Abstract: the presence of the heavy metal nickel in plants growing in soils treated with sewage sludge can be a restraining factor for using this waste in agriculture. the aim of this paper was to evaluate nickel availability and absorption by sorghum plants in soil treated with sewage sludge contaminated with increasing doses of nickel. the experiment was carried out in a greenhouse, in pots, using samples of a typic haplustox. soil samples were collected 0 and 128 days after the experiment was established. the statistical design adopted was completely randomized, with five treatments (four doses of nickel in the sewage sludge and one control without sewage sludge and only with mineral manure) with four replicates. the application of sewage sludge contaminated with increasing doses of nickel resulted in proportional increasing contents of "total" and available nickel in soil. mehlich-1 and mehlich-3 extracted the highest concentrations of nickel in this soil. mehlich-3 was the extractant that obtained the highest correlation with the concentrations of nickel in sorghum plants. with the increasing concentrations of nickel in the soil occurred an increase in the absorption of this heavy metal by 39.93; 101.16; 152.58 e 171.38 %, by sorghum plants.

Revista Brasileira de Ciência do Solo , 2005, DOI: 10.1590/S0100-06832005000400018
Abstract: this study evaluated the kinetics of urease hydrolysis in two different brazilian soils (rhodic oxisols): a typic alumino-ferric red latossol and a typic distrophic red latosol. the trials were carried out to study the effects of air drying, soil sampling, storage conditions and temperature, ph, time of incubation, and substrate concentration on the urease activity. results showed that best conditions for soil sample storage after air-drying for a 7-day period were at room temperature or at a temperature of 5 oc. for the studied conditions the best incubation time was one hour at 25-30 oc, without ph buffering. the ideal urea concentration suggested for the detection of the maximum velocity was 3.3 g l-1 for the typic alumino-ferric red latossol and 2.5 g l-1 for the typic distrophic red latosol.

Abstract: the role of nickel in soils of tropical areas under the application of sewage sludge is still not very well known. this study was carried out under greenhouse conditions in jaboticabal, s?o paulo state, brazil, with the objective of evaluating the impact of the application of sewage sludge previously contaminated with rates of nickel (329, 502, 746 and 1119 mg kg-1, dry basis) on a soil cropped with sorghum, in relation to soil enzyme activity and soil microbial biomass. soil samples were collected at the beginning and the end of the experiment. the experimental design was completely randomized, with five treatments (control and four rates of ni in the sewage sludge) and four replications. c and n of the soil microbial biomass and enzyme activities (acid and alkaline phosphatases) were sensitive indicators for impact evaluation caused by sewage sludge contaminated with nickel. there were positive correlations between "total" and extractable nickel (mehlich 1) with c-microbial biomass and negative with the microbial c/n relationship. n-microbial biomass correlated positively with "total" and extractable ni at the last sampling. at the end of the experiment, the acid phosphatase activity correlated negatively with "total" ni while the alkaline phosphatase correlated with both forms of the metal.
Air Quality Monitoring and Its Implication on the Environmental Licensing Process in Brazil  [PDF]
José Carlos de Moura Xavier, Wilson Cabral de Sousa Junior
Journal of Environmental Protection (JEP) , 2014, DOI: 10.4236/jep.2014.51001
Abstract:

In the state of Sao Paulo, Brazil, public policies regarding the air quality aimed at the welfare of the population are strongly dependent on monitoring conducted by the Sao Paulo State Environmental Company (CETESB), which can be influenced by faulty monitors and equipment support and cuts in power supply, among others. A research conducted from 1998 to 2008 indicated that a significant portion of the air quality automatic stations in the state of Sao Paulo did not meet the criterion of representativeness of measurements of PM10, NO2, O3, CO and SO2 concentrations which resulted in the classification of some municipalities as the nonattainment area, a situation evidenced for PM10 and O3 parameters. The network unavailability for each parameter was estimated and compared with the monitoring networks operated in Canada and the UK. This paper discusses the implications of the lack of representativeness of measurements in the environmental licensing process of pollution sources from 2008, when by the effect of state law, municipalities have been qualified according to their air quality nonattainment level.
