“…Scholars conclude that highway environments are highly polluted due to emission from vehicles, and they confirmed that soil, water, and air around busy roads have significantly higher lead content than nonbusy roads [10]. This claim is supported by other researches indicating that vehicular emission is responsible for more than 90 percent of all atmospheric emission and roadside soil lead content [11]. There is also a strong positive and direct relationship between roadside soil lead and traffic density of the road [12].…”

Objective. The aim of this research was to compare blood lead level of childbearing women near Addis Ababa-Adama highway with those who live far from it.Study Design. A comparative cross-sectional study design was used to compare blood lead levels of 40 childbearing women (study group) who lived relatively near Addis Ababa-Adama highway and other 36 childbearing women (comparative group) who lived relatively far (10 km) from the highway.Methods. In the study, women having a fertile age within 15–49 years were considered as “childbearing women.” Blood samples were collected from each group and analyzed for blood lead level comparison.Result. The study indicated significant blood lead level difference (p<0.001) between the groups. The study group had higher blood lead level (34.32 ± 6.39 μg/dL) than the comparative group (8.47 ± 3.01 μg/dL). The mean blood lead level of both groups was higher than the advised blood lead concentration for a woman to avoid occupational or vocational lead exposure.Conclusion. This study concluded that blood lead level of women who lived relatively near Addis Ababa-Adama highway was significantly higher than those who lived relatively far from the road.

Abstract:The physicochemical composition of harvested soursop (Annona muricata L.) fruits from Coast region,Tanzania, during open-air storage was determined. The ash, titratable acidity, crude fat, crude fiber, moisture and sugars content were determined by proximate analysis. Ascorbic acid contents were determined using the 2,6-dichlorophenol-indophenol dye method while macro-nutrients and heavy metals were determined by Flame Atomic Absorption Spectrophotometry (FAAS). The fruits were harvested at the mature ripe stage and kept in open air storage over several days. The determinations were done immediately after fruit arrival at the laboratory and thereafter at intervals of two days from the day of harvest. The results showed that soursop fruits had high moisture content (73.1% -82.1%), low titratable acidity (0.10 -1.25% ca), low crude fat (0.42 mg/100 g-fw), moderate ash content (0.87 mg/100 g-fw) and crude fibre content (6.09 mg/100 g-fw), high ascorbic acid content (34.0 -19.7 mg/100 g-fw), high total sugars content (34.3% -45.3%), reducing sugar content (18.9% -39.2%) and sucrose content (15.5% -30.0%). Of the macroelements Na, Ca and K, the average content were 895.6, 870.3 and 367.5 mg/100 g-fw respectively. Heavy metals (Fe, Zn, Cu, Pb and Cd) content was very low in the soursop fruits, ranging between <0.0015 mg/100 g-fw for Cd and 0.82 mg/100 g-fw for Fe. During storage, the moisture content, titratable acidity level and sugars content in the fruit were all increasing whereas the ascorbic acid content was decreasing. There were no significant changes during storage for levels of crude fat, fiber, ash, mineral elements and heavy metals. The findings from this study suggest that this fruit from coast region of Tanzania can contribute nutritionally to the health of the consumer.

Abstract:The physicochemical composition of pomegranate (Punica granatum L.) fruits from Kimara, Dar es Salaam during open air storage ripening process were determined. The ash, titratable acidity, crude fat, crude fiber, moisture and sugars content were determined by proximate analysis. Ascorbic acid contents were determined using the 2,6-dichlorophenol-indophenol dye method while mineral elements and heavy metals were determined by Flame Atomic Absorption Spectrophotometry (FAAS). The fruits were always harvested at the mature stage and allowed to ripen during open air storage. The determinations were done immediately after arrival at the laboratory and thereafter at intervals of two days from the day of harvest to the 8 th day. The results showed that fresh pomegranate fruits had high moisture content range of (89.6%-77.5%), low titratable acidity (<0.86% ca), low crude fat (0.30 g/100 g-fw), low ash content (0.35 g/100 g-fw), moderate crude fibre content (4.20 g/100 g-fw), high ascorbic acid content (53.7 -20.4 mg/100 g-fw), high total sugars content (48.9% -29.1%), moderate reducing sugar content (42.0% -25.5%) and sucrose content (5.7% -2.0%). Of the mineral elements (K, Ca and Na) determined, the highest content was of Ca (1086 mg/100 g-fw.). Heavy metals (Fe, Zn, Cu, Pb and Cd) content was very low in the pomegranate fruits, ranging between <0.0015 mg/100 g-fw for Cd and 0.84 mg/100 g-fw for Fe. Except for sucrose which was increasing during storage ripening, the moisture content, acidity content, ascorbic acid content, total sugar content and reducing sugar content were all decreasing as the fruit was ripening while in storage. There were no significant changes during storage ripening for levels of crude fat, ash, minerals and heavy metals. The results of this study suggest that these fruits could highly contribute in the improvement of the nutrition of consumers.
