ABSTRACT Global, regional and national production of Nile Tilapia (Oreochromis niloticus) has faced challenges of low yields and lack of crucial culture information. Farmers in Teso North Sub County recorded lower yields than expected in 2009 despite having been provided with inputs. Factors responsible for the low production had not been established and water quality was suspected to be among them. The purpose of this study was to assess the effects of water quality on the growth of Nile Til...
Abstract Aquatic pollution by heavy metals remains a recurrent problem globally due to their persistence, toxicity and ability to accumulate in biological systems. This study investigated the pollution trend, ecological and public health risks associated with heavy metal pollution in the Lagos Lagoon as well as pattern of interaction among heavy metals that can be exploited for remediation of exposed aquatic organisms. Heavy metal content in surface water, sediment and biota were analyzed us...
ABSTRACT The ever increasing levels of electronic waste (e-waste) and limited capacities for disposal and recycling have worsened e-waste management considering only 10% of e-waste is properly managed globally. In developed countries, e-waste management is guided by extended producer responsibility frameworks that ensure e-waste collection and recycling through consumer participation whereas, in Asia and Africa e-waste is managed through inefficient solid waste systems resulting to degradatio...

ABSTRACT The honeybee (Apis mellifera L.) produces honey and cross pollinates plants for improved socioeconomic wellbeing. However its colony populations globally and locally have been declining. In Transmara West Sub-county, hive colonization and honey yields have been low, which is due to the decline in honeybee population believed to be caused by pesticides use and pests attack. Although their relative contributions are unknown, Beekeepers suspect pesticides use hold a key role in colony p...
ABSTRACT Quarry mining produces substantial dust amounts bearing an adverse effect on human health in several ways, mainly the respiratory system. Even though employers are obligated to protect their employees from occupational hazards, the quarry mining industry in Namibia has failed to honour that obligation. This study investigated quarry workers and the surrounding community’s exposure to dust as well as their risk of getting chronic respiratory diseases in the Erongo region of Namibia....
ABSTRACT Introduction Tuberculosis and diabetes mellitus are public health challenges globally. The World Health Organization (WHO) Global report on diabetes reiterated that diabetes is a well-known risk factor for tuberculosis (TB) and that diabetes is associated with poor tuberculosis treatment outcomes, while tuberculosis is linked with deteriorating glycemic control. Namibia is among the top 30 high TB burden countries in the world (WHO, 2016) and added to that is the increasing prevalenc...

ABSTRACT BACKGROUND: Escherichia coli (E. coli) is a bacterium that can asymptomatically colonize a woman’s vagina and up to 31% of pregnant women are colonized worldwide. Furthermore, vaginal colonization with E. coli is associated with adverse pregnancy outcomes, such as preterm birth and stillbirth. It is also associated with neonatal sepsis or meningitis when transmitted to the foetus through amniotic fluid or to the neonate during delivery. To date in Namibia data on the colonization a...
