lead, cadmium and iron concentrations in zea mays grownstudy conducted by olusoga and osibanjo [30] at olodo ibadan touched on concentration of lead and cadmium, on the whole maize plants, the present study is designed to determine the concentration of pb, cd and fe in different parts of cultivated maize plant, namely, the roots, stem,heavy metals levels in forage grasses, leachate andreared around lead slag dumpsites in nigeria ogundiran, m. b. *, ogundele, d. t., afolayan, p. g. and osibanjo, o. analytical/environmental unit, department of chemistry, university of ibadan, ibadan, nigeria abstracta field study was conducted around pb slag contaminated sites in ibadanappraisal of lead in the organs and tissues ofthe main objective of the study includes the assessment of the concentration of lead (pb) in chicken organs widely consumed in ibadan city, nigeria and to compare with international guideline standards. material and methods study area this study was undertaken in ibadan city which is located near the forestgrassland boundary of southwesternblood lead and tap water lead levels in ibadan, nigeriajul , 94· blood lead levels of a segment of the population in ibadan were determined using atomic absorption spectrophotometry. mean blood lead levels of .4 μg/dl and .3 μg/dl were recorded for females and males, respectively. tap water lead levels at various locations in the city were < 5 μ g/l. although current levels of lead in the environmentstudies on the concentration of lead in ibadanstudies on the concentration of lead in ibadan_roadside topsoil concentrations of lead and other heavy jun 24, 10· an average of about 60% of total soil concentration of the metals were determined to be held in bioavailable geocecological and health risk studies of heavy metals inview that provoked the study, more so as little or no study has been done on the surrounding soil of the abandoned battery industry. the present study tends to evaluate the ecological and ecological and health risk studies of heavy metals in soils around an abandoned battery factory in ibadan, southwestern nigeria.

Advantages of studies on the concentration of lead in ibadan

open land dumping an analysis of university of ibadanlead is explainable with the fact the study location is lead battery dump site. thus, the study location is polluted with lead due to the anthropogenic effect and this pose hazards to human health as high concentration of pb when exceeded the thresh levels has been reported to be toxic andassessment of air pollutant concentrations near majormar 29, · the overall average nox concentration of 63± μg/m 3 obtained in ibadan is similar to nox concentrations in most urban outdoor air, which have been found to fall within the range of 90 μg/m 3.3638. in this study, the maximum ozone concentration of 61± μg/m 3studies on the concentration of lead in ibadanpollution studies on nigerian rivers the onset of leadon dec 31, 83 c. mombeshora (and others) published pollution studies on nigerian rivers the onset of lead pollution of surface watstudies on the concentration of lead in ibadanlead, cadmium and iron concentrations in zea mays grownmay 05, · available literature has shown that maize absorbs and accumulates toxic heavy metals from polluted soils. this study was designed to determine the concentration of lead (pb), cadmium (cd) and iron (fe) within the leaf, stem, grains and root of maize grown on oriile battery waste dumpsite, olodo, ibadan nigeria.heavy metal concentration in selected fish species fromplantation, pmb 5029 ibadan, oyo state, nigeria. received march, ; accepted july, heavy metal concentrations (lead, cadmium, zinc, copper, chromium and manganese) in selected fish species from eleyele reservoir ibadan oyo state southwestern nigeria were investigated. a samplewater quality assessment of eleyele dam, ibadan,southlead contamination is toxic, the bioaccumulation of lead in body tissues has neurotoxic, nephrotoxic, fetotoxic, and teratogenic effects on man and animals. (asogwa, 79; hoekman, 05). previous studies on lead contamination in ibadan has shown a high level of lead deposit (adelekan andequilibrium, thermodynamic and kinetic studies on thegovernment area, enugu state, nigeria. the aim of this study was to investigate the potential of agbani clay as a lowcost adsorbent for lead(ii) ions from industrial wastewaters. the adsorption experiment was performed using batch technique to investigate the effect of ph, initial metal ion concentration, temperature and time.
