“…This result can be explained due to the high levels of trace elements found in the sludges (Table 2) which, according to Lopes et al (2004), may raise the levels of Zn to toxic levels in soil, thus increasing the possibility of nutrient transference to the entire food chain (Alloway, 1995).…”

ABSTRACT:The composition of organic waste (OW) and its effect on soil processes may change soil fertility and electrical conductivity (EC). The side effects of waste use in crop fertilization are poorly understood for Brazilian soils. This study examined the effect of the addition of 15 different organic wastes to Oxisols and a Neosol on pH, base saturation, EC, cation exchange capacity (CEC at pH 7), and the availability of Al, macro (P, K, Ca 2+ , Mg 2+ and S) and micronutrients (B, Fe 2+ , Mn 2+ , Cu 2+ and Zn 2+ ). Soil samples (150 g) were treated with chicken, pig, horse, cattle, and quail manures, sewage sludge 1 and 2, eucalyptus sawdust, plant substrate, coconut fiber, pine bark, coffee husk, peat, limed compost, and biochar. Wastes were added considering a fixed amount of C (2 g kg -1), which resulted in waste rates ranging from 2.5 to 25.6 Mg ha -1 . The soil-waste mixtures were incubated for 330 days in laboratory conditions. The waste liming or acidification values were soil-dependent. The use of some manures and compost increased the pH to levels above of those considered adequate for plant growth. The soil EC was slightly increased in the Neosol and in the medium textured Oxisol, but it was sharply changed (from 195 to 394 µS cm -1) by the addition of organic wastes in the clayey Oxisol, although the EC values were below the range considered safe for plant growth. Changes in the soil availability of P, K + , Ca 2+ and Zn 2+ were highly related to the inputs of these nutrients by the wastes, and other factors in soil changed due to waste use. Organic waste use simultaneously affects different soil fertility attributes; thus, in addition to the target nutrient added to the soil, the soil acidity buffering capacity and the waste liming and agronomic value must be taken into account in the waste rate definition.

“…The considerable contribution of natural processes to the mobilization of metals in the aquatic environments is a consequence of weathering of rocks and leaching of soils (SAHOO et al, 2017). In turn, anthropic contribution results from a number of factors, like mining activities (RIBEIRO et al, 2017), the misuse of soil in agriculture, and the discharge of untreated industrial and domestic effluents (LOPES et al, 2004). Every year tons of metals are mobilized through soil, air, and water, and are inevitably incorporated in food chains, with hazards to human and environmental health (NRIAGU;PACYNA, 1988;BUBB;LESTER, 1991;LOPES et al, 2004).…”

The studies on metals in Madeira River’s principal flow show high variability of Co, Cr, Cu, Fe, Ni, Pb and Zn concentrations. However, the transfer of these metals from the main river channel, whose physical and chemical characteristics differ from those of lakes, has not been fully characterized. The objective of this study was to discuss how the transfer of Madeira River’s metals changes the spatial dynamics of these metals in sediments of the Puruzinho Lake (AM). The principal component analysis pointed to differences in the order of the data, creating two distribution zones of metals. The average concentrations of Co, Cu, Cr, Mn and Fe are higher in the area under the influence of the suspended solids coming from the Madeira River. The zoning of metals in lakes is structured by the forces acting across the river’s course at the same time as plains flood and generates ecotones.

“…Para os outros parâmetros de parte aérea, todos os tratamentos se comportaram de forma semelhante, segundo CONTE E CASTRO et al A recomendação de CONTE E CASTRO et al (2001a), para uso de composto de lixo urbano, na composição de substrato para a cultura do ipê roxo, está na maior produção do sistema radicular, importante característica para essa cultura, já que é levada para o campo nas mais adversas condições. LOPES et al (2003), trabalhando com a cultura do crisântemo, utilizando resíduo industrial de galvanoplastia como fonte de nutrientes, observaram que doses acima de 3,0 g L -1 , ocasionaram um desequilíbrio nutricional, fitotoxidez de Zn, resultando em diminuição da produção. CONTE E CASTRO et al (2005), trabalhando com composto de lixo urbano e lodo de esgoto no desenvolvimento das variedades Bi Time e Day Drean de crisântemo, observaram que as diferenças na produção de ambas as variedades estavam mais ligadas à sua própria genética, do que aos resíduos utilizados.…”

O presente trabalho teve como objetivo avaliar o desenvolvimento de crisântemo de corte utilizando composto de lixo urbano e lodo de esgoto. O experimento conduzido sob cultivo protegido, na Fazenda Experimental de São Manoel, da Faculdade de Ciências Agronômicas da UNESP, Campus de Botucatu. O solo é um Latossolo Vermelho-Amarelo distroférrico. O delineamento experimental distribuído em blocos ao acaso, foi um fatorial 2x4, com dois resíduos (composto de lixo urbano e lodo de esgoto) e quatro doses (0, 10, 20 e 30 t ha-1 composto de lixo urbano e lodo de esgoto). Foram avaliados no final do ciclo da cultura: a altura de plantas, o diâmetro de plantas, o número de folhas, a área foliar e massa seca de hastes, as folhas e o total da planta, o número, o diâmetro e a massa seca das inflorescências e o número de hastes secundárias. Os dados foram avaliados pelo programa STAT. Os resultados permitiram concluir que nas condições experimentais o composto de lixo urbano e o lodo de esgoto, nas diferentes doses utilizadas, não se foram eficazes na produção do crisântemo de corte da variedade Calábria.
