxiety had a more sedentary lifestyle. Conclusion In our study 37.7% of patients were referred for psychological help. This can have several effects including poor presenteeism at work (34.7%) and reduced efficiency. These issues are commoner in patients with CD than in UC. Active involvement of a psychologist/ psychiatrist as part of the IBD team should be routine as to improve the patient’s quality of life.

The aim of the work was establishment of research green roofs on Mendel University in Brno. The experimental green roofs were established in August 2015 and it is based on current issues of rainwater management and the quality of storm water launched into recipients or sewage system. There is a valid legislation addressing the management of rainwater in environment – decree no. 268/2009, Coll., and decree no. 269/2009, Coll. Four experimental plots were created and placed in Mendel University Campus. It was hypothesized that different types of experimental plots will result in different amount of retained water and in different quality of water runoff. Resulting hypotheses proved statistically significant difference between the height of rainfall and runoff height on individual types of green roofs. In addition, it was shown that the different types of roofs prove statistically significant difference in the ability to reduce runoff (retention efficiency).

The seasonal investigation about the water quality from Damanganga river estuary on two habitats downstream and upstream was carried out from January to December 2019 containing three major seasons: winter, summer and monsoon. For this monitoring activity total 29 parameters (24 physico-chemical parameters and 5 heavy metals) were analyzed. Multivariate analyses suggested inter dependency among these studied parameters. Water Quality Index is computed based on the major fluctuated and affected parameters. The calculated values of WQI for all three seasons ranged from 122.84 to 173.82 which suggested poor water quality of the water body. WQI values of the investigation area proposed that the estuarine water quality is deteriorated due to high value of presented heavy metals (Aluminum, Iron, Manganese, Boron and Zinc), Chloride, Ammonium and Sulfate in water sample. In this case, the downstream station is having accessional pollutant contaminations while the upstream station is having diminutive pollutant contaminants. Temporally, the dominant frailty found during the winter followed by summer and monsoon. This study field exhibited poor quality of water; the reason behind this might be the impressive surrounding industrial zone as well as other anthropogenic activities. There is quite normal probability distribution expressed by the represented water quality data at the both habitats. The Bray-Curtis cluster analysis shows different percentage similarity level between the water quality parameters.
