“…Cassava is typically used as food in the form of gari, lafun and fufu, livestock feeds, confectionaries, sweeteners production Adebayo-Oyetoro et al, 15 additives to several pasteries such as bread cookies, biscuits and rolls, doughnut, cakes, flakes etc especially in private house hold level Emurotu et al 1 Beside food, cassava have also found application in several sector including glues, textiles, pharmaceuticals Adebayo-Oyetoro et al 15 and bioethanol production Ukwuru & Egbonu et al 14 Cassava is a tuber crop that is propagated by stem. [16][17][18][19] According to Izah & Aigberua,20 cassava matures between 6-12 months of planting depending on the variety. The authors further reported that the utilization rate of cassava vary according to the income size and source of income of the farmer especially in the rural area.…”

Health risk assessment of selected heavy metals in gari (cassava flake) sold in some major markets in Yenagoa metropolis, Nigeria Submit Manuscript | http://medcraveonline.com MOJ AbstractGari (cassava flake) is a major staple food in Nigeria. It's also a major source of energy food to several families. This study evaluated the health risk assessment of selected heavy metals in gari sold in some major markets in Yenagoa metropolis, Nigeria. Triplicate gari sample were obtained from four different markets in Yenagoa metropolis, Nigeria. The samples were ashed, digested and analyzed using atomic adsorption spectrophotometer. Health risk assessment was carried out using target hazard quotient, health risk index and daily intake index. Result revealed that the heavy metals concentration ranged from 1.32-3.81 mg/kg (manganese), 2.21-5.66 mg/kg (zinc), 1.00-3.72 mg/kg (copper) and 11.16-38.75 mg/kg (iron). There was significant difference (P<0.05) in each of the heavy metals among the various locations. The target hazard quotient and health risk index values were <1. This indicates no potential health risk of the studied heavy metals in the gari among the population under study.Citation: Kigigha LT, Nyenke P, Izah SC.

“…The correlations matrix of the various parameters under study for waste dumpsite is presented in Table 6. There was high significant relationship between the noxious gases (nitrogen dioxide, Sulphur dioxide, carbon monoxide, hydrogen sulphide, ammonia suggesting that the emissions are from similar source (Izah et al, 2017b). Furthermore in some instances meteorological factors had effect on emissions.…”

“…Based on this, geometric mean was used as reference which have been considered for assessing environmental risk (Bhutiani et al, 2017;Thambavani and Uma Mageswari, 2013) and median value which has been recommended by Bhutiani et al (2017), Monakhov et al (2015), Sarala and Sabitha (2012). Typically, the use of median which is a measure of central tendency in place of arithmetic mean shows the main trend in the index values for management purpose (Izah et al, 2017b;Sarala and Sabitha, 2012). As such the risk assessment for this study was based on two scenarios viz geometric and median means.…”

Weather is a global phenomenon caused by the unequal amounts of solar energy reaching the tilting earth's surface creating pockets of warm and cold air around the earth. The resultant difference in air temperature and pressure causes warm air to rise and cold air to sink creating wind which gives rise to variation in weather conditions around the planet. Weather is never stable. It varies over time and space. The same is true for climate, which is the average weather condition over a place and over a period of time. This brings about seasons. Seasonality in climate/weather is a major factor in the socioeconomic and political life style considerations of any nation. In Temperate regions, four seasons are recognizable: Summer, autumn, winter and spring while in Tropical regions like Nigeria two main seasons, dry and wet periods are predominant. The climatic features and variation in any region can be understood in terms of the various weather zones which constitute the major modules of the climate that are peculiar to the region, for instance in Nigeria harmattan (dry but humid weather) the steady rain and drizzle, the uproar line thunderstorms and the little dry season (Adejuwon, 2011). Adejuwon (2011), Ayoade (1974) reported that the various occurrence time, place, duration and intensity are determined by the location in relation to inter-tropical discontinuity. This brings about seasonality. The seasons in Nigeria is easily distinguished based on amount of rainfall, relative humidity and temperature. However, in recent times, it appears that these characteristics are gradually changing.
