“…The powder samples were sieved and suspended in a resuspension chamber or separated by a Bahco centrifugal machine. The sampling methods referred to their relative studies (Chow et al, 1994;Chan et al, 1997Chan et al, , 1999Wilson et al, 2002). A sea salt profile and a biomass burning profile in speciate 4.2 from US EPA were used.…”

PM 10 samples were collected from five northern Chinese cities (Tianjin, Anyang, Ji'nan, Kaifeng and Taiyuan) during the winter and summer months. Carbonaceous species concentrations in the PM 10 samples from these cities were then measured. The concentration values show that PM 10 , organic carbon (OC) and elemental carbon (EC) exhibited relatively high concentrations during winter months as opposed to the summer months for all five cities. The contributions from primary and secondary sources were estimated using the Chemical Mass Balance (CMB) and the CMB-Iteration models. The results of two models were comparable, and results showed that the coal combustion and crustal dust were the most important source categories for both seasons. Additionally, seasonal variations of species mass fractions in receptors were analyzed, as well as variations in the estimated source percentage contributions. Seasonal variations of species mass fractions agreed with the variations of source percentage contributions for the five cities. Finally, primary organic carbon (POC) and secondary organic carbon (SOC) concentrations, and their seasonal variations, were estimated. We found that SOC showed relatively high concentrations (μg/m 3 ) in the winter, while the SOC/TOC ratios in the summer were higher than those in the winter.

“…Surface physicochemical processes determine material conversion (Rita et al, 2006), energy transfer, and chemical conversion on the surfaces of aerosol particles (Peterson et al, 2006;Chan et al, 1997). Such transformations in aerosol particles affect both the environment and human health Tang et al, 2006;Wei et al, 2009).…”

“…Though, the high Cu concentration in Point A could also be due vehicular and exhaust emissions [40,41]. The high Cd concentration experienced is attributed to high local metallurgical activities that occur in the area, vehicular, exhaust emissions and traffic emissions [39,40,41].…”

“…The increase in white blood cell could be associated with an increase in antibody production in response to the extracts which help in long survival of the mice exposed [44]. Changes in haematological values occur in relation to physiological stress, diseases and toxic environmental conditions [40]. The fluctuation in the mean corpuscular volume (MCV), mean corpuscular haemoglobin (MCH) and mean corpuscular haemoglobin concentration (MCHC) in the present study, clearly indicates that the concentration of haemoglobin in the red blood cells were much lower in the exposed mice than in the control mice, depicting aneamic condition.…”

Introduction:The ecological equilibrium of the earth is endangered by the chemical process industries as most industries continue to spew chemical toxicants into the environment. Since local metallurgical activity is inevitable in Nigeria. Aim: This research is aimed at assessing the effect of heavy metals air pollution arising from local metallurgical activities on Albino rat. Methods: Particular matter samples were collected for 24h at four different sites twice a month using a high volume air sampler. Point A is Bakin Dogo Market, Point B is Old Panteka market, Point C is new Panteka market and Point D is U/Ma'azu. All the collected samples were analyzed for heavy metals using standard laboratory procedures. Six hundred newly born male albino rats were collected from National Institution for Trypanosomiasis Research (NITR) and were exposed to the sampling points twenty four hours daily via out the experimental period. Mortality, haematological and histological parameters were investigated. The rat tissues were also digested for the determination of Bioconcentration factor (BCF).Result: The result obtained shows high Concentration of heavy metals (Pb, Cd, Cu and Ni) above the recommended limit by European commission (EC), World health organization (WHO) and NEPM (National Environmental Protection Measures). Higher BCF was obtained for all the heavy metals (Pb, Ni, Cu and Cd) which was attributed to the higher changes in Mortality, haematological and histological parameters if compare to the control. Conclusion:The studies shows how heavy metal air pollution could cause Mortality and also bring about changes in haematological and histological parameters, which resulted due to high BCF. It is thereby recommended that local metallurgical activities should be closely monitored by environmental agencies such as Kaduna state environmental protection agencies (KEPA) and Federal environmental protection agencies (FEPA). The government should also make regulations that will mandate the paying of environmental degradation tax owing to the daily multiplication of vehicles and other automobile materials.
