Environmental pollution by heavy metals within the area influenced by the Tungurahua volcano eruption - Ecuador.

Volcanic eruptions can have long-lasting negative effects on nearby environments and communities, especially those relying on agriculture. The Tungurahua and Sangay volcanoes in Ecuador's highlands pose a significant risk to the region's agricultural economy and inhabitants. The most recent eruption of the Tungurahua volcano spanned from September 1999 to March 2016.

Inorganic arsenic content in Ecuadorian rice-based products.

Arsenic intake in the world is linked with drinking water and food; the main sources of inorganic As (i-As) exposure in food are rice and rice-based products. The consumption of rice in Ecuador is 53.2 kg year and it is the most commonly used cereal for the preparation of many popular dishes especially for subjects with celiac disease.

Development of organic fertilizers from food market waste and urban gardening by composting in Ecuador.

Currently, the management of urban waste streams in developing countries is not optimized yet, and in many cases these wastes are disposed untreated in open dumps. This fact causes serious environmental and health problems due to the presence of contaminants and pathogens. Frequently, the use of specific low-cost strategies reduces the total amount of wastes.

Agroindustrial compost as a peat alternative in the horticultural industry of Ecuador.

This work was conducted in order to investigate the possibility of using different agroindustrial composts in the production of horticultural seedlings, thereby replacing part of the peat in the growing media. Three vegetable species differing in salt sensitivity - tomato (Solanum lycopersicum L. var.

Windrow composting as horticultural waste management strategy - A case study in Ecuador.

In Ecuador, enormous quantities of vegetable wastes are produced annually from the horticultural industries. Composting can be a feasible treatment to stabilise horticultural wastes and, thus, to improve their properties for use as organic fertilisers. In this study, two different piles were prepared, using laying hen manure and sawdust mixed with broccoli or tomato waste, respectively, and composted by the turned windrow composting system.
