Pesticide residues in rivers of a Brazilian rain forest reserve: assessing potential concern for effects on aquatic life and human health

Article Abstract:

Pesticide residue measurements were taken from Brazil's Parque Estadual Turistico do Alto Ribeira, a rain forest reserve, between 1998 and 2000. Several pesticide levels found in water samples were above safe drinking water standards recommended by either the European Union and/or the Brazilian government, emphasizing environmental and health concerns.

Tropical forests can suffer from a serious deficiency of calcium after logging

Article Abstract:

Research indicates that timber harvesting can cause a significant depletion of soil calcium content due to the loss of logs and other biomass. Data are obtained from a forest region in Sabah, Malaysia, in which the removal of stem wood and bark resulted in a nearly 19% decrease in ecosystem calcium down to a soil depth of 50 cm.
