| The Atlantic Forest on the slopes of Serra do Mar around Cubatão (São Paulo, Brazil) has been affected by massive emissions of pollutants from the local growing industrial complex. The effects of air pollution on the amounts of leaf nitrogen, total soluble phenols and total tannins of Tibouchina pulchra Cogn., a common species in the area of Cubatão, were investigated, as well as the possible influence of the altered parameters on the leaf area damaged by herbivores. Fully expanded leaves were collected at two sites: the valley of Pilões river (VP), characterized by a vegetation virtually not affected by air pollution and taken as a reference; and valley of Mogi river (VM), close to the core region of the industrial complex, and severely affected by air... |

| Several aspects of nutrient cycling were studied at two sites of Atlantic Forest, in São Paulo State, Southeast Brazil (23o46 S; 46o18 W), which exhibited different degrees of forest structure decline caused by the air pollution emitted by the industrial complex of Cubatão, being referred here as the most and least affected sites (MAS and LAS, respectively). These investigations were developed during 1984 - 1986, a period in which the most severe negative effects of air pollution could be observed. Concentrations and amounts of N, P, K, Ca, Mg and S in four ecosystem compartments (leaves, litter layer, soil and roots) and in rainfall, throughfall and litterfall are briefly presented. At each site, the content of mineral elements generally decreased from... |

| Estudos epidemiológicos mostram uma relação entre a poluição aérea em centros urbanos e a taxa de doenças respiratórias na sua população. Em São Paulo, a concentração dos principais poluentes aéreos é monitorada pela CETESB porém, tais dados não dão idéia do risco ao qual a população está sujeita; plantas bioindicadoras podem dar idéia deste risco. O clone híbrido 4430 de Tradescantia vem sendo utilizado em bioensaios (Trad-MCN, Trad-SH) que avaliam o efeito genotóxico de várias substâncias. Não há registros das potencialidades de bioindicação relativas à estrutura das folhas do clone. Este estudo objetivou estabelecer o padrão estrutural da folha do clone e verificar se existem características anatômicas afetadas pela poluição, que podem ser utilizadas... |
