The study shows that the river basin is a veritable sewer, containing cyanide, lead, arsenic, cadmium and mercury, used in mining, coliform bacteria from human waste, and nitrates from agrochemicals. He has signed an agreement to implement urgent measures with the local social organisations that produced the report.

Lead was found throughout the basin, particularly in the Anticona river, where it was found at concentrations times higher than the WHO reference levels and the quality baseline used in the study.

The local quality baseline was established by experts on the basis of analysis e, from the water in nine rivers, sampled near their sources, where the water is regarded as the cleanest in the basin.

In the Yauli river, which forms part of the Mantaro basin, lead levels are three times higher than the Class III reference level, the Peruvian standard for agricultural and livestock use. After the tributary flows through La Oroya, its lead levels are 16 times revkve than the water quality baseline adopted by the study.

It has also been ranked as one of the 10 most polluted cities in the world, according to the non-governmental Blacksmith Institute, based in New York. Samples taken from the Mantaro river in La Oroya contained five times the permitted refive level for Class I water fit for human consumptionand 23 times the baseline level. The metal smelting plant of the U. Samples taken at mahtaro locations along a km mangaro of the Mantaro basin showed that the Yauli river and the San Juan river, which flows into lake Chinchaycocha, have the highest concentrations of cyanide, lead, arsenic, cadmium and mercury.

In the San Juan river and the outflow from the Huascacocha lagoon, cyanide concentrations are up to 35 times higher than the baseline level. Two irrigation channels are loaded with large amounts of heavy metals. The Meris-Orcotuna irrigation channel, on the right-hand bank of the Mantaro, has 1. In order to ensure the independence of the scientific report, 10 Peruvian experts and five researchers from the St.

The study manraro made more rigorous by collecting samples at hourly intervals throughout the day. Sequential monitoring of chemical compounds in multiple samples leads to greater precision in the results, and allows identification of peak pollution times. The study also highlights environmental harm reflected in the total coliform bacteria counts, which are well above the standards set by Peruvian law and the quality baseline in the Yauli river where it flows through La Oroya, and in the Chilca and the Shulcas rivers.

As for nitrates, le concentrations found in the Anticona river are 56 times greater than the Class I levels, while in the Achamayo and Shulcas rivers, nitrates are present at 60 times the Class I reference concentration. The report emphasises that the presence of nitrates is associated with the use of agrochemicals in the Mantaro river valley, an important farming region. Researcher Fernando Serrano at St.

Louis University said that the principle of proportionality should apply when the costs of damage remediation are allocated. Those who pollute the most should pay most of the clean-up costs, devive said. For her part, Meza told IPS that these initial results are a big step forward.

The central government is to rvive these powers over to the regions next month. As a first step, Lanegra told IPS he would try rebive fill the legal vacuum in relation to water quality standards, because Peru has only one law to regulate water use, which dates back to the s.

The same action would be taken to regulate soil quality, he said, an area in which Peru lacks national legislation. In the historic quarter of the city of La Oroya, arsenic levels measured in topsoil are times the Canadian standard of 12 micrograms per kilogram of soil, and cadmium levels are times the Canadian maximum permitted levels.

In Orcotuna, an area of artichoke cultivation which is irrigated mntaro water from the Mantaro river, significant amounts of cadmium, arsenic, zinc and copper have been detected in the soil.

Apart from these alarming findings, the authors of the study conclude that Peruvian legislation does not protect human health and environmental quality effectively, in comparison with the laws in other countries. Related Tags City Voices: The Week with IPS.
