Every year during monsoon season heavy rain fall and lack of disaster management skills potentially increase the transmission of waterborne diseases, vector borne diseases and viral outbreaks. Due to severe flooding, thousands of people lose their lives and millions are displaced each year. In most of the cases the children who lose their family members are forced into illegal professions of begging, child labor and prostitution which make them prone to sexually transmitted infections. Up to date, no scientific study has been conducted nationwide to illustrate epidemiological patterns of waterborne diseases, vector borne diseases and viral epidemics during flash flood. Mosquito sprays would not be a sufficient approach for dengue eradication; mass awareness, larvicide and biological control by Guppy fishes are also effective strategies to overcome dengue problem. International health bodies and non-governmental organizations must take note of this alerting situation and take adequate steps such as financial/medical aid in order to defeat the after-effects of flood.展开更多

Besides other pollutants, high concentration of uranium above a certain level in drinking water is also hazardous. As water and food are the main sources of uranium intake, it is absolutely imperative that their level of concentrations is monitored regularly for safety of the general public. In this regard, trace amount of uranium in drinking water samples collected from different locations of Faisalabadcity has been carried out using Neutron Induced Fission Track Technique. The water samples along with the standard of known uranium concentration were poured and dried over Lexan track detectors and then irradiated with thermal neutrons in Reactor. After etching, the tracks produced in the detectors as a result of 235U (n, f) reaction were counted under an optical microscope. The uranium concentration was determined by counting and comparing the observed fission track density in the samples and the standard. The observed uranium concentration in the studied water samples varied from (1.04 ± 0.30) μg·L-1 to (21.08 ± 2. 95) μg·L-1 with an average value of (7.39 ± 1.30) μg·L-1 and is found to be within safe limits as far as uranium related health hazards are concerned.展开更多

Because of the growth of coal mining, coal-fired power plants and coal-burning industries, the increase of the emission of particulates(coarse, fine or ultrafine)is of great concern. There is a relationship between increasing human morbidity and mortality and progressive environmental air pollution caused by these types of particles. Thus, the knowledge of the physico-chemical composition and ambient concentrations of coal-derived nanoparticles will improve pollution control strategy. Given the current importance of this area of research, the advanced characterization of this coal combustion-derived nanoparticles/nanominerals as well as hazardous elements is likely to be one of the hottest research fields in coming days. In this review, we try to compile the existing knowledge on coal-derived nanoparticles/nanominerals and discuss the advanced level of characterization techniques for future research. This review also provides some of aspects of health risks associated with exposure to ambient nanoparticles. In addition, the presence of some of the hazardous elements in coal and coal combustion activities is also reviewed.展开更多

Irregular growth in children can lead to many health hazards ranging from physical impairment to death. In Sierra Leone, poor Infant and Young Child feeding practices are predominant, with only 32% of children being exclusively breastfed and 42% appropriately fed with complementary foods, some of which are produced home-made. This study aimed to assess the quality of home-made produced baby foods and their impact on the health of infants. The objectives of the study are to, 1) investigate the weaning process and identify the types of food mothers/caregivers use to introduce the child to weaning food, 2) interview parents in the community that feed their children with home-made produced baby foods to understand, the health and developmental problems affecting their children in relation to the food, 3) observe and assess the production and processing methods of home-made produced baby foods and 4) relate these processes to the quality of the food and analyse home-made produced baby foods. Using laboratory techniques the food quality and possible contamination were assessed and possible amendments for the benefit of the child were suggested. Interviews were conducted using a structured interview schedule and food was analysed in the laboratory for macronutrient levels, and microorganisms. It was discovered that babies are introduced to weaning foods before three months and 100% both production and preparation observed have the tendency to contaminate the food. Not all the food tested have the required levels of nutrients. Microorganisms that can be pathogens were found in the food. It was concluded that home-made produced foods are often not safe weaning foods since they have the potential to cause food borne in children.展开更多

These hazards include exposure to biological and non-biological hazards like ionizing radiation, stress, injury, infectious agents, and chemicals. The aim of this study was to assess common occupational hazards among health workers at the Department of Health Services (DHS), Federal University of Technology, Owerri. Methods: A hospital-based cross-sectional study design was employed for the study, and a self-administered questionnaire was used for data collection. The SPSS Version 22.0 software was used for the analysis of the descriptive statistics obtained from the study. This study included both clinical and non-clinical health workers. A purposive sampling technique was used in recruiting a total of 94 respondents who participated in the study from September 2020 to April 2021. Results: A total of 94 respondents who participated in the study and among the participants, 33.3% (31) of the respondents were aged 31 - 40 years, and the majority of the health workers, 43.6% (41) had stayed between 1 - 5 years. Also, 92.6% (87) of the health workers have heard of occupational hazards. The study showed that 84.0% (79) of health workers had good knowledge of common occupational hazards. Biological hazards among health workers are 47.9% (45) cuts and wounds, 29.8% (28) direct contact with contaminated specimens/hazardous materials, and 26.6% (26) sharp related injuries, while for non-biological hazards, 44.7% (42) have slipped, tripped or fallen, and 35.1% (33) have been stressed. Common safety measures include 86.2% (81) washing their hands regularly;78.7% (74) using hand gloves;and 85.1% (80) agreeing they use face masks. Conclusion: Despite good knowledge of occupational hazards, participants at DHS were faced with certain hazards. It is recommended that the university, government, and policymakers revise and implement actions to provide health workers at DHS with equipment to encourage safety in work activity.展开更多

In addition, human diet is evolving with a decreased inclusion of proteins from animal sources. In this context, consumption of insects by humans (entomophagy) could be an alternative solution to the intake of protein derived from conventional livestock, due to the lower environmental impact of insect rearing compared to traditional farming. Furthermore, various insect species have promising nutritional profiles regarding both macro and micronutrients. Nowadays, it is recognized that about 2 billion people consume insects at a worldwide scale, with more than 2000 different species to have been reported. Since the beginning of the 2000s, mass rearing of insects for human consumption has been developing all over the world. Nevertheless edible insects are foodstuffs of animal origin and are usually consumed in their entirety, including the digestive tract, meaning that they may contain biological agents with hazardous potential (e.g. bacteria, parasites, viruses, prions, yeasts, molds, mycotoxins, histamine, and antibiotic resistance genes) and they must undergo a thorough analysis. Therefore, establishing the synthesis of the current knowledge on entomophagy and the related biological hazards is the main purpose of this review.展开更多

The study sought to assess and evaluate occupational health and safety hazards experienced among health workers in the Bono region of Ghana. METHODOLOGY The study was descriptive cross-sectional quantitative study. Data was from two hundred (200) health workers and was analyzed using the binary logistic regression analysis. RESULTS The findings from the study show that risk factors associated with biological hazards were clinical staff [OR = 2.487 (1.146 - 5.397), p = 0.021], poor maintenance of hospital items [OR = 0.446 (0.240 - 0.831), p = 0.011], assault (verbal) abuse [OR = 2.581 (1.317 - 5.059), p = 0.006] and extreme pressure from work [OR = 2.975 (1.519 - 5.829), p = 0.001]. Non-biological hazards were associated with being single [OR = 0.499 (0.263 - 0.947), p = 0.034], being verbally assaulted [OR = 3.581 (1.865 - 6.876), p CONCLUSION Risk factors related with biological hazards include poor maintenance of hospital items and extreme pressure from work whereas non-biological hazards were associated with being single, being verbally assaulted. Clinical healthcare providers are more vulnerable to occupational health and safety hazards. The study recommends the provision of strategic policies to promote and protect the workers’ health based on the development of the epidemiological profile of health, needs to be readjusted and strengthened.展开更多
