This study was carried out as part of an investigation of water and sediment budgets in an ephemeral catchment in Dinosaur Provincial Park badlands, Alberta. These badlands have developed in Cretaceous mudstones, siltstones, and sandstones, with some glacial and postglacial surficial deposits. Study objectives were (i) to identify major solute sources, (ii) to show how these change with storm characteristics, and (iii) to assess the proportion of solutes in the total stream budget. Field examination, rainfall-simulation tests, and laboratory experiments showed marked variations in solute production on different lithologic surfaces. This information, when combined with data on threshold precipitation for runoff production from previous experiments, made it clear that solute production in the catchment is significantly influenced by storm characteristics. Observations indicate that in brief, low-intensity storms, runoff occurs only on sandstone, miniature-pediment, and stream-channel surfaces. Solute production on these surfaces is limited and is dominated by flushing of salts previously precipitated on the surface. In high-intensity or prolonged storms, runoff also occurs on mudstone surfaces and from subsurface tunnels. In both cases solute production is higher and increases with storm duration because of progressive mudstone dispersion. During the 12 storms monitored, the average stream-solute concentration was 308 mg L−1, which is approximately 1.4% of the total stream load.

The Impact

More than two billion people suffer from anemia worldwide, and it is estimated that more than 50 % of cases are caused by iron deficiency. In this community intervention trial, we evaluated infants aged 10 to 23 months of age (n = 171) from two public child day-care centers. Intervention lasted 18 weeks. The 50-g individual portion (uncooked) of fortified rice provided 56.4 mg of elemental iron as ferric pyrophosphate. Capillary blood samples to test for anemia were taken at baseline and at endpoint. The objective of this study was to evaluate the impact of rice fortified with iron (Ultrarice®) on hemoglobin and anemia prevalence compared with standard household rice. For the fortified rice center, baseline mean hemoglobin was 113.7 ± 9.2 g/L, and at endpoint 119.5 ± 7.7 g/L, p < 0.0001; for the standard rice center, baseline mean hemoglobin value was 113.5 ± 40.7 g/L, and at endpoint 113.6 ± 21.0, p = 0.99. Anemia prevalence for the fortified rice center was 27.8 % (20/72) at baseline, and 11.1 % (8/72) at endpoint, p = 0.012; for the control center, 47.1 % (33/70) were anemic at baseline, and 37.1 % (26/70) at the end of the study, p = 0.23. The Number Needed to Treat (NNT) was 4. In this intervention, rice fortified with iron given weekly was effective in increasing hemoglobin levels and reducing anemia in infants.
