The slaughtering of animals and processing of meats for human consumption generates enormous wastes which are not properly managed in most developing nations including Nigeria. Majority of people in Akwa Ibom state in southern Nigeria depend on meat as their major source of protein, and abattoir wastes are applied in farms as organic manure by some farmers. This study examined the role of abattoir-related waste products in the physicochemical properties, total metal, and metal speciation of the soil. The data obtained were also subjected to some treatments using some environmental models to establish the degree of contamination by the parameters determined, studied locations, and the associated human health problems. Samples were collected from 5 designated abattoirs in Akwa Ibom state. Thirty composite samples were used for the research. Results obtained showed higher levels of pH, electrical conductivity, organic matter, and cation exchange capacity in the abattoir waste–impacted soils than in the control plot. Levels of pseudo total heavy metals were also higher in the studied soils than in the control plot. The mean values of the metals are below 400, 85, 140, 36, 100, and 35 mg/kg of recommended limits for Fe, Pb, Zn, Cu, Cr, and Ni, respectively by the Federal Environmental Protection Agency (FEPA) in Nigerian soil. The results also revealed that Fe and Cr existed mainly in residual fraction. However, Zn, Cu, and Ni existed principally in the form bound to organic matter/sulfide. In addition, we detected that Pb existed mainly in the reducible fraction. Disparities were also observed in the speciation results of the metals between the studied soils and the control plot. Principal component analysis (PCA) indentified that both the geogenic and anthropogenic factors contributed to the accumulation of metals determined in the studied soils. Variable relationships were also observed for the heavy metals determined in the studied soils. Fe showed a high-risk potential, and children were more vulnerable due to its toxicity. We conclude this study was able to expose the consequences of indiscriminate dumping of abattoir wastes on the quality of soil and the associated human health problems.

“…An airborne lead concentration near urban agglomerations can exceed 20.000 ng m -3 , while its natural content is 0.5-10 ng m -3 . The optimal lead content in tree leaves is 1.5-7.8 mg Pb kg -1 DW, but in polluted areas it can be several times higher (PolKoWSKa et al 2001).…”

In 1970-2000, the state of the natural environment in many regions of Poland was unsatisfactory. This situation has been improving since the integration with the European Union, mainly owing to the reduction of emissions of sulphur and nitrogen oxides. The present study included three tree species: rowan (Sorbus aucuparia L. em. Hedl.), small-leaved lime (Tilia cordata Mill.), and aspen (Populus tremula L.). The trees grew in a pollution free environment (Huszlew) and in an urban agglomeration (Lublin). The aim of this research was to make comparative observations of the structure of leaves in relation to the content of lead, zinc, copper, nitrogen and sulphur determined in these organs. The N/S ratio in the leaves was accepted as an indicator of proper metabolic processes. Observations of leaves were made with using light microscopy and the scanning electron microscopy (SEM) technique. The content of heavy metals in leaves was determined by atomic absorption spectrometry (AAS) after dry mineralization. Total sulphur was determined by the turbidimetric method, while nitrogen by the Kjeldahl method after mineralization in sulphuric acid. When influenced by polluted air, the epidermis of the examined leaves was composed of smaller cells with higher stomatal density per unit area and had a lower number of open pores compared to the epidermis of the leaves developed in a clean environment. Among the species investigated, aspen was characterized by the highest ability to bioaccumulate heavy metals in its leaves. Among the elements determined only the Zn content exceeded the permissible limit, whereas Pb and Cu were found to occur in the range of values

Atmospheric deposition rates of heavy metals (As, Cd, Co, Cu, Hg, Mn, Ni, Pb, and Zn) were determined from July 2009−December 2010 in downtown Toronto. Atmospheric deposition samples were collected using samplers with plastic, glass and water surfaces from two rooftops (15 m and 59 m above ground) in the city core of Toronto. Mercury species were analyzed using Cold Vapor Atomic Fluorescence Spectrophotometer (CVAFS) and the rest of metals were analyzed by acid digestion combined with Inductively Coupled Plasma Atomic Emission Spectrometry (ICP-AES). The results showed that the deposition of heavy metals was higher on water surface as compared to both the plastic and glass surfaces and that Cu, Mn, Pb and Zn showed higher deposition rates as compared to As, Cd, Co and Ni. The deposition rates were higher on Kerr Hall North (KHN) site indicating contribution from local sources. For total mercury (THg) and methyl mercury (MeHg), the deposition rates were higher on Jorgenson (JOR) site as compared to KHN site.
