This study examines the responses of zoos and bushmeat markets in Lagos State, Nigeria, to pandemic challenges and assesses the effectiveness of their post-pandemic strategies. Research was conducted at three sites in Lagos; Shodex Zoo Garden, Omu Resort Zoo, and Epe Wildlife Market, a hub for bushmeat trade. Data were collected using 150 semi-quantitative questionnaires distributed among bushmeat traders and zoo staff: 50 at Epe Wildlife Market and 100 among zoo staff and visitors at the two zoos. The survey evaluated the impact of the pandemic on animal welfare, zoo operations, and the bushmeat trade. Before the pandemic, zoo animals were in excellent condition, but during the pandemic, their condition deteriorated due to reduced food supplies, medical care, and veterinary services. Zoos suspended visitor access, enhanced hygiene protocols, and made dietary adjustments, but veterinary care was insufficient. Seventy-two percent of zoo staff reported increased illness among animals, primarily due to loneliness and depression. Post-pandemic, the effectiveness of these measures varied. Visitor behavior changed little, with 64% of respondents reporting no significant change in visitation frequency. The bushmeat trade faced significant disruptions due to movement restrictions and decreased demand but rebounded post-pandemic, returning to pre-pandemic levels. The study highlights the need for zoos to adopt more robust practices for future pandemics. The Study recommends  improving zoo conditions, promoting sustainable ecotourism, enforcing stricter bushmeat trade regulations, increasing public education, and supporting alternative livelihoods to reduce reliance on illegal wildlife trade. Collaborative efforts among conservationists, governments, and local communities are crucial for effective wildlife protection.","PeriodicalId":166614,"journal":{"name":"Open Journal of Environmental Research (ISSN: 2734-2085)","volume":"83 24","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141798501","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By using sawdust, a byproduct of the forestry industry, in the process of making concrete, the investigation addresses the pressing need for resource conservation and waste reduction, since the construction sector is a significant user of raw materials. According to British European Norm Standard BS 8500-2:2023 for C35 grade concrete, the experimental programme examines how different percentages of sawdust (0%, 5%, 10%, 15%, 20%, and 25%) substituted for sand affect the physical characteristics of concrete, including its compressive strength, dry density, and water absorption. The workability, consistency, and strength of the sawdust-incorporated concrete mixes were assessed by a combination of techniques including sieve analysis, slump testing, casting and curing procedures, and compression tests. The results indicate a potential reduction in material costs and environmental impact with the ideal sawdust content by showing a negative association between the amount of sawdust and the concrete's density and compressive strength. A larger sawdust content was associated with higher rates of water absorption, highlighting the hygroscopic nature of sawdust and its implications for the durability of concrete. According to the investigation's results, it is possible to substitute concrete with up to 5% sawdust, providing an environmentally friendly alternative to conventional concrete while still having sufficient mechanical properties for use in construction. It is recommended that further research be conducted to improve sawdust's compatibility with cementitious materials, increase the durability of sawdust-incorporated concrete, and create industry guidelines for its use. This investigation contributes to the body of knowledge on environmentally friendly building materials by promoting the use of sawdust and other eco-friendly substitutes in the building sector to reduce negative effects on the environment and increase resource efficiency.","PeriodicalId":166614,"journal":{"name":"Open Journal of Environmental Research (ISSN: 2734-2085)","volume":"35 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140974675","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Others are due to a natural craving. These practices are associated with varying health complications; as such, it is pertinent that the physical and chemical composition of the clay be known. In this study, we assessed the levels of heavy metals and trace elements of clinical importance in ‘Eko’, as well as their physical and chemical properties using standard protocols. Tests conducted include: colour, pH, electrical conductivity (EC), cation exchange capacity (CEC), total dissolved solids (TDS), particle density, and concentrations of metals [chloride (Cl), sulphate (S), calcium (Ca), sodium (Na), magnesium (Mg), potassium (K), aluminium (Al), iron (Fe), copper (Cu), manganese (Mn), zinc (Zn), chromium (Cr), lead (Pb) and cadmium (Cd)]. The results obtained showed that some of the elements (Cl, Ca, Na and Mg) are present in moderate concentrations (353.33, 182.33, 216, 111.33 mg/kg) respectively. However, concentrations of some of the heavy metals [(Cd, Pb and Cr) (0.30, 0.26, 0.42 mg/kg) respectively], were higher than the permissible limits (65, 35, 25 µg/kg) set by WHO. Though some of the moderately present trace metals may play important biological roles, the high concentrations of some heavy metals could have detrimental health effects. Results from this study suggest that ‘Eko’ can predispose consumers to health hazards. As such, the continuous consumption of “Eko” should be discouraged","PeriodicalId":166614,"journal":{"name":"Open Journal of Environmental Research (ISSN: 2734-2085)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123568625","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The impacts of human carbon footprints induced climate change on health and the economy are been published widely in the literature. This review succinctly x-rayed the impact of human carbon footprints on public health and the economy within the African context. The relationship between carbon footprint and public health was conceptualized as continuous cyclic interaction, continuously bringing woes to mankind. Carbon footprint impact on public health was presented to be in two ways – directly or indirectly. The direct impact of carbon footprints on public health was explored under five (5) thematic areas,  which are: impact on extreme weather events (hurricanes, storms, and floods), impacts on temperature, impacts to air pollution, impacts to water- and foodborne diseases,   and impacts to vector and rodent-borne diseases. The impact of a carbon footprint on the economy was seen as an indirect impact on humans and a huge change in human lives.

Physical and chemical parameters found to affect the interactions and mobility of heavy metals in the soil mass were also examined. A pH of 6.17±0.2 was obtained for the topsoil while the middle and bottom soil samples were 5.93±0.4 and 6.00±0.1 respectively, The values of CEC obtained for top, middle, and bottom soil samples were 5.58±0.54, 4.56±0.11, and 3.65±0.14 meq/100g respectively. Soil samples were randomly collected from three depths of 0-10 cm, 10-20 cm, and 20-30 cm with the aid of a soil auger; and T. triangulare were collected within the soil sampling locations. The concentrations of heavy metal were evaluated through the use of atomic absorption spectrophotometer after the samples were subjected to tri-acid digestion techniques. Particle size analysis showed that the soil is a sandy loam texture. High Transfer factor values were ascertained for some metals but none was greater than one. Therefore T. triangulare cannot be considered a hyperaccumulator of heavy metals investigated in this study. However, all metals found in T. triangulare were highly significant (p<0.05), and higher than the permissible limits recommended by FAO/WHO/EC/CODEX. Consumption of T. triangulare harvested from the vicinity of automobile workshops should be highly discouraged to avoid public health hazards.","PeriodicalId":166614,"journal":{"name":"Open Journal of Environmental Research (ISSN: 2734-2085)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123993504","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study aimed at evaluating the perception and vulnerability of   Ibeju-Lekki and Eti Osa Local government areas to climate change; to introduce effective climate change  awareness, mitigation, and adaptation techniques. The study was carried out through field surveys, questionnaire administration, Personal interviews, and Focus Group Discussions (FGD). The data collected were analysed using the Statistical Package for Social Scientists (SPSS). The study showed that on average, the sampled coastal communities  recorded climatic changes in their environment, but they have not been able to account for the factors that  initiated these changes. The human dimension to climate change is missing in their perception. This relates to how their activities contribute to climate change. The coastal area is highly susceptible to coastal activities that have been exacerbated by climate change. Therefore, given their perception and high vulnerability, there is an urgent need for climate change awareness in the study area to prepare the communities through enlightenment campaigns and to build their adaptive capacity. This study, therefore, recommends that government should intensify its climate change awareness drive until all and sundry are sufficiently sensitized to   contribute meaningfully in mitigation and adaptation measures. In tackling the challenge of climate change in coastal areas of Lagos State, emphasis should be given better preparedness, adaptation strategies that are low-tech particularly those that are targeted at the most vulnerable members of the society and communication/awareness techniques.","PeriodicalId":166614,"journal":{"name":"Open Journal of Environmental Research (ISSN: 2734-2085)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126304788","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, peatland carbon is mostly stabilized in humic fractions where it forms complexes with metallic elements. This study sought to measure the levels of dissolved organic carbon (DOC) in rivers and analyze the link between physicochemical parameters and humic fractions along the Buhandanda and Lushala peat profiles. Inductively-Coupled Plasma Optical Emission Spectrometry, chemical fractionation followed by sulfochromic oxidation, and dosing by indirect chemical oxidation were used to determine major geochemical elements (MGE), humic fractions (HS), and DOC, respectively. Average MGE concentrations were 4.1±1.4, 3.6±0.5, 2.8±0.6, 1.8±0.7, 1.1±0.4, 0.3±0.1, 0.1±0.0, 0.5±0.3, 0.1±0.0, 0.03±0.0, 0.03±0.0 and 1.9±0.9, 3.6±0.8, 2.5±0.6, 2.0±0.5, 1.1±0.4, 0.3±0.0, 0.09±0.01, 0.18±0.1, 0.06±0.04, 0,02±0.0 for Ca, Fe, Si, Al, S, Ti, K, Mg, Mn, Na for Lushala and Buhandanda, respectively.

FA was also higher than HA for Lushala peat except for depths 20, 90, 140, and 200 cm. Humin (HU) was the highest fraction on the two peatlands. Humification index (HI) and degree of transformation (DT) of HS had values of the same order of magnitude (from 0.32 to 2.43). No association was found between physicochemical properties and HS, except for FA and Fe, Ca, S, Mg, Mn, Se on Lushala peat. DOC showed a downward trend from entry to exit of peatlands.

Lagos State, for example, is one of Nigeria's emerging urban states, with a dense population, rapid urbanization, and a rapid rise of the middle class over the last decade. Lagos state's growing human population, economic progress, and urbanization have exacerbated waste management and generation issues.

This is especially important in developing countries like Nigeria, where there are no strong institutionalized frameworks for waste management, and as a result, increasing waste poses a threat to human well-being. Given the increase in population in these countries, it is necessary to adopt sustainable and practical solutions. Especially in Lagos, where the environmental problem of plastic waste is on the rise. Although the government is making commendable efforts to reduce the increasing volume of plastic waste in the state, they are insufficient, as it has been reported that plastic waste accounts for 15% of total waste volume according to the Lagos state waste characterization index. However, with the rise in various environmental problems caused by plastic waste, this paper proposed combining the extended producer responsibility (EPR) and deposit refund system (DRS) to achieve a high rate of recovery and recycling of waste plastic bottles and sachets. The innovative approach used green technology (vending machine) as well as indigenous knowledge are practical solutions in Lagos state.
