“…A significant increase in human settlement particularly in the urban areas had put many people vulnerable to firerelated disasters. According to Adamu et al (2020), many disasters are occasioned by the rapid population growth rate, urbanization, and socio-political issues occasioned by ethnic plurality, which all, in turn, create fierce competition for national resources, that result in deteriorating livelihoods, social marginalization, crime, and general insecurity. Another opinion by Yunus (2021), that population growth and urbanization have led to over-stretching of the land and existing infrastructures as a result of an increase in human activities (social, economic, and political), demand for land, services, and basic amenities, and market places are not exceptional.…”

Fire has been a source of energy for the human population throughout the history. With the growing urban population in Nigeria, city infrastructures are under pressure. Markets particularly in most Nigerian cities are over congested due to poor planning and illegal allocation of space for shops. Previous experience reveals that whenever there is a fire outbreak in the market it becomes very difficult for firefighters to get access to quench as a result lives are lost and properties are destroyed. Data for this paper were collected from the Sokoto Central Market Management record containing nine major fire incidents since 1980. A sample of 134 purposively sampled respondents were collected and interviewed using a structured questionnaire. Data collected were subjected to simple descriptive statistics and inferential statistics specifically cross-tabulation. Major findings revealed that the careless attitude of shop owners 62.7%) was the main cause of the fire disaster while 55.2 % attested to the fact that the magnitude of damages was the result of the distortion of the market's master plan and 22%attributed it's to the lack of functional fire service facilities and inadequate manpower in the market. The major challenge faced by 56% of traders was the loss of customers who could not find them due to their temporary relocation. The study recommended that traders should be incorporated into the post-fire reconstruction of the damaged area so that the required number of shops will be adequately captured in the distribution process. Since the human factor is the cause of most fire disasters, the study further recommended that the Fire Service Department should organize regular sensitization, seminars on the causes, and emergency prevention measures for future recurrence.

“…Ogbonna et al, 2018 andAdamu et al, 2021).Liu et al, (2019) attributed differenc es in leaf morphology to adaptive features and the ability to withstand environmental factors such as serrated leaf margins which help to reduc e transpiration rate.Quantitative measurements showed significant variations in the amount of dust accumulated and leaf sizes (Table2). At both sites, N. latifolia and A. senegalensis had the largest leaf area while B. ferruginea had the smallest leaf area.…”

Plants are determinant of air quality and are useful in mitigating air pollution and biomonitoring of the pollution stresses. Present study assessed the effect of stone-mining dust accumulation on foliar parameters and air pollution tolerance index (APTI) of five plants (Annona senegalensis, Bridelia ferruginea, Ficus capensis, Nauclea latifolia and Protea madiensis) commonly growing around an artisanal stone-mining site at Eziani Nsukka and Botanic Garden of the University of Nigeria, Nsukka, the control. Dust load was estimated gravimetrically. The foliar analysis carried out on the epidermises was obtained by clearing method and studied under microscope and all photomicrographs were taken with Moticam Camera 2.0 attached to the microscope. Biochemical parameters and APTI were determine following standard methods. Dust accumulated on polluted plant leaves was high and resulted in distortion and deformation of the epidermal and guard cells. The cells appeared stretched and broken compared to the control plants. Quantitative stomatal indices such as length, width, size and density were also significantly affected by dust pollution. Polluted plants showed increase in ascorbic acid, reduction in pH values, relative water content and total chlorophyll content, and produced low tolerance index than the controls. Highest and lowest APTI were found in A. senegalensis and B. ferruginea. At polluted site, A. senegalensis had APTI (17.14 ± 0.24) and B. ferruginea had (11.38 ± 0.07) which differed significantly from the APTI of A. senegalensis (18.92 ± 0.24) and B. ferruginea (13.49 ±0.28) at the control site. A. senegalensis was the most tolerant to air pollution while other plants were intermediate tolerant plants. The abnormalities in artisanal stone-mining plants may be due to prolonged exposure to dust. However, ability of the plants to tolerate air pollution makes them potential good environmental cleaners and as such, are recommended as choice plants around stone-mining and dust-polluted sites for safer environments and better health of both miners and the inhabitants.
