Opis:
This study explores factors affecting facilities’ compliance to environmental regulations. The objectives were to: examine operator’s knowledge of environmental legal requirement of the facility, identify factors affecting environmental compliance and determine relationship between facility and environmental regulators. Systematic random sampling was used in selecting facilities, while purposive random sampling was adopted in selecting respondents from each facility. Simple random sampling was employed in selecting respondents from the regulatory agencies. The instrument for data collection from the respondents is a semi-structured set of questionnaires each for facility and regulators respectively. The questionnaire was administered to one hundred and twenty (120) respondents drawn from eight (8) facilities in different sectoral groups, while one hundred and sixteen (116) were administered to the regulatory agencies (NESREA and NISEPA). Findings shows that challenges militating against compliance to environmental regulations in the area include: the relationship between the regulatory agencies and the facility operators as reported by 22.9% of respondents who upheld that there is fairly relationship between the facility operators and the regulatory agencies. More so, the singled most influential factor is lack of awareness of the regulations (52.5%). Consultation between the environmental regulators and the facility operators prior to the introduction of any environmental regulation is a factor in environmental compliance as reported by 37.6% of the respondents (facility operators) who maintained that they are not consulted before introducing any environmental regulation. It is recommended among others that every facility operator should be considered as a stakeholder in drafting environmental regulations. Exclusion of them is tantamount to low level of compliance as they will claim not to be aware of the regulations. Also, there is need to consistently create environmental awareness among the facility operators and the general public in order to become environment conscious and uphold environmental sustainability.

Opis:
This cross-sectional study assessed Nigerian Physiotherapy students’ knowledge, attitudes and awareness of the roles of physiotherapy in the prevention and management of COVID-19.  Four hundred (400) Nigerian physiotherapy students responded to the survey via an electronic (WhatsApp) questionnaire. The survey revealed a high degree of COVID-19 awareness (98.3%) with the social media (83.3%), especially WhatsApp (70.8%), indicated as the. main source of information. 52% of the respondents exhibited a good level of knowledge of the virus, as well as anti-COVID-19 precautions and hygiene. The level of knowledge correlated with the participants’ ages; the final year (class v) had the highest knowledge score (40). While Nigerian physiotherapy students demonstrate a high level of awareness with regard to the virus and its transmission, the level of knowledge relating to physiotherapy roles in COVID-19 appears to be low.

Opis:
This research analysed livelihood diversification and income in resident communities along the Kiri Dam, Adamawa state, Nigeria. The specific objectives of the study were: to describe the socio-economic characteristics of the respondents, assess the level of livelihood diversification of the respondents, analyse income of the respondents, identify factors associated with varying levels of income, and identify constraints to livelihood diversification in the area. A multistage sampling technique was used to collect primary data from 120 respondents from the study area. The data collected were subjected to descriptive and inferential statistical analysis. The results showed that the majority of the respondents were male (78%), married (76%), educated (70%), below 60 years of age (93%) and employed in agricultural activities (83%). The Simpson index of diversification shows that 43% of the respondents diversify at an average level. The majority (60%) of the respondents’ annual income is over ₦ 200,000. The ordinary least square estimation shows that age, marital status, education, irrigation activities, fishing, farm size and level of diversification affect income level in the area. The main constraints to diversified livelihood in the area were a lack of basic social infrastructure, a hippopotamus menace and flooding. The study recommended the provision of social infrastructure and the control of hippopotamuses.
W niniejszym artykule przeprowadzono analizę zróżnicowania źródeł utrzymania oraz poziomu dochodów społeczności zamieszkujących przy zaporze Kiri w stanie Adamawa w Nigerii. Szczegółowe cele badania to: określenie socjoekonomicznego profilu respondentów, ocena poziomu różnorodności źródeł ich utrzymania, analiza dochodu, identyfikacja czynników wpływających na poziom dochodów oraz identyfikacja ograniczeń w zróżnicowaniu źródeł utrzymania na badanym obszarze. Na potrzeby pozyskania danych podstawowych od 120 respondentów posłużono się techniką doboru wielostopniowego. Zgromadzone dane poddano opisowi oraz wnioskowaniu statystycznemu. Przeprowadzone analizy wykazały, że większość (78%) respondentów to mężczyźni, osoby pozostające w związku małżeńskim (76%) i wykształcone (70%). Aż 93% badanych miało poniżej 60 lat i zajmowało się rolnictwem (83%). Wskaźnik Simpsona wykazał, że 43% respondentów charakteryzowało się różnorodnością na poziomie przeciętnym. Roczny dochód większości (60%) respondentów wynosił ponad 200 tys. ₦. Oszacowanie klasyczną metodą najmniejszych kwadratów wykazało, że wiek, stan cywilny, wykształcenie, działalność w zakresie nawadniania i rybołówstwa, wielkość gospodarstwa oraz poziom różnorodności wpływały na poziom dochodu na badanym obszarze. Głównymi ograniczeniami zróżnicowania źródła utrzymania były: brak infrastruktury społecznej, szkody wyrządzane przez hipopotamy oraz powodzie. Zaleca się zapewnienie odpowiedniej infrastruktury społecznej i opanowanie zagrożenia ze strony zwierząt.

Opis:
Background. Natural spices are commonly used by the people in Nigeria. They may be easily contaminated with heavy metals when they are dried and then pose a health risk for the consumers. Objective. The aim of this study was to determine the levels of heavy metals in some commonly consumed natural spices namely Prosopis Africana, Xylopia aethiopica, Piper gineense, Monodora myristica, Monodora tenuifolia and Capsicum frutescens sold in the local markets of Awka, Anambra state, South East Nigeria to estimate the potential health risk. Results. The range of heavy metal concentration was in the order: Zn (14.09 – 161.04) > Fe (28.15 – 134.59) > Pb (2.61 – 8.97) > Cr (0.001 – 3.81) > Co (0.28 – 3.07) > Ni (0.34 – 2.89). Pb, Fe and Zn exceeded the maximum allowable concentrations for spices. The Target Hazard Quotient (THQ) of the spices varied from 0.06 – 0.5. Estimated daily intakes (EDI) were all below the tolerable daily intake (TDI). The lead levels in Prosopis africana, Xylopia aethiopica, Piper gineense, Monodora myristica and Capsicum frutescens which are 8-30 times higher than the WHO/FAO permissible limit of 0.3 mg/kg. Conclusions. Lead contamination of spices sold in Awka (south east Nigeria) may add to the body burden of lead. A good quality control for herbal food is important in order to protect consumers from contamination.

Introduction and objective. For an effective and desired outcome of therapy to be achieved, the technical capacity of the healthcare worker is a key factor. The aim of the study is to assess knowledge and attitudes of primary healthcare (PHC) workers towards rational artemisinin-based combination therapy (ACT) prescribed in the treatment of uncomplicated malaria. Materials and method. This is a descriptive cross-sectional survey in which a self-administered structured questionnaire was used. A combination of stratified and multistage sampling techniques where utilized in the selection of the healthcare workers (HCWs). Results. Of the 422 respondents, 100 (23.7%) were males and 322 (76.3%) were females. Respondents with less than five years in practice accounted for 36%, while 64% had six years and above of practice. Community health extension workers (CHEW) accounted for 54%, while 46% were either community health officers (CHO), nurses, midwives, Bachelors of Science (BSc) in community health, or with other qualifications. A total of 390 (92.4%) were aware of the availability of ACTs and used the malaria treatment protocols, whereas 28 (6.6%) still used monotherapy for simple malaria treatment, and 2.7% did not use any form of test before initiating treatment. Co-administration of non-ACTs with ACTs accounted for 12%, with 88% prescribing paracetamol with ACTs. 67% of the respondents required capacity building in rational ACT use. Conclusion. The majority of the respondents had the requisite knowledge and skills coupled with positive attitudes in prescribing ACTs. Some respondents could not distinguish between an ACTs and a monotherapy. This may affect the exact application of the malaria treatment protocols, especially at the PHC level.

Background. The belief that Chinese teas are of immense health benefits by many Nigerians has led to high consumption rate. Objectives. This study has determined lead and polycyclic aromatic hydrocarbons (PAHs) levels of Chinese teas popularly consumed in Nigeria and to estimate the potential health risks. Material and Methods. Twenty brands of Chinese teas commonly consumed in Nigeria purchased in October 2014 were used in the study. Tea samples were extracted and digested. Lead, and PAHs were analyzed using an atomic absorption spectrophotometric (AAS) and gas chromatographic methods, respectively. Daily intake, percent violations of permissible limits, target hazard quotients (THQ), Health Risk Index (HRI) of lead, and other cancer risk parameters of PAHs were estimated. Results. All the tea samples except super natural green tea violated the WHO permissible limit of lead (0.01 mg/kg) by over 100%. The HRI ranged from 5.09 x 10-5 – 7.20 x 10-4 . Among the single analyzed compounds, the pyrenes had the highest concentration of 14.31 mg/kg. The intake of benzo[a]pyrene was detected in 25% of the samples which ranged from 0.066 to 0.145 mg/kg and exceeded the permissible daily limit of benzo[a]pyrene intake. The estimated cancer risk from this study in an adult is 5.07 x 10-9. Conclusion. The present study suggests that consumption of Chinese teas in Nigeria may not be one of the factors responsible for the increased rate of cancer in Nigeria.

Background. Toothpastes have multi-functional configurations as oral care products. They can however constitute a possible source, amongst others, of toxic metal exposure in public health. Indeed, the public health impact of personal hygiene and consumer products is largely unknown. Objective. To determine the level of toxic metals (lead, cadmium, cobalt, chromium, nickel) in toothpastes available in Nigeria, (home produced and imported), and assess the potential risk to the people. Material and Method. The samples of toothpastes commonly used in Nigeria were tested. Using a market basket protocol thirty five different brands of toothpaste were used. Samples were digest by addition of 10 mL mixture of conc. nitric and hydrochloric acids (HCl:HNO3, 3:1), followed by heating to dryness. 20 mL deionized water was added, stirred and filtered. The filtrate was made up in standard volumetric flask and lead, cadmium, chromium, cobalt and nickel concentrations were determined using the atomic absorption spectrophotometry 205A. The daily intake of metals and target hazard quotient (THQ) were then calculated. Results. Pepsodent and Flodent had the highest levels of lead at respectively 23.575 and 18.092 mg/kg while Colgate Herbal had the highest nickel of 18.535 mg/kg. The daily intake estimates of all imported toothpaste samples were below the stated upper limits (UL). All target hazard quotients were also found to be below one. Conclusions. Although the UL, THQ and daily intake rates were all normal, the high levels of lead in some of the toothpastes an important concern to public health suggesting that pre-marketing safety studies of toothpastes may be worthwhile for the regulatory authorities.

Opis:
The study of tree-hole breeding mosquitoes was carried out in the tropical rainforest of Imo State Nigeria (two rural areas and two forest reserves in some parts of Orlu Senatorial Zone) between May – October 2002. Using standard entomological procedures, two macrohabitats (natural tree-holes and bamboo traps) and two microhabitats (leaf axils of cocoyams/pineapples and leaf axils of plantain/banana) were sampled for various mosquito species. Mosquitoes were recovered from all the various biotypes sampled. Types of mosquitoes species encountered, their relative abundance, as well as genera varied signifi cantly during the study (p<0.05). Four genera of mosquitoes: Aedes, Culex, Anopheles and Toxorhynchites were recovered while 16 species of mosquitoes encountered include: Aedes aegypti, Ae. africanus, Ae. simpsoni, Ae. albopictus, Ae. stokesi, Ae. taylori, Ae. apicoargenteus, Culex quinquefasciatus, Cx. nebulosus, Cx. trigripes, Cx. decens, Anopheles gambiae, An. funiestus, An. coustani and Toxorhynchites viridibasis. Most of the mosquitoes showed oviposition preferences for one or more habitats. The presence of Ae. africanus, Ae. simpsoni and Ae. aegypti indicate that the study areas were at risk of yellow fever epidemic. The presence of Anopheles and Culex species ensured endemicity of malaria and fi lariasis, while the recovery of Ae. albopictus in this region suggests a possible outbreak of dengue fever in future if not properly controlled.
