The aim of this study was to detect heavy metal concentrations in the creek which passes through Nigde city garbage dump. In this respect, the soil samples collected in the study area by GPS were analyzed using X-Ray Fluorescence Spectrometer. Traces of heavy metals were observed by using statistical programs on analysis results. Geological observations were taken into consideration. According to the heavy metal concentrations in the Creek, the maximum values were as follows; (mg/ kg) Ti: 4960, V: 520, Cr: 120, Mn: 810, Ni: 460, Cu: 410, Zn: 100 and Pb: 480. The concentration levels of heavy metals in soil caused by garbage dump are listed in the following order; Pb > Cu > V > Ti > Cr > Ni > Zn. High positive correlation were observed between Ti-Mn, V-Ni and Cr-Ni. Medium positive correlations were observed between V-Cr, V-Cu and Ni-Zn. It has been found by chemical analysis data collected from stations established throughout the creek that there is an effect of morphological structure and no geological anomaly has been formed. According to chemical analysis results, statistical programs give important accuracy. Heavy metals, which give anomaly, differ throughout the creek. The source of these heavy metals was determined as Nigde city garbage dump. For this reason, it was suggested that, in order to refine the study area, a modern, organized storage system must be used instead of wild storage system in storing the urban wastes, and recyclable products must be used in the industry.

Celem pracy było ustalenie, które z badanych roślin (topola, wierzba wiciowa, rzepak, konopie i mieszanka traw) kumulują największe ilości cynku oraz jak zróżnicowany stopień nawadniania gleby wpływa na pobranie tego pierwiastka. Eksperyment przeprowadzono na polach doświadczalnych (gleba torfowo-murszowa) irygowanych ściekami miejskimi o II stopniu oczyszczenia. Pola doświadczalne były podzielone na trzy kwatery: kontrolną (A), zalewaną pojedynczą dawką, ścieków miejskich po II stopniu oczyszczenia (B) oraz zalewaną dawką podwójną (C), Ilość ścieków wprowadzanych na pola wynosiła odpowiednio 600 i 1200 mm w ciągu roku. Oznaczenia stężeń cynku w materiale roślinnym wykonywano metodą absorpcyjnej spektrometrii atomowej (AAS). Stężenia cynku mieściły się w zakresie 11-290 mg kg '. Najwyższą zawartość cynku stwierdzono w liściach topoli, 32-290 mg kg-1. Pozostałe rośliny można uszeregować następująco; wierzba, konopie, rzepak, mieszanka traw.

Waste management is the collection, transportation, processing, recycling or disposal of waste materials. The term usually relates to materials produced by human activity and is generally undertaken to reduce their effect on health, aesthetics, amenity and the environment and also to recover resources. Waste management can involve solid liquid or gaseous substances with different methods and fields of emphasis for each. Waste management practices differ for developed, developing nations, for urban and rural areas, and for residential and industrial production. This paper tries to deal with illegal and unplanned solid waste disposal; it also attempts to proffer solutions to the problem of improper waste disposal through incineration and recycling of metals, cellophane and Teflon and how Bauchi state can generate some revenue through the recycling of these waste materials. The paper also tries to educate on the problems associated with landfills while dealing briefly, on the advantages of biological processing and also how waste can be avoided and reduced. The paper also tries to present waste management concepts in relation to Bauchi city.

This study was conducted in order to determine if inoculation with arbuscular mycorrhizal fungi (AMF) and soil amendment with compost would enhance the tolerance of fountain grass to high level of salinity and alkalinity found in urban soils. AMF-inoculated and non-inoculated plants were planted in growing media non-amended and amended with compost and irrigated with water containing 3.3 g NaCl∙dm-3, 10.5 g Na2CO3∙dm-3, or 6.3 g CaCl2∙dm-3. Electrical conductivity (EC) of each watering solution was 6.3 S∙m-1. Plants were watered with salty waters every week until some leaves were necrotic. All the investigated salts decreased the decorative value of fountain grass and the percentage of root colonization by AMF. NaCl and Na2CO3 also decreased the dry matter of plants. Mycorrhization improve growth parameters and aesthetic value of fountain grass treated with all the tested salts and cultivated without compost supply. Compost supply was beneficial for fountain grass growth and quality if plants were cultivated in substrates unpolluted with NaCl, CaCl2, and Na2CO3.
