Determination of naproxen, ibuprofen and triclosan in wastewater using the polar organic chemical integrative sampler (POCIS): A laboratory calibration and field application
In this study, the occurrence in wastewater of two non-steroidal anti-inflammatory drugs (NSAIDs), naproxen and ibuprofen, and one personal care product, triclosan, was assessed using the polar organic chemical integrative sampler (POCIS). The samplers were initially calibrated in the laboratory to obtain sampling rates (Rs) for each target compound followed by deployment in the influent and effluent of Goudkoppies and Northern Wastewater Treatment Plants (WWTPs), South Africa. Exposure was done for 14 days in 2012. High performance liquid chromatography (HPLC) system with ultraviolet (UV) and fluorescence (FLD) detectors was used to analyse POCIS extracts. Laboratory calibration of POCIS yielded Rs values for the three compounds that were between 0.087 and 0.383l.d-1 in quiescent conditions, and 0.125 and 0.936 l.d-1 in stirred conditions. From the accumulated amounts in field-deployed samplers, estimated freely dissolved concentrations of the studied compounds in wastewater influent ranged from 55.0 to 78.4 µg.l-1 and 52.3 to 127.7 µgl.-1 in Goudkoppies and Northern WWTPs, respectively. Average concentrations of these compounds in the treated effluent ranged from 10.7 to 13.5 µgl.-1 in Goudkoppies WWTP, and 20.4 to 24.6 µgl.-1 in Northern WWTP. Analyte removal efficiencies varied between 68 and 86% in Goudkoppies WWTP and 61 and 82% in Northern WWTP. Grab samples processed by SPE method yielded higher analyte concentrations (up to three-fold) as compared to POCIS-derived estimates. This discrepancy was attributed to SPE's ability to extract both the free dissolved, and particle sorbed fractions of the contaminants.Keywords: Polar organic chemical integrative sampler, pharmaceuticals and personal care products, wastewater, wastewater treatment plant
The Nexus between School-Related Factors and Boy-Child Participation and Retention in Public Secondary Schools: Lessons from Baringo County, Kenya
In many developing countries, the participation of the boy-child in education is characterized by low retention and poor performance and Baringo County, Kenya, is no exception. The problem of increased secondary school dropouts among the boys is a concern to educationists and the general public in Baringo County. The boy child in Baringo County is endangered due to low retention and participation in secondary education. To find ways of mitigating against the vagaries of such an unfortunate scenario, a study was carried out with an aim of establishing the relationship between school-related factors and boy-child participation and retention in public secondary schools education in Baringo County. The discussions in this paper are anchored on the findings of the study. Guided by selected tenets of the education production function theory, the study adopted a pragmatic world view and had a sample size of 573 participants comprising form three boy
Investigating the temporal trends in PAH, PCB and OCP concentrations in Hartbeespoort Dam, South Africa, using semipermeable membrane devices (SPMDs)
The seasonal variability of persistent organic pollutants in Hartbeespoort Dam, South Africa, was investigated using semipermeable membrane devices (SPMDs) as passive samplers. Freely dissolved waterborne polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs) and organochlorine pesticides (OCPs) were sampled to investigate seasonal changes in their concentrations. Exposure of the passive samplers was done for 14 days at the same sampling site in each of the four seasons of the year, in 2011. The SPMD-derived analyte amounts enabled the calculation of time-weighted averages of free dissolved waterborne levels of the contaminants. Concentrations ranged from 30.0 ng·l-1 to 51.5 ng·l-1 for PAHs, 38 pg l-1 to 150 pg·l-1 for PCBs, 9.2 to 10.4 ng·l-1 for HCHs and 0.3 to 0.8 ng·l-1 for DDTs, respectively. It was also noted that the winter season generally exhibited higher contaminant concentrations for most compounds studied, which likely reflects the seasonality of their atmospheric deposition. An attempt was also made to identify possible sources of PAH contaminants in the dam by examining PAH ratios. These diagnostic ratios were inclined towards pyrogenic sources of pollution, except for the winter season where both pyrogenic and petrogenic sources likely contribute to the contamination pattern.Keywords: Hartbeespoort dam, persistent organic pollutants, semipermeable membrane devices, water-dissolved concentrations, temporal trends
RELATIONSHIP BETWEEN COMMUNICATION COLLABORATIONS AND PERFORMANCE OF SMES IN TRANS-NZOIA COUNTY, KENYA
This papers looks at the relationship between communication collaborations and performance of SMEs in Trans-Nzoia County, Kenya. This was done due to the challenges that individual are facing in surviving in business. SMEs enter strategic collaboration to access to provide access to information necessary for their business growth and survival. The theory that informed this study is resource based view theory advanced by Barney. A descriptive research design was used to select 136 SMEs from a target of 216 located in Trans-Nzoia County, Kenya. Data for this research was collected using questionnaire. Correlation statistics showed that there existed significant positive relationship between strategic communication and performance of SMEs in Trans-Nzoia County. This happened through sharing of information or viability of business enterprises through the formal collaborating networks by SMEs in the county. The paper concludes that for performance of SMEs to improve, joint communication and sharing is a critical component. The paper therefore recommends that: the communiqué on decision reached by strategic collaboration members should all be inclusive to make all members feel part of the association.

Passive samplers : development and application in monitoring organic micropollutants in South African water bodies and wastewater
Annually, the global environment receives enormous amounts of persistent organic pollutants (POPs) that include polychlorinated biphenyls (PCBs) and organochlorine pesticides (OCPs), in addition to polycyclic aromatic hydrocarbons (PAHs). Their ubiquity has made them identifiable contaminants in almost every environmental compartment of the global system. In particular, aquatic systems have been adversely affected by these pollutants. Therefore, effective monitoring, both in ground and surface water, that can reliably assess their environmental impacts is required. Passive samplers have been proposed as suitable options to the traditional grab/spot/bottle sampling approach because they simultaneously sample, isolate and enrich target analytes. Moreover, apart from successfully detecting very low water dissolved analyte concentrations (trace and sub-trace levels), the devices can also provide time weighted average (TWA) concentrations that take into account episodic events. This is usually not practical with other sampling techniques
