The main goal of this work is to assess the concentrations of total suspended particles (TSP) and airborne particulate trace metals in the Industrial District of Santa Cruz, Rio de Janeiro, Brazil, where the main pollution sources are the local industries. The sampling was performed using a high-volume pump. The TSP levels were determined by gravimetry and the metals by inductively coupled plasma atomic emission. A geometrical mean of 87 +/- 40 mug m(-3) was determined for TSP for the period March 2001-February 2002, which is higher than both the Brazilian primary and secondary standards of air quality. Metals concentrations were compared with literature values for other regions of the world and with air quality standards of regulatory agencies. Mn, Fe, Zn, Cu, Cr and Al levels are higher than the reported values for other industrial and urban areas around the world. Mn, Cr and Ni concentrations are higher than the US-EPA standards. Cluster and principal component analysis were used to get some insight about the sources of metals and the correlations among them. |

The objective of this work was to evaluate the phytochemical profile and bioactivity of extracts of Brazilian stinging (?cansanção?) nettle (Cnidoscolus urens) on cabbage caterpillar (Ascia monuste orseis). Mortality, larval stage duration, pupal viability and mass, percentage of deformed pupae, and feeding preference were evaluated. The constituent classes of the ethanolic extracts were also identified by analytical thin-layer chromatography (TLC). Ethanolic extracts of leaves and roots at 2% (m/v) and aqueous extract of roots at 20% (m/v) prolonged the larval phase of the insect. The ethanolic extract of leaves at 2% reduced pupal viability, and pupae from all treatments showed reduced masses and generated deformed adults. Except for the ethanolic extract of stem at 2% (m/v), all other extracts showed a deterrent effect on A. monuste orseis larvae. The phytochemical analysis of ethanolic extracts showed the major presence of phenolic compounds, naphthoquinones, anthraquinones, coumarins, anthracene derivatives, terpenes, and steroids, as well as tannins. Aqueous extracts at 20% concentration and ethanolic extracts at 2% of leaves, stems, and roots of cansanção nettle cause larval mortality and also reduce leaf consumption, pupal viability, and pupal mass of A. monuste orseis. |
